Show HN: An interface for doing research fast with an LLM

I built ProRead as a new interface for researching anything with an LLM. Instead of chat, you explore topics through an interactive map of ideas. The interface changes the level of detail like when zooming in and out on Google Maps. Click to go deeper, expand branches, and always stay grounded in sources. You still have chat for questions, and can switch to listening seamlessly. Curious if this feels useful!
