One adaptive engine, multiple subjects. Each product wraps a shared multi-vector scheduling kernel — recall, storage, and goal — and adds the subject's own content, assessment, and pedagogy.
PMHNP Companion
TestFlight · iOSAn independent study aid for the ANCC PMHNP-BC psychiatric nurse practitioner board exam. Adaptive practice across the five exam domains with worked examples, productive failure, retrieval drills, and a calibrated readiness model that tells learners where they stand. Original educational material — no reproduction of certifying-body materials, no clinical decision support.
Algebra
In developmentAdaptive algebra mastery. Generative templates produce items at the difficulty a learner actually needs; a prerequisite graph keeps work in the right order. The same scheduling kernel repointed from clinical content to mathematical reasoning.
Music Theory
In developmentLayered foundations from the chromatic scale through voice leading, with ear training as a first-class learning modality. Built around how musical knowledge is genuinely hierarchical — you cannot learn tritone substitution without dominant sevenths.
What sits underneath
Each product is a thin content layer on top of a shared engine: a multi-vector expected-utility selector that decides what to drill next based on current recall strength, long-term storage, and learning goal. Calibration is per learner; selection is structural; content is what changes between subjects. Improvements to the engine compound across everything we ship.
