FOR READING INTERVENTIONISTS AND LITERACY SPECIALISTS
The first system that can see
how a child readsThe first system that can see how a child reads
See precisely how each child is learning to read, where they are getting stuck, and what they need most next. OpenBook creates the learning experience live, response by response.

Same mistake. Different cause.
Different next step.Same mistake. Different cause. Different next step.
Two children read ship as sip.
On the surface, it is the same error. Underneath, something very different may be happening.
The other may know the sound, but lose it when blending the word.
Other systems see the same wrong answer. OpenBook models what it means for this learner.
A skilled reading interventionist knows the response alone is not enough. OpenBook carries forward the relevant patterns the child has shown over time, so the same visible error can lead to a different next step.
BUILT FOR READING INTERVENTIONISTS
Powerful under the hood.
Simple in the session.Powerful under the hood. Simple in the session.
OpenBook continuously models each learner and turns that complexity into clear priorities and responsive practice. Your expertise stays at the center.
See the pattern behind the mistake
Know what is secure, where learning is breaking down, and how those patterns are changing.
Know what matters most next
See the highest-priority skill or sub-skill to target, without piecing it together from scores, notes, and memory.
Carry every learner forward
Every attempt adds context, so each session starts with a clearer understanding of the learner.
THE MISSING INTELLIGENCE LAYER IN LITERACY
From measuring reading
to modeling itFrom measuring reading to modeling it
Other reading systems measure what is visible on the surface. They track a child’s scores across preset units, but do not carry forward a continuously updated model of how that child is actually learning.
That evolving understanding is at the heart of expert reading intervention. Interventionists continually refine their mental model of the learner, identify what matters most next, and shape instruction around it.

MEET READING STATE™
A new level of precision
in reading interventionA new level of precision in reading intervention
Reading State™ is a high-resolution, continuously updated model of how each child is learning across foundational reading and spelling skills.

Signals accumulatingModel resolvingInstruction changing
It captures fine-grained signal at the level where reading actually develops: sounds, letters, word parts, sub-skills, responses, hesitations, errors, and support.
It shows what is secure, what is still developing, where learning is breaking down, and how those patterns are changing over time.

READING STATE IN ACTION
The first real-time closed loop

The breakthrough is not just the model.
It's the response.
Every attempt updates the child’s Reading State™. OpenBook captures instruction-grade signal from the learner at the word-part level, then uses that live model to determine what the child needs most next and create it in real time.

GROUNDED IN THE SCIENCE OF READING
Make structured literacy easier
to deliver with precisionMake structured literacy easier to deliver with precision
OpenBook is designed around the evidence-based foundations of reading and spelling, including phonemic awareness, phoneme-grapheme mapping, blending, segmenting, decoding, encoding, and orthographic mapping.
It handles the complexity of tailoring those foundations to each child’s evolving needs, turning a continuously changing learner model into clear priorities and responsive practice.
That makes structured literacy easier to deliver with precision for each learner, without adding more data to decipher or more planning to manage.
PRECISE PRACTICE AT HOME
Help move reading forward
at homeHelp move reading forward at home
OpenBook uses each child’s continuously updated Reading State™ to shape short, focused practice around what they need most next.
It determines what the child should practice, responds as they learn, and updates their Reading State™ with every attempt.
Families do not need specialized literacy knowledge or strong English proficiency. OpenBook guides the session and handles the instructional decisions, so caregivers can support learning with confidence.
When a child is also working with a reading interventionist, the same understanding can carry across settings.
OpenBook guides the practice, so families can help move reading forward at home.
