Voice memo to text — free, unlimited, no signup
Drop the M4A from your iPhone's Voice Memos (or any recorder app) and get clean text with timestamps and summaries. No 5-minute caps, no 3-files-a-day quotas — it runs in your browser, so there's nothing to meter.
Voice memos up to 1 hour transcribe as-is (M4A). Longer than an hour? Rare for memos — but if you have one, export it as WAV, which has no length limit.
Why voice memo tools nickel-and-dime you — and this one can't
Every "free voice memo transcriber" that runs on a server pays per minute of your audio, so the free tier is bait: a few minutes per file, a few files a day, then the paywall. Record to Notes transcribes on your own device instead. There's no per-minute bill, so there's no meter — a week of memos costs the same as one: nothing.
| Tool | Free limits | Signup |
|---|---|---|
| Record to Notes | No file cap, no daily cap (M4A ≤1h each; WAV unlimited) | No |
| AudioScribe | Memos up to ~5 minutes | No |
| Meowtxt | First ~10 minutes free | Yes |
| Videotowords | ~3 files per day | Yes |
| Notta | Monthly minute quota, short per-file caps | Yes |
Limits as of September 2026 — plans change, check each site. The structure doesn't: server-side tools meter because they pay per minute; on-device tools don't have to.
From your phone to text, step by step
- iPhone: open Voice Memos → tap the memo → share → AirDrop it to your Mac, or save to Files/iCloud and grab it on any computer. The file is M4A — drop it in as-is, no conversion needed.
- Android: most recorder apps save M4A or MP3. Share the file to your computer (Drive, email, cable) and drop it in.
- Then: text streams in live with timestamps. Long memos get auto-detected chapters with summaries — a rambling 40-minute idea dump comes back with its own table of contents. Export TXT or Markdown for your notes app, and every line keeps its timestamp so you can jump back to the audio.
Worth saying plainly: this runs in a desktop browser, not as a phone app. The workflow is record on the phone, transcribe on the computer — thirty seconds of AirDrop, then everything else is automatic.
Private by architecture, not by promise
Voice memos are the most personal audio there is — half-formed ideas, meetings, things you said out loud to remember. Here, they're transcribed by a speech model running inside your browser (the same open-source Whisper models behind our Whisper online page), and after the model downloads, transcription makes zero network calls. Your memo never uploads anywhere — you can watch the network tab to confirm it, or switch off Wi-Fi and it keeps going.

FAQ
Do iPhone voice memos work directly?
Yes. Voice Memos saves M4A, which transcribes as-is up to 1 hour per file — no conversion step. AirDrop the memo to your computer and drop it in.
Is it really free? Where's the catch?
Transcription runs on your own device, so our costs don't grow with your usage — there's no meter to protect. The paid Pro tier sells cloud speed, top accuracy and batch processing, not permission to use the free plan.
Is my memo uploaded anywhere?
No. Processing happens in your browser with zero network calls during transcription — verifiable in the network tab. On the free plan the audio never leaves your computer.
How long can a memo be?
M4A and MP3: up to 1 hour per file for now. WAV: unlimited. Memos over an hour are rare — if you have one, export or convert it to WAV and it will run.
Can I transcribe on my phone?
It's built for desktop browsers — transcription wants more memory and compute than phone browsers give a tab. Record on the phone, transcribe on the computer.
What do I get besides plain text?
Timestamps throughout, auto-detected chapters with a summary per chapter on longer memos, and TXT/SRT/Markdown export that pastes cleanly into Notion, Obsidian or Docs.
Does it handle other recordings too?
Yes — the same tool handles interviews, lectures and podcasts. See audio to notes for the general case or lecture to notes for classes.
