Repo Mastery turns real repositories into architecture maps, guided lessons, flashcards, drills, and proof that you understand the system.
Private repo support, local analysis, and cloud analysis depend on your selected workflow.
Every team pays for shallow understanding, in slower delivery, weaker reviews, and knowledge that walks out the door.
New codebases take too long to understand.
AI can generate code faster than engineers can explain it.
Onboarding is inconsistent.
Architecture knowledge lives in a few people's heads.
Engineers struggle to explain real systems in interviews, reviews, and promotion conversations.
Five steps take you from a repo you barely know to a system you can explain and defend.
Point Repo Mastery at a public sample or your own private repository.
We map the architecture, workflows, entities, and risks automatically.
Guided lessons take you through the system in the right order.
Flashcards, quizzes, and drills turn recognition into recall.
Earn a mastery score and a proof portfolio artifact you can share.
One repo becomes a full learning surface: intelligence, practice, and proof.
