    Toxuki released this 2026-10-16 04:57:57 +00:00 | 1351 commits to main since this release

    Kioku is a tracker for anime, manga and light novels that runs on your own computer. It is made first for Windows and works on macOS and Linux too. Your library lives in a database on your computer, syncs with AniList, MyAnimeList, AniDB, Kitsu and MangaBaka, plays your episodes in mpv or follows the player you already use, reads your manga and light novels, and lets you watch together with friends. Kioku speaks English and Slovak.

    New in 1.22.0

    • Streaming changes: when a title you plan to watch or are watching comes to one of your streaming services or leaves it, Kioku tells you (only links for your region, when you set one), and Where to watch lists the recent changes.
    • Weekly recap: on Monday morning, what you watched, read and finished last week and how many episodes air this week.
    • Snooze: put any notification in the bell off for an hour, three hours, until the evening or until tomorrow morning; it comes back unread.
    • Dubbed episodes: mark a title as watched dubbed and Kioku tells you when its dubbed episodes are out instead of the subbed ones, from AnimeSchedule's dub timetable (with your own AnimeSchedule token, in Settings > Notifications).
    • English volumes: the manga and light novels you read show the release dates of their next English volumes, from Google Books, on Home and on each title's page.

    New in 1.21.0

    • New chapters: Kioku follows the chapter count of the manga and light novels you read (where MangaBaka counts them), tells you when a new chapter is out, and Home shows how many are waiting.
    • The story goes on: a finished anime with nothing after it points to the manga or light novel it adapts, ready to add.
    • Trailer reel: the Seasons page plays the trailers of the season's shows one after another in mpv, or as a playlist in the browser.

    New in 1.20.0

    • Openings and endings: a title's page lists its openings and endings from AnimeThemes with their songs and artists, and plays them in mpv, one or all.
    • Discuss an episode: watched episodes link to their discussion on your Kioku server, r/anime and MyAnimeList.
    • News: Home and title pages show headlines from Anime News Network and MyAnimeList that name titles in your library.

    New in 1.19.0

    • Taste: Stats shows the genres, tags, studios and voice actors of what you watch and read, by how often or how well rated, and how your taste moved over the years. Kioku reads the main cast of your anime from AniList slowly in the background.
    • Top charts: the best rated anime, manga and light novels of all time or of a year, in a genre or with a tag, with your status next to each.
    • Season planner: the Seasons page shows your picks for the season and how they went, and how past seasons went.
    • New from your favourites: Home lists the airing and announced works of the staff, voice actors and studios you keep.
    • Birthdays: Home shows the birthdays of your favourite characters and people this week.

    New in 1.18.0

    • Lists from other trackers: import Anime-Planet and Simkl exports, Taiga's anime.xml and CSV files. Kioku finds each title by its IDs, the cross-reference data or an exact title on AniList, shows a preview first and lists the titles it could not find.
    • CSV export: download the whole library as a CSV file that any spreadsheet opens and Kioku reads back.
    • Time machine: Stats shows your library as it was on any day, next to how it is now.
    • Saved searches: save a search with all its filters under a name, and pick up recent searches under the search box.

    New in 1.17.0

    • Scores in detail: score story, characters, visuals, sound and enjoyment from 1 to 10 under a title's score, and take their average as the score. Stats shows your averages.
    • Drop reasons: dropping a title asks why, with a tap for the usual reasons and room for a few words. The reason shows on the title, and Stats adds them up. Settings can turn the question off.
    • Duplicate titles: Settings > Data finds titles that are in your library twice, one work linked on two services or the same title added again, and keeps the one you choose.

    New in 1.16.0

    • Franchises: a title's page shows every season, film, OVA and special of its franchise, grouped, with how many you finished, the episodes watched and the hours left. Add the missing ones with one click. Franchises in the sidebar lists the franchises in your library with how far along you are.
    • Watch order: show a franchise in release order or in watch order, with prequels first and side stories, recaps and spin-offs after what they come from, or only its main story.
    • Gone quiet: Home lists titles you are watching or reading that nobody touched for a month (three for manga and light novels), to pause, drop or leave for later.
    • Calendar: Stats shows your current and longest streak of days with an episode or chapter marked, and a calendar of what you watched and read each day.

