Gemini can analyse PDF files and images directly in a chat. That is useful when a rulebook has no good index – especially when the question concerns a detail that appears only once.
A useful answer might be: "A figure may move through allied spaces but cannot end there. See page 12, Movement." You can then open the right page quickly and settle the question together.
Gemini requires sign-in. File uploads are available without payment, but free accounts have lower rolling limits than Google AI plans. Large or scanned rulebooks can also be misread.
So let AI find the passage – not judge the game. Always check the page yourself, especially when the exact wording matters.
