Currently piloting with 10 UK secondary schools
Built by educators, for educators.
CredimusAi exists because teachers asked for it. We built it alongside the people who use it - subject leaders, exams officers, and deputies who know exactly what the marking problem costs.
Our Story
Built from inside a trust, not a boardroom.
CredimusAi was built in partnership with a UK multi-academy trust spanning 10 schools. Rated Outstanding by Ofsted, the trust knew exactly what high-quality teaching looked like - and they saw that mock marking season was quietly undermining it.
Subject leaders were spending entire weekends on scripts. Feedback was inconsistent between teachers. Turnaround times meant students received results weeks after the exam, when the learning moment had passed. The trust didn't want a generic EdTech product. They wanted something built specifically for how UK secondary schools actually work.
So they commissioned it. They defined the workflow, wrote the requirements, tested every version, and pushed back when the AI didn't meet the standard. The result is a product that reflects real marking practice - not a demo environment built by people who've never touched an exam script.
