ClassGrade — by BlueberryML
Grade any piece of work. Know exactly where every student stands.
ClassGrade connects to a living knowledge space built from multiple curricula and hundreds of thousands of students. Submit student work — handwritten, printed, or spoken — and get back a grade, the learning outcomes it maps to, and the path forward. No setup. No curriculum configuration. Just intelligence.
Access the intelligence. Or build on top of it.
Access the knowledge space
Submit student work. Get intelligence back. ClassGrade grades the work, maps it to learning outcomes, and places the student in a unified knowledge space that spans curricula. You get a precise picture of what the student knows, what's missing, and what to do next.
No student data stored with us. No curriculum to configure. The knowledge space already exists — built from UK National Curriculum, Cambridge, CBSE, Common Core, and more. You just plug in.
Perfect for
Build your own layer
Use the shared knowledge space as a foundation, then extend it. Add your own curriculum, your own assessments, your own proprietary signals. Your extensions live in your infrastructure — fully private, fully yours.
A children's ABC app can plug into the early literacy region and extend it with phonics-specific voice signals. A maths tutoring platform can inherit all the prerequisite relationships already mapped and add its own problem-solving tracking.
Or use ClassGrade as the full platform — exam builder, auto-grading, adaptive learning, teacher tools, parent insights, reporting. Everything deployed and ready.
How it works
Three steps. Any student work. Fully automatic.
Submit
Student work arrives — a scanned exam, a photographed worksheet, a voice recording, a digital response. ClassGrade accepts any format.
Grade & Place
The system grades the work instantly. Handwritten answers are read via OCR. Voice is transcribed and assessed. Every response is mapped to learning outcomes and placed in the knowledge space. Not just a score — a position.
Understand & Act
What does this student know? What's nearby? What's missing? What should they work on next? ClassGrade returns a detailed breakdown — for the student, the teacher, and the parent. The knowledge space computes the optimal path forward.
The full toolkit
Everything you need to assess, understand, and improve.
Exam Builder
Generate curriculum-aligned exams with AI. Six question types — MCQ, fill-in-the-blank, true/false, short answer, reading comprehension, match the following. Review, edit, and print with QR codes for automatic identification.
Auto-Grading
Photo-to-results in seconds. QR alignment, ink detection for multiple choice, AI transcription for written answers. Learning outcomes mapped automatically.
Personalised Learning Paths
Every student gets their own path. The system tracks mastery across learning outcomes and recommends the right next step — not just harder questions, but the right questions, computed from the knowledge space.
Curriculum Intelligence
UK National Curriculum, Cambridge, CBSE, Common Core — already built in. Any additional curriculum onboards in days. Every question, every activity, every report is mapped to learning outcomes.
Reporting
Student, class, or school level. Progress against learning outcomes, gap analysis, and trend data. Automated, real-time, zero admin overhead.
Who it's for
From solo apps to national school networks.
