Is CofilmAI Chrome Extension safe?

Clean risk

CofilmAI Chrome Extension sends the current YouTube video URL and caption-track URL to Cofilm's summary API.

When you click Generate Summary on a YouTube page, the extension reads the current video URL and looks up the page's available caption track. It then sends the video URL, selected output language, and caption-track URL to Cofilm's YouTube summary endpoint so the service can generate the summary.
