Theo

The platform applies artificial intelligence to automate tasks commonly carried out by classroom teachers, including marking student submissions, generating lesson plans, and adapting learning content to individual pupil needs. According to the service's website, the system is designed to adapt to a teacher's individual style and preferences over time, with the stated aim of reducing the time spent on routine administrative and preparation tasks each week.

Theo is delivered as a web-based application accessible through a browser at trytheo.org. Typical use cases include assignment grading, curriculum and lesson planning, and the creation of differentiated learning resources for pupils with varying abilities or requirements.

The tool is aimed at teachers and educators seeking to reduce manual workload associated with assessment, planning, and content personalisation.
