Show HN: I built a map based interface to understand anything deeply with AI (proread.ai)

I like using LLMs to get summaries, but then I often want to deeply compare docs, read parts of the original, and ask questions as I go, all the while doing some note taking to keep track of my progress. I built out an interface to help do all of this coherently - in the space above I was comparing gpt/claude/gemini model cards for instance. Looking for feedback!
