TubeMind AI - YouTube Transcript & Summary

TubeMind AI adds a focused sidebar to YouTube watch pages. When captions are available, it loads the transcript and lets you search, copy, and jump directly to matching moments in the video. Use it as a YouTube transcript reader, transcript search tool, and timestamp navigator while you watch. Key features: • Load the available transcript for the current YouTube video. • Search transcript text locally in the browser. • Jump from a matching line to its timestamp in the YouTube player. • Copy the transcript with or without timestamps. • Follow the active transcript segment as the video plays. • Generate an optional AI summary with an OpenAI-compatible provider that you configure. • See a clear unavailable state when captions are missing. • Use the English or Russian interface. Normal transcript search and navigation are local-first. TubeMind AI does not require a TubeMind account or a TubeMind backend service. AI Summary is optional: when you explicitly configure a compatible provider and request a summary, transcript-derived content is sent directly to that provider according to your settings. Useful for students, researchers, content creators, journalists, analysts, and anyone who wants to understand long YouTube videos faster.
