Track and learn things in a path

I used to save tons of learning resources — YouTube videos, GitHub repos, articles — but they were all scattered and hard to revisit.

So I built a small tool for myself ：

Turn any link into a card, then organize those cards into structured learning paths.

Core ideas:
• Save resources as cards
• Drag to reorder into learning paths
• Fork and remix other people’s paths
• Stop collecting, start structuring

I’m using it to organize:
• AI agents resources
• LLM tutorials
• React full-stack learning
. Skills

Would love feedback:
Does this workflow make sense?
What would you want added?
