FAQ

How does AI Video Insight work?

Install the Chrome extension, open any YouTube video, and click the extension icon. It extracts subtitles and uses AI to generate a structured summary in the sidebar.

Does it block the video?

No. It runs as a sidebar panel alongside the video, so you can watch and read at the same time.

What languages are supported?

The plugin UI supports 7 languages. Pro users can generate summaries in any of these languages regardless of the video's original language.

Can I cancel anytime?

Yes. Cancel your Pro subscription anytime from your dashboard. You keep Pro access until the end of your billing period.

What if a video has no subtitles?

We'll detect it and offer to open the video in Google Gemini, which can summarize videos even without subtitles.

Is my data safe?

We only process video subtitles for summarization. We don't store your viewing history. Authentication is handled securely through Google.

Can it create study notes or YouTube SEO content?

Yes. The Create tab turns any video into structured study notes (with Anki flashcard export) or a complete SEO pack: keyword strategy, titles, thumbnail text, description, tags and a pinned comment. One generation costs one quota unit and results are cached.
