Math Notebook is a Grade 12 reasoning studio. Each session becomes a saved page: your steps, explanation-based notes, mistake context, corrections, and a short reflection. Refining creates a new numbered version, so older work stays visible.

T-Chain Breaker is an offline reasoning inspection studio built for one focused task: identify where a short reasoning chain fails, diagnose why it fails, evaluate downstream impact, repair the broken step, and save a structured Break Card. Each session is closed and intentional, with one chain, one break point, and one saved artifact. The app includes multiple inspection modes, curated local chain content, deterministic validation rules, and a read-only library with revision lineage so your analysis remains consistent over time. No accounts, no feeds, no AI generation, and no internet required at runtime.
