Subtitle Studio transcribes English audio and video (MP3, WAV, M4A, OGG, FLAC, WebM, MP4, MOV) into timed captions with Whisper running in your browser, then lets you edit, split, merge, retime and re-wrap them. It exports SRT, WebVTT, plain text or JSON, and the media never leaves the browser.
Whisper downloads once, then transcribes on this device.
Click a row to jump the player there. Edit the text in place, retype a time as mm:ss.mmm, or put the cursor where a caption should break and press Split. Undo (Ctrl+Z) takes back a split, merge, deletion or retiming.
SRT suits most video editors and YouTube, WebVTT the web, JSON keeps the exact timings.
