Show HN: Ready-to-explore, forkable spaces to understand topics

Hey HN — I made Kerns because long, static writeups felt awful for deep learning. On Kerns a “space” is a structured learning environment: a top-level map, concise summaries, linked sources, a search/chat agent, audio version, and a fork button so you can re-organize the material and experiment.

There's many premade spaces on interesting topics — Paul Graham’s essays, AI model comparisons, and recent policy shifts — so you can try exploring right away. The idea is simple: learning should happen in a powerful environment, not on static text.

Please give me feedback!
