Sigma turns open-ended learning into a guided, mastery-based tutoring loop so you stop guessing and start reliably building durable understanding.
Typical use cases include: preparing for exams by mastering concepts step-by-step, learning technical topics with fewer “stuck” moments, and strengthening long-term retention through review and interleaving.
Use the sigma skill to tutor you on a topic by running: request sigma to teach "quantum mechanics" with a beginner starting level.

Socratic questioning aids mastery learning by guiding you with questions instead of direct answers, keeping you actively reasoning. This ensures you process concepts deeply rather than passively absorbing lectures.
Use an AI tutor for spaced repetition by resuming sessions in a topic-scoped workspace; the tutor re-tests mastered concepts at expanding intervals to prevent forgetting and automatically schedules reviews.
Yes, you can learn any topic with adaptive pacing and an 80% mastery gate. The tutor requires hands-on practice tasks before marking concepts as mastered and adjusts difficulty based on your demonstrated understanding.
AI tutors detect and fix misconceptions by tracking wrong mental models during practice and rebuilding them via counter-examples and contradictions. This diagnoses flawed logic and directly corrects your understanding.
Mastery-based tutoring does not require previous knowledge of the subject, as adaptive pacing adjusts difficulty to your starting level. You can request beginner tutoring for any topic and advance only after demonstrating 80% understanding.
