Upload a PDF, practice what you study.

Study communities where your notes and past exams become practice tests. Every question cites the material it came from. Free, no sign-up.

The problem

Students share PDFs and photos of exams, but nobody turns them into practice.

How it works

• Upload a PDF, notes or a photo of a page; AI on our own GPU turns it into a practice exam.
• Every question must quote the material it came from, checked by text comparison, not by another model.
• Uploaded documents are treated as hostile input, fenced against prompt injection.
• Communities organized as a graph: country, university, degree, course and topic.
