Rubrical is the AI assistant that gives teachers their evenings back by cutting marking time in half while keeping every final decision (and every student’s learning) in their hands.

The platform was created by OpenKit and backed by the UK Department for Education’s £1 million AI teacher-tools programme. It is designed to save teachers time while maintaining full professional control and raising feedback quality.

Who it’s for:
• Teachers in schools wanting to reduce workload
• Heads of Department who need consistent, standards-aligned marking  
• Trusts looking to improve retention

Core workflow  
1. Connect – 5-minute setup with optional connection to Google Classroom or Microsoft Teams  
2. Generate – AI creates curriculum-aligned rubrics from any exam question or assignment  
3. Submit – Students hand in typed or handwritten work (OCR digitises handwriting)  
4. Mark – AI suggests marks and detailed feedback; teacher reviews and approves  
5. Return – Grades and personalised comments are sent back to the student

Key benefits  
• 50% less time spent on marking assessment  
• 92% marking accuracy 
• Curriculum-aligned rubrics and grade boundaries
• Built-in analytics that surface class-wide strengths and gaps  
• GDPR-compliant, ISO 27001 and Cyber Essentials certified

Teacher control  
Every AI suggestion can be accepted, edited, or overridden. Voice commands, keyboard shortcuts, and batch actions make the review step even faster.

Impact to date (DfE pilot)  
• Hundreds of hours saved per department each term  
• 95 % teacher satisfaction  
• Consistent, high-quality feedback delivered to every student, not just when the teacher has energy left
