Fact sheet
Classi at a glance
Classi (classi.app) is an AI grading platform for schools. It reads handwritten and digital answer sheets, marks them against the school's own marking scheme, writes feedback for each student, and shows teachers where the class is struggling. A teacher reviews every mark before it is released.
Grading
| What it grades | Handwritten answer sheets (PDF scans or phone photos) and digitally submitted answers |
|---|---|
| Question types | Multiple choice, assertion–reason, matching, ordering, numerical, short answer, structured multi-part, extended writing and essays, diagram and practical questions |
| Marking method | Point-by-point positive marking for structured answers; best-fit markband marking for answers with level descriptors; multiple choice checked directly against the key |
| Marking scheme | The school's own. Classi can draft a model answer and marking points for a test that has none, for the teacher to edit |
| Boards | CBSE, ICSE and ISC, state boards, IB, Cambridge IGCSE, AS and A Level, and school-internal tests |
| Subjects | Any subject with a written marking scheme |
| Languages | English, Hindi and other languages. Feedback is written in the language of the question |
| Board-specific handling | Internal-choice and "attempt any" questions; half marks only where the scheme allows; whole marks for IB and Cambridge |
| Speed | Full class sets graded in under five minutes on average at The Riverside School; a class of 300 takes no longer than a class of 30 |
| Teacher control | Every mark is a proposal until a teacher approves it. Illegible or unreadable answers are flagged for the teacher |
| Feedback | Specific written feedback for every student on every answer |
