Klarsono by Loïc Demanou

Klarsono dubs the video while you watch it: the original voice fades, the translation speaks. Online courses, conferences, documentaries, streams — on any video player, and even when there are no subtitles.

What it does
- Dubs any video into 47 languages, out loud.
- Works without subtitles: the audio is transcribed as it goes, then dubbed.
- Summarises the video, timestamped, so you can decide whether it is worth watching.
- Runs on any site with a player, including inside embedded frames.

What it costs
- Free with your browser's own voice, no limit, on subtitled videos.
- 6 minutes of HD voice to try, no card required.
- Paid plans will open later; nothing is sold today.

What it does not do
- Audio is never kept: it is transcribed as it passes, then forgotten.
- No ads, no advertising trackers, nothing resold to anyone.
- Zoom and Meet are not supported.

Klarsono needs an account for HD voice, because speech synthesis costs money. You can export all your data and delete your account in one click, from your account area.
