Family alpha · Grades 6 to 8
Generic AI gives the answer. Keystone actually tutors.
Your child learns an idea, then explains it to PIP, a curious AI learner who keeps asking why. You see what they can do with the AI switched off, and the answers behind every number.
A small family alpha, opening a few places at a time. No ads, no trackers.
Your child can answer it. Can they explain it?
Twenty-five minutes on an ordinary evening, in three steps.
Learn it
A short lesson and a few questions on one idea. A wrong answer comes with the steps to get there, never just the answer.
Teach it to PIP
Your child explains the idea in their own words. PIP asks why it works, then where it stops working, until the explanation holds or cracks.
Prove it on their own
Once a week, a short check with PIP and hints switched off, on topics from days before. That is the number we trust most.
What you see each week
One honest sentence first, then the evidence. Every number opens to the question your child saw and what they wrote, so you never have to take a score on trust.
If your child asks PIP for help in the middle of a quiz, the rest of that quiz counts as practice. Getting help is fine. It just doesn't get dressed up as mastery.
Maya worked on 3 days and is getting stronger at fractions. Worth a look: she asked PIP for a quiz answer twice, and PIP coached instead.
On her own: 4 of 5 right, up from 3 of 5
Which is bigger, 1/3 or 1/8?She chose 1/8.
Fixed a mistake from last week
Explained dividing fractions to PIP: B
how many quarters fit in a half? two. so you get more pieces. She answered every one of PIP's follow-up questions.

What we can show you, and what we can't yet
Working today
- PIP won't do your child's work, and help asked for mid-quiz counts as practice, not points.
- A weekly check with the AI switched off, kept apart from practice.
- Every number on your page opens to the answers behind it.
- 338 topics across eight subjects for Grades 6, 7 and 8, mapped to the Texas standards.
- Built to work with a keyboard and a screen reader.
Still measuring, with our first families
- How much a term with Keystone moves what a child can do on their own.
- Whether a few evenings a week becomes a habit that lasts.
- What it costs to teach one idea well.
We'll share the numbers when we have them, including the ones that disappoint.
You stay in charge
Nothing switches on without you.You approve each AI feature for your child, and you can turn any of them off.
No ads, no trackers.Your child's record is your family's. You can download it or erase it at any time.
A safe answer when it matters.If a child writes something worrying, PIP shows fixed, reviewed words and crisis help, never an AI reply.
Why we built it
“I built Keystone for my own sixth grader. Every AI tool we tried was happy to do the homework. None could tell me whether the idea had landed. This one can, and it tells me when it hasn't.”
