Frequently asked questions
How accurate is M4A transcription?
Accuracy depends mainly on recording quality, background noise, and the number of speakers. Clear speech transcribes very well. Test with your own recording on the free plan — no credit card is required.
How do I get a Voice Memo off my iPhone to transcribe it?
Open Voice Memos, tap the recording, tap the share icon, and send it via AirDrop, email, Files, or a cloud drive — or skip the transfer entirely and upload it from Safari on the phone. The .m4a file uploads as is, no conversion needed.
Can I get the M4A transcript as a Word document, PDF, or JSON?
Yes. Every transcription exports as DOCX (opens in Microsoft Word and Google Docs), PDF for polished sharing, plain TXT, and structured JSON with timestamps and speaker labels for developers — plus SRT and VTT subtitles. All formats come from the same upload, so you never re-transcribe.
Can I try it for free?
Yes. The free plan lets you transcribe a real M4A recording each month with no credit card, so you can judge the accuracy on your own audio before paying.
Are my files kept private?
Yes. Files are processed securely, are never used to train AI models, and can be deleted from your account at any time.
