Transcribe audio to text with AI

Select an audio file (MP3, WAV, M4A, OGG, FLAC or WebM) and get the text of the speech on screen, to copy and use wherever you like. The transcription is done by AI (Whisper), and the text appears as the processing advances. It works for interviews, classes, voice notes and notes.

Tips for a good result

  • Cleaner audio, with the person close to the microphone, gives a more faithful text.
  • If the audio mixes languages, use “Detect automatically”.
  • To turn the speech into timed subtitles, send the result to WebFaz Subtitles with the “Send to” button.

What this tool does not do

  • Transcription needs the internet: the audio is sent to an AI service (Groq) to be processed. WebFaz does not store the audio.
  • The limit is 30 minutes of audio per upload and 30 minutes per day in this browser; the app shows how much is left.
  • The AI can make mistakes with names, numbers and technical terms, and recordings with noise or overlapping voices worsen the result: review the text.
  • The result appears only on screen: the app does not download a text file. Use Copy.
  • The text comes out running together, without separating who is speaking.
