OneAudio

Record a voice note or upload an audio file, and OneAudio turns it into a transcript, a summary and a saved note.

OneAudio is an AI note taker and audio-to-text tool that runs on OpenAI's GPT 4.1 model across all of its plans.

The free plan is small: up to 5 saved audio notes, 10 minutes of audio per month, and recordings capped at 5 minutes each.

That is enough to test whether the summaries suit you.

Plus costs $6 a month and raises the limits to unlimited saved notes, 1,200 minutes of audio monthly and 30 minute recordings.

It also adds file upload, original audio downloads, bookmarks and an option to rewrite summaries with AI.

Amplify costs $24 a month and removes the monthly minute cap, with recordings up to 40 minutes.

Uploads and rewrites only start on paid plans, so the free tier works best as a short trial.

Heavy meeting or lecture users will want Plus at minimum.
