CheatGrid holds a library of structured cheat sheets covering technical subjects such as Python, SQL, Docker, React and DevOps, each broken into concepts alongside spaced-repetition flashcards and practice questions. It groups material into roadmaps that set an order for working through a topic, so learners can move from discovery to review without assembling references from scattered sites themselves.

The catalogue is aimed at developers and people studying technical skills, including those preparing for certifications. Day to day, a user reads a cheat sheet on a topic, tests recall with flashcards, and checks understanding through practice tests. Access is subscription-based, with a support team handling account, billing and technical queries.
