## Description

Practice rigorous problem sets, score attempts with rubrics, challenge friends privately, and turn weak foundations into a daily mastery plan.

Cognexus is an offline-first mastery engine for students who learn through hard problem sets, not passive content checklists.

It combines concept graphs, retention decay, readiness diagnostics, and rubric-scored practice so every session answers one question: what should I study next to build durable understanding?

Use Cognexus to:
- follow prerequisite-aware roadmaps for structured subjects
- practice with 427 bundled course-grade packs across algorithms, discrete math, linear algebra, multivariable calculus, real analysis, and differential equations
- grade attempts with transparent rubrics, confidence, time, and points
- turn practice evidence into retention updates and weak-foundation repair
- scan or paste problem text locally to match it to relevant concepts
- review with retrieval questions instead of rereading
- challenge a friend through private local links that rebuild a plan without public leaderboards
- track weekly progress, calibration, streaks, and mastery movement

Cognexus runs locally and does not require an account, backend, subscription, or API key for the core study loop. Your goals, attempts, scores, notes, and retention evidence stay on your device unless you choose to share a challenge or progress card through iOS.

Cognexus is built for undergraduates and self-taught learners in technical subjects: people who want a study system that treats prerequisites, forgetting, and practice outcomes as first-class data.
