How to summarize WhatsApp voice messages with AI

Updated July 2026 ยท 3 min read

There's the long voice note, and then there's the long voice note: 7 minutes of monologue where the useful information amounts to three things. Transcribing helps, but reading a wall of text isn't much better than listening. The fix is the AI summary: the key points of the message in a few lines.

Summarize a voice note in 4 steps

  1. Share the voice note with Matt (long-press โ†’ Forward โ†’ Share โ†’ Matt);
  2. Matt transcribes it in about 3 seconds, on your iPhone;
  3. Tap Summary;
  4. Choose the detail level: Essential, Concise or Detailed.

Not just voice notes

The same AI summary works on endless text messages (share them with Matt from the chat), on infinite threads and on imported files: meeting recordings, lectures, voice memos, .txt and .pdf documents. See also how to transcribe audio files on iPhone.

๐Ÿ”’ Privacy note: transcription stays 100% on-device. Only when you request a summary is the text (never the audio) processed in the cloud, anonymously. Details in the privacy policy.

Frequently asked questions

Can I also summarize long text messages?

Yes: share any text (or import a .txt/.pdf file) with Matt and get a key-point summary.

Does the summary work offline?

The AI summary uses the cloud for top quality; on iOS 26+ Matt can use on-device Apple Intelligence as an offline alternative. Transcription, by contrast, always works without a connection.
