Cognitive Apprentice
⚡ Inverted AI Apprentice • Bayesian Cognitive Twin

Don’t ask AI for answers.
Teach an AI to discover what you truly know.

Instead of an AI quizzing you, your apprentice Ada attempts challenging university problems and makes subtle, realistic mistakes. Catch her error, explain the broken principle, and watch your Bayesian Knowledge Twin map your mind without standard testing.

The Science Behind Mimir

Three Breakthrough Innovations

Replacing passive multiple-choice testing with active cognitive apprenticeship and asymmetric Bayesian propagation.

01

The Inverted Apprentice

Teaching is the highest form of learning (the protégé effect). Ada solves problems out loud, occasionally stumbling on real student misconceptions. Explaining why her step is invalid activates deep recall far beyond standard flashcards.

02

Bayesian Cognitive Twin

Your knowledge is not a checklist—it is an asymmetric Directed Acyclic Graph (DAG). When you successfully critique a derivative step, positive evidence flows upstream to foundational concepts like limits and powers without re-quizzing them.

03

Vicarious Spaced Repetition

Using Free Spaced Repetition Scheduler (FSRS), Mimir calculates when concepts would decay. By proving mastery of advanced topics, prerequisite review intervals are pushed forward automatically—slashing review fatigue by over 80%.

Experience The Apprentice

Listen to Ada’s Derivation

Ada doesn’t sound like a monotone robot. Listen to her warm, natural human voice explaining calculus step by step.

“Right, so evaluate ∫ 2x·cos(x²) dx. Step 1: Let u = x². Then du = 2x dx...”

Ada reads her complete derivations aloud with human breath sounds, natural pauses, and mathematical phrasing before asking for your critique.

Step 1. Let u = x². Then du = 2x dx, and the 2x dx already present is exactly du.

Step 2. Replacing only the x² by u, the integral is ∫ 2x·cos(u) dx, and since 2x is not part of the cosine I can pull it out front as a constant.
