51,014 worked solutions. Not just answers.
Every question across 998 math, science, statistics, and CS concepts shows the recognition step, the why it works, and the trap most kids fall into — the part you can't clean-extract from a chatbot. Browse it all free. One plan unlocks the worked solutions.
Math tutors do things we don't — diagnosing learning disabilities, building human rapport, reading body language. If your child needs those, no software replaces them. For the explanation, pacing, and progress-tracking parts, we cover ~90% of what a tutor does at <5% of the price.

Questions parents ask
What's actually free?
All 51,014 questions, every concept page and guide, the interactive maps, and 3 mastery checks a day. You can see the final answer and the first solution step on any question without paying. The full worked reasoning is what the Family plan unlocks.
What does Family unlock?
Every worked solution in full — the recognition step, the why-it-works, and the common trap — plus unlimited practice, up to 5 child profiles, and a parent dashboard that shows you exactly what each kid has mastered and where they're stuck.
How is this different from a chatbot?
A chatbot gives you an answer. We show the reasoning a strong student would actually use to recognize the problem type, written and checked by humans across all 51,014 questions — the part that's tedious and unreliable to extract from a chat tool one question at a time.
Can I cancel anytime?
Yes. Monthly and annual both cancel anytime, and you keep access through the end of the period you've already paid for.
