About Shogi Vault - Shogi Study
Shogi Vault is a shogi (Japanese chess) study app for reviewing your games and building opening research with an on-device AI engine.
Note: the app's interface is in Japanese.
- AI game analysis
Import your games and analyze every move. Good moves, dubious moves and blunders are marked automatically on the move tree and the evaluation graph.
- Fully on-device AI
The YaneuraOu engine with the Suisho5 evaluation runs on your device. No network connection is needed, and positions and games are never sent out for analysis. Pro users can switch to stronger evaluation functions.
- Variation tree
Record unlimited variations from any position, compare them, add comments and pick up your research where you left off.
- Import and export
Supports KIF, KI2, CSA and SFEN, including games with variations. Imported games are sorted into folders by opening automatically.
- Tsume shogi and endgame study
Analyze tsume and hisshi problems with the on-device engine.
- Optional account sync
Sign in with Apple or email to sync settings, research and games across devices. Without signing in, all data stays on your device.
- Privacy
Only when you sign in, your email address and research/game data are stored on the server for syncing. The ad network may collect data for the rewarded ads in the AI battle screen. Usage and crash information is sent to improve the app (game and research contents are not sent; you can turn this off in Settings).
- Open-source engine
The bundled shogi engines are licensed under GPLv3. The corresponding source code of the engine integration is available at:
https://github.com/irep-takeshi-maya/shogi-vault-gpl-source
- Pro plan (auto-renewable subscription)
Monthly and yearly auto-renewable subscriptions and a one-time purchase are available. Prices are shown in the app. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and are charged to your Apple ID account. You can cancel from your Apple ID subscription settings.
