Murmuro: Speech to Text

Know who said what. Speaker-labeled transcripts, summaries and search run on your iPhone — your audio never leaves it. No account, no credits, no per-minute fees.

Murmuro is a private AI transcriber that works completely offline. Record or import meetings, interviews, lectures, and voice memos — on-device AI converts speech to text, labels every speaker, and writes an instant summary. No cloud, no account: your audio never leaves your iPhone.

100% OFFLINE, PRIVATE BY DESIGN There is no server behind Murmuro — the AI transcribes right on your phone: • No audio is ever uploaded • Transcripts are stored only on your device • No account or sign-up required • Works in airplane mode

KNOW WHO SAID WHAT On-device AI speaker detection tells voices apart and labels every line of the transcript, so interviews, meetings, and panel discussions stay easy to follow.

AI SUMMARIES, KEY POINTS & ACTION ITEMS Get an instant AI overview of every recording: a short summary, the key points, action items, and topics. On iPhones with Apple Intelligence, summaries are generated by on-device AI — still fully private.

RECORD OR IMPORT — AUDIO OR VIDEO Tap record and the words appear on screen as you speak, then the full transcript lands the moment you stop. Or share a file in from any app — meetings, memos, lectures, podcasts, and video too: an MP4 or MOV is transcribed straight from its audio. Long recordings are handled smoothly, and transcription is fast: on iOS 26, Murmuro uses Apple's latest on-device speech engine where it can. Live text on screen runs on that same system engine, so it covers the languages your iPhone recognizes.

GREAT FOR • Meetings — AI voice to text with speaker labels and summaries • Interviews — speech to text you can quote with confidence • Lectures & podcasts — turn audio to text and search it anytime • Voice notes — a voice recorder that turns memos into text
