What is an AI grader?
An AI grader is a software tool that reads student work and returns a score plus written feedback for each criterion on a rubric. It is not limited to one kind of submission - a good AI grader handles a written assignment, a research paper, a short answer, a photographed page of handwriting or a recorded presentation, and scores each on what that form is actually meant to demonstrate.
The difference between an AI grader and a general chatbot is the rubric. A chatbot gives an opinion about one piece of writing; an AI grader with rubric support scores a whole class against criteria you set, names the criterion behind every point, and hands the result back for you to approve. Nothing reaches a student until you say so, so the final grade stays yours.
What can an AI grader actually grade?
EssayGrader's AI Grader handles various types of submissions in any format - typed, handwritten, spoken and video recorded each judged on the criteria using a rubric that type of submission is meant to demonstrate.

What teachers say

This is a great tool! The grading is almost always spot on and the feedback has been super helpful to the students. The UI is very user-friendly and I was able to create my own rubrics easily. Overall, this tool saves me huge amount of time.
I’ve recently started teaching writing for 5th and 6th grade after all of my teaching experience being in kindergarten. The change is a bit overwhelming! I was looking for tools to help me grade essays to save me time and my sanity. I came across EssayGrader and saw that it left comments and what to fix in essays. I want my students to correct their work so that they are less likely to make those mistakes in the future. I was immediately hooked!! I’m so excited to use this more!!!!!

As an AP English teacher, I have to give many practice eesays to students. Grading essays is very time comsumoing, esp. when I have over 100 AP students. I decided to search online if there was a software or service that can help me with my grading. I first came upon CoGrader. It worked well, but I soon found it to be too complicated and time consuming to enter the parameters. Then, I stumbled on Class Champion, it work well as first, but it also was time comsuming to input parameters and to access the feedback reports. Then, I found EssayGrader, which by now I felt it was going to give me the same experience. However, I soon found that it was easy to input my parameters and access the feedback. It even had a feedback copy feature that help to save me time to provide the feedback to students. In addition, EssayGrader also allows you to make scoring and feedback edits easily. I am very happy with EssayGrader that I am a subscriber and will endorse it to my school district for subscription. I would recommend this service to any teacher or admin who wants to save grading time and have multiple options for feedback.
I absolutely love using Essay Grader! The ease of creating rubrics from a template saves me so much time and makes grading consistent. Assignments are graded incredibly fast with impressive accuracy, and the feedback provided is both thorough and thoughtful. It’s clear and specific enough to really help students grow. This tool has made grading less stressful and far more efficient - I highly recommend it!
EssayGrader's free access got our teachers excited about the potential for AI integration in the classroom, and removed the trepidation around new technology. We were thrilled with the ease and accuracy of the platform and were eager to access the upgraded tools around dashboard analytics, enhanced feedback, and plagiarism/AI generated text flags. The user experience has been low stress even for our less tech savvy staff and the customer service is incredibly responsive. Can't recommend highly enough.
As a principal, I've seen how Essay Grader takes the grading fatigue off teachers' plates while giving students clear and consistent feedback. It ensures essays are graded equally, and from a data perspective, the calibrated scores provide confidence that results are fair and accurate across the board. It also gives us a way to see calibrated, measurable growth over time, which is invaluable for guiding instruction and supporting student progress. I would like to see an admin hub where we could view the whole school's data.
Quick review, but I've been working with this program for a few years and I've seen incredible improvement in the program's usefulness. Additionally, the customer service is exceptional! Essay Grader has really helped me with "grading fatigue" and providing timely feedback. The student facing comments don't feel "canned" and I've seen real improvement in student writing: when students take the time to read the feedback. IMO: The revision aspect of writing is vital, but the reality of providing immediate feedback for revision deems it nearly impossible for most teachers. This program supports writing improvement!
I appreciate the depth of feedback provided on each essay. Not only are mistakes flagged, but so are things that are done particularly well. Suggestions for improvement are spot-on. I also like the fact that I can send feedback reports to the students with or without the score. This allows me some wiggle-room in grades, as I deem acceptable. Overall, this has been a terrific timesaver. I still read my students’ work and know where and how they are progressing, but the feedback they receive is more than what is humanly possible.
I was hesitant to try something new, but it was so easy to get up and running and I appreciate the feedback it provides. I really like the side-by-side panel view, where you can see student work and feedback sections side by side.
EssayGrader can transform the way teachers evaluate student essays. The AI-powered feedback is thorough and insightful, helping to provide more detailed comments while reducing grading time. It provides the teacher with an intelligent analysis that will help them give students the specific guidance they need to improve. It's like having a trusted teaching assistant available 24/7!

