Grade handwritten tests with AI
Your students write on paper, as they always have. You scan or photograph the tests, Correxio reads the handwriting and proposes a score against your rubric, which you review before anything is exported.
What Correxio does with your paper tests
Most AI graders need typed or online submissions. Correxio starts from the paper the student actually wrote on, so nothing changes in your classroom: same worksheets, same tests, same conditions.
The AI reads the page itself
It works from the image of each page, not from a separate transcript: crossed-out words, arrows, diagrams, worked calculations and formulas are seen exactly as the student left them on the sheet.
A justified score per criterion
For each criterion in your rubric, the AI proposes points and explains what it read and why it scored it that way. It adds a two-to-three-sentence overall comment, which you can rewrite.
The scan always next to the score
When reviewing, the paper sits on the left and the scores on the right. Click a question and the scan scrolls to where the student answered it, so you check against the original handwriting, not a summary.
Annotations placed on the paper
The AI's remarks are pinned to the scan where they apply, with errors and positive comments told apart. Move, edit or delete them, or draw your own.
Students get their own paper back
The PDF export shows each student's scanned test with its annotations, after a cover page with the score and overall comment. Download the whole class as one ZIP, and the grades as a CSV.
From a stack of paper tests to grades in four steps
The same flow for every subject and grade level, from elementary school to college, as long as the work is written on paper.
Set up your rubric
Enter your own, or upload the test and let the AI draft criteria that you adjust, down to the quarter point.
Scan the papers
One PDF per student, or the whole class in a single PDF split into papers file by file or page by page. No scanner? Scan the QR code on your screen and phone photos go straight into the batch.
Let the AI read
Crooked photos are straightened, the student's name is masked, then the AI reads each paper and proposes scores. Marks left from an earlier, separate grading are ignored.
Review, approve, hand back
Confirm or change every score, then export. Nothing leaves Correxio until you approve it.
Questions about grading handwritten work
How should I scan or photograph a handwritten test?
Lay the sheet flat, use even lighting with no shadow across the page, and frame the whole page including its edges. One page per photo, or PDF scans from a copier if you have one: that gives the most reliable reading. No need for a perfect angle, since a crooked photo is straightened automatically.
What happens with messy or hard-to-read handwriting?
Very poor handwriting or a blurry scan makes reading harder, just as it would for a human grader. That is why each score's justification shows what the AI understood, and why the scan stays on screen beside it: if a passage was misread, you see it and fix the score in seconds.
Which subjects and grade levels does it work for?
Any subject where students write on paper: essays, short answers, languages, history, science, math, from elementary school to college. What matters is your rubric: the AI grades against your criteria, whatever the subject.
Is my students' work kept private?
The student's name is detected and masked before the AI reads the paper, and comes back in your export. Data is hosted in France, and papers are never used to train a model.
How much does it cost to grade a set of paper tests?
Usage is counted per graded page of student work: a double sheet written front and back counts as 4 pages. The test, answer key and rubric are not counted. The free plan includes 30 pages a month, paid plans 250 or 500.
