Personalized to passions
Lessons are themed around what your kid actually cares about skateboarding, sea turtles, robotics, art. Engagement isn't a nice-to-have. It's the curriculum.

How Primer Works
How Primer works: five steps for you to set up, five for your student every lesson.
You do these five once.
- Add Your Student. Just a name and how old they are.
- Tell Primer About Them. What they love, where they get stuck, what to master.
- Set the Curriculum. Choose the subjects, then the skills inside them.
- Review the Path. Reorder, skip, or mark units mastered any time.
- Generate the Lessons. See the batch first, or let it keep going.
They do these five every lesson.
- Lesson. Read and listen, with charts, pictures and video.
- Unplugged. Five minutes off screen, plus a worksheet.
- Puzzle. A crossword, so new words are recalled.
- Practice. Five no-pressure questions find the shaky spots.
- Exit Ticket. The real check. It shapes tomorrow's lesson.
It adapts from there. Lessons aren't built weeks ahead. Each one learns from the one before it.

Primer Forgets Nothing
Every lesson, question, and raised hand is kept, per student, and used to decide what comes next.

Why we built this
Education hasn't changed since the 1950s.
One teacher. Thirty students. One pace. One curriculum.
We now have the ability to customize learning for each student based on their goals, their passions, their pace. So why aren't we?
We built Primer for our own children, because every student deserves a school built around who they are and what they want to be.
What makes it different
A teacher that remembers everything.
Every lesson is built from what your student knows, loves and needs next. The system gets sharper with every answer.
Memory across every lesson
A teacher that remembers every question, every missed answer, every breakthrough. Future lessons reinforce what your student got wrong and skip what they already know.
Multiple ways to learn each lesson
Lesson content, off-screen activities, puzzles, practice. Every format reshapes itself around your student so the same idea lands from every angle.
Off-screen breaks, built in
Every lesson includes a hands-on break drawing maps, measuring rooms, building with what's around them. Screens earn their place; they don't replace doing.
Built for every kind of learner
Focused therapy-style lessons plus per-student accommodations dyslexia-friendly type, adjustable size, sentence-level highlights, read-aloud. Designed to feel native, never like a tool for kids who "need help."
Goes as deep as they go
From learning what a map is to working through the limit definition of a derivative. Primer scales from kindergarten foundations to high-school calculus, in one place.
Printable practice
A worksheet with their name on it.
Every lesson comes with a printable worksheet written for one student. It opens with a greeting by name, follows the lesson they just finished, and works in the things they love, whether that is a pan of dog treats in a fractions problem or a robot helper in the corner. The answer key is on the last page, and more are one email to their teacher away.
