Sunny Personal Tutor · closed beta Q4 2026

An educational harness for AI.

Sunny turns AI into a patient reading and math teacher for kindergarten through fifth grade. It decides what each student learns next, works out the right answers before the AI says a word, checks everything the AI writes, and keeps every student safe.

01 What we've built

Lessons that move. Drawn live, voiced by Sunny.

Sunny teaches new ideas with short animated lessons, each one a little story on a live stage: cubes tip a balance, a cookie is cut into fair shares, a fraction wall lines up its pieces. Students make their own calls along the way, and Sunny talks them through every step.

Real lessons, recorded straight from Sunny, voice and all.

  • Exact by construction

    Every picture is drawn from the lesson's exact numbers. Seven counters are always seven, and three fourths is always three of four equal parts.

  • Students make the call

    Lessons stop for "your turn" moments. A wrong pick gets a kind nudge and the lesson waits until the student finds the right one.

  • Help that climbs

    Stuck on a practice problem? Help steps up as needed: a hint first, then "watch how" with an example of the same kind, then "let's do yours together."

02 Inside Sunny

Reading they choose. Math at their pace.

Students pick a topic they love, and Sunny writes stories and articles about it at exactly their reading level. As their reading improves, the passages get harder, so they keep growing as readers. Math practice adapts skill by skill.

A Sunny nonfiction reading, Eyes in the Sky: How Satellites Help Us, under a painting of Saturn and Earth. The word orbit is tapped, showing its definition: to move in a circular path around something, like a planet or star.
Reading built around what they love. Nonfiction is grounded in vetted reference material, so students learn real facts. New vocabulary is highlighted as they read, with definitions a tap away.
The interest picker: painted tiles for Animals, Space and Astronomy, Dinosaurs, Science, and more.
22 painted worlds to start from, or they can type their own. Every topic is safety-screened for the student's age.

When they're stuck on a math problem

Help that climbs, one step at a time.

A Help button sits under every problem. Each press gives a little more help but never gives the answer away, so the student always takes the last step.

  1. Help: a hint
    A coin problem: how much is 1 quarter, 2 dimes and 4 pennies? Sunny's first hint sits on the card: let's start by finding the quarter, that's the biggest coin.

    A nudge. Sunny points the way without telling the answer.

  2. Help: watch how
    Sunny counts a different set of coins, biggest first: a quarter, a dime, a nickel and a penny make 25, 35, 40, 41 cents.

    A fresh example. Sunny shows the method on a problem of the same type and leaves the rule on screen as a reminder.

  3. Help: let's do yours together
    The lesson on the student's own coins, counting on from the quarter: 25, 35, 45, 46, 47, 48 cents, with the last penny still to count.

    Their own problem. The lesson goes through their actual problem and stops one step before the answer.

  4. Give it a try!
    Back on the problem card, the counted coins sit above the answer choices under the heading Where we stopped.

    Their turn. The picture comes back to the card, so students do the last step with the work in view.

Help is counted honestly. Past the initial hint, a right answer earns half the progress, and a problem of the same type comes back later. If they get that one on their own, Sunny makes sure they know it: "You did that one all by yourself!"

03 Why a harness

Fluency is not teaching.

AI can explain anything, and be wrong about it with exactly the same confidence. For an adult, that's an inconvenience. For a seven-year-old learning subtraction for the first time, a wrong answer delivered warmly is worse than no answer at all.

Produces math that sounds right and isn't.

Sunny works out the right answer first. The AI then explains it clearly, in words that fit the student's age.

Drifts wherever the conversation goes.

Every lesson comes from a structured, standards-aligned plan, so skills build in the right order.

Guesses at what a student already knows.

Sunny gets to know each student: what they've mastered, what's still shaky, and what they're ready for next.

Writes whatever it writes, and you find out afterwards.

Nothing reaches a student unchecked. AI output that misses the mark is sent back, and students only see explanations that are right.

Starts every session from nothing.

Progress carries forward, so every session picks up right where the last one left off.

04 How Sunny works

Layers, not prompts.

Sunny treats the AI as one part of a larger system, not the whole thing. Here is one hint on its way to a second grader. Watch what happens when the AI's first draft gives the answer away.

If a rewrite still misses, Sunny falls back to a hint written by people. The AI never grades a math answer.

  1. 01

    Curriculum

    A map of 188 math skills, grade by grade, aligned to published state standards. Sunny chooses the next skill; the AI never decides what school looks like.

  2. 02

    Correctness

    The answer to every problem, and the steps to get there, are worked out before the AI is asked for a single word. Accuracy is settled before the lesson is written.

  3. 03

    Verification

    Everything the AI writes is checked for answer leaks, false arithmetic, invented claims and reading level before it's shown. Anything that falls short goes back with the reason.

  4. 04

    Grounding

    Lessons about the real world are built from vetted reference material rather than the AI's memory, so a student exploring a favorite subject gets something new, and true.

  5. 05

    Safety

    Anything a student types is screened before a lesson is written, with the bar set for their age. When in doubt, it fails closed. Safety comes before the writing, not after it.

  6. 06

    Mastery that sticks

    Mastery is measured by what a student keeps: a skill only counts as mastered after a hint-free review days later. Knowing something on Friday isn't the same as knowing it in March.

05 What's next In development

A picture for every "I don't get it."

Every student gets stuck somewhere different. We're teaching Sunny to draw on the spot: when a student is confused, Sunny works out what tripped them up, draws the picture that clears it up, and walks them through it step by step.

Isn't 1/3 bigger than 1/2? 3 is bigger than 2.

What Sunny noticed

They think a bigger bottom number means a bigger piece.

See? More pieces means smaller pieces. 1/2 is bigger than 1/3.

Checked before it's drawn
  • Both bars are the same size
  • Every piece is cut evenly
  • Matches the math: 1/2 > 1/3

Sunny will draw with the same tools teachers use, and it will check every picture first: the pieces really are equal, the hops really are the same size, and the numbers really add up. As AI gets better, the pictures can get richer.

  • number lines
  • fraction bars
  • base-ten blocks
  • ten frames
  • arrays
  • balance scales
  • clocks
  • coins
  • graphs

06 Built to last

It gets better as AI does.

Sunny isn't built around any one AI. It can teach reading and math with different AI behind the scenes, held to the same high standards. When more capable AI arrives, Sunny evolves to teach students better without starting over.

The curriculum, the safety standards, the quality checks, and everything we've learned about how students actually learn are built to last.

  1. Built to welcome better AI

    Sunny isn't tied to any one AI. When a better one comes along, it slots right in, and everything students rely on stays exactly where it was.

  2. Better, never just different

    Before any new AI gets to teach a student, it has to meet the same standards as the one it's replacing, on the same evals. No surprises, no backsliding.

  3. The parts that last

    The curriculum, the checking, and the safety are ours, and they keep getting better year after year, no matter what AI is inside.
