AITranscribe turns video and audio into text transcripts and timed subtitle files, built around speech recognition rather than existing captions. Paste a public link from Facebook, Instagram or Twitter/X, or upload a recording in MP4, MOV, M4A, MP3, WAV or WebM, then choose an engine: in-browser Whisper runs entirely in your browser for privacy, while Workers AI handles server-side processing. The transcript comes with millisecond timestamps, and one click copies the text or downloads TXT, SRT or VTT files for editors like CapCut and Adobe Premiere or HTML5 video players. The underlying Whisper model supports 98 languages with automatic language detection, and the preview engine is optimized for recordings up to 30 minutes, with longer audio best split into chapters. Files and transcripts are not stored: browser processing stays in memory, and server audio is streamed and purged. A free tier is available after sign-in. It suits creators captioning Reels and short clips, students turning lectures into notes, and editors who need a clean, timestamped transcript without uploading sensitive recordings to a server.
