Grading and review
AI grades first. You set the score.
Students write on paper. You photograph or scan their scripts and upload them. AI grades by question type and gives a reason for every scoring point, and you review, adjust and confirm question by question. When grading is done, you get a score sheet and a mistake analysis report for each student, and class review starts from the same real grading data.

Script intake with a confirmation step
Upload scripts as ZIP files, folders, PDFs or photos. By default one file is one student; you can also merge files by name and page number or by folder. Before you can submit, the confirmation step makes you resolve merged multi-page scripts, loose images, page order and duplicate names.
Grading by question type
For multiple choice, the model reads the chosen option and code compares it with the key. Fill-in-the-blank answers are accepted if they are equivalent in simplest form. Worked solutions are first checked against the reference approach, and an answer with no working gets no method marks. A solution that takes a different route gets a provisional score and a flag, and you can run a deep analysis on it.
Scoring explanations and approaches
Each scoring point is tagged as fully correct, a correct minor skip, a factual or calculation error, or a logical gap. Solutions outside the reference approaches are grouped, and once you accept a new approach, matching answers are graded again.
Grade one question at a time from the keyboard
Go through one question across every student. Press Enter to confirm and jump to the next ungraded script. You can confirm high-confidence AI scores in one batch, and any score you change is saved automatically.
Mistake analysis reports and score export
Each student gets a report with one chapter per question where they lost points, going from a review of their attempt to a full solution and how to correct it. You can edit a report and export it on its own or as a batch, as PDF, Word or Markdown. The score sheet exports as CSV.
Personal papers with QR codes, and answer sheets
Generate personal PDF and Word papers from a class roster, each with an identity code. Scanned scripts are matched to students automatically, and grading starts for the batch after you check them on the confirmation screen. With answer sheets generated in OneAI, answers are located by the regions on the sheet, and code reads multiple-choice bubbles.

Who it is for
Subject teachers who grade weekly quizzes and monthly exams, and homeroom teachers and competition coaches who give each student feedback on their mistakes.