    New in 1.15.0

    • Smart lists: save the filters and order of Library, Anime, Manga or Light novels as a smart list and it sits in the sidebar with how many titles it holds now. One click opens it.
    • Rewatch history: a title's page lists each time through it, the first watch and every rewatch, with the days they started and ended.
    • Episode log: a title's page shows when you marked each episode or chapter, and Stats lists the episodes and chapters of each month with the latest ones.
    • Episode notes: give any episode or chapter a note and a rating of one to five stars in the title's episode list.

    New in 1.14.0

    • Advanced search: More filters on the search page narrow by source material, country of origin, and ranges of episodes or chapters, minutes an episode, average score and years. Pick a studio or a person to see their works, narrowed by the other filters.
    • Richer notifications on Windows: episode notifications show the cover and have Watch, Mark watched and Open buttons. Mark watched updates your progress without opening Kioku. On Linux, notifications show the cover too.
    • Notification area icon on Windows: Kioku's icon opens the window or quits Kioku, which helps when Kioku keeps running in the background.

    New in 1.13.0

    For Kioku accounts:

    • Clubs: groups of members around a show, a genre or anything else, each with its own discussion. Public clubs are open to all or take members on request; private clubs are seen only by their members, who invite others. Owners name moderators, and every club shows what its members are watching now.
    • For you: Discover in the web version suggests titles that members with a taste like yours scored highly, and title pages show what the people who liked a title also liked. Nobody's name or library shows, only the titles and how many back them.
    • Recommend to friends: send a title to friends with a short note; they get a notification and, if they like, an email.
    • Hosted watch together rooms: the server runs its own watch together rooms. Signed in to a Kioku account, the app offers them first in Watch together; friends with Syncplay join them too.

    New in 1.12.0

    • More like this: a title's page shows works that share its strongest tags, genres and studio, with what they have in common under each cover. Its own sequels and prequels are left out.
    • Missing episodes: Settings > Player and files tells how many titles miss episodes in your folders and lists them, and a title's page says which aired episodes past where you are have no file yet.
    • For Kioku accounts, in the web version:
      • API tokens: make tokens on the Account page for your own scripts, apps and bots, choosing whether they may read, change your library or post in your name. A token never reaches your password, devices, two-factor sign-in, messages, moderation or administration. docs/server-api.md explains the API.
      • Spam protection: writing where others read asks for a confirmed email address, admins can block words and addresses, and moderators can hide everything a spam account wrote at once.

    New in 1.11.0

    • Episode lists: a title's page lists its episodes with their names, air dates, lengths, stills and summaries (from Kitsu), the exact air time of upcoming ones, and links to stream each episode. Tick episodes off one by one; a tick can be undone.
    • Spoiler shield: names, stills and summaries of episodes past the next one you are due to watch stay hidden until you show them, and tags that give the story away stay folded. It is on by default and can be turned off in Settings.
    • Timeline: Stats has a Timeline view with the anime you watched by year and season, either by when you watched them or by when they aired, with how much time each year took.
    • Arrange Home: every part of Home can be hidden or moved, like the sections of a title's page.

    New in 1.10.0

    More for Kioku accounts, in the web version:

    • Reviews: write a review of a title in your library, with a score, and mark it when it gives the story away so readers open it on purpose. Others vote whether it helped; the most helpful come first. Reviews show on title pages and on profiles, and can be reported.
    • Lists: make lists of titles in your own order with a note on each, and choose who sees them: everyone, members, friends or only you. A public list opens for anyone with its address, no account needed. Add titles to a list from their pages; your lists show on your profile.
    • Admin panel: the server's numbers and storage, a button to update the catalog, people with their roles, extra roles (catalog, translations, achievements) and suspension, and the forum's boards to add, rename, order and remove.

    New in 1.9.0

    Kioku accounts get their own catalog of titles, so a library on the server needs no other service:

    • A catalog of anime from the anime-offline-database: titles in every language they go by, format, episodes, season, status, pictures and tags, with their IDs on AniList, MyAnimeList, Kitsu and AniDB. The server keeps it up to date by itself.
    • Add titles in the web version: search the catalog by any title and add with a status. Every title has a page with its details, your entry, links to the services that know it, and its discussion.
    • Suggest changes: anyone can suggest a correction to a title, or a title the catalog lacks (manga and light novels too). Moderators, admins and people with the catalog role review the suggestions, and you hear whether yours was taken. Changes made this way stay when the catalog updates.
    • Community scores: each title shows how many members keep it and their mean score, once three members scored it. Discover lists each season's anime by how many members keep them or by score, and the best scored titles of all time.

