No account needed. Your child's answers never leave your browser.
Sound familiar?
- Your child's homework looks nothing like the way you learned math.
- You're not sure if your child is really on track, or just getting by.
- Tutors cost a fortune, and you're not sure you need one.
You don't need a math degree. You need a clear explanation, an honest snapshot of where your child is, and a plan that fits your budget.

Questions parents ask
Do I need to be good at math to use this?
No. That's the point. Each Homework Decoder explainer shows how the school method works in plain English and gives you one sentence you can say to your child.
Which grades does it cover?
The Homework Decoder library is planned for kindergarten through grade 8. The free Grade-Level Check currently covers grades 1 to 5, with more grades planned.
What happens to my child's quiz answers?
Nothing leaves your browser. The Grade-Level Check runs entirely on your device, doesn't ask for your child's name, and forgets everything when you close or refresh the page.
How much will the membership cost?
We're planning about $9 to $12 per month or $59 to $79 per year, with a sibling discount. Final prices will be announced at launch.
Is this a replacement for a tutor?
It's a lower-cost way to feel confident helping at home. If your child is struggling a lot, talk to their teacher. A tutor can still be a great addition.

It takes about 10 minutes, it's free, and it's private.
