## What is Nasu?

Nasu turns your conversations, sessions, and voice notes into clean, searchable text — and everything happens on your device. No cloud processing, no account, no subscription servers. Nothing you record ever leaves your hands.

Built for people whose recordings are genuinely confidential: therapists and counselors, physicians, lawyers, researchers, journalists — and anyone who thinks a voice note shouldn't be someone else's training data.

PRIVATE BY ARCHITECTURE
• Transcription runs entirely on-device, powered by state-of-the-art on-device speech models
• Works fully offline — airplane mode is a feature, not a limitation
• No account, no sign-up
• iCloud sync is strictly opt-in and off by default; analytics can be turned off with one switch

WHO SAID WHAT
• Speaker labels: Nasu tells voices apart and labels every turn in the transcript
• It learns the people you talk to — name a voice once and it's recognized next time
• Voice profiles are saved only with consent, end-to-end encrypted, and deletable any time
• Tap any label to correct it; Nasu learns from your corrections

WRITTEN UP, INSTANTLY
• Short summaries, titles, and tag suggestions — generated on your device with Apple Intelligence
• No server ever sees a word (works on devices with Apple Intelligence; everything else works everywhere)

A CALM, FOCUSED TOOL
• Record and transcribe live, transcribe as you record, or import audio files
• Clean transcripts: filler words ("um", "uh") removed automatically — reversibly
• Custom vocabulary: teach Nasu the names, medications, and specialist terms it should get right
• Folders, tags, and full-text search turn recordings into a knowledge base you can actually find things in
• Timestamps you can toggle, an audio player to check the source, and titles that write themselves

YOUR NOTES, YOUR FORMAT
• Export as formatted PDF or Markdown, or copy plain text straight into your notes system
• Share audio in from any app

MADE FOR ALL YOUR DEVICES
• Native on iPhone and iPad, with a side-by-side library and transcript view on larger screens
• Runs on Apple silicon Macs
• Choose your model: Fast, Balanced, or Accurate — depending on your device and your patience

LANGUAGES
English, French, German, Italian, Portuguese, and Spanish — carefully validated rather than promised. Automatic language detection and translation to English included.

Your words are yours. Nasu just writes them down.
