School pilot · Spring 2027
Plato’s Tutor teaches math the way Socrates taught Plato.
It does not hand over answers. When a student is stuck, it looks for the step where their reasoning broke and asks the question that leads them back across it.
It is free for every student. We are starting with high school math, for students 13 and up.
Student3x + 5 = 20. I moved the 5 over, so 3x = 25 and x = 25/3?
Plato’s TutorLook at the left side. What is the 5 doing to the 3x right now?
StudentAdding to it. Oh. So I subtract it: 3x = 15, and x = 5.
Plato’s TutorCheck it before you trust it. What is 3 times 5, plus 5?
The problem
A class can only move at one speed, so someone is always lost and someone is always waiting.
Left behind
28%
of US eighth graders were proficient in math in 2024. When a class moves on before a skill settles, the gap does not close. The next lesson gets built on top of it.
Left waiting
11 to 30%
of elementary and middle school students already work at least a grade ahead in math. For them, a lot of class is waiting for everyone else.

How it works
Four steps that repeat as a student grows
-
1
Find where they are
A 10-minute check shows what your student already knows and where the gaps start.
-
2
Keep track
It remembers which skills are solid, which are still shaky, how fast they move, and what they care about.
-
3
Ask, then ask again
When they get stuck, it finds the step where their reasoning broke and asks about that one step.
-
4
Show what changed
Every week, students, parents, and teachers get a short note on what clicked and what comes next.
It works at both ends of the class. For a student who is behind, it slows down and rebuilds the skill underneath. For a student who is ahead, it moves on as soon as they are ready, instead of making them wait.
Who it helps
Both ends of the class, and the adults around them
Students who are behind
They go back to the skill that never settled and rebuild from there, one step at a time.
Students who are ahead
They get harder problems as soon as they are ready, instead of another week of review.
Parents
They get a short note each week on what clicked, what still needs work, and one way to help at home.
Teachers
Teachers in the pilot help decide what the classroom view shows, starting with where each student is stuck.
Why it asks before it tells
Students who are handed answers do worse once the help is gone
In a 2025 study of nearly 1,000 high school math students, the ones who leaned on a chatbot that gave out answers did 17% worse on exams once it was taken away. A version that gave hints instead avoided most of that harm. Socrates worked this out long ago. He asked a question, then the next one, then the one after that, until the person across from him realized the answer had been theirs all along.

Privacy
A student should be able to get things wrong here without it following them
Free, with no ads, ever.
We never sell student data.
Parents and schools decide what is kept and who sees it.
Ages 13 and up at launch.
The founder
It started one student at a time
“I have tutored classmates in math for more than 100 hours. Some of them were lost, and some were bored, waiting for the rest of the class to catch up. Somewhere in those hours the idea began to change shape. If the slow, question-by-question help I was giving actually worked, why should it only reach the few students who happened to sit across the table from me?”

Bring Plato’s Tutor to your school
We are looking for a few teachers and schools to try it first and tell us where it falls short. Students never pay, and pilot schools do not either.
