Features
From a pile of scans to a graded, reviewed paper, without ever rewriting the same remark twice.
Batch upload
Drop in your papers as PDFs or photos, or take them with your phone by scanning a QR code shown on screen. A PDF of the whole class splits into papers, file by file or page by page, and crooked photos are straightened automatically.
A rubric drafted from the exam
Upload the exam statement: while you import the papers, the AI drafts a rubric, question by question. You set the points, down to the quarter point, and spell out what each criterion expects.
Your answer key as a reference
Attach your answer key if you have one: the AI uses it for the expected results, while still grading strictly against your rubric.
Always anonymous
On every paper, the student's name is found and hidden before grading: the AI grades blind. You show the names whenever you like, for the whole batch at once.
A justified score per question
Each paper is read against the rubric you wrote for this specific test, not a generic one for your subject. It gets a score per question with its justification, plus overall feedback.
Annotations on the paper
The AI places its remarks right on the scan, where they belong. Move, edit or delete any annotation, and add your own by hand wherever you want.
Math and code done right
Fractions, exponents, roots and code snippets show in real notation in annotations, justifications and feedback, on screen and in the PDF handed back to the student.
Fast review
Click a question and the paper scrolls to where the student answered it. Adjust a score or a comment, approve the paper, move to the next: nothing is exported without your say-so.
Annotated PDF and CSV export
Export the class's scores as CSV for your gradebook, and each paper as an annotated PDF with a summary page, ready to hand back. The whole batch can also go out as a single ZIP file.
Grading in several languages
Annotations and feedback can be written in English, French, Spanish, German, Italian, Portuguese or Dutch: handy for language classes and international sections.
On computer and phone
Correxio works in the browser and as an Android app: import papers on your phone, review them on a big screen, or the other way round.
