The Graider AI red pen marks a paper test while you still decide what each score means. You upload the test and the answer key you already use. You photograph the student papers. Marks land against that key and rubric. You review the stack, toggle the feedback students will see, and keep the pen. Then you hand the work back as a PDF or an email.
A red pen is how you award a point, hold a point, and leave a note the student can use on the next paper. The AI red pen keeps that seat. The stack is the volume. The standard stays the one you wrote on the key.
Graider is the AI red pen for paper grading, a product of DM Liquidity LLC. Everyday quizzes and unit tests follow the same path through AI test grading. The public site is graider.org.
Your key. Their papers. You review every mark. You keep the pen.
The test is already written. The key is already in the folder, with the partial credit you give and the phrasings you accept. The papers are a pile on the desk. The work is applying that key to every page, in the same way, from the first paper to the last.
The Graider AI red pen follows the order you already know. Upload the test and the answer key. Photograph the stack, with even light and the full sheet in the frame, so the writing is readable. Graider marks each paper against the lines you wrote: accepted answers, partial-credit notes, and the rows of your rubric. You read those marks before a student sees them.
Every classroom has its own marking language. Some items want the exact term from the lesson. Others accept an equivalent if the reasoning is clear. Units, significant figures, and working that must be visible are your calls. Partial credit is a second line on the key: the partial response, and the points it earns.
When those lines live on the key, paper 12 and paper 30 meet the same standard. A phrasing you listed as full credit is full credit on both. A method mark you listed as 1 of 2 is 1 of 2 on both. A response with no matching line is one you read yourself. The score still waits on your review. Grade against your own rubric walks through why that document stays the source of truth.
A general chatbot, asked only for a grade, fills in what a strong response looks like from general knowledge of the subject. Your key may be narrower. An item might award the method point when the last line is wrong. The AI red pen applies the key and rubric you uploaded, so the mark a student can ask about is a row you can point to. If you accept a new phrasing after you have started, write it on the key, then pass back through the papers you have already opened.
You photograph student papers with your camera, or you use photos you already took. Even light and the full page in the frame keep the handwriting readable. Graider matches pages to students on your roster, and you confirm that match. Selected answers, short facts, method marks, and longer written items are then read against the documents you uploaded. The prompt stays on the test. The scoring stays on the key.
Reading the first pass is part of keeping the pen. Open answers flagged as hard to read, scores between two point values, and any page you want to see yourself. A faint line or work in the margin is yours to judge. Change the score when your judgment and the first pass disagree. The score a student sees is the one you kept.
Keeping the pen means the feedback students receive is feedback you released. Turn a comment on when it should travel with the paper. Leave it off when you will teach that item with the class. Edit a comment so it sounds like the note you would have written in the margin, in the words you already use.
On a short item, name the row and one next step. "Question 3: the key awards 1 of 2 when the cause is named and the source is missing. Add which document supports it." On a longer answer, name the criterion the rubric used and the one change that would move the score. How to give feedback on tests covers tying each comment to your rubric and handing the paper back with that note attached. You override any mark you disagree with, and you keep the pen on that override. Students see the paper when you release it.
After you review, hand each paper back as a PDF or an email. One PDF per student holds the pages they wrote, the score you kept, and the comments you turned on. Name the file with the class, the assignment, and the student. Email that file from your school account, or return it through the path your school already uses. Match the name on the paper to the name on the file. Absent students can receive the same file when they are back.
A grading pile asks you to hold one standard from the first page to the last. Fatigue changes how a phrasing feels halfway through. The paper you just marked becomes the feel of the next one, and a sentence you accepted early can lose the point near the end when that decision lives only in memory.
Writing the standard on the key, then applying it to every photograph, keeps the first paper and the last paper on the same row. You still read the borderline cases, change a mark, and choose the comment.
The AI red pen is for teachers who already have a test, an answer key, and a sense of how they mark. Photograph the papers, review and toggle feedback, keep the pen, and hand the work back as a PDF or an email.

You do. Turn a comment on when it should travel with the paper. Leave it off when the class will correct that item together. Edit any note so it sounds like the margin comment you would have written. The score a student sees is the one you kept.
Marks come from the test and the answer key or rubric you uploaded. Accepted answers, partial-credit notes, units, and method marks stay on that document. You review hard-to-read pages and any score you would want to explain, and you override a mark when your judgment disagrees.
After you release the work, each student gets a PDF or an email. The file holds the pages they wrote, the score you kept, and the comments you turned on.