    New in 1.8.0

    The forum arrives on Kioku accounts, in the web version at kioku.toxik.space:

    • Boards for announcements, general talk, recommendations, Kioku itself and everything else, with threads, quotes, edits and a preview of what you write. Posts can use bold, italic, quotes, links, @names and ||spoilers|| that open on a click.
    • Every title has its own page of threads and one thread per episode or chapter. Posts that give away an episode or chapter you have not reached are folded ("Gives away episode 7; you are at episode 5") until you choose to see them. Library entries and activity link to their title's threads.
    • Notifications: replies in threads you posted in, @mentions, quotes, friend requests and replies to your activity show under the bell at the top. Nobody you block reaches you there.
    • Notification emails: once a day by default, soon after something happens, or never (Account). Every email has a link that turns them off.
    • Moderation: report posts, threads, profiles, messages and replies. Moderators work through the reports, hide or lock, mute for a while or suspend, and the person affected is told the reason. Everything moderators do lands in a log.
    • New accounts can post less in their first day, and the same post cannot be sent twice in a row.

    New in 1.7.0

    • Up next: put titles from your library in your own order to watch or read next. They show first on Home with Play, Watch and +1, move earlier or later, and leave by themselves once finished or dropped. Add them from a title's page or from Continue watching.
    • Goals for the year: set how many anime, manga and light novels to finish this year on Home, and see how far you are and whether you keep pace with the year.
    • Time in Planning: Home says how many hours of anime your Planning holds, and the random pick can choose only titles that fit a weekend.
    • A notification when a title in your Planning starts airing, on by default (Settings > Notifications).
    • Messages on Kioku accounts: write to your friends in the web version. Unread messages show in the navigation, read marks show what was seen, and you can remove a message you sent.

    New in 1.6.0

    People on Kioku accounts, in the web version at kioku.toxik.space:

    • Profiles: a picture and a banner (animated GIFs stay animated), a display name, pronouns, a few lines about you, a website, up to 12 favourite titles from your library and numbers per kind (titles, episodes or chapters, completed, mean score). Pictures lose what they carry besides the picture, such as the place a photo was taken.
    • Who sees what: your profile and your library each go to everyone, to people with an account on the server, to your friends only, or only to you. Adult titles show to others only if you allow it; entries you mark private and your notes never do.
    • Friends and following: find people by name, ask them to be friends, follow them without asking, and block anyone, which ends every tie and hides you from them. People shows your friends, requests waiting both ways, who you follow, your followers and who you block.
    • Activity: what you and the people you follow and are friends with watch and read shows on the Activity page and on profiles: episodes watched (a run of episodes is one item), started, completed, paused or dropped titles, and scores. Like them and reply. A first sync of a whole library stays quiet, and private entries never show.
    • Fixed: imports of large uncompressed MyAnimeList files were refused.

    New in 1.5.0

    • Two-factor sign-in for Kioku accounts: turn it on under Account in the web version with an authenticator app (scan the QR code or type the key), and logging in asks for a six-digit code after the password, in the browser and in the app. Ten recovery codes, shown once, get you in without your phone.
    • Your data on the server: Account in the web version downloads everything the server keeps about you as one file, and deletes the account (with your password and your name typed out) for good.
    • Import into a Kioku account: the web version's library takes a MyAnimeList export (.xml or .xml.gz) or a Kioku data download, shows what it would add, replace or keep, and imports it. Titles already in your library stay as they are unless you choose the file's values.
    • Privacy policy and terms of use on the server, in English and Slovak, linked from every page and from sign-up.
    • Paste a link to a title from AniList, MyAnimeList, Kitsu or MangaBaka anywhere in the app (or into Add title) and it opens in the add dialog, one click from your library.
    • Behind on airing: titles you watch while they air show how many aired episodes you have not seen yet ("2 behind") on their covers and rows, the library filters can show only those, and Home links to that list.
    • Fixed: long pages of the web version could not be scrolled with a mouse wheel or a finger.

