Coach is an AI tutor. Tell it what's confusing, in your own words or with a photo of the problem, and work through it together, with pictures you can drag.

A sample conversation
- Student: why is P(sick | positive) so low??
- Coach: Good question. Before I explain: what did you expect it to be, and why?
- Student: like 90%, the test is 90% accurate
- Coach: That's the most common guess. Want to see it as a picture you can drag?
An example of the style, not a real student's chat.
It listens first
Coach asks how you got there before correcting you, and checks in on how it's going.
Pictures you can drag
435 interactive widgets across maths, computing and science. Drag, tap and change the numbers, and Coach walks you through each one.
One account, any device

Questions
What is Coach?
Coach is an AI tutor made by Anup Rao, a university professor, for whatever you’re studying, from school maths to university courses. It's built to ask what you think before it explains, to give examples, and to show a widget or a diagram when a picture helps. Because it's an AI tutor, it can make mistakes.
How do I sign in?
Open your invite link, or go to the sign-in page, and choose Continue with Google or Continue with email. Email signs you in with a short code we send you, and the same address is the same account every time.
How do I join?
Coach is invite-only for now: ask whoever told you about Coach for an invite link, or scan their QR code. Without one, you can sign in and join the email waitlist; we email you when a spot opens.
Who can use Coach?
Anyone aged 18 or over. Coach doesn't ask your age, but if you say you're under 18 it stops teaching and suggests a parent, guardian or teacher instead.
What does Coach keep about me, and can I delete it?
Your conversation, what you upload, what you tell Coach about yourself, and your progress on concepts; after each session an AI model writes Coach's notes for next time. You can delete any of it yourself, at once: on the web, Menu → Your data. The privacy policy says it all in plain words.
What are the widgets?
Small interactive pages for one idea each, such as Bayes' rule as a zoom or the birthday paradox. Each one comes with a short walkthrough from Coach. Coach shows one when a picture would help, or ask it for one.
Can it be wrong?
Yes. Coach is an AI tutor and can make mistakes. Check important answers with your teacher or course staff.
How do I report something confusing or broken?
Every widget and diagram has a Feedback button at the bottom, right next to the Helpful and Not helpful buttons, in the chat. Feedback goes to Coach, which remembers it, and to Anup Rao, who runs Coach.
