Paper-first AI tutor
A tutor for Pre-K through 8th grade.
Koda watches a real paper worksheet on your kitchen table — math, reading, spelling, science, and the focus-and-movement skills underneath (especially for ADHD). Launching with math for grades 2-5. The pencil stays in your child's hand. On-device, in your home; camera frames never leave.
On-device, in your home — never the cloud. COPPA-compliant. Built for ADHD, dyscalculia, dyslexia, dysgraphia, autism.

One product. Six kinds of kid.
Koda is a single setup on the kitchen counter, but it's not a single use case. Pick the closest match to what's happening at your house.
- If your child isa kindergartener learning to count.
Pre-K and K math is 'Next up' on the catalog roadmap — counting, ten-frames, shape sense, number tracing — following the paper-and-manipulatives approach kindergarten teachers use. The math catalog ships at launch with grades 2-5; Pre-K and K follow.
What we teach in early grades → - If your child isa 3rd grader still working on multiplication.
Koda meets them where the work is. Concrete first — equal groups, arrays, number lines — before the times-table drill.
What we teach in grade 3 → - If your child isa 5th grader headed into state tests.
Exam mode runs the test silent — no hints, no voice. After the timer, Koda walks through every miss with your child, naming the small idea behind it.
How exam mode works → - If your child isa 7th grader hitting pre-algebra walls.
Variables and equations are where a lot of kids stall. Koda's verifier checks every step exactly, so stuck doesn't have to mean lost. The hint ladder hands the next move back, never the answer.
What we teach in middle grades → - If your childlearns differently.
Set the support flag at enrollment and Koda picks safe defaults — different combo per flag. Wired today: dyslexia font, animation speed, focus-chunk length, per-profile volume. ADHD, dyscalculia, dyslexia, dysgraphia, autism — twice-exceptional kids combine flags. (More flag-specific defaults follow in software updates.)
Read the ADHD playbook → - If you havekids at different grade levels.
One device, multi-child profiles. Each kid's adventure-track, persona, and accommodations stay theirs. Face recognition routes who's at the desk.

Math is deepest. Four more subjects ride alongside.
The catalog grows in software updates. Same device, same parent report — the breadth deepens over time without you doing anything.
- MathDeepest at launch
Pre-K counting through 8th-grade pre-algebra, mapped to Common Core. 188 short explainer videos at grades 2-5. Verifier checks every step exactly.
- Reading comprehensionShips with starter content
Comprehension prompts on real books and printed text. Vocabulary in context. The camera reads what your child wrote underneath the passage.
- SpellingShips with starter content
Visual + auditory drills. Words written on paper, checked by the camera. Patterns first, then the irregular ones.
- ScienceShips with starter content
Hands-on experiments paced for the grade band. Observation prompts, written conclusions, the scientific-method scaffolding.

Movement breaks and short executive-function exercises drawn from the EF literature. Ships with starter content; the catalog grows over time.
A typical session, in under a minute.
Your child sits down. Koda recognizes their face. The worksheet opens. The pencil starts moving. The tutor watches and asks.
Three things, in a loop.
No screen time. No tablet propped against the cereal box. The child writes; the camera watches; the tutor asks.
- 01Worksheet on the table.
Your child opens any paper worksheet — a homework page, a printable, the back of an envelope. The overhead camera looks down at the paper.
- 02Koda watches and asks.
Koda reads what your child wrote. When the work shows a slip, Koda asks a small question. When it's clean, Koda says so.
- 03Your child writes the next step.
The pencil keeps moving. Koda doesn't give the answer. The work stays in the notebook — at the end, it's still your child's.
Math gets done on paper. So we put the tutor where the paper is.
Most math apps put kids in front of a tablet. Koda does the opposite. The pencil and the notebook stay. The screen time doesn't follow.
Hand. Pencil. Worksheet.
Your child writes the way kids have written math forever — on paper, with a pencil, with their full hand in the work.
Tap. Drag. Tap.
Most math apps replace the page with a screen. Kids learn the app, not the math. And the screen time piles up.
Your child picks the voice and the look.
Pick a base — robot, bear, or cat from the start; fox unlocks at level 3, alien at level 5. Pick a voice. Two color slots. Hair, outfit, accessory, companion. As your child earns XP, the avatar adds layers.
Robot, plain outfit.
New colors. A small companion shows up.
New look. A second companion.
Full kit. Backstory chapter opens.

