How to grade papers with AI is a sequence you can repeat on the next stack. Prepare the test and the answer key, or the rubric you already mark with. Upload both. Photograph the student papers. Graider marks each paper against that key. You review and override any mark you would explain differently. You open every Low confidence badge on a hard-to-read answer. You toggle feedback on or off. You keep the pen. You hand the work back as a PDF or an email.
Graider is the AI red pen for paper grading, a product of DM Liquidity LLC. Teachers upload a test and answer key, photograph the stack, and Graider marks against their own rubric or key. The public site is graider.org. Everyday paper tests run through AI test grading. AI grading for teachers here means your key leads, and AI paper grading applies that key to the photographs before you review. Your key stays the source of truth through handback.
Your key. Their papers. You review. You keep the pen.
Start with the paper students will sit and the standard you would defend if a student asked about a mark. The test holds the questions and the point values. The answer key holds the responses you accept, including every equivalent and the partial credit: the condition, the points, and a short example. The rubric holds the marking language around that key: which method counts, what a complete response includes, and which mistakes you comment on every time.
Write one question the way a second reader could follow. Question 3 is worth 4 points: name the cause, and give one piece of evidence. Two phrasings earn 2 points for the cause. Evidence from a sentence you listed earns the other 2. A correct cause with no evidence earns 2, with a comment that says what is missing.
Some items belong on a fixed key: multiple choice, a date, a term, a final number. Some items belong on a rubric: an essay, a lab conclusion, method marks. One paper can use both. Answer key grading vs rubric is the guide for which document should drive each question. Bring both when the paper needs both. Before you upload, name which unit must appear, whether a later part may follow an earlier number, and which method you accept.
A labeled sketch, a graph, or a drawing is yours to score. Graider does not read or score diagrams, graphs, or drawings. A written label or a written value next to that drawing stays on the key with the other written answers. If question 5 is a sketch, note that you will set that score yourself.
Upload the test and the answer key you already use. If the rubric lives on its own sheet, upload that sheet with the key. Then check each question number, the points, and the accepted response. Add an equivalent you forgot. Fix a point value that does not match the test students sat. On question 3, both cause phrasings should be on the row, and the missing-evidence line should show 2 points plus the comment. The first pass follows the rows that are actually there.
Photograph every page a student used, including the back when the answer continues there. Keep one student's pages together. The full sheet should be in frame, with the name or identifier your roster expects visible, and the writing readable. Graider matches pages to students on your roster. Confirm that match, including a second page. When a page is too faint or too cropped to read, photograph it again before you rely on the mark. You grade papers with AI from those pictures and from the key you uploaded. Photo tips for a full stack are in how to grade papers with photos.
After the pages are matched, Graider marks each paper against your own answer key and rubric. A line that matches a row you wrote receives the points on that row. On question 3, either accepted cause plus evidence from a sentence you listed earns 4. A correct cause and no evidence earns the 2 points on that line, with the comment you already wrote. The same accepted answer earns the same points on each paper where it appears. You still read the result. A mark you would explain differently is a mark you override. You keep the pen.
Review is your step. Open a paper and read the mark next to the row it came from. When the line matches the key and you agree, keep those points. When your judgment and the first pass disagree, change the points. Edit the comment so it is the sentence you would write in the margin, in your own words.
Then open every Low confidence badge. It is the flag on a hard-to-read answer. Open the photograph, compare the line with your key, and override the score when the page and the first pass disagree. That badge is the only flag. A hard-to-read cause on question 3 is one to open. Set the sketch on question 5 yourself, because Graider does not read or score diagrams, graphs, or drawings. When the same split shows up on several papers, keep the points that match the row and override the rest.
Toggle feedback before anyone else sees a comment. Turn comments on when they should go home with the score, and leave them off when the score is enough. The missing-evidence comment on question 3 can go home. A comment you plan to teach aloud can stay off. The words a student reads are the words you kept.
Hand each paper back as a PDF or an email. The PDF names the test and the student. When you include the score, it shows points earned out of points possible, for the paper and for each question. Each question lists the prompt and the student's answer as text. When you include feedback, the comment you kept sits with that question. You can leave the score off, or leave the feedback off, before the file goes out. Preview the file, then download it or share it.
When you release grades, a student with an email address on the roster gets a message that the grade is ready, with a link to the marks and the feedback you left on. Release waits until you send it. Hand back graded papers digitally covers one file per student. You keep the pen until that file goes out.
Upload the test and your answer key or rubric, photograph the papers, and let Graider mark against that key. Then review, override, check any Low confidence badge, toggle feedback, and hand work back as a PDF or an email.
You bring the key. Graider marks the photographs against it. You review the marks and choose which comments students see.
