## Overview

CoGrader turns the slowest part of teaching into a few minutes of review. You import an assignment from Google Classroom, Canvas, Schoology, Brightspace, Blackboard, or a plain upload of PDF, DOCX, or photos of handwriting. Then you attach a rubric — one from the built-in library of 500+ standards-aligned rubrics, or your own — and CoGrader scores every submission against that rubric, writing a comment for each criterion that tells the student what worked and what to fix next.

What separates CoGrader from generic chatbots is the evidence layer. The team publishes a validation study against official Texas STAAR raters where scores landed within one point of a human rater in 98.3% of cases and matched exactly 80.4% of the time, alongside an IES research award from the U.S. Department of Education and field studies in real districts. Teachers still approve every score and comment before students see it, so the AI drafts and the educator decides.

Beyond the core grader there is handwriting support that sorts scanned pages by student, an originality checker for plagiarism and AI-written text, a rubric generator aligned to state standards, class dashboards showing which criteria the whole class struggled with, and free tools students can use on their own essays. It is used by a reported 100,000+ teachers across 16,000+ US schools.

## Pricing & Plans

Freemium. The Starter plan is free forever for teachers and covers 150 student submissions per month, rubric building and sharing, FERPA compliance, and LMS integration. The Individual plan is $19/month, or $15/month billed annually, and raises the cap to 350 submissions with grammar checking, plagiarism and AI detection, and a class performance dashboard. Schools & Districts and Higher Ed & Enterprise plans are quoted based on size and add unlimited submissions, bulk user management, institution-wide analytics, API access, and onboarding. Educators can also earn the Individual plan free through the Advocate program.

## Key Features & Capabilities

- **Rubric-based AI grading:** Score essays and open-ended responses against your own rubric or one of 500+ standards-aligned rubrics, with a written comment for every criterion.
- **Handwritten assignment support:** Photograph paper essays from your phone or the copier, and CoGrader reads the handwriting, groups pages by student, and grades the whole set.
- **Two-way LMS sync:** Import submissions from Google Classroom, Canvas, Schoology, Brightspace, Blackboard, DMAC, and more, then push grades and feedback straight back.
- **Originality and AI detection:** Flag possible AI-assisted writing and check submissions for plagiarism before you return feedback.
- **Class analytics dashboard:** See average scores by criterion and surface which skills the class as a whole needs reteaching on.

## Primary Use Cases

- **Grade 150 AP Lang essays in one sitting (High school ELA teacher):** Import a class set, attach the AP Lang rubric, and review AI-drafted scores and Glow/Grow comments instead of writing 150 of them from scratch.
- **Digitise a stack of paper essays (Middle school teacher):** Snap photos of handwritten essays, let CoGrader sort pages by student and read the handwriting, then export a gradebook CSV.
- **Standardise feedback across a department (Curriculum coordinator):** Share a rubric library so every teacher in the department grades to the same criteria and students get consistent language.
- **Track writing outcomes at scale (School or district leader):** Use institution-wide reporting to see growth areas across classrooms and target professional development where it matters.

## Strengths

- Validation against official state raters is published with numbers, not just claims
- Teachers approve every score and comment before students see anything
- Generous free tier and full LMS integrations make it easy to pilot
- Handwriting support is rare and genuinely useful for paper-based classrooms
- Class-level analytics turn grading data into reteaching decisions

## Limitations

- Free tier caps out at 150 submissions per month, which heavy graders will exceed
- Plagiarism and AI detection sit on the paid Individual plan
- Some features are strongest for US standards, so non-US teachers get less from the rubric library
