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.
