Murmur Recorder: Voice to Text

Murmur is the recorder that understands who said what. Record a meeting, a lecture, an interview, or a quick voice memo, and Murmur turns it into searchable text — and tells each speaker apart — entirely on your device. Your recordings are never sent to our servers.

WHY MURMUR

Most transcription apps send your recordings to a server. Murmur does not. Everything happens on-device using a speech recognition model that runs locally on your iPhone. No accounts. No sign-up. We never receive your recordings or transcripts.

KNOW WHO SAID WHAT

Murmur labels each line of the transcript with who said it, color-coded so a multi-person conversation is easy to follow. It builds a library of people across your recordings: name someone once, and Murmur recognizes their voice the next time they appear. Merge duplicates or relearn a voice — the more you correct someone, the better Murmur identifies them in future recordings.

TURNS TALK INTO TEXT

Record, and Murmur transcribes what was said and saves the full transcript alongside the audio. Transcription runs on your iPhone and detects the spoken language automatically.

EXPORT — AND HAND IT TO YOUR AI

Export any transcript as plain text, Markdown, PDF, or Word — with each line's speaker, and your translation if you made one. Share the original audio too. Drop it into Notes, an email, or your favorite AI assistant to summarize, pull action items, or analyze further — on your terms, with your tools.

IMPORT WHAT YOU ALREADY HAVE

Bring in a voice memo, a meeting recording, a lecture, or any audio or video file, and Murmur transcribes it on-device, with speakers labeled — just like something you recorded in the app.

TRANSLATE YOUR TRANSCRIPTS

Turn any transcript into another language, line by line, right inside the recording. Read it as translation-only or side-by-side with the original — all on-device.

WORKS OFFLINE

Because recognition runs on your device, Murmur keeps working on a plane, in a basement meeting room, or anywhere with no signal. Download a model once and you are set.

GREAT FOR LEARNING

Import a speech, a lecture, or any audio you already have, and study it your way: tap a single sentence to replay it, or let the whole recording play with the transcript scrolling along in sync. Many people use Murmur to learn a new language one sentence at a time.

PLAY BACK WHILE YOU READ

Open any recording to read the transcript with timestamps, scrub through the audio, and replay any moment. Tap any line to hear just that sentence.

SEARCH YOUR WORDS

Find a phrase across a transcript instantly, with matches highlighted right where they appear.

MULTIPLE LANGUAGES

Murmur transcribes around 100 spoken languages, and the app interface is available in English, German, Japanese, Simplified Chinese, Korean, and French.

IPAD AND IPHONE

Murmur is a universal app, with a roomier, iPad-tuned layout on larger screens.

SAVES SPACE AUTOMATICALLY

After a recording is transcribed, Murmur automatically compresses its audio in the background, reclaiming storage on your device and in iCloud without losing the transcript or playback.

SYNC ACROSS YOUR DEVICES

Turn on iCloud sync to keep your recordings and transcripts on all your devices through your own private iCloud account. Your data stays in your iCloud — only you can access it.

PRIVATE BY DESIGN

- 100% on-device transcription and speaker identification

Whether you are capturing decisions from a meeting, keeping a record of an interview, or jotting down ideas on a walk, Murmur gives you a clean, searchable transcript that knows who said what — while keeping your conversations yours.
