What Eedi does

Eedi Labs is a UK-based applied research organization founded in 2015 that builds AI-powered diagnostic infrastructure for mathematics education. Its core asset is a diagnostic engine refined over nearly a decade of classroom use across more than one billion learner interactions, comprising a library of over 60,000 multiple-choice diagnostic questions where each incorrect distractor is mapped to a specific named misconception. This engine is paired with proprietary Knowledge Tracing (KT) models — including a compact 0.73M-parameter LLM KT that achieves 72.8% accuracy on student response prediction versus 58.6% for GPT-4o-mini — enabling precise, real-time identification of what each student misunderstands and why.

The company operates through a tiered product surface: Eedi School (the free testbed platform for classrooms, homework, and RCTs); the DQR (Diagnostic Question Response) app, which delivers whole-class formative assessment using only a teacher's device; the Constrained AI Tutor, a human-in-the-loop AI tutoring system that activates only when a student answers a diagnostic check-in incorrectly and is bounded to the specific construct being learned; and Eedi Inside, an OEM/white-label program that embeds the diagnostic engine inside third-party publisher and AI platforms. Eedi School Plus, a £54/student/year subscription for parents and students, adds chat-based human tutor support.

Eedi monetizes through a hybrid model combining freemium access for schools and teachers, direct parent/student subscriptions, and licensing of the diagnostic engine to publishers (notably Imagine Learning's Imagine IM US math curriculum, back-to-school 2026) and frontier AI labs (Google DeepMind's LearnLM research). It primarily serves K-12 secondary schools (UK Years 7-10, US grades 6-8), with a stated mission to improve learning outcomes for one billion children by 2030. The company employs approximately 40 people on a fully remote UK basis and is currently expanding into the US market via the Imagine Learning distribution deal and an Accelerate-funded RCT.

Core offering

Eedi builds and operates an AI-powered diagnostic engine for mathematics that identifies and resolves individual student misconceptions in real time using a library of 60,000+ mapped questions and proprietary Knowledge Tracing models. The company delivers this through three product lines: Eedi School (free classroom and homework platform for teachers, students, and parents), Eedi Inside (OEM/embedded licensing of the diagnostic engine for publishers, frontier model providers, and learning platforms), and the Constrained AI Tutor (human-in-the-loop tutoring that activates when diagnostic checks are failed).

Product overview

Eedi is an applied research organization that operates primarily through its Eedi School platform and the Eedi Diagnostic Engine as its core infrastructure. The diagnostic engine, built on over a decade of data and one billion learner interactions, identifies student misconceptions in real time through a library of 60,000+ questions. Eedi Inside extends this intelligence to third-party publishers and platforms as infrastructure. The Constrained AI Tutor module works within Eedi School to provide targeted intervention when misconceptions are detected. The DQR system enables whole-class diagnostic assessment through teacher devices. The company offers BUILD (infrastructure for partners), TEACH (DQR for teachers), and LEARN (research and tutoring) product lines.

Products and services

• Eedi School A free-to-schools classroom and homework platform powered by Eedi's diagnostic engine, used by teachers to assign diagnostic quizzes, by students to complete them, and by parents to monitor progress. Available to UK and US K-12 schools at no charge.
• Eedi Inside (Diagnostic Engine Intelligence Infrastructure) An OEM/white-label licensing program that embeds Eedi's diagnostic engine as the intelligence layer inside third-party publisher platforms, LLM-powered products, and learning systems. The engine drives efficacy for LLMs, assessment tools, and AI tutoring systems.
• Eedi School Plus (Parent/Student Subscription) Paid annual subscription for parents and students priced at £54 per student per year. Includes unlimited access to chat-based human tutor support and additional AI tutoring features beyond the free school-tier offering.
• Constrained AI Tutor An AI-powered tutoring tool that activates only when a student answers a diagnostic check-in question incorrectly and engages the student in brief text-based conversations to resolve specific mathematical misconceptions before returning them to the lesson. Features human-in-the-loop supervision where human tutors review, edit, or reject every AI-drafted message.
• DQR (Diagnostic Question Recommendation) Classroom Tool A classroom diagnostic tool that enables teachers to gather real-time formative assessment data from an entire class without requiring students to have their own devices. Designed for low-device classrooms and offline-first use cases.

Partnerships

Seven partnerships are on record, tiered core, notable and minor.

• AcceleratecoreStrategic or Co-development Partner · 13 May 2026Eedi was selected as a grantee of Accelerate's 2026-27 Call for Effective Technology (CET) program. Selected from 87 applicants, Eedi will conduct its first US RCT of its constrained AI Tutor in middle school classrooms in two US school districts. The program is designed to generate evidence meeting ESSA Tier 1 certification requirements. This represents Eedi's formal expansion into the US K-12 market.
• Imagine LearningcoreOEM/ Whitelabel/ Licensing Partner · 15 January 2026Imagine Learning and Eedi announced a strategic partnership to integrate Eedi's AI-powered diagnostic engine directly into Imagine Learning's Imagine IM math curriculum for US classrooms. The system launches for back-to-school 2026. Eedi's engine uses over a decade of student learning data to identify student misconceptions in as few as 10 questions, enabling teachers to adjust instruction immediately without additional testing tools. The partnership aims to expand real-time assessment across Imagine Learning's portfolio including ELA and science.
• Google DeepMindcoreStrategic or Co-development Partner · 11 November 2025Eedi partnered with Google DeepMind to conduct exploratory RCTs on human-in-the-loop AI tutoring in UK classrooms. The research found that supervised AI tutoring matches the effectiveness of human tutors. Eedi's diagnostic engine provides the specific misconception signal that turns a generic LLM (LearnLM) into a pedagogically-grounded AI tutor. Supervising tutors approved 74.4% of AI-drafted messages without edits. A second RCT was launched in April 2026 with DeepMind, involving 1,525 students across 10 UK secondary schools.
• WhatWorked EducationcoreStrategic or Co-development Partner · 7 November 2025WhatWorked Education, led by Dr. Wayne Harrison and Professor Steve Higgins, conducted the independent gold-standard RCT evaluating Eedi's impact on 2,901 students across 20 UK schools. This research validated Eedi's effectiveness and formed the basis of the EduEvidence gold efficacy certificate.
• Stanford University (SCALE Initiative)notableStrategic or Co-development PartnerStanford University's SCALE Initiative reviewed over 800 papers on AI in K-12 education and included Eedi's 2025 AI tutor RCT as one of only 20 high-quality causal studies. Stanford's publishing of research notes about the Eedi/Google DeepMind study also increased Eedi's visibility in the academic community.
• Rising AcademiesminorStrategic or Co-development PartnerRising Academies is an innovative education provider operating in Rwanda. Eedi's Simon Woodhead visited Rising Academies' schools during the Global Learning Conference 2026 in Kigali and observed their use of AI tutors (RORI) on mobile phones. Eedi is developing an offline-first version of its DQR app to address data cost concerns raised by Rwandan teachers, working with lessons learned from Rising Academies' experience.
• van der Schaar Lab (University of Cambridge)notableTechnology or IntegrationMihaela van der Schaar's lab at Cambridge is a leading AI for education research lab. Eedi's collaboration with the lab advances AI for human empowerment, making learning more personal and accessible. The partnership contributes to Eedi's research credibility and open science commitment.
