A personal AI math tutor for schoolwork and olympiad problems. Lexicor sees your child’s work, asks useful questions, and helps them build their own reasoning.

LOOK FOR A SHORTCUT01
Can you find 1 + 2 + 3 + … + 20 without adding one number at a time?
1 + 202 + 193 + 18
Each pair makes 21
LLexicorONE USEFUL QUESTION
“If each pair makes 21, how many pairs can you make?”
THE NEXT STEP IS THEIRS
“Ten pairs. So it’s ten times 21!”

Understanding comes first.
Support when it’s hard.
Room to go further.
Your child might need help with fractions and love a tricky puzzle. We’re building one tutor for both: a place to strengthen understanding and explore what comes next.
Find a way forward.
Lexicor uses what they’ve written and said to ask a useful question—whether they’re revisiting a concept or testing a new approach.
Let them take the step.
They try again, explain their idea, and work toward that satisfying “I figured it out.”
Same child. Different challenges.

THE PROBLEM01 / 03
“Why can’t I add the bottom numbers?”
⅓ + ¼ = ?
Do the pieces match?
They know the numbers. The next step hasn’t clicked yet.
A QUESTION FROM LEXICOR02 / 03
“Adding the bottoms gives 2/7. Is that more or less than ⅓ by itself?”
A quick check shows why the shortcut fails. The bars show the pieces don’t match.
THE NEXT STEP IS THEIRS03 / 03
“2/7 is too small! Cut both into twelfths first.”
4/12 + 3/12 = 7/12
An answer they can explain, and a reason the shortcut can’t work.
For parents
See what they understand.
And what could come next.
A finished worksheet tells only part of the story. Our goal is to show where your child needs support, where they’re growing, and where they’re ready for a challenge.
- What they worked on.
- What they could do themselves.
- What to revisit—and where to stretch.
Parent updates are part of the proposed pilot.
Beyond the answer.EXAMPLE UPDATE
- Today’s discovery
- Using equal-sum pairs to simplify a long addition problem.
- A moment of independence
- After one question about the pairs, they counted them and found the total themselves.
- Since last time
- Last week they added the numbers one at a time. This week one question was enough for them to see the pairs.
- Still working on
- Explaining why every number is included exactly once.
- A next challenge
- “Would the same approach work for 1 + 2 + … + 21? What changes?”
A few good questions.
Who is the first pilot for?
We’re inviting families interested in school math, deeper exploration, or olympiad preparation, from elementary school through grades 6–7. Tell us your child’s grade and goals so we can discuss whether the pilot is a fit.
Is this only for children who find math difficult?
No. A child can need support with one topic and be ready for a challenge in another. We’re designing Lexicor to support both school foundations and the reasoning behind more demanding olympiad problems.
Is this ready to use today?
We’re collecting interest for an early-access family pilot. Joining the list starts a conversation; it does not purchase a subscription. We’ll share availability, setup requirements, and any pricing before you decide to participate.
What would my child need?
The proposed experience uses paper, a pencil, and a phone or tablet with a camera and microphone. We’ll confirm supported devices and help families with setup before the pilot.
How will you handle my child’s privacy?
Before you enroll, we’ll explain what the camera and microphone capture, what is stored, and how to request deletion. You’ll be able to review those details before deciding whether to join the pilot.
Does this replace a parent or teacher?
Lexicor is being designed as additional learning support. We want to give children useful guidance while keeping parents involved in their progress.
