RationalGrid
RationalGrid helps you map the territory of an idea, test it critically, remember what you learn, develop it over time, and share the path with others.
Start here
Ask a question, paste an answer, or name an idea. RationalGrid turns one thought into a grid you can return to, question, and share.
Create a grid
Start anywhere
Use a question, a copied AI answer, a quote, or a rough topic.
Choose the depth
Pick simple, high-school, university, or expert answers next.
Get a reusable grid
Keep the answer, branch from any point, and share the map later.
A grid keeps the answer, the branches, and the next questions together so the work can keep developing after the first AI response.
See how one topic becomes a shared trail of answers, questions, and new directions.
