About this tool
Add an MP3, M4A, WAV, OGG or OPUS file, such as a WhatsApp voice note, a recorded call, an interview or a class, and get the full transcript with timestamps, a short summary and key points. Correct any name or word right in the transcript, then download it as a PDF, a Word file or plain text.
Speech is turned into text on your own device with the same Whisper model used by many transcription apps, so private recordings never leave your phone or computer. Hindi, English, Marathi, Bengali, Gujarati, Punjabi, Tamil, Telugu, Kannada, Malayalam and Urdu work, and you can translate any of them to English.
