Complete derivations
Numbered steps with the equation and the justification for each move. Nothing is hidden behind “after simplification”.
The fastest way to learn anything.
Turn your syllabus, PDFs, lecture slides or YouTube lectures into deep, exam-ready notes — step-by-step derivations, labelled diagrams, solved numericals, formula sheets, question banks and predicted questions.

Notes that actually score marks
Every lesson is generated section by section, so derivations and numericals never get truncated to fit a token limit.
📐
Labelled diagrams
Monospace figures with axes, boundaries and symbols, plus a 30-second recipe for redrawing them in the exam hall.
🔢
Solved numericals
Given → formula → substitution with units → arithmetic → boxed answer → sanity check. Every single time.
🎯
Predicted questions
Most-repeated questions, marks weightage tables and high-probability predictions for your next paper.
🔎
Deep research grounding
Optionally cross-checks Wikipedia, Wikibooks, OpenAlex, arXiv and Crossref before writing — with citations.
🔑
Nothing to set up
The AI key lives on the server, so visitors just type a topic and go. Power users can still plug in their own key from any provider.
17 sections in every lesson
