AI subtitles for any video

Fenly is building real-time AI subtitles for videos on the web. Watch a YouTube lecture, a Twitch stream, or an online course in any language - and get accurate, copyable captions translated to your language as the video plays.

Live speech-to-text, AI translation across 100+ languages, and captions you can select and copy - useful for following along, taking notes, or learning a new language.
