Optical mark recognition
Photograph the answer sheet.
Read back every answer.
OMR Scanner takes a single photo of a filled bubble sheet, squares it up against its own corner markers, and resolves every question to a marked answer — no flatbed scanner, no manual tally.
Sign-in required — sheets are scored on this server, nothing is shared.
From a phone photo to a graded sheet
Four steps. You only do the first one.
-
01
Upload
Take a photo of the filled sheet, or scan it, and upload it — no special equipment required.
-
02
Align
The engine locates the sheet's four corner markers and corrects for skew, tilt and perspective.
-
03
Detect
Every bubble is measured against the template and resolved to marked, unmarked, or multi-marked.
-
04
Review
Get back the marked-up sheet image next to a question-by-question answer breakdown.
Built for the sheet you actually hand out
No flatbed, no app
A phone photo is enough. Perspective and lighting are corrected after the fact, not before.
A ready 20-question layout
Ships with a working answer-key template, so there is nothing to design before the first upload.
Proof, not just a score
Every result comes with the marked-up image it was read from, so a disputed answer is checkable at a glance.
Signed in, not public
The scanner sits behind one-time-code email login. There is no anonymous upload path.