    New in 1.4.0

    • Kioku accounts: Kioku now has a server of its own, at kioku.toxik.space. Sync > Kioku logs in to an account there, or creates one with an email and an invite code from a friend, and keeps your library on the server in step with the app: every title, the ones you added yourself included. A second computer that logs in gets the whole library, and AniList, MyAnimeList and the rest keep syncing beside it.
    • The web version: the server's address opens Kioku in any browser or phone. Log in to see your library by kind and status, add an episode with one click, change status, score, dates, notes and tags, make invite codes for friends, and see which devices are signed in.
    • Joining is by invite at first: everyone on the server can hand out a few codes, and the people who run it can open sign-up to everyone later.
    • For whoever runs the server: the release carries Kioku-server-1.4.0-linux-x64.tar.gz (and arm64) with the server, a container recipe and podman units for systemd, PostgreSQL included, with nightly database backups. The guide inside walks through it; the first account becomes the admin with the setup code the server prints.

    New in 1.3.2

    • Fixed: on some computers every change in Settings failed with "language lists are codes separated by commas", and notifications could not be turned on. Kioku now resets a stored setting it cannot accept to its default instead of refusing every later change, and accepts audio and subtitle languages written with spaces ("ja, jpn") or with regions such as es-419.

    New in 1.3.1

    • Fixed: on Linux and macOS, stopping Kioku from the terminal it was started in (Ctrl+C) or with a signal left its window open on a page that no longer answered. The window now closes with Kioku.

    New in 1.3.0

    • Your own player counts: Kioku now sees which episode VLC, MPC-HC, MPC-BE, PotPlayer, SMPlayer, KMPlayer, GOM Player, mpv, mpv.net or the Media Player app has open on Windows, and every MPRIS player plus the window titles on Hyprland, Sway and i3 on Linux. It finds the title in your library and marks the next episode watched once most of it played, with Undo in the toast. A bar under the page shows what it recognised; an episode further ahead waits for Mark watched, and a file it cannot place offers Choose title, which Kioku remembers for every file with that name. Turn it off under Settings > Player and files.
    • Play files in your default player: Settings > Player and files > Play files in > Default player opens episodes in whatever program your system opens videos with, so Play works without mpv, and Kioku follows that player as above.
    • The Discord status shows episodes from other players too, with the time left when the player tells it.
    • Home suggests what to watch and read next: Next in the series lists sequels of what you finished that are not in your library yet, and Recommended for you collects what AniList's users recommend next to your best-rated titles. Wave away what you do not want and it stays away.
    • Kioku tells you when a sequel of a title you finished or are watching is announced or comes out (Settings > Notifications > Sequels).
    • Tags: Search can require or leave out any of AniList's tags (Isekai, Time Skip, Female Protagonist and hundreds more), a title's page lists its tags with spoilers hidden until clicked, and the library filters have a Tags section. Kioku reads the full AniList record of every title in your library in the background, so tags, descriptions and related titles are there for lists brought in from elsewhere too.
    • Stats has Your year: titles finished per kind and month, time watched, mean score, top genres, tags and studios, the highest rated and the longest, for any year.
    • Compare with a friend: open someone you follow on AniList under Friends to see your taste match from the scores you both gave, their favourites you have not seen, yours they have not, the titles you both love and where you disagree most.
    • Backups: Kioku now also backs up once a day when the library changed, and Keep copies in (Settings > Data) copies every backup to a folder of your choice, such as one OneDrive, Google Drive or Dropbox keeps safe.
    • Updates list what every release since yours brought, not only the newest.

