Free, no-login study tools that turn any topic into a clean formula cheat sheet, an instant practice quiz, and printable flashcards.
Cheat-Sheets.ai is a free study companion for high school and college students. Pick a subject and a topic and you get three things straight away: a reference cheat sheet with every key formula and its symbols explained, an auto-generated multiple-choice quiz to test yourself, and export options to print the material as a compact cheat sheet or a deck of flashcards. There is no account, no paywall, and nothing to install — open the page and start studying.
Every core formula for a topic, each with a plain-English description and its symbols defined, laid out for fast review.
Multiple-choice questions generated for the exact topic you picked, at Medium or Hard difficulty, with the answers worked out.
Stuck on a question? Open an explanation that breaks down why the answer is right — no jargon, no lecture.
Export any topic as a printable cheat sheet sized for a page or an index card, or forge it into a flashcard deck.
The formula sheets are hand-curated per topic. The quizzes and explanations are produced by a large language model (Google’s Gemini) prompted with that topic’s formulas, then cached so everyone studying the same subject gets a fast, consistent result. You never have to enter any personal information to use any of it.
We currently cover math (algebra, trigonometry, geometry and probability), the sciences, social studies and finance. Browse every topic:
Cheat-Sheets.ai is a study aid meant to help you understand and revise concepts.
