AI on 4AB

Where 4AB uses AI today. Every tool here also works by hand: AI checks and drafts, a person decides.

3 things to open

AI Answer Checker

Get homework and exam answers checked with AI, or score an objective paper with the marks checker.

Question Bank & PYQs

Previous-year questions exactly as printed — CSIR-NET, GATE and IIT-JAM chemistry, plus general aptitude. Free, by chapter or by exam.

Notes Maker

Topic notes built from the bank: worked examples are real questions with their printed answers, and anything AI drafts is labelled.

How AI is used here. AI reads and drafts; it does not decide marks, prices or payments. Answers in the question bank are the printed ones, not generated. If an AI check looks wrong, report it and a person reviews it. See everything on 4AB in the ecosystem.
