How do I transcribe an iPhone Voice Memo?
Pepys converts M4A to text by transcribing the recording with AI. Drop in any .m4a file – an iPhone Voice Memo, a Mac recording, an exported call – and you get a clean, timestamped, speaker-labeled transcript in minutes, in 99+ languages, with AI summaries built in. No conversion needed. Your first 60 minutes are free, no card.
How m4a to text works
Upload your .m4a file
Drop in a Voice Memo or any .m4a recording – straight from your iPhone, Mac, or files. No converting first.
Get your transcript
AI transcribes it into clean, speaker-labeled text with timestamps, ready in minutes.
Edit and export
Fix anything inline, then export to TXT, Markdown, DOCX, PDF, SRT, or VTT.
M4A is the format your iPhone hands you. Open Voice Memos, hit record on an interview, a lecture, a quick idea, or a meeting, and what comes out is a .m4a file – which most transcribers choke on or force you to convert first. Pepys reads it natively: drop the file in and get back a clean, accurate transcript you can search, quote, and reuse.
Every transcript comes speaker-labeled and timestamped, with AI summaries and chapters built in – so a 40-minute memo becomes notes you can actually skim. We never train on your audio, and you pay only for what you transcribe; credits never expire.
Clean paragraphs. No more um's and ah's.
The left is what Pepys hands back – logical paragraphs with the filler stripped out, punctuated and readable. The right is the raw, one-line-per-segment dump most transcribers leave you with.
um so yeah everyone keeps telling you to like lead with your best line right but uh honestly if you give away the whole answer in the first second you know there's basically no reason for anyone to keep watching so the hook isn't kind of the smartest thing you say it's like a loop you open that they need to close and um that's the part that actually keeps people around
RawReads .m4a natively – no converting Voice Memos to MP3 first
Speaker labels and timestamps on every transcript
AI summaries, chapters, and chat built in – not a separate ChatGPT trip

M4a to text – questions, answered
How do I transcribe an iPhone Voice Memo?
Share the memo to your computer or save it to Files, then upload the .m4a here. Your first 60 minutes are free, no card – you'll get a clean, timestamped transcript in minutes that you can edit and export.
Do I need to convert the .m4a to MP3 first?
No. Pepys reads .m4a (and the AAC audio inside it) directly, so you skip the conversion step entirely. Just upload the file as-is.
Is the transcript accurate?
Yes – Pepys uses top speech-to-text models with automatic language detection, speaker labels, and timestamps. You can edit anything inline before exporting.
Do you train on my recordings?
Never. We don't train AI on your audio or transcripts, and you can auto-delete your files after processing.
What can I export?
TXT, DOCX, SRT, and VTT – with correct timestamps for subtitles.
