About the speech-to-text tool
A free speech-to-text tool that transcribes audio and video locally in your browser, powered by a Whisper model running on your device. It is intended for meetings, interviews, lectures, podcasts, and voice memos — including sensitive recordings that should not be uploaded to a cloud transcription service.
How it works
Audio is decoded in the browser with the Web Audio API, then a Whisper model (transformer-based speech recognition) runs through Transformers.js. On WebGPU-enabled Chrome or Edge the model executes on your GPU and a one-hour file transcribes in a fraction of real time; on other browsers a WebAssembly path keeps the same features available. The model files download once and are cached, so you can transcribe offline afterward. Finished transcripts can be copied as plain text or exported with timestamps.
Limits & requirements
The browser ships the lightweight Whisper tier for fast, free inference; it is excellent for clear speech but less forgiving on heavy accents or noisy multi-speaker recordings than paid large-model APIs. Long multi-hour files may hit browser memory limits on low-RAM devices; splitting long recordings is the workaround.
Privacy
This is the key difference from cloud services: your recordings are never uploaded. Interviews, confidential calls, and personal memos are processed and stay on your machine, with no per-minute billing.
