About RationalGrid
Better questions deserve somewhere to go.
RationalGrid turns AI conversations into visual, shareable trails of questions, answers, evidence, and new directions.
What is it?
A workspace for thinking in public.
A grid keeps the shape of an inquiry visible, so you can follow branches, revisit ideas, and invite others into the same context.
Why does it exist?
Because useful thinking should not disappear.
Chat is excellent for a quick answer. RationalGrid helps you keep the questions, trade-offs, sources, and insights that come after it.
How does it work?
- 1 Start with a question, idea, or copied answer.
- 2 Branch into explanations, objections, evidence, and next questions.
- 3 Save, share, and keep developing the map.
Who is it for?
Anyone working through a question.
Students, researchers, teams, educators, and curious people can use it to make complex topics easier to explore together.
Is it free?
Yes. RationalGrid is open access and not-for-profit.
The project is open source and built to make better shared thinking available to more people.
Who is behind it?
A small team building a better way to think together.
