ExamGPT, developed by the team at Excelas.ai, is a state-of-the-art, specialised AI marking engine purpose-built to address the global crisis in teacher workload and assessment accuracy. Unlike general-purpose Large Language Models (LLMs) that struggle with technical nuances and non-linear reasoning, ExamGPT is a "Vertical AI" engineered specifically to grade handwritten STEM mock exams with examiner-level precision.

Our proprietary technology excels at deciphering messy student handwriting and analysing complex mathematical and scientific logic to identify hidden "Logic Gaps" that traditional marking often misses. By integrating seamlessly into the existing school workflow, ExamGPT transforms the standard two-week marking cycle into a rapid 24-hour diagnostic window. It provides students and educators with a "diagnostic biopsy" of performance, delivering granular feedback mapped directly to national exam standards and specific Assessment Objectives. Supported by Google and AWS, and born out of the LSE and UCL ecosystems, ExamGPT is a data-driven infrastructure designed to power the success flywheel and eliminate teacher burnout.

• Reclaim Marking Time: Automates the grading of handwritten papers, reducing teacher workload by up to 90% and eliminating the "marking mountain."
• The "Diagnostic Biopsy": Moves beyond a simple grade to provide granular feedback on specific Assessment Objectives (AOs), Method marking and hidden misconceptions.
• Instant Data-Driven Insights: Generates immediate departmental reports, allowing school leaders to identify whole-class gaps and adjust teaching strategies in real-time.
• Accelerated Student Growth: Provides students with personalised, high-fidelity feedback within 24 hours of their mock, closing the learning loop while the material is still fresh.
• Total Moderation Consistency: Ensures 100% marking accuracy across entire year groups, removing the friction and bias of internal moderation.
