An AI tutor that has read the page you are on.
Ask AI opens beside a lesson or a question and already knows what you are looking at. It explains, gives you another one to try, and marks written answers against the real mark scheme.
No account needed to look around.
Ask about this step, not the whole subject.
Because Ask AI knows the lesson or the question in front of you, you can ask the short question you actually have — “why minus nine?” — and get an answer about that line.
- On every lesson and every question, one button away
- Explains, re-explains and sets you a similar problem
- Has its own page for longer conversations
Know which marks you dropped, and why.
Written, drawn and handwritten answers are checked against each marking point of the paper’s own mark scheme. You see the points you earned and the ones you missed.
- Marked point by point, not just “right” or “wrong”
- The mark scheme is shown, so you can check the marking yourself
- Handwritten working can be marked too
How the AI works
Runs on Google Gemini
Ask AI and AI marking both use Google’s Gemini models.
Free with your own key
On the Free plan, or as a guest, paste your own Gemini API key in Settings. It is kept in your browser only and sent just with AI requests.
Included with Pro
On Pro, Ask AI and AI marking are included — there is no key to set up.
Check it yourself
AI can be wrong. The solution and the mark scheme are always on the question so you can verify what it says.
