Nasu: Private Transcription

Offline, with speaker labels

Free · In‑App Purchases

Transcribe sensitive conversations entirely on your iPhone — interviews, meetings, sessions. Speaker labels, summaries, exports. No account, no cloud, no upload. 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.

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
