Everything about how Cheat-Sheets.ai works — free access, no accounts, how the quizzes are generated, and how to use it honestly.
Yes. Every cheat sheet, quiz, flashcard and explanation is free to use. The site is supported by ads, not paywalls, and there are no premium tiers.
No. There is no sign-up, login or password. You do not enter any personal information to use the tools — just open a subject and go.
Each quiz is generated by a large language model (Google’s Gemini) prompted with the formulas for the topic you selected. Generated quizzes are cached by topic so they load instantly for the next person studying the same thing.
We tune the system for accuracy, but AI models can occasionally make mistakes. Treat Cheat-Sheets.ai as a study aid and verify anything critical against your textbook or course notes before an exam.
Math (algebra, trigonometry, geometry and probability), physics, chemistry, biology, US history, world history, macroeconomics, microeconomics and financial math — with more topics added over time. You can see everything on the Browse page.
Yes. Any topic can be exported as a printable cheat sheet sized for a full page or an index card, or turned into a flashcard deck for quick self-testing.
Yes. The site works in any modern mobile or desktop browser, with a dark mode by default and a light mode you can toggle.
No — it is a study reference, like a textbook summary or a set of flashcards. Use it to learn and revise. Do not use it to violate your school’s rules during a graded test or exam.
As little as possible. There are no accounts and no personal profiles. Your study progress — streaks and review cards — is saved only in your own browser (local storage), never on our servers, and you can back it up or reset it anytime. See the Privacy Policy for the full details on caching and technical logs.
