Cuelio — Search & AI for YouTube™ 作者： Andrii Petlovanyi

Cuelio helps you work with YouTube videos faster by turning transcripts, comments, and timestamps into a searchable workspace inside Firefox.

Use Cuelio to:
- search a video transcript by keyword or phrase
- jump to the exact timestamp from a transcript match
- search YouTube comments without endless scrolling
- ask grounded AI questions about the current video with answers tied to transcript evidence
- save useful videos and moments for later

The add-on works on YouTube watch pages and is designed for research, studying, note-taking, content analysis, and finding exact moments in long videos.

Some account-based and AI-related features may require sign-in, usage limits, or a paid plan.
