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.
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

• Research and user interviews: import files, label speakers, export clean text
• Client work of any kind: meetings, consultations, coaching

Ratings & Reviews

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