One voice. Three modes. Zero pet names.
Koda is a single character, not a cast. What shifts between modes is the pace and the register — not the personality. And there's a list of things Koda will never say, enforced by a linter before the audio is ever rendered.
- LearningWorking on a new idea12 words per sentence, max
"Look at the ones column. What does 12 minus 7 give you?"
- PracticeDrilling something already met18 words per sentence, max
"You've done this kind before — keep the same setup, line up the columns, and let me know when you've got it."
- ExamQuiet during the testSilent — no hints, no voice
(Koda doesn't speak in exam mode. The walk-back happens after the timer.)
Words Koda doesn't use
A voice linter reads every line before it's spoken. Pet names, minimizing pacifiers, and ALL-CAPS celebrations are caught and rewritten. Your child gets directness — never condescension.
- sweetie
- honey
- buddy
- champ
- kiddo
- good boy / good girl
- smart cookie
- little genius
- silly goose
- don't worry
- it's okay
- it's fine
- no big deal
- no worries
Three worlds. Five levels each. One boss problem at the end of every level.
Math gets its own adventure track. Each world is a slow climb through a topic; new levels open as your child works; boss problems are the moment the topic snaps into place. Reading, spelling, science, and PE focus warmups have their own progression structures — different rhythms for different subjects. All of them earn XP toward your child's avatar.

When your child gets stuck, Koda has a short explainer video for that.
188 short math explainer videos ship with Koda, drawing on five teaching angles — blocks, number line, grid, standard algorithm, word problem. Up to three angles per topic today; software updates add more. Your child picks the one that clicks.
- Concrete: base-ten blocks
- Linear: number line
- Area: hundreds grid
- Symbolic: standard algorithm
- Story: a word problem
- Whichever angle clicks for your child is the one Koda offers next.
Accommodations are first-class — not an add-on.
Set the support flags during enrollment and Koda picks safe defaults. You can change anything in the parent portal.
Pick focus chunks from 5 to 25 minutes (10 default); when the timer ends, Koda offers a short break activity — stretch, breath, or doodle. Then a soft start back. PE focus warmups (short executive-function exercises) are a separate subject that ships with starter content.
Math homework with ADHD →Longer focus chunks (15 minutes) for slower processing. Effort-based XP rewards the careful path. The catalog has a visual angle for most topics, available via the hint ladder. (Default-to-learning-mode and exam-disabled wiring, plus a concrete-first preference, arrive in software updates.)
What dyscalculia actually is →Dyslexia-friendly font on by default. UI animations slow to 75% so visuals are easier to track. Reading load drops without the tutor changing.
Per-profile volume slider. Shorter focus chunks (10 minutes default). Set once, applied every session. (Animations-off and celebration-intensity dials — and the corresponding runtime hookup — arrive in a software update.)
Toggle the dysgraphia flag at enrollment and the rest of the tutor's defaults (focus chunks, animations, celebration intensity) play together with the other flags. Voice answers — an alternative to writing on the worksheet — arrive in a software update; typed input is already how today's session takes the answer.
Camera frames never leave the device.
The device in your home does the looking and the thinking. Nothing leaves the device unless you ask it to. No cloud LLM at runtime.
Reasoning runs locally on the device — no cloud round-trip.
Video frames are not stored or transmitted off the device.
Delete a profile and everything cascades. Single switch, no support ticket.
Why we built Koda.
Most math apps want kids to look at a tablet. Koda does the opposite: the pencil and the paper stay where they've always been, and a small machine on the kitchen counter watches the work and asks the next question.
We're building it for the kids most ed-tech treats as edge cases — kids with ADHD, dyscalculia, dyslexia, dysgraphia, autism. Their accommodations are first-class settings here, not an afterthought.
And we made one decision early that we won't walk back: every frame the cameras see, every word the tutor says, every problem your child works on, stays on the device in your home. No cloud. No data brokers. Nothing leaves the device. We think that's the only honest way to put cameras in front of a child.
