What it was
An AI-powered exam preparation platform for the PLAB (Professional and Linguistic Assessments Board), the pathway international medical graduates take to practise in the UK. Adaptive question generation, AI-assisted revision, personalised weakness targeting.
What happened
Built independently; acquired in 2023.
