How It Works
Powered by OpenAI's Whisper model running locally via WebAssembly, this tool transcribes spoken audio into text with high accuracy. The AI model loads once and processes your audio entirely on your device — no data is sent to any server.
Upload an audio or video file, select the language (or let it auto-detect), and receive a timestamped transcript. Export as plain text, SRT subtitles, or VTT format for video captioning.
