faq

will my school know?

No. The extension runs locally in your browser. Nothing is sent to your school.

what subjects does it work for?

Physics, maths, chemistry, biology β€” anything with questions on a webpage. It reads the page and solves what it finds.

is it always right?

It uses Claude AI for hard questions. Very accurate but not 100% β€” always sanity-check important answers.

what's the difference between free and premium?

Free gives you 15 questions a day. Premium is unlimited, uses Claude AI for harder questions, and includes full step-by-step working.

can I cancel anytime?

Yes. Cancel in one click from your Gumroad dashboard. No questions asked.
