About Nasu: Private Transcription
Nasu transcribes conversations you can't upload. Everything runs on your iPhone — the audio never leaves it. There is no account, no server, and nothing to sign. Transcription, speaker labels, and summaries all run on the device. When a conversation is confidential — an interview, a client meeting, a session — a cloud transcriber's privacy policy is a promise. On-device processing is the absence of the problem. WHAT YOU GET Nasu transcribes on this device. Recording and export are never gated. • Free — record any conversation. The first three transcripts are complete; after that, new transcripts stop at ten minutes. • Nasu Unlock (one-time) — unlimited transcript length, speaker labels, and custom vocabulary. • Nasu Pro (optional subscription) — everything in Unlock, plus structured summaries and note templates (including SOAP and DAP for clinicians) drafted on this device. 7-day free trial, then monthly or yearly; cancel any time in your Apple ID settings. WHO SAID WHAT • Speaker labels on every turn (Nasu Unlock) • Two-person mode for 1:1 conversations • Name a voice once, with consent, and later recordings label it • Tap any label to correct it MADE FOR CONFIDENTIAL WORK • Journalists: record an interview, get a labeled transcript — your source's words never touch a server • Research and user interviews: import files, label speakers, export clean text • Client work of any kind: meetings, consultations, coaching • Clinicians: SOAP and DAP note templates (Nasu Pro), a client roster, initials-only display, and a review step before any note is done PRIVATE BY ARCHITECTURE • Transcription, speaker labels, and summaries run entirely on this device • Works in airplane mode • No account, no sign-up, no analytics SDK • iCloud sync is opt-in and off by default — it uses your iCloud, not ours • Voiceprints are stored only with consent, encrypted, and deletable • Face ID / passcode lock RECORDING • Record live, transcribe after, or import a file • Recording continues with the screen locked • Custom vocabulary for names and technical terms (Nasu Unlock) • English, French, German, Italian, Portuguese, and Spanish Export Markdown, PDF, or plain text — never gated. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ What you record stays on your iPhone. Nasu just writes it down.
What’s new
Version 5.2 · Updated October 13, 2026
Nasu has a clearer name: Private Transcription. Same app, same privacy. Everything still runs on your iPhone — now the App Store page says what Nasu is for: any conversation you can't upload. Interviews, meetings, research, sessions. • Nothing moved, nothing removed, nothing new to pay for • Clinicians: SOAP and DAP templates are right where they were (Nasu Pro) • Small fixes and polish
