Remove handwritten answers from worksheets and exams
Reuse a worksheet, quiz, or exam by erasing the answers a student wrote — questions, diagrams, and equations stay exactly as printed.

Made for teachers and students who reuse materials
A completed worksheet is usually a printed set of questions plus whatever a student wrote in the blanks. This tool separates the two: the printed questions, instructions, equations, and diagrams are left untouched, while everything written by hand — numeric answers, short responses, work shown for a calculation, circled multiple-choice letters, checkmarks, and similar grading marks — is detected and erased.
Handwriting over equations and diagrams
Math and science worksheets often have handwritten work crowded right up against printed equations or diagrams — a circled answer next to a printed formula, or a note scribbled beside a labeled diagram. The detection step is built to draw many small, tight boxes around individual handwritten marks rather than one big box over a whole area, specifically so it doesn't take the printed equation or diagram down with it. See how it works for the detail on why that matters.
One honest limit
If an answer is written directly on top of printed text — actually covering it with ink — that printed content is not recoverable from a single image; the tool reconstructs the area from the surrounding background rather than guessing at what was underneath. This mostly comes up with answers written on blank lines or in open space, which is the common case and works cleanly.
FAQ
Questions about this
Can it remove grading marks like checkmarks and circled scores?
Yes. Checkmarks, circles, X marks, and similar grading marks are treated as handwriting and removed the same way as written answers.
What happens where an answer was written directly on a blank line?
The handwritten strokes are removed and the area is reconstructed from the surrounding paper, so you get back an empty answer line — the printed line itself (if it's a printed rule) is preserved; only the ink on top of it is erased.
Will it change the questions, equations, or diagrams?
No. The detection model is specifically instructed to draw tight boxes only around handwritten marks and never around printed content, even when a handwritten answer sits close to a printed equation or diagram.
