D1 Study Tracker

Capture your notes on missed questions, classify WHY you missed them, and export your error log. For Step 1/2/3 and MCAT prep.

Every wrong practice question is data. D1 Study Tracker turns your notes on those misses into a structured error log — so you stop repeating the same mistakes. HOW IT WORKS • On any study page, press Alt+Shift+E or click "📝 Screenshot your notes" — nothing is captured until you click. • Classify WHY you missed it with an exam-specific error taxonomy (knowledge gap, misread, narrowed-to-2, second-guessed…; a dedicated 8-category system for Step 2 CK/Shelf). • The panel auto-detects the question's subject, system, and ID from the page when available. • Repeat misses are flagged — those are your exam killers. DASHBOARD & EXPORTS • Analytics: weakest systems, dominant error types, errors-per-week trend. • Redo list with a weekly reminder until you clear each missed question. • Export everywhere: Excel (.xlsx), Word (.docx) with screenshots, CSV, ZIP with images, or your own Google Sheet. • Full local backup & restore. PRIVATE BY DESIGN Everything is stored locally on your device. No account required, no server, no tracking. Your captured questions never leave your machine. COMING SOON (in private beta) AI tutor, AI quiz drills, mock-exam generation, spaced-review scheduling, Anki export with images, and a personal reference library — visible in the app today, unlocking soon. Use it with whatever question bank or practice platform you study on — you enable it per-site from the toolbar popup.
