Nice work on the multiplication. Try one a step further: if 6 × 7 = 42, what's 6 × 8 — without multiplying it out?
Easy. It's 6 × 7 + one more 6 — 42 + 6 = 48.

That's exactly the move. You just used the distributive property without me having to teach it. Let's push higher.

How it works

Designed around how a child actually learns.

Not a textbook in chat clothing. Not a video library with quizzes bolted on. A tutor who knows where your child is and meets them precisely there — every subject, every day.

STEP 01

Precision placement

A short adaptive conversation per subject narrows in on the exact edge of what your child knows. No grades. No pressure. Day one, every subject is already meeting them where they actually are.

STEP 02

Lessons in your child's voice

Every lesson opens with a hook, walks through deep teaching with worked examples and the misconceptions other kids hit. The tutor talks like a smart older sibling — never a textbook. Each kid hears the same lesson in a different register.

STEP 03

Mastery, verified — then preserved

Calibrated probes confirm real understanding instead of guessing. Mastered material flows into a spaced-repetition queue so it never quietly fades. You see real progress, not a checklist.

Features

Everything textbooks can't.

Pick any traditional curriculum. Now imagine it with a tutor who actually knows your child, real depth on every concept, and retention engineered into the calendar — not hoped for.

🎯

Precision placement

A short adaptive conversation per subject finds the exact edge of what your child knows in five to ten questions. You start on day one at the right place — not the grade printed on a birthday card.

📚

Depth most curricula skip

Every lesson: a hook, deep teaching, worked examples, the misconceptions other kids hit, 8–12 practice problems, and real-world application — not a glossary page and a quiz.

🎓

A tutor per child

Phase-aware teaching: present, check, then assess. The voice tunes itself to age — playful for the five-year-old, smart-friend for the teen. Every child gets a register they recognize.

Verified mastery

Calibrated probe banks per lesson. End-of-unit tests fire automatically every 5 mastered lessons — mix of multiple choice, short answer, spoken, and a graded essay. Real mastery, not vibes.

🔁

Engineered retention

Mastered material re-surfaces at 1, 3, 7, 21, and 60 days. Spaced repetition is the only reason humans remember anything long-term. Built in, not bolted on.

🎮

Earned motivation

XP, streaks, badges, mini-games tied to real progress — not screen time. Kids ask to play.

🌳

Screen-free lessons

Outdoor and indoor activities that tie back to the day's curriculum — customized to your yard, climate, household supplies, and kids' ages. Learning that ends at the door.

👨‍👩‍👧‍👦

Whole-household view

One parent dashboard for every child. PIN-protected per kid. Live progress, today's activity, per-subject placement — all in one place. Built for families with more than one learner.

Subjects

Twelve subjects. Kindergarten through college.

Core academics plus the electives most curricula skip — finance, cooking, music, visual art, mechanics, apothecary, speech & debate. Italian and Russian language tracks coming soon.

🇮🇹

Italian Coming soon

Listening, speaking, reading, writing — with native voice audio.

🇷🇺

Russian Coming soon

Cyrillic alphabet, phonetics, conversation — with native voice audio.

The depth standard

A kid who reads our lesson knows more than a kid who read the textbook.

Every lesson includes a hook, multi-section teaching, 3–5 worked examples, the most common misconceptions explicitly addressed, 8–12 practice problems with full solutions, real-world application, and extensions for kids who want to go deeper. That's the floor — not the ceiling.

Pricing

$20 per kid. Per month. That's it.

Same per-kid price as IXL — but with a tutor that actually teaches instead of just drilling. Every subject, K-12, included.

FAQ

Real questions, real answers.

Khan Academy is video-first; pacing is the same for every kid. Outschool is class-based, scheduled, and depends on the live teacher's quality. IXL is drill-and-grade — no real teaching. Cullinan Academy places your child precisely, teaches in their voice with real depth, verifies mastery with calibrated probes, and schedules retention into the calendar. A full curriculum, not a supplement.

Kindergarten through college. The placement system runs adaptively across all grades, so a 9-year-old who's secretly already at 7th-grade math gets placed where they actually are — not where their birthday says they should be.

No. The tutor is always available, 24/7, and lessons are self-paced. There's no schedule, no waiting, no one to disappoint. Parents see everything via the dashboard.

Yes. One parent dashboard, every kid has their own profile, PIN, progress, and assignments. $20/month per kid — same per-kid pricing as IXL but with a tutor that teaches instead of just drilling.

Yes — and per kid. The same lesson is delivered with completely different voice and pacing depending on age. Playful for the 5-year-old. Smart-older-sibling for the teen. No condescension at either end.

There's a built-in screen-free activities engine that generates outdoor and indoor activities tied to current lessons, customized to your yard, climate, available materials, and siblings. Screens aren't the goal — learning is.

Yes. We're COPPA-compliant: explicit parental consent at signup, only the minimum data needed (first name, age, grade, lesson answers), never sold or used for ad targeting or model training. Parents can review, export, or permanently delete any child's data from the account page.

$20 per kid per month, or $200/kid/year (save 17%) — same per-kid price as IXL. 1 kid = $20/mo, 3 kids = $60/mo, 5 kids = $100/mo. 14-day free trial. Cancel anytime from the Stripe customer portal.
