FAQ
Common questions
Will it just give me the answer?
Only if you ask. By default your tutor works through the problem with you one step at a time. Say “just do this one for me” and it works it all the way to the answer, then may offer a similar problem to try.
Can I use it with my teen?
Yes. Chalk is for students 13 and older. You can help set up your teen’s account and sit with them as they ask questions. Everything is explained out loud, so you both hear the reasoning. Students under 18 need a parent or guardian to agree to the Terms.
Do I need an iPad?
No. Chalk runs on iPhone, iPad, and in a web browser. On iPad you can write with Apple Pencil.
What math does it cover?
Chalk covers Pre-Algebra, Algebra 1, Geometry, Algebra 2, Trigonometry, Pre-Calculus, Calculus 1, Calculus 2, Calculus 3 (Multivariable), Statistics & Probability, Linear Algebra, and Discrete Math. Physics and SAT / ACT prep are also available, without guided lessons.
How does the free week work?
Lite monthly offers 7 free days with up to 80 tutor messages for new accounts with no prior subscription or trial, once per person. A payment method is required. If you use all 80 messages, tutoring pauses until your paid plan begins, unless you start or upgrade early. We’ll remind you before the trial ends. Cancel at least a day before it ends and you pay nothing.
