Show HN: A free tool that turns any AI topic into an interactive, cited lesson A free tool that transforms any AI topic into an interactive, cited lesson has been launched. The tool creates a visual mental map of the subject, allowing users to click on building blocks for deeper exploration, with no videos required. What do you want to learn? Build a visual, interactive lesson on anything in agentic AI — a mental map first, then click any building block to go deeper. No videos. Optional — pick a level and coverage, or leave them and I'll infer. Everything else is tuned automatically: examples are always included, and text depth follows your level.
