This is an optional browser experiment using a small English speech model. It is separate from the iPhone app, and its speed and accuracy depend on your browser and device. The model runs in a background worker in this tab. There is no server transcription request.

Only press Record when you are ready. Recording stops after 15 seconds or when this tab is hidden. Clear recording closes the model and removes the recording from the page; model files may remain in your browser’s cache.

Trunk on iPhone uses its own recording and transcription system. Read the product’s privacy promise.

Built with Transformers.js, Whisper Tiny English and ONNX Runtime. Model and runtime notices.