    New in 1.2.0

    • Characters, staff and studios: three new pages in the sidebar keep your favourite characters, people (voice actors, directors, authors) and studios. Their own pages show who they are, AniList's description with spoilers hidden until clicked, and their works: where a character appears and who voices them, a voice actor's roles and other credits, a studio's works. Press the heart on their pages, in Search or on a title's page; with AniList connected, Import from AniList brings in your favourites from there.
    • Search finds characters, staff and studios too, and Source now lists every service Kioku is set up for: MyAnimeList and AniDB join Kitsu and MangaBaka.
    • Where to watch says where each link works when its address or AniList's note tells (Japan, United States, Southeast Asia and so on) and marks links meant for other regions than the one set in Settings.
    • Images load much faster: a cover Kioku has not kept yet comes straight from its image server, alongside the rest of the page, while Kioku keeps a copy for next time. With nothing kept yet, the first screen of the library loads in under a second instead of three, the seasons page instead of seven.
    • Fixed: MyAnimeList got the same progress on every sync for titles where Kioku counts more episodes or chapters than MyAnimeList's record of the work.
    • Fixed: kioku version prints the version; it used to start the app.

    New in 1.1.1

    • Linux with NVIDIA graphics: Kioku now opens in an app window of Chromium, Chrome, Brave, Vivaldi or Edge when one is installed, instead of WebKitGTK. WebKitGTK crashed on NVIDIA's driver, and drawing without the GPU made it lag; the browser window draws with the GPU, smoothly. KIOKU_WINDOW=native keeps WebKitGTK.
    • When Kioku crashes, the details are written at the end of kioku.log in the data folder (Settings > App shows the folder), so a crash can be reported and fixed. On Linux the system's crash reporter also keeps a core dump.

    New in 1.1.0

    • Kitsu: connect with your Kitsu email or profile name and your password. The password goes to Kitsu once, for a login token, and is not kept. Anime, manga and light novels sync both ways, with Kitsu's scores of 1 to 10 in half steps.
    • MangaBaka: connect with an API key from your MangaBaka account settings. Manga, manhwa, manhua and light novels sync both ways, chapters and volumes included.
    • Search can ask Kitsu or MangaBaka instead of AniList (Source next to the tabs), for the titles AniList does not have, and add them in one click.
    • Titles from Kitsu and MangaBaka join the same works as on AniList and MyAnimeList through the IDs they carry, so nothing shows up twice.
    • Connecting another service never overwrites what it has with empty values: the first time an entry meets a service, a filled-in note, date, score or volume count wins on either side.
    • Login errors say what was wrong: an empty field, or details the service did not accept.

    Download and first start

    System File First start
    Windows 10 and 11 Kioku-1.22.0-windows.zip Unzip it and double-click Kioku.exe. Kioku is not code signed, so Windows may say "Windows protected your PC": click More info, then Run anyway. Kioku adds itself to the Start menu.
    macOS 12 and later Kioku-1.22.0-macos.zip Move Kioku to Applications and open it. It is not notarized, so the first time open System Settings > Privacy & Security and click Open Anyway.
    Linux x64 and arm64 Kioku-1.22.0-linux-x64.tar.gz, Kioku-1.22.0-linux-arm64.tar.gz Extract and run ./kioku. Kioku adds itself to the application menu.

    SHA256SUMS lists the checksums of every file. Kioku opens in a window of its own (WebView2 on Windows; on Linux WebKitGTK, or a Chromium-based browser's app window with NVIDIA graphics or without WebKitGTK; the default browser as a last resort). To connect AniList, open Sync, choose Connect next to AniList and approve: nothing else to set up. The first sync is always a preview that changes nothing until you apply it.

    To play episodes in Kioku's own player, install mpv; or keep the player you have and let Kioku follow it. Everything else Kioku needs comes with it or installs itself.

    What Kioku does

    Home and your library

    • Home shows what to watch and read next: your own Up next list, the next episode or chapter of everything in progress, with Play or Read when the file is on your computer and Watch on your streaming service otherwise, what airs this week from your list, first episodes further out, sequels of what you finished, recommendations from your best-rated titles, a random pick from Planning (only what fits a weekend if you like), the next English volumes of what you read, goals for the year, news about your titles, titles that went quiet, and finished titles still waiting for a score. Arrange sections hides and orders them.
    • Library, Anime, Manga and Light novels show your entries as covers, a list or a table, with status tabs, filters (format, genre, tag, year, season, score, provider links, airing, behind on airing, my streaming services), saved presets and sorting; presets can sit in the sidebar as smart lists with live counts. Franchises groups the seasons, films and OVAs in your library with combined progress. Airing titles show how many aired episodes you have not watched yet.
    • Quick edits everywhere: +1, status and score menus, a full editor with a date picker for started and finished dates, a tag picker and scores in detail. Dropping a title asks why, if you like. Your own tags can be renamed, merged, coloured and deleted in Settings.
    • Select several titles to change their status, score or tags, put them on a list or remove them at once; removing asks first and can be undone.
    • The keyboard works throughout: Ctrl+K opens the command palette, / filters, j and k move, + and - change progress, 1 to 9 score, ? lists the keys.
    • Titles of your own that no provider knows can be added by hand.
    • Paste a link to a title on AniList, MyAnimeList, Kitsu or MangaBaka anywhere to open it in Add title.

