Any paper format
Grade on the exam itself, or on any answer sheet
Students circle answers on the question paper, or fill a separate bubble sheet. Snap AI reads both — no fixed template, no optical scanner.
Answer sheets
Grade every bubble-sheet layout
OMR cards, answer sheets, and local bubble forms — 20, 24, 40 items, or more. Any grid of filled bubbles works. No need to reprint one official form.
3-step workflow
From a photo of the exam students already took to a complete score sheet
Photograph the paper students already filled in. No extra answer sheets to print, no optical scanners. AI grades each question on that same exam paper.
Capture & upload
Photograph the exam students already used
Use your phone to photograph a stack of completed exams, or upload images/PDF. Grade the paper students already wrote on — no extra bubble sheets, no reprinting. AI reads the name, candidate number, class, and exam code already printed on the page.
Step 01 / 03
Scan & auto-grade
AI grades each question on that same paper
AI looks at the student's pencil or pen marks on the original exam, matches them to the key for that exam code, marks a red V for correct items, crosses incorrect choices, circles the official key, and scores each question. No separate answer form to scan.
Step 02 / 03
Review & export
Review the original paper image and export CSV/Excel
Teachers review graded work on the original exam photo, just like hand-marked papers. Unclear marks can be fixed in one click, then export a roster (name, exam code, score, details) to share with parents.

- Computer-vision AI
Reads pencil marks and hand circles
AI detects answers students circled in pencil or pen on the exam they already took — including faint marks, off-center circles, and eraser smudges. No extra answer sheet required.

Automatic grading with AI
Automatically marks a V for correct answers, crosses wrong choices, and circles the official key. It also scores each question in detail and exports the grade sheet directly.

Frequently asked questions
AI grading, manual review, CSV export, and current access.
Most grading apps still need a printed bubble sheet or an optical scanner. Snap AI grades the exam paper students already filled in. Photograph that paper, add the answer key, and the system marks each question and returns a complete score — no extra forms, no reprinting.
Yes. After a batch finishes, you mark ungraded items Correct or Incorrect and save. The system only recalculates the score from the locked weights — it does not call AI again. Changing score weights on the profile does not alter old batches.
Export CSV with columns Name, Exam code, Score, Notes (names of ungraded questions, comma-separated).
