Math Reasoning Studio is an offline-first, text-only workspace for high school mathematics focused on explanation and reflection. Students draft structured solutions, create misconception cards, and keep topic notes they can revisit and edit over time. Each session saves a learning record and directs learners to review what they wrote, identify misunderstandings, and plan refinements. Mastery follows clear local rules that require attempts plus documented reasoning or reviewed errors. All content is bundled as JSON and all data remains on-device, with no accounts or network access.
