An AI grader for language teachers marks the paper quiz you already give: vocabulary items, translation lines, and a short response in Spanish, French, or another language you teach. You already know which spellings, translations, and short responses earn the points.
Graider is the AI red pen for paper grading, a product of DM Liquidity LLC. You upload the test and the answer key or rubric, photograph the student papers, and Graider marks each question against that key. Each question gets one score and one comment. You review and override any mark, toggle feedback, keep the pen, and hand the work back as a PDF or an email. The public site is graider.org. AI grading for teachers follows the same path in AI test grading.
Your key. Their handwriting. You keep the pen.
A Spanish quiz holds the examples. Question 3 is the word for library. Question 6 is one English sentence to translate. Question 10 is four sentences about family, using words from the unit list.
An AI grader follows the answer key you upload. Write every variant you accept, with the points it earns, before you photograph the stack.
For question 3, biblioteca can be 2 points. If the item also accepts the English gloss library, give that line its own points. Question 6, "The dog is in the house," can take "El perro está en la casa" for full credit. Add each other full-credit sentence, and add each partial sentence on its own line with the points and a short example.
Put a short response on the rubric you upload with the key, and keep the prompt on the test. How a fixed key and a rubric divide a paper is in answer key grading vs rubric.
Accent and spelling decisions belong on the key, as the strings you accept. Graider reads the handwriting into text and marks that text against those lines. The read can miss or add an accent mark, so check accented answers against the paper at review. You choose which forms earn points.
If café and cafe both earn full credit, list both. If only café earns full credit, list cafe at the partial points you already give, or leave it off the key and score that paper yourself. Français and francais, año and ano, and tú and tu follow the same pattern. Está and esta are different words in Spanish. Put a form on the line only when you award it points.
Synonyms follow the same list. If the item for house accepts hogar as well as casa, write hogar with its points. If hogar misses that item, leave it off the key.
Acceptable translations are sentences you list. "El perro está en la casa" and "El perro está dentro de la casa" can both be full credit when you teach both. When the item runs into English, write each English version you accept. A translation that keeps the meaning and misses a small word can earn partial points when you put that example on the key.
Partial credit is a line on the key or a level on the rubric, with the points and a short example.
On vocabulary, a missing accent can be 1 of 2. Write that spelling and the 1. "la problema" can be 1 when that is your rule, and "el problema" 2. On translation, word order off might be 2 of 4, and the right idea with the wrong tense might be 2 of 4. A missing word that changes the meaning might be 0. Put each example on the key.
A comment such as "meaning is here, and the tense still needs work" can sit on that line. Graider returns one score and one comment for the question. The partial points live inside that one score. Read a response with no matching line yourself and set the points on that paper. Add the wording to your key for the next quiz.
Question 10 is four sentences about family, with at least three words from the unit list. Score it against the rubric you upload. Full credit, 6 points, can require four complete sentences, three unit words used in a way that fits, and meaning a classmate could follow. A middle score, 3 points, can be clear meaning with fewer unit words, or sentences that stop short.
Graider marks that question against the rubric and returns one score and one comment. A longer response gets one score and one comment as well. You review that score and edit that comment. A useful comment names what met the rubric and one next step: "You used casa and hermano clearly. Add one more unit word and finish the fourth sentence." Shorter items are covered in short answer grading with AI.
Graider does not read or score diagrams, graphs, or drawings. If the response also asks for a sketch, set those points yourself and keep them inside the one score. A written label can stay on the key, inside the one score and one comment for that question.
After the stack is marked, you review. Each question has one score and one comment. Keep the points when the text matches your key and you agree. Change the score when you disagree, and edit the comment into the sentence you would write in pen.
Check every Low confidence badge. That badge is the only flag. It means the read confidence on a hard-to-read answer is low. Read the student's answer as text, compare it with the paper and the key, and override when you disagree.
Graider reads handwriting into text. An answer it cannot match to a question is dropped. When a vocabulary blank comes back empty, look at the paper and set the points if the response is on the sheet. You can override any mark. You keep the pen.
Toggle feedback before a comment goes home. Turn it on when the note should travel with the score, and off when you will say the note with the class. A missing-accent comment on question 3 can go home. A comment on question 10 that you plan to teach with the class can stay off.
Hand the work back as a PDF or an email. When you include the score, it shows points earned out of points possible, with the prompt and the student's answer as text. When you include feedback, the comment you kept sits with that question. Student papers and account data aren't used to train models or for advertising.
An AI grader for language teachers marks paper vocabulary, translation, and short responses against the answer key and rubric you upload. Graider returns one score and one comment per question. You review and override any mark, toggle feedback, and hand the work back as a PDF or an email.
Write each accepted spelling, synonym, and translation on its own line, with the points it earns. If café and cafe both count, list both. If only the accented form earns full credit, list partial points for the other form, or leave it off the key and score it at review.
Against your rubric, as one score and one comment for that question. The rubric names what full credit includes, what a middle score includes, and the points. You review that score, edit the comment, and override when you disagree.
It is the only flag, and it means the read confidence on a hard-to-read answer is low. Read the answer as text, check it against the paper and your key, and override when you disagree. An answer the reader cannot match to a question is dropped, so set the points yourself when the writing is on the sheet.
