Free audio and video transcription that never uploads your file. Turn an MP3, M4A, WAV or video file into editable text and SRT or VTT subtitles. OpenAI’s Whisper model runs in your browser, so the file is never uploaded. Free, no sign-up, no minute limits. Files up to 60 minutes and 300 MB, English or 99 languages, and each subtitle gets real start and end times.
