Speak naturally. On-device AI voice keyboard with live transcript, pause, writing styles, and translation - private by design.
Speak naturally. dun writes clearly.
dun is the AI voice keyboard that turns what you say into polished, ready-to-send text in Mail, Messages, Slack, WhatsApp, Notes, and every other app. Talk at the speed of thought. dun keeps up.
Dun Pro required. An active Dun Pro subscription or a one-time lifetime purchase is required to use voice dictation, the dun keyboard, writing styles, and translation. Weekly, monthly, and yearly subscription plans are available; prices are shown before purchase.
Unlike cloud-only dictation apps, dun runs speech recognition on your iPhone. Your voice stays on your device. The mic is on only while you dictate. No screen scraping for “context.” No training on your speech.
Why people choose dun
- A real keyboard that also dictates - full layout with status and waveform in the header, so you can fix a word, add an emoji, and keep flowing
- Pause mid-thought without ending the session
- Writing styles you control: Exact, light cleanup, or stronger polish (Kind, Professional, Short). dun never “improves” meaning without your say
- Speak in one language, paste in another. Duns automatically translates your direct voice in that textfield.
- On-device privacy by design! All audio is transcribed on this iPhone; the mic is active only while you dictate
- Dynamic Island Live Activity while you dictate
- No account or login is required. Dun Pro — active subscription or one-time lifetime purchase — is required for dictation and premium features.
Great for
- Long emails while walking
- Slack and WhatsApp replies that sound like you
- Capturing ideas before they disappear
- Bilingual writing without a separate translate app
How it works
1. Add the dun keyboard and allow Full Access (so the keyboard can coordinate with the app and insert text)
2. Allow the microphone
3. Download an on-device speech model once
4. Switch to dun, tap the mic, speak. Pause if you need, stop to insert
Privacy in one line
Audio is transcribed on this iPhone. Optional style polish and translation use Apple on-device Foundation Models when available. We don’t run cloud STT on your voice.
Requirements
iPhone with iOS 26 or later. Apple Intelligence features (styles / translation) need a compatible device.

confused update
fineartworks
updated review-thank you for the speedy response but the app still does not recognize restore purchases and hangs on the paywall after update, my free lifetime version download moved to paid.
Developer Response
I’m sorry Restore Purchases still leaves you stuck on the paywall. My earlier reply suggested it would resolve the issue, and I was wrong. Please don’t purchase again. Email me at litze.pasten.0i@icloud.com with your iPhone model, iOS version, and what happens after you tap Restore Purchases. I’ll investigate the access issue with you.
This update includes stability and quality improvements to make Dun better and more reliable.
