Audio to text converter

Transcribe files or microphone recordings on your device with a local Whisper model, then edit lines and export TXT, SRT, VTT, JSON, or MD.

What leaves your browser

When the browser recognizes speech, your voice goes to the browser maker's speech service, which this page never sees; the decoding, splitting, editing, and exports all stay in this tab. This page leaves your browser only when you press the button; never on load, never in the background. Nothing is sent anywhere else. Google Analytics still measures the visit to this page, and it never receives what you run through this tool.

This tool does not run a Whisper model and does not take podcast links or RSS feeds; recognition is the browser's own speech service where it exists, and without it you still get timestamped segment lines to fill in by hand. Uploads stay minutes-long takes, not 500 MB drops, and nothing is stored after you leave the page. Songs and lyrics transcribe poorly; the segmenter follows loudness, so a paused, quiet take needs the silence gate lowered.

Takes run up to 15 minutes and are decoded to 16 kHz mono in this tab. Boundaries change on the next transcribe, not while these are moved.
