# FAQ

#### General

**Q: Is my voice data sent to the cloud?** A: No. Voice recording and transcription happen entirely offline using Vosk. Only the transcribed *text* is sent to OpenRouter's AI for processing.

**Q: Can I use Pebbl without internet?** A: Partially. You can record and transcribe offline, but AI features (follow-up questions, drafts, lecture analysis) require internet.

**Q: What languages are supported?** A: Currently English only. Other languages can be added by downloading corresponding Vosk models.

**Q: How much does it cost to use?** A: The app is free. However, you need an OpenRouter API key which has usage-based pricing. Gemini 2.5 Flash Lite is very affordable (\~$0.01-0.10 per session).

#### Features

**Q: Can I edit transcriptions?** A: Not currently. This is a planned feature. For now, speak clearly to improve transcription accuracy.

**Q: How do I link lectures to projects?** A: This feature is implemented in the database but not yet in the UI. Coming soon!

**Q: Can I export drafts to Google Docs?** A: Not yet. Current export options are clipboard copy and sharing to other apps. Direct Google Docs integration is planned.

**Q: Is there a web version?** A: No, Pebbl is Android-only. A web version may be considered in the future.

#### Technical

**Q: Why Room instead of Firebase?** A: Room provides offline-first data persistence, better privacy (data never leaves device), and faster queries for local data.

**Q: Can I change the AI model?** A: Yes, edit `AiRepository.kt` and change the `model` constant to any OpenRouter-supported model.

**Q: How do I add more pebble types?** A: Edit `PebbleType.kt` enum and add new entries with color, name, description, and unlock logic.

**Q: Is this app open source?** A: Check the repository for license information.
