Murmuro: Speech to Text

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 phone.

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 — generated on your device, not in the cloud.

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, even hours-long takes. Live text on screen needs Android 13 or newer and a supported language; the saved transcript needs neither.

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

90+ LANGUAGES, AUTO-DETECTED
The multilingual Whisper AI recognizes more than 90 languages and can detect the language automatically — offline speech recognition with no setup.

YOUR TRANSCRIPTS, ORGANIZED
• Full-text search across every transcript
• Favorites for quick access
• Re-transcribe any recording with a better model
• Export to PDF, Word (.docx), SRT or VTT subtitles, Markdown, CSV, or HTML — or share as text

CHOOSE YOUR AI MODEL
Pick from multiple Whisper model sizes to balance speed and accuracy — up to Large v3. Models download once and then transcribe fully offline. You can even import your own GGML model.

FREE AND PRO
The free plan is genuinely useful: record and import up to 10 minutes per item, transcribe in 90+ languages, search, play back, and share as text. Murmuro Pro unlocks unlimited minutes — no credits, no quotas, no per-hour charges, and still no account — plus the best-accuracy models, speaker labels, AI summaries, every export format (PDF, Word, SRT & more), and re-transcription. Take it monthly or yearly, or unlock it once for life.

IN YOUR LANGUAGE
The interface is available in 100 languages — pick yours in Settings.
