Live subtitles, right on your iPhone and your Mac.

duna listens to what is said around you and writes it down as it is spoken, with punctuation, capitals and digits. Every new voice starts a new paragraph. It also makes subtitles for a video or a recording you already have, and exports the text as .txt, Markdown or .srt subtitles.

It speaks Catalan, Spanish, English, Galician and Basque. Each language is downloaded once from Apple's servers; after that, everything happens on the device itself and works offline. Your voice and your text never leave your iPhone or your Mac.

duna is free, with no purchases, no ads and no accounts. It needs iOS 26 or later on an iPhone, or macOS 26 or later on a Mac with Apple silicon.
