About Sonii

Sonii is an iPhone app for AI voice cloning and video translation. The user uploads or records a short audio clip, the app clones the tone, pitch and delivery, and that voice can then read any text through unlimited text-to-speech or custom personas. The listing is rated 18+ and says voice data is encrypted and not shared or used without the user's permission.

The video side translates and dubs a clip into other languages in the speaker's own voice, keeps the background audio, and adds subtitles automatically, including clean burned-in captions for portrait and landscape videos. It is aimed at creators who want to localize YouTube, TikTok or Instagram videos, at businesses translating product demos and tutorials, and at casual users making personalized audio messages or audiobooks. The app is free to download with in-app purchases, and a premium subscription removes the cap on voice clones and adds HD video exports.
