Frequently Asked Questions
What is Thoughts?
Thoughts is a free, minimal Android app for quickly capturing ideas by voice or text. It uses on-device Whisper AI for voice transcription, so your data never leaves your phone. No accounts, no cloud, no distractions.
How does voice transcription work without the cloud?
Thoughts uses OpenAI's Whisper speech recognition model running entirely on your device. You download a model once (75 MB to 1.6 GB depending on accuracy needs), and all transcription happens locally. No internet connection is required after the initial model download.
Is Thoughts really free? What's the catch?
Thoughts is completely free with no ads, no in-app purchases, and no accounts. There is no catch. It's built by A1Lab as a simple, privacy-respecting utility for capturing fleeting ideas.
What Whisper model size should I choose?
For most users, the Tiny (75 MB) or Base (142 MB) model is fast and accurate enough for everyday notes. The Small (466 MB) model offers better accuracy for longer recordings. Medium and Large models provide the highest accuracy but require more storage and processing power.
