Speech to Text (In-Browser AI)
AIRuns On Your DeviceTranscribe microphone audio or audio files to text in English, Spanish, French, Portuguese, or Japanese — AI that runs in your browser, no uploads.
First use downloads a compact speech model, cached afterwards for offline use. Your audio is never uploaded to any server.
Free Private Speech-to-Text — AI That Runs on Your Device
Transcribe recordings or live microphone audio with a modern speech-recognition model that runs entirely inside your browser using WebGPU (with a WASM fallback). Unlike online transcription services, your audio is never uploaded anywhere — the model weights are downloaded once, cached locally, and the transcription itself happens on your device.
Five languages are supported: English (Moonshine Base), plus Spanish, French, Portuguese, and Japanese via a compact multilingual model (Whisper Tiny). The first use downloads a ~40–90 MB model — after that, it works offline. A genuine alternative to subscription transcription tools for interviews, voice memos, and dictation, especially for anything you would rather not hand to a cloud service.
