Kioku
The real Anki desktop app on your phone, in your browser and on your own server.
Add-ons, the card browser and every desktop feature, made for a touch screen.
User manual · Releases · Screenshots · Issues
AnkiDroid and AnkiMobile are great, but some things exist only in Anki
desktop: add-ons, and the desktop's own card browser, editors and tools.
Kioku runs the unmodified Anki desktop app (aqt, Qt 6, Anki's Rust
core) wherever you are: as an app on your phone, in a browser tab, or on
your own server, used from any browser. (Kioku, 記憶, is Japanese for
"memory".)
Pick a variant
| Needs | Feels like | Your collection | Install | |
|---|---|---|---|---|
| iPhone, iPad | iOS 17+ (39 MB) | a phone app | on the device | TestFlight, AltStore or sideload |
| Android, native | Android 9+, arm64 (48 MB) | a phone app | on the device | APK |
| Android, Termux | Android 7+, arm64, ~1 GB free, 3 GB+ RAM (235 MB) | a small Linux desktop | on the device | APK |
| Web (experimental) | a recent browser (~31 MB download) | Anki in a tab | in that browser | open it |
| Your server (Docker) | amd64 or arm64 server, any browser | Anki desktop, streamed | on your server | compose file |
All of them are the same Anki release and sync with each other through AnkiWeb or a sync server. Not sure? See Which variant?

Features
- Anki desktop, unmodified: Anki 26.09.3's own Python code and Rust core, with a thin layer that fits it to a phone.
- Desktop add-ons from AnkiWeb, installed inside the app.
- Made for touch: big type, drag to scroll, the keyboard opens on text fields, windows fit the phone in portrait and landscape.
- Your data stays with you: on the phone, in your browser or on your server. AnkiWeb sync, import and export work as usual.
- The phone as a sync server for AnkiDroid, Kioku and Anki on your computers, and AnkiDroid's media folder shared with a Kioku profile (Android).
- Remote desktop: the phone's Anki in a computer's browser (Termux).
- Self-hosting: a Docker image runs Anki desktop on your server or NAS, with your add-ons and a large collection, and streams it to any browser.
How to install and use it: the Kioku manual (source in docs/manual/). Everything about Anki itself is in Anki's manual.

The Anki version for every variant is set in
shared/versions.env. GitHub Actions build the apps
on a v* tag and attach them to the release; the Docker image is built,
tested and pushed to ghcr.io/krmanik/kioku-desktop on a release.
