Intelligent exam preparation,
powered by AI.
We're building the next generation of revision tools. Our platform uses advanced machine learning to understand exam requirements and personalise learning pathways for each student.
Our Technology
Cortex combines state-of-the-art AI with deep understanding of UK examination requirements to deliver personalised learning at scale.
Vision-Language Processing
Our pipeline processes handwritten answers and diagrams using large vision-language models (72B parameters), enabling accurate understanding of student work beyond simple text OCR.
Runs on Modal Labs GPU infrastructure
Knowledge Tracing
Bayesian models track each student's understanding across topics over time, predicting knowledge gaps and optimising revision schedules based on proven learning science.
Based on cognitive learning research
Mark Scheme Analysis
Our semantic engine understands examiner intent by analysing official mark schemes, going beyond keyword matching to identify the specific criteria examiners look for.
Aligned with AQA, Edexcel, OCR specifications
Proprietary Data
We've built a structured database mapping 10+ years of past papers to syllabus requirements, connecting 50,000+ questions by skill dependency rather than just text similarity.
Continuously updated with new papers
Built for the UK education system
Cortex is specifically designed for GCSE and A-Level students, with deep integration into UK exam board requirements and marking standards.
Market Opportunity
Infrastructure
Our serverless architecture is designed for scale and efficiency.
GPU Compute
A100/A10G GPUs via Modal Labs for running 72B parameter vision models with sub-second inference.
Vector Search
High-dimensional embeddings for semantic question retrieval and knowledge graph traversal.
Event-Driven
Serverless processing pipeline that scales automatically with student upload traffic.