I tested it using four different versions of my own CCSS-based info/expo rubric with essays I previously marked on my own ... it is EERILY ACCURATE. The scores were almost exactly what I had given, and the written feedback is concrete and specific. I'm stunned. Get your life back!

This is our first year using Essay Grader, and we have been SO happy with every aspect of this program. Many of our teachers were very skeptical about using AI to grade essays. Now that we are all using it, they absolutely LOVE it! The true beauty of this product is the immediate feedback you can give your students when they complete an essay.

I love using this. It helps me with grading by pointing out positives and negatives in an essay, especially when I am encumbered with essays!
EssayGrader AI has been phenomenal to use for my ELA classes. I grade all of my ELA essays with Common Core State Standards, and it probably saves me 5-6 hours of time per week.
EssayGrader.AI has transformed my classroom. My students can write essays, receive feedback overnight, and revise their work based on detailed and helpful suggestions. The feedback is strictly aligned with the AP rubric (manually uploaded), breaking down scores by each category and offering specific advice on how to improve.

Save yourself hours of grading with detailed ideas for improvement and positive feedback. The communication with support is amazing too.
This is a great time saver for teachers who need to mark a large amount of essays. I am using it to mark the IB internal assessment for my classes.

The site is incredibly user-friendly, and the detailed feedback it provides is amazing. With all the new updates, it’s even more efficient and accurate. It has saved me HOURS of grading and stress!
I’ve used EssayGrader in my previous classes, and it has been an incredibly helpful tool for streamlining the grading process. It provides clear, structured feedback, making it easier for students to understand their strengths and areas for improvement. The automated grading features have saved me so much time while still allowing me to give personalized comments.

