Built to Read and
Understand maths

A general OCR model sees ink. TatvaLabs sees the diagram, the expression and the method — and marks each one the way a teacher would.

A student’s handwritten line: the integral from 0 to 2 of 3x squared plus 2x, dx, equals 12. Read shows the same line as TatvaLabs extracts it, in typed maths.

Recognizes maths diagrams
Hand-drawn triangles, graphs and figures, read as geometry.
Reads complex expressions
Fractions, roots and brackets, transcribed as written.
Step-by-step validation
Every line is checked. One slip won't cost the marks after it.
Any correct method counts
Any valid route to the answer is judged on its own working.

Three minutes, one real Class 8 unit test: the sheets go in as scans and come back marked, with every mark tied to the line of working that earned it and a queue of the papers that need a teacher's eye.

Why it matters

Shaping the future of the classroom

Hand over the bundle and get it back marked. Teachers check the marks instead of making them, and put the hours back into lessons.

Every answer is marked step by step against your scheme, so each student sees which line of working earned a mark and which didn’t.

One marking scheme, applied the same way to every sheet, from the first paper in the bundle to the last.
