Research case study
Philosophy Now began with physicist and former semiconductor researcher Ignacio Gonzalez’s article about why some narratives spread and survive. Using RationalGrid, it turned the argument into a 35-point map branching into memetic fitness, human agency, psychological susceptibility, narrative complexity, talking points, and moral motivation. The result keeps competing explanations and follow-up questions connected, giving readers paths to inspect instead of a single linear summary.
“An amazing free specialised AI tool to explore philosophical ideas around pretty much anything—from academic questions to films to… hamsters! All at one’s fingertips, in a matter of seconds, with in-built tools for a sophisticated, yet accessible dialectic. Bravo!”

Curated grids
Find unfamiliar ideas, then question or extend any part.
RationalGrid is a free, not-for-profit, AI-assisted research and argument-mapping tool. It helps students and researchers organize claims and evidence into structured, shareable formats.
Free to explore
RationalGrid is free to use. There are no paid pricing tiers.
Signed-out visitors can use Simple answers. A free account unlocks Expanded and In-depth answers. Each person can have up to three AI requests in progress and make up to ten AI requests per minute; if a limit is reached, wait and try again.
Simple answers do not perform source research unless you ask for it. Expanded and In-depth answers are prompted to ground material claims in relevant primary, scholarly, or official sources, but AI can be wrong and important claims should be checked.
You can—and sometimes should. ChatGPT or Claude is often simpler for a quick answer, draft, or short conversation. RationalGrid is useful when the path matters: it keeps questions, sources, notes, and branches connected so you can return, check evidence, compare views, share, and build with others.
