How it works
Upload the fleet manual
Drop in a chapter PDF. Text is extracted in memory.
Claude Sonnet writes questions
Prompts enforce language, difficulty tier, and type (MCQ, true/false, free text). Correlation-tier questions use a separate prompt forcing scenario framing across chapters.
Admin reviews + publishes
Generated questions land in an admin queue. Approved questions are released to the right fleet (A321 to B777).
Fleet-aware content
Every question, quiz, and pilot is tagged by aircraft. Pilots only see questions for the fleet they fly.
Daily quiz per chapter
One quiz per pilot, per chapter, per day. Score updates wrapped in prisma.
Mastery tracking
Per-pilot, per-chapter, per-difficulty mastery. Four levels: rote, understanding, application, correlation. See where you're sharp, where you're not.
Why this exists
Airline pilots study dense PDF manuals for every fleet they fly. Revision is chapter-by-chapter, daily, repetitive. Existing tools are either paper or built for initial training, not maintenance. GeoStudy is the app a pilot would want if they had to re-qualify on the A350 next month. The correlation tier is the differentiator: scenario questions that combine two or three knowledge areas in an operational situation, the kind of thing recall apps don't do.
