Eedi’s infrastructure and assessment tools have been built to address global numeracy poverty. Used by teachers and students across four continents our tools are delivered in partnership with governments, not-for-profit organisations, edtech companies and frontier AI models.
The Diagnostic Engine is our AI-powered learning infrastructure. It sits at the heart of everything we design, research, build and implement. The Diagnostic Engine powers our assessment tools, including DQR and Eedi Tutor, and integrates with third party learning tools and LLMs.
Built on the same expert-authored Diagnostic Questions that drive our Diagnostic Engine, DQR is a low-tech, quiz-based tool that turns a single smartphone into a classroom-wide diagnosis and assessment solution.
Eedi Tutor is a deliberately constrained AI maths tutor that activates only after a specific error is made. It uses structured Socratic dialogue, grounded in the misconception diagnosis of our Diagnostic Engine, to help learners think their own way forward.
"Everyone deserves a quality education. Just as medicine was transformed when it moved from observing symptoms to diagnosing root causes, education must move from tracking wrong answers to identifying misconceptions and resolving them.
We built Eedi to identify not just that a student is struggling, but why - using misconceptions to turn flat assessment data into precision learning, and giving one billion kids the agency to thrive in a rapidly changing world."
— Ben Caulfield, CEO

Our Evidence team measures real-world impact. It designs and runs rapid tests and longitudinal gold-standard Randomised Controlled Trials (RCTs) with the goal of demonstrating real and measurable improvements in learning outcomes for students.
Our Data Science team builds the sophisticated models that power our Diagnostic Engine. They translate academic research and real-world data into the predictive, practical AI that underpins our product ecosystem and end-user products like Eedi Tutor and DQR.
Our Learning Design team of experienced former teachers is responsible for the integrity of Eedi's diagnostic questions and misconception library, ensuring every question, construct, distractor and explanation is age-appropriate and evidence-informed.
Eedi partners with the education industry's leading research labs, LLMs and funders
Eedi has earned a gold certificate from EDUEvidence for demonstrating statistically significant impact through independently verified randomised controlled trials. We have also been named one of HundrED's most impactful and scalable K-12 innovations of 2026.
