Unconventionally productive AP study tools.
Built by a 6-AP veteran for a high-stress school with no centralized study materials. AcornPrep packages AP prep into modes that fit how people actually study — unlimited MCQ practice, graded FRQ practice, flashcards, podcasts, mind maps, and study guides, with AI tutor guidance. Released to Mission San Jose on 04/11/2026; 100 users in the first 24 hours, 500+ across the season, 13,000 MCQs practiced. Endorsed by 4 AP teachers, #1 Google result, and rebuilt from scratch with Claude Code on a real dev pipeline. Next: SAT prep. Partner: Pradyun Kanuparthi.

The builder's creed
Build something people use.
Every product here started as a question — what if there was a better way to study for AP exams? What if music supervision had better tooling? What if school clubs were easier to discover? The answer is always the same: build it.
