Who hurts
Professional exam candidates — nursing boards, CPA, actuarial, medical residency.
The problem
Spaced repetition works and almost nobody uses it, because writing 800 good cards is a bigger job than reading the book twice.
What you build
Upload the material, get cards generated at the level the exam actually tests — application, not definitions — scheduled properly, with each card linked back to the source page so a wrong answer is one tap from the explanation.
Why now
Card quality was the blocker for a decade of attempts. Generating cards that test application rather than trivia is now reliable enough to trust.
Validate it this week
Generate a deck for one exam's most-used textbook and give it away in that exam's subreddit. Card quality complaints will be specific and immediate.
Why you'd keep winning
Exam-specific question style. A CPA candidate can tell within five cards whether you understand their exam, and generic tools never do.
The honest risk
Anki is free, beloved and has a shared-deck ecosystem. You are selling the hours of card-writing, not the algorithm — price accordingly.
The prompt is written to make an AI argue with you before it writes code — that first round of pushback is worth more than the scaffold.
