How CRATOR works.
Five steps from a folder of scans to results you can hand out. These are real screens from the app, with made-up demo data.
-
1
Pick your sheet
Choose the template for the sheet you printed, or design your own in the same app.

-
2
Point to your scans
Select the folder your scanner saved to. CRATOR finds every sheet inside it.

-
3
Let it read
It reads bubbles and barcodes, and its AI reads handwritten numbers, on your computer. Check the flags before you share your results.

-
4
Check what it flags
Erased, double or unclear marks are flagged. Look at the scan, keep the right answer, done.

-
5
Share the results
Add the answer key once. Marks, ranks and report cards follow in Excel and PDF.
