A few useful details.
Caption-based AI can miss things. Keep the original video available when accuracy and context matter.
Which videos does it work with?
Captioned desktop YouTube watch pages. Visual-only information may be missed, and AI selections or answers can contain errors. Highlights and chat use the captions of the current video.
Does it create a downloadable shorter video?
It plays selected passages from the original video inside YouTube. It does not export an edited video file.
What happens to the video text?
Video titles, captions and chat context go to the FunCove hosted service and its AI provider for processing. Conversations are saved in local extension storage. Read the product privacy policy for details.
Can I recover a paid account?
Use Restore account and confirm the code sent to the original payment email. This reconnects the paid account and its existing subscription allowance. Free accounts without a purchase email cannot be recovered.
