Free Voice to Text Online — Audio File Transcription, No Install
You recorded a voice memo. A meeting. A lecture. A podcast clip. You need the words as text — for notes, for sharing, for editing — and you need it in five minutes, not five hours.
AI Pass Voicenote does it in seconds. Drop the audio, get the transcript, copy the text. Free to start.
The 30-second flow
- Open aipass.one/apps/voicenote
- Drag your audio file in (mp3, m4a, wav, ogg, webm — most formats work)
- Click Transcribe
- Wait — usually under a minute for short clips
- Copy the result, or download as a text file. Try it now.
The transcript handles punctuation, paragraph breaks, and typically multiple speakers without you needing to label them.
Why it's actually free
Sign up = $1 credit in your wallet. Transcription is billed per minute of audio — typically a small fraction of a cent per minute. A dollar covers hours of audio before you'd ever need to top up. Credit doesn't expire. No subscription, no monthly bill.
What it's good for
- Voice memos — phone recordings of ideas, todo lists, dictated notes
- Meeting recordings — Zoom / Teams / Meet exports converted to searchable text
- Lectures and talks — podcast clips, conference recordings
- Interview transcripts — for journalism, research, content production
- Voice journals — daily reflection turned into searchable diary entries

When the alternatives win
- Otter.ai Pro if you want real-time live transcription of meetings, with speaker diarization and a permanent searchable archive — that's their core product and they do it well.
- Whisper locally if you have technical skill and a GPU, and you want unlimited transcription with full privacy.
- Otter.ai Free if you're under 300 minutes/month and only need basic features.
When the lighter tool wins
- You only transcribe a few clips a week — Otter Pro's $8-20/mo for 5-10 transcripts works out to ~$1-4 each.
- You don't need real-time / live — most use cases are "I have a file, give me the text."
- You don't want a recurring bill — pay-per-minute on a credit balance.
- You're testing before committing to any paid plan.
A realistic example
A 30-minute Zoom call. You exported the audio, you need the transcript for notes.
Otter.ai Free: hits the 30-min file cap. Need to split or upgrade. AI Pass Voicenote: upload the file, hit Transcribe, ~30 seconds later you have the text. Cost is a few cents.