    Finding titles

    • Search covers all of AniList's anime, manga and light novels: type a name or browse what is trending, with filters for format, status, season, year, genres, tags, source material, country, episodes, length, score and years, a studio's or a person's works, and five ways to sort; save searches with their filters, and recent ones wait under the search box. Top charts rank the best rated by year, genre or tag. Characters, Staff and Studios search AniList's people. Source switches to another service Kioku is set up for (MyAnimeList, AniDB, Kitsu, MangaBaka), searched by title. One click adds a title.
    • A title's page has your entry, where to watch, the airing schedule, its episodes to tick off one by one with a note and a rating each and the day each was watched, every time you watched it, its whole franchise in release or watch order, its tags, characters with their voice actors, staff, recommendations, more like it, related titles, the trailer, its openings and endings to play, its English volumes, and news that names it, plus what your friends think of it. Watched episodes link to their discussions. Arrange sections chooses what shows and in what order. The spoiler shield keeps the names, stills and summaries of later episodes hidden until you show them.

    Syncing

    • Two-way sync with AniList, MyAnimeList, AniDB, Kitsu and MangaBaka, field by field against what each service last confirmed, so changes on both sides merge instead of overwriting each other.
    • Every first sync is a preview. Conflicts wait for you to choose, and nothing is ever deleted on a service without your confirmation.
    • MyAnimeList XML exports can be imported without an account, and the library exported in that format. Anime-Planet, Simkl, Taiga and CSV lists import too, and the library exports as CSV.
    • Titles are linked across services with the anime-offline-database, the IDs Kitsu and MangaBaka give, and title matching; uncertain links wait for review.

    Watching

    • Add the folders with your episodes in Settings > Player and files. Kioku reads the file names, links the files to your titles and lists them on each title's page; files it cannot place wait for you to assign, and aired episodes with no file are listed.
    • Episodes play in mpv with the following ones queued, resume where you stopped, are marked watched near their end, and openings and endings are skipped from chapters and AniSkip, on their own or with Tab. A bar under every page shows what plays and controls it.
    • Or watch in the player you like: Kioku follows VLC, MPC-HC, PotPlayer and the others, and Play can open files there.
    • Free official streams (YouTube, Bilibili) and trailers play in mpv through yt-dlp, which Kioku installs, checks and keeps up to date along with Deno.
    • Where to watch lists the streaming services of each title, your services first, with the region a link is meant for when Kioku can tell and the services it came to or left lately; Watch opens the episode and Kioku offers to mark it watched when you come back.
    • Discord can show what you watch as your status (Settings > Player and files). It needs a Discord application ID, which Settings explains how to make.

    Reading

    • Manga, comics and light novels in the same folders open in Kioku's reader: CBZ, ZIP, CBR and RAR archives, folders of images, PDFs and EPUBs.
    • Right to left, left to right, two pages at a time or a long strip, remembered per title; EPUBs follow the app's colours with a text size of your choice.
    • Kioku remembers the page, counts a chapter or volume as read at its end and offers the next one.

    Together with friends

    • Watch together puts you and your friends in a room on a Syncplay server, or on your Kioku server's own rooms: pause, seek and the next episode happen for everyone, with a chat. An invite link opens the room in a friend's Kioku; friends with Syncplay itself can join too.
    • Friends shows the people you follow on AniList and what they watched and read lately, and compares your tastes with any of them.
    • Lists are your own lists of any titles, in your order with a note each. Share a list or a single title as a link that opens in a friend's Kioku, as text with AniList pages, or as a file. Your friend sees a preview and keeps it as a list, adds the titles to their library or picks single ones.

