Turning a voice memo into text
M4A is what iPhone Voice Memos and a lot of recorders produce, which makes this a common way to get a meeting, interview or quick note into writing. Your file is transcribed with Whisper, the open-source speech model, running on our own servers rather than a third-party API: voice activity detection trims silence so the output stays clean.
What it's best for
Single-speaker recordings, a memo, dictation, a lecture: transcribe cleanly, and a clear recording with minimal background noise always reads better than a long, echoey room.
More than one voice?
To label who said what, use Audio to text and the TranscriptAI workspace, which add speaker diarization and timestamps, then you can summarize it, pull action items or build notes from the transcript.

Common questions
Is it free?+
Yes. Convert M4A to Text free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my recording private?+
Uploads go to a private bucket, are transcribed on our own engine, and auto-delete after 1 hour. Files never go to an outside transcription service.
How accurate is it?+
We use Whisper's small model with voice activity detection: strong accuracy across accents, and clean handling of pauses and silence.
