With the answer key
Read and matched
Upload the key and your sheet. Each mark is read off the page and compared against the key, question by question.
Question paper only
Solved in front of you
No key needed. Every question is worked out and the reasoning sits next to the verdict, so you can disagree with it.
How this behaves
Four rules the tool is held to, including the ones that cost it a tidier-looking result.
An unclear mark is never resolved into a guess
It is flagged, cropped out of your own sheet and shown to you. You decide what it says — it is not counted either way until you do.
Derived answers arrive with their working
Where there was no key, the reasoning behind every answer is shown alongside it. A verdict without working is just an assertion.
Nothing is stored
Pages are held in memory while the check runs and discarded when the result comes back. No database, no uploads folder, no history.
Uncertainty is stated, not smoothed over
With questions still outstanding, you get the range your score actually sits in rather than a confident-looking single number.
Ready when your paper is
Photos of the pages are enough. Straight and well lit gives the best read, but anything unclear comes back to you rather than being guessed at.
