An AI tutor that draws back.

Chalk is a shared whiteboard with a tutor on the other side. Write the problem with your pencil, ask out loud, and watch the math get worked out next to your work β€” not in a chat bubble.

How it works

The way a tutor would, if one were sitting next to you.

01
∫ x² dx = ?

Write the problem.

Sketch it out the way you'd sketch it in your notebook β€” with Apple Pencil, a mouse, or your finger.

02
"why is this wrong?"
xΒ² + 5x = 6 β†˜ = 6 / x βœ—

Ask out loud.

"I'm stuck." "Why is this wrong?" "Try another way." The tutor hears the question and reads what you've already written.

03
d/dx (xΒ³) = 3xΒ²

Watch it work.

The next step appears beside your work, in handwriting. Graphs plot themselves. The voice explains what the pen is doing.

Why Chalk

Most AI gives you walls of text. Math doesn't live there.

A real tutor draws the next step beside your work and explains it while writing. We built the smallest version of that β€” and skipped everything else.

From pre-algebra to calc 3 β€” and the math after.

Twelve courses. Every problem has a worked solution, written out the way it would be on a board.

FAQ

Questions, answered.

Who is Chalk for?
Students taking a math class β€” middle school through college β€” and self-learners working through a textbook. If you tend to reach for a pencil before you reach for a keyboard, you're who we built it for.
Do I need an iPad?
No. Chalk works on the web with a mouse, trackpad, or touch. The iPad version adds Apple Pencil.
Is it free?
Yes during the beta. After launch there'll be a monthly subscription; beta testers keep founding-member pricing.
Will it just give me the answer?
Not unless you ask for it. By default the tutor walks you to the answer one step at a time, and asks what you've already tried.
What math does it cover?
Pre-algebra through calculus 3, plus linear algebra, statistics, and discrete math. Twelve courses in all.
How is this different from a chatbot?
A chatbot is a text box. Chalk is a whiteboard. The tutor sees what you've drawn, draws the next step on the same page, and speaks while it draws.
