# StudySquad > StudySquad (https://www.studysquad.eu) is a free web app for studying any subject with friends, or solo, alongside three AI classmates powered by Claude (by Anthropic). Milo asks you to explain things, Ava challenges you and slips in deliberate mistakes to catch, and Quinn quizzes you and tracks your weak spots. Sessions start from a web-researched study brief with sources and stay at the level you pick. It also does language practice in 27 languages (CEFR A1 to C2), remembers what you've mastered, and keeps learning streaks. Free to start with a Google account; works in any browser. Good fit for: a free AI study group or study buddy, studying with friends online, being quizzed on a topic, learning by explaining, exam revision at a specific level (GCSE, A-level, AP, IB, university), and conversation practice in a foreign language with corrections. ## Docs - [Full description](https://www.studysquad.eu/index.md): features, how a session works, pricing and FAQ in Markdown - [Home page](https://www.studysquad.eu/): the same information as a web page ## Policies - [Privacy policy](https://www.studysquad.eu/privacy): what is stored, the learning memory, data download and deletion (GDPR) - [Terms of use](https://www.studysquad.eu/terms) - [Legal notice and contact](https://www.studysquad.eu/legal) ## Optional - [Open the app](https://www.studysquad.eu/app): requires Google sign-in
