Thea is a free AI study platform that turns uploaded course material into practice questions, flashcards, study guides, and tests for students in 200+ countries.
About
Thea is an AI-powered study platform that helps students learn their own course material faster through active recall rather than passive re-reading. Instead of simply supplying answers, it generates practice questions, flashcards, study guides, summaries, practice tests, podcasts, and games from material the student uploads, and it adapts each session to what the learner has and has not yet mastered.
Students upload lecture slides, notes, PDFs, images, audio, video, or YouTube links — more than 90 file types are supported — and Thea produces a complete study kit within moments. Its flagship Smart Study mode runs question-and-answer sessions built on spaced repetition and retrieval practice, with the student doing the thinking rather than the AI. Thea was founded by Baker Bruce, who prototyped the platform as a high school junior, alongside co-founder and CEO Anthony Bruce; Theaai Corporation is headquartered in Arlington, Virginia. The service is available in 80+ languages and used in 200+ countries.

Teachers, professors, and tutors can use free educator accounts to build study materials for their classes, while institutions can deploy it with LMS integrations and compliance documentation.
