Kaeri knows where you stopped.

Apps for Mac, iPhone, iPad, Android, Android TV, Windows and Linux, and one for the terminal.

The Mac app on Home: the show in progress in the spotlight, the rows rolling up, then a show picked from a row and its title page opening — The Mac app.

Search and the calendar.

Browse by genre, year and season without an account, or follow the seasonal charts and the week’s calendar. A ~ marks an estimated air time, and a Dub tag marks an episode already dubbed.

The Mac app’s search, with a query, its two results and the filters panel open: genres, tags, years and length — The Mac app and the iPhone app.

The iPhone app’s calendar: the week’s days, then each day’s episodes with their times — The Mac app and the iPhone app.

Upscaled as it plays.

Episodes play in mpv, upscaled by ArtCNN or Anime4K, with the opening and ending marked on the seek bar. Drag the line to compare a 480p stream.

Finds the opening by itself.

When AniSkip has no times for an episode, Kaeri compares its audio with the show’s earlier episodes on your device and finds the opening and ending. Found times get the Skip button, and once you confirm them or skip them twice, they skip by themselves like any others. Finding pauses in power saving mode and when storage runs low.

Close up of the Android TV app’s player: Hoshikuzu no Tabibito, episode 7, with the opening marked on the seek bar, and a panel with its start at 1:31, its end at 3:00 and the line Kaeri found these times from the audio — The Android TV app, checking the edges of an opening it found. If you share skip times with AniSkip, Kaeri asks once per show whether the edges were right.

Watch together, and talk.

Start a party and send the link. Everyone’s player stays in step, with chat and reactions in the room. Each person plays from their own sources, and the party runs on a Syncplay server you choose.

The Android app playing an episode in a watch party: Mika’s chat line in the corner, the four reaction buttons down the side, your own laugh, and a man in a suit with his name card — The Android app in a watch party. The picture is from こうしす！ #3.1 by OPAP-JP contributors, CC BY 4.0.

Sync without an account.

Pair your devices on the same Wi-Fi, or add a cloud folder you already use, and your history, resume points and lists stay the same on each. Changes are sealed so only your devices can read them, and Kaeri runs no server for it. Your trackers still get each change in order, even after a week offline.

Close up of the Mac app’s Devices settings: Kim’s iPhone, Living room TV and Kitchen iPad under Your devices, a sync note, a Google Drive cloud folder and the recovery key — The Mac app’s Devices settings. A cloud folder can be in Dropbox, OneDrive, Nextcloud, a WebDAV server or a folder on the device, and in Google Drive on Apple devices and Android phones and tablets.

Your phone is the TV remote.

Send an episode to the Android TV app, then pause, seek and switch subtitles from your phone. The Mac, iPhone, iPad, Android, Windows and Linux apps all work as the remote.

The iPhone app as the TV’s remote: the episode playing, play and seek buttons, subtitles, audio and the TV’s volume — The iPhone app as the remote, and the Android TV app.

The Android TV app on a title page, with a button to resume episode 7 and the episode list — The iPhone app as the remote, and the Android TV app.

You choose the sources.

Sources are plugins, and each one can reach only the hosts it lists. Run a store for your own plugins and your own devices. Every device you add gets a token of its own.
