01 / Ask
Bring a big question, a passing thought, or something you’ve always wondered about. Your first answer starts the grid.
An example starting point
Does AI make us better thinkers?
An idea from the answer
Better output and better thinking are different achievements.
02 / Explore
Ask a follow-up, invite a counterargument, or explain a technical term. Each branch stays linked to the idea that sparked it, all in the same grid.
Two directions from the same idea
Challenge the answer
Could AI make us less independent?
Explain a term
What is “cognitive offloading”?
03 / Return
The grid keeps the path you took. Search for an idea, revisit a highlight, or open a bookmark in Saved for recall, then keep exploring.

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!”

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 use general knowledge without live source research. Choose Expanded or In-depth for answers with source lookup; these levels are prompted to use relevant primary, scholarly, or official sources. AI can be wrong, so check important claims against the original sources.
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.