I really appreciate how the company provides immediate feedback and support—even on a Sunday! It’s clear that you value your customers and are committed to improving the product by listening to those of us using it daily.
Essay Grader was exactly what I was looking for. I way to give fast feedback to students as emerging writers. This does not replace the teacher, but is a helper in the educational experience. I love the integration with google classroom and the ability to customize the feedback directly into the students document.
Caring CEO who solved my problem completely and immediately. Loved sending my essays here. They did an excellent job. Thank you so much!
EssayGrader is always responsive and innovative. They keep the teacher in mind, and the product saves me a ton of time on a daily basis. The Canvas integration is a wonderful way for me to get feedback to my students quickly and effectively. I also appreciate all the feedback options so I can tailor it to my students’ needs.
My experiences with Essay Grader have been great because of the program's quickness and thoroughness. It's also great because the platform saves me so much time.
The only word I can say about EssayGrader is "excellent!" Its AI grading capabilities are excellent. Once the rubric is dialed in, EssayGrader will score essays very close to what I would score them. Usually with in only a few point difference. It also does a great job at detecting errors and offering suggestions oh how students can improve their right and all this based on the rubric I can create. This offers great flexibility for me as a teacher whether it is short answers, one day quick write essays, or major research papers. And the Google Classroom integration is excellent, seamless, and intuitive. This, along with its excellent grading capabilities saves me hours upon hours of time.
ELA teachers, please get this program!! I love grading my classes using this program and the feedback is generally spot on. Their AI detection tool is top notch and I fully trust it! Worth the $19.99/month. I would actually pay more for giving me so much time back!
A very good grader that really helped me a lot. Not only on the grammar aspects but also my mindset of thinking the content of essays. I would like to recommend it to anyone around me.
AI grader questions
What is the best AI grader for teachers in 2026?
EssayGrader is trusted by 200,000 teachers at 10,000+ schools across all 50 U.S. states, and is rated 4.5 out of 5 on Trustpilot with roughly eight times as many verified teacher reviews as the next largest AI grader. As of September 2026 it is also the only AI grader that publishes its full accuracy studies openly, in the AI Grading Accuracy Center.
What separates an AI grader from a generic AI chatbot is rubric-based grading: EssayGrader scores every submission against your own criteria or any of the 800+ standards-aligned rubrics, names the criterion behind each point rather than returning one overall score, and aligns with experienced teacher scores 96% of the time across a benchmark of more than 22,000 essays.
Judge any AI grader on four questions:
1. Does it grade against your rubric, or its own idea of good writing?
2. Is its accuracy published, with the methodology and sample size shown?
3. Does it show its reasoning, criterion by criterion?
4. Does the final grade stay with the teacher?
EssayGrader answers yes to all four making it one the most sought after AI graders by teachers in 2026.
What kind of student work can an AI grader grade?
A good AI Grader will handle grading submissions in any format - typed, handwritten, spoken, and video recorded. EssayGrader can grade long form research papers, lab reports, short answer responses, class assignments and handwritten work, as well as essays. Each submission type is scored on the criteria that type is meant to demonstrate - a lab report on method and results, a short answer on whether each required part is present, a research paper on sourcing and citation.
Is there a free AI grader with no sign-up?
Yes! the AI grader app on this page can be used without an account, a credit card or even the need for an email address. Simply upload the student submitted work and it returns a rubric-based score. Teachers who create an account get 100 free gradings to start with, then 50 a month, and can import classes, assignments and student submissions from Google Classroom, Canvas and Schoology.
Can an AI Grader read handwriting?
Yes. EssayGrader reads cursive, print and the messy kind from a photo taken on a phone, tablet or the school printer, then grades the transcription like any other submission. The transcription sits beside the original scan so you can check it line by line before the score is sent to the student - which matters, because handwriting reduces accuracy for any AI grader, not just ours. A word extracted wrong could cost a student a point for the wrong reason, so your review step matters here more than for other submission types.
Does an AI grader work without a rubric?
It works, but the score is weaker. Without a rubric EssayGrader applies a general writing rubric matched to the submission type and grade band. Uploading your own rubric, or picking one of the 800+ standards-aligned rubrics, is what makes a score accurate.
Can it grade video essay or an oral exam?
Yes, when you sign up for a free account. EssayGrader transcribes a video or audio submission first, then scores the transcript against the same rubric you use for written work - so a recorded presentation or an oral exam is graded on the same criteria as an essay. The grader on this page handles text grading only; video and audio grading happens inside the app.
How accurate is an AI Grader?
EssayGrader aligns with experienced teacher scores 96% of the time, benchmarked on more than 22,000 essays, with under 4% variance from human grading. Accuracy depends heavily on the rubric - a specific, criterion-based rubric produces a far more defensible score than a general one - and every score names the criterion that produced it so you can check the reasoning. See more about how we consistently maintain our accuracy standards at our AI grading accuracy center.
Can an AI Grader grade a whole class at once?
Yes. A free account lets you upload a folder with student work or import a class straight from Google Classroom, Canvas or Schoology, and EssayGrader grades the full set in one pass - 30 submissions or 300.
Do students see the AI grader's feedback automatically?
No. Every score and comment goes to the teacher first, and nothing is released to a student until you approve it. You can change any score, rewrite any comment, or discard the whole report. AI writing and plagiarism reports are never sent to students at all - those are for your judgment only.
Is it acceptable for teachers to use an AI Grader?
Yes, in most districts, provided a teacher reviews every score before a student sees it - which is how EssayGrader is built. Two things make it defensible if you are asked: every score traces back to a rubric criterion, so you can show how a grade was reached, and student work is never used to train AI models.
On the data security side, EssayGrader is FERPA, COPPA and CCPA compliant, meets WCAG 2.2 accessibility standards, and has a completed HECVAT 4.1.5 on file. Check your own district's AI policy before rolling it out across a department.
