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.
