duna: live transcription

Captions on your device

Free

duna turns speech into text as people talk. Put your iPhone or Mac nearby, tap (or click) the screen and read. MADE FOR READING • Text rolls up line by line and holds still: words you have already read do not move. • Punctuation, capitals and numbers as digits, added as people speak. • When a different person starts speaking, a new paragraph usually begins. • Large type you can resize, and four typefaces, two of them designed for low vision (Atkinson Hyperlegible). • Light and dark mode. PRIVATE, FOR REAL • Everything happens on your iPhone or Mac. No audio or text is sent anywhere. • After a one-time language download, it works offline, in Airplane Mode too. • No accounts, no ads, no tracking. Free. MORE THAN LIVE • Make subtitles for a video or recording you already have: duna writes an .srt file on the device. • Correct the subtitles line by line in an editor, then export the video with the captions burnt in (on iPhone it goes straight to Photos). • Every transcription you stop is kept in a folder, where you can rename, edit and export it. • Add names and terms to the vocabulary so they are recognised better. • Export the transcript as text, Markdown or .srt subtitles. • Share a video to duna from Photos, Files or any app to make its subtitles. • Shortcuts actions, and a Control Center button on iPhone. LANGUAGES • English, Spanish, Catalan, Galician and Basque. Galician and Basque are the newest and make more mistakes. • The app stays small: pick a language and download it once (120–195 MB). • The app itself speaks all five languages. duna is an automatic transcription and can make mistakes. It is not a hearing aid and does not replace professional captioning.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

• Correct the subtitles of a video line by line: split, join, add a missed line, find and replace. • Export the video with the captions burnt in: choose 1, 2 or 3 words at a time, size, typeface, shadow and position. On iPhone it goes straight to Photos. • Every transcription you stop is kept in a new folder, where you can rename, edit and export it. • Vocabulary: add today's names and terms so they come out right. • More reliable language downloads.
