CoGrader vs EssayGrader
EssayGrader and CoGrader are both AI grading tools built for Teachers.
EssayGrader is the most accurate AI grader on the market
In independent evaluations, Essay Grader AI consistently outperforms other platforms. Our AI models are refined to grade accurately using thousands of real rubrics aligned with state, national, and international standards - so the feedback actually mirrors how teachers grade.
Seamless LMS integrations - no middleware needed
Unlike CoGrader, EssayGrader connects directly with Google Classroom, Canvas, and Schoology. No third-party tools required. That means less app friction, quicker setup for teachers and stronger data privacy for students.
No district license required - teachers are in control
Unlike CoGrader, EssayGrader doesn’t lock core features behind a school or district contract. Just create an account, connect the LMS of your choice and start grading. No delays. No admin barriers.
Built to empower teachers, not replace them
EssayGrader is designed with educators in mind. From rubric customization, MLA/APA citation support to assignment-level insights, every feature supports your existing grading workflow - not some imagined version of it.
More than just a grade
EssayGrader delivers comprehensive feedback reports, grammar reports, classroom-ready AI-writing detection, plagiarism checks, and feedback students can actually use to improve - not just to get a grade.
Created by teachers and technologists who get it
This isn’t a generic ed-tech product. EssayGrader was built by people who understand the demands of the classroom because they worked in it for years - and it shows in every detail.
No ads. No Gimmicks. No sales team.
We don’t do marketing. Every dollar is invested back into improving our product. Our teachers are our best salespeople. Every district that uses EssayGrader came to us because their teachers loved the product and shared it. Despite not investing in marketing, we are the most widely adopted AI Essay Grader for K-12 teachers in the US.
We’re proudly independent - not venture capitalist (VC) backed
We’ve turned down multiple VC and private equity offers so we can stay true to our mission: helping teachers. Without investors steering the ship, we have full control over what we build, how we build, and when we build it. We don’t make product or pricing decisions based on investor demands, spreadsheets or quarterly growth targets - we make them based on what teachers actually need. If it doesn’t make your life easier, we don’t build it and if it does, we will move mountains to make it happen. You’re the only ones we need to keep happy.💜💜
What teachers say about our essay grader
%201.svg){kind=icon}
"EssayGrader is unparalleled in giving students the opportunity to practice their writing and receive the feedback they need to improve. The extensive practice my students get from EssayGrader reduces my grading workload and prepares them for the timed writes I read and score, as well as for the AP exam itself."

"This is the first time that an innovation has directly impacted my ability to reach students at a higher level. EssayGrader helps me not to be bogged down by the tedious, albeit necessary, minutia of things like conventions and grammar which frees up my grading time for me to teach and evaluate the “art” of writing."
"EssayGrader 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. I loved it so much that I recommended it to our principal, and we are looking to roll this out with other teachers at our school."
