RationalGrid is a free, open-source AI tool built on Elixir/Phoenix LiveView. Ask any question and instead of a flat chat response, you get a node in a visual knowledge map. Branch in multiple directions, collaborate in real time, explore pro/con trees, and export your work. Built for educators, philosophers, and anyone who thinks in graphs rather than threads.
