How it works

An AI tutor that learns your child, session by session.

PrimerBot is designed to keep a running picture of every reading skill, find the gaps, and choose what to teach next, using lessons built and reviewed by reading experts.

The AI tutor

What the AI does for your child.

Every answer tells PrimerBot something new. It is designed to analyze each attempt, find the gaps in what your child knows, and steer every session toward the skills they need next, so their time goes where it helps most.

  1. Learns your child

    Builds a running picture of every reading skill, from the very first session.

  2. Finds the gaps

    Spots what's solid, what's shaky, and what's missing, and keeps checking as your child grows.

  3. Adapts every session

    Chooses what to teach next, how to explain it, and how fast to move.

  4. Checks for real

    Steps back and asks for a brand-new word with no hints, so progress means your child can do it alone.

  5. Remembers

    Comes back days later to make sure each skill stuck, and picks up where your child left off.

Every session, PrimerBot adjusts the path to fill the gaps it finds.

Experts decide what PrimerBot can teach. PrimerBot decides what your child needs next, from lessons and stories built and reviewed by reading experts.

The tutoring loop

How PrimerBot tutors, every session.

Finds the starting point.

In the first session, short, playful checks are designed to find what your child already knows, so nobody has to guess a reading level.

Design concept, in development

Built on what reading research supports.

The U.S. Institute of Education Sciences reviewed the research on teaching foundational reading skills in grades K–3.1 What PrimerBot teaches is built around three of its recommendations, and reading experts review every lesson before children use it.

Connect sounds to letters.

Develop awareness of the sounds in speech and how they link to letters.

Strong evidence

Decode words.

Teach children to decode words and analyze word parts.

Strong evidence

Read real text every day.

Ensure children read connected text daily for accuracy, fluency, and comprehension.

Moderate evidence

These practices are well supported by research. We'll test PrimerBot itself with families and report what we find.

A patient tutor with good manners.

PrimerBot is warm, patient, and honest about what it is.

It says:

Let's read a little.

Your turn.

I didn't quite hear that. Let's try once more.

Let's try it a new way.

All done for now.

It never says:

"I missed you." · "I'm your best friend." · "Don't go." · Anything that asks for personal information.

Every child picks a look. The face stays the same, and looks are never earned or sold.