    Characters, staff and studios

    • Characters, Staff and Studios keep the ones you like, with their pictures, newest first; AniList favourites can be imported. Home shows their new works and birthdays.
    • Their pages come from AniList: details, description, and the works they are part of, with voice actors, voice roles and credits; every work opens or goes to Planning with one click.

    Seasons, schedule, notifications and stats

    • Seasons shows each anime season with countdowns, streaming services and one-click adding, plus the shows still airing and the announced ones, and how your picks for each season went, plus a reel of the season's trailers.
    • Schedule is the week's airing timetable in your time zone. Its calendar feed brings the episodes from your list into calendar apps, or into a file for web calendars.
    • Notifications when new episodes air (or their dubs, for titles you watch dubbed), when a planned title starts, when sequels are announced, when new chapters of what you read are out and when a title comes to or leaves your streaming services, plus a weekly recap: in the app, on the desktop (with the cover and, on Windows, Watch, Mark watched and Open buttons), through Web Push, ntfy, Gotify, Discord webhooks or any webhook, with a delay after broadcast, quiet hours, a daily digest, per-title settings and snoozing.
    • Stats sums up time watched, chapters read, scores, genres and your activity, lists the episodes and chapters you marked month by month and day by day with your streaks, the Time machine shows the library on any day, Taste shows the genres, tags, studios and voice actors you like, Your year looks back at any year, and the Timeline lays out your anime by year and season.

    Your data

    • Kioku backs up the library before every sync or import that changes it and once a day when it changed, keeps the last ten, and can copy each one to a folder of your choice. Settings > Data lists them and restores one (Kioku backs up the current state first and restarts with the backup).
    • Settings > Data finds titles that are in the library twice.
    • Moving to another computer: restore a backup file from the old computer, or export the library file there and import it on the new one.
    • Logins and passwords are kept in the system keychain (Windows Credential Manager, macOS Keychain, Secret Service on Linux), never in the database.

    Kioku accounts

    • An account on kioku.toxik.space keeps your library on the server, synced with the app on every computer you log in from and open in any browser or phone.
    • Sign-up is by invite code; members hand out codes to friends.
    • Two-factor sign-in with an authenticator app and recovery codes; a list of signed-in devices, each of which you can sign out.
    • Import a MyAnimeList export or a Kioku data download into the account, download everything the server keeps about you, or delete the account. The privacy policy says what is kept and for how long.
    • Profiles with a picture, banner, favourites and numbers; your profile and library shown to everyone, members, friends or only you.
    • Friends, following and blocking, an activity feed of what friends and followed people watch and read, with likes and replies, and messages between friends.
    • A forum with boards, threads per title and per episode with spoilers folded for whoever is behind, notifications with optional emails, and moderation with reports.
    • A catalog of anime to add titles from without any other service, suggestions to improve it, community scores and Discover by season.
    • Reviews with helpful votes, lists of titles to share, and an admin panel for whoever runs the server.
    • API tokens for your own scripts and bots, and spam protection with blocked words and confirmed addresses.
    • Clubs with their own discussions, recommendations from members with a similar taste, titles recommended to friends, and watch together rooms on the server.

    Look and feel

    • Light and dark themes, an interface colour of your choice (a preset, any colour, or one taken from a picture), with light and dark versions worked out so text stays readable.
    • English and Slovak.
    • A native window without browser menus, and every page works at phone width.
    • Kioku checks for new releases twice a day; on Windows and Linux it installs them (checked against the published checksums) and restarts into them.

    As a server

    kioku serve runs Kioku without a window, for a home server or a NAS. It can be reached from other devices with a password set (kioku hash-password). The read-me covers the configuration.

    Good to know

    • Following other players reads window titles on your computer only. On macOS Kioku cannot see other players.
    • MyAnimeList and AniDB let apps in only with a client registration you make yourself; Sync walks you through it. AniList and Kitsu work right away, MangaBaka with an API key you create on its site.
    • AniDB's protocol sends your password unencrypted; Kioku warns before you turn on what needs it.
    • AniList logins return to http://127.0.0.1:7777. If another program uses that port, Kioku moves to a free one and says so; close the other program before connecting AniList.
    • macOS cannot install updates by itself: Kioku links to the download.
