Linberry
Linberry is a personal AI language tutor that captures useful words, phrases, idioms, and grammar points from your conversations and saves them to a private dictionary on your device. You can turn those saved points into interactive Quest games, spoken podcast review episodes, and quizzes. It can also read target-language web pages, explain text from photos, and help with pronunciation.

AI and local access
- Linberry uses the AI providers and models you have configured in AppJuice for chat, web reading, image understanding, image generation, speech-to-text, and text-to-speech.
- These features only run when you ask for them and are focused on language learning.
- Your dictionary, settings, review progress, and generated podcast audio are stored locally on your device.
- Linberry may ask for access to local files or tasks only when needed, and AppJuice will ask before sensitive access.
Safety and privacy
- Your learning data stays on your device, and you can edit or delete any saved item at any time.
- The app passed AppJuice safety checks for sharing.
- No hidden or unnecessary device access was found.
- Internet features are limited to the language-learning actions you request.
Good to know
- Linberry is designed for language learning; off-topic requests are politely redirected.
- AI-generated content may occasionally contain errors; use it as a study aid, not the only source of truth.
- To start, simply ask the tutor about a word or phrase in your target language. It will begin saving useful points automatically.
- For interactive practice, open Quest from the top bar or ask the tutor to start a specific game.
- Linberry is available as a desktop AppJuice app; some features may not work in a browser-only environment.
