I built an website that turns YouTube lectures into mind maps automatically
When I study from YouTube lectures, I always end up doing the same thing:
pause → write notes → rewind → pause again → write more notes.
It completely breaks the flow of actually understanding the lesson.
So I built a small tool that turns YouTube lectures into structured mind maps automatically.
Here’s how it works:
- Paste a YouTube video link
- Choose how detailed you want the mind map
- The AI analyzes the video
- It generates a structured mind map of the concepts
Each branch becomes a topic, and the subtopics contain explanations and key ideas from the lecture.
You can also enable timestamps, so each topic links to the exact moment in the video.
It works well with pretty much any study content — lectures, tutorials, explainers, etc.
It can also generate mind maps from:
- PDFs
- long texts
- class notes
So instead of worrying about taking notes while watching a lecture, you can just focus on understanding and review the generated mind map afterward.
I also made a short demo showing how it works with a lecture video:

Curious if something like this would actually help other students.
If anyone wants to try it or give feedback:
www.mindmap-ai.cc
What features would make something like this genuinely useful for studying?
