Testimonials

Teachers love it. Principals trust it.

"I used to spend my entire Sunday grading Class 10 physics papers. Now I do 35 sheets in under 20 minutes. The feedback it writes is better than what I had time to write manually."

Rohan Singh

Physics Teacher · Delhi Public School

"As a principal, what sold me was the analytics. I can now see which topics the whole class is struggling with not just after exams, but after every test. That's never been possible before."

Priya Joshi

Principal · St. Mary's ICSE School, Pune

"Parents used to ask me why their child lost marks. Now I just send them the Kelzo report it explains every question, every mark. Parents are happier, and I spend zero time on follow-up calls."

Anjali Mehta

Mathematics Teacher · Kendriya Vidyalaya, Mumbai

FAQ

Common questions.

Yes. Kelzo works for any written answer sheet science, maths, social studies, languages, and more. It supports CBSE, ICSE, and all major state boards. The AI reads the question paper you upload and grades against it, so it adapts to any syllabus automatically.

In our testing with experienced teachers, Kelzo's marks align with teacher marks over 90% of the time on structured questions. For subjective or essay-type answers, we recommend teachers do a quick review of the AI's feedback. Teachers can always override marks directly in the app.

Absolutely. We do not store or use student answer sheets for any purpose other than grading the specific test you submitted. Data is encrypted in transit and at rest. We comply with Indian data protection regulations and can sign a data processing agreement for enterprise schools.

No. Students and parents receive a WhatsApp link. Clicking it opens a mobile-friendly result page in their browser no app download, no account needed. Teachers and school admins use the app and web portal respectively.

Claude is trained on a wide variety of handwriting styles and performs well with typical student handwriting. For particularly illegible answers, the system will indicate low-confidence grading so the teacher can review that question manually. Grading quality improves when sheets are photographed in good lighting on a flat surface.
