Matt TranscriberNot just WhatsApp voice notes: the meeting recording you need to review, the lecture to study from, the voice memo recorded in the car, the interview to write up. On iPhone you can turn any audio file into text — without uploading anything to web services and without paying per-minute transcription fees.
Transcribe an audio file in 4 steps
- Open Matt on your iPhone;
- Tap Import file and pick the audio (from Files, voice memos or other apps);
- Matt transcribes it entirely on-device, even offline;
- Read, copy, save — or tap Summary for the key points.
Alternatively, share the audio with Matt straight from any app's Share menu, exactly like a WhatsApp voice note.
Typical use cases
- Meetings: record (with participants' consent), import, and get minutes + summary with 3 detail levels;
- Lectures and talks: transcribe hours of audio and search the text by keyword;
- Voice memos: ideas recorded on the go become written, searchable notes;
- Documents: import .txt and .pdf files too, to summarize or translate them.
🔒 Privacy: unlike online transcription services, your audio is never uploaded to a server: Apple speech recognition runs on your iPhone. Ideal for confidential work content.
