If you’re a teacher looking for the best Chrome extensions, you’ve likely struggled with one or more of the following issues:
- Copying and pasting work, scores, and feedback between docs, gradebooks, and your LMS by hand
- Switching back and forth between a dozen tabs and screens to manage all the different apps you use for grading, planning, and everything else
- Finding a tool that actually integrates with your day-to-day instead of becoming one more thing to log into
The issue is that many tools can’t solve these problems because they aren’t available as Google Chrome extensions. This creates extra steps in your day, like uploading assignments by hand or pasting lesson plans into Docs.
That’s why this guide covers the best Chrome extensions for the everyday tasks teachers struggle with, including grading, feedback, lesson planning, classroom management, and student engagement. Here’s a brief look at all nine and how they compare, starting with our own AI grading tool, CoGrader.

What Types of Chrome Extensions Can Teachers Use in the Classroom?
Chrome extensions for teachers typically fall into specific categories depending on the task they help you handle, including:
- Grading and feedback: These tools tend to save the most time since evaluating student work and providing meaningful feedback can take up most teachers’ evenings and weekends. These extensions grade writing against your rubric, draft personalized comments, or let you leave quick voice feedback instead of typing it all out.
- Lesson planning and teaching materials: Building what you teach with, from lesson plans and leveled readings to slides, quizzes, and interactive activities. Tools in this group can turn a topic, webpage, or rough idea into classroom-ready material in a fraction of the time it would take to make it from scratch.
- Classroom management and productivity: Everything that quietly slows down your day, like switching between dozens of tabs or trying to record video lessons that would resonate better with students. These extensions help keep your workflow and your attention under control.
- Accessibility and student support: Making grade-level content accessible for every student, including those with IEPs, dyslexia, or English-language needs. Tools in this group add text-to-speech, dictionaries, word prediction, and reading support directly to the pages and documents students already use.
Not every teacher will need multiple tools or one for each use case. It entirely depends on how they spend their days and what tasks take up the most time in their classroom.
Many teachers see the biggest returns when they implement a tool for grading and feedback. With that in mind, we’ll introduce CoGrader, our very own AI essay grading tool, below.
CoGrader: AI Essay Grading for Teachers
CoGrader is an AI essay grader that gives teachers their time back without sacrificing the quality of feedback. It connects to the platforms you already use, grades student writing against your own rubric, and drafts personalized feedback for every student in a fraction of the time it takes.
If you’re using Canvas or Schoology, you can get direct access via a Chrome extension that grades right inside the gradebook. Google Classroom connects directly, so submissions pull in automatically.
The result is the same whether you teach in Canvas, Schoology, Google Classroom, or another LMS. You’ll spend less time on grading tasks and more time teaching and engaging with students.
Below, we’ll show you how to download the CoGrader Chrome extensions and explain the platform’s key features.
How to Use the CoGrader Chrome Extensions
Getting started takes a couple of minutes, and the exact setup depends on where you grade assignments and manage your classroom.
CoGrader supports Google Classroom, Canvas, Schoology, DMAC, Microsoft, Brightspace, and Blackboard. We offer dedicated Chrome extensions for Canvas and Schoology, so grading happens right inside the gradebook, and every other LMS connects directly within the CoGrader platform in your browser.
Either way, your classes, assignments, and submissions import in just a few steps.
Canvas
The Canvas extension can be added from the Chrome Web Store. After adding it and connecting your account, a CoGrader button will appear in Canvas.
Open any assignment, import submissions with one click, then grade and send feedback back to students without ever leaving the gradebook.
Note: Canvas integration is available on Schools & Districts plans.
Schoology
The Schoology extension installs the same way from the Chrome Web Store.
Once it’s connected, you can pull an assignment’s submissions into CoGrader directly from Schoology, grade against your rubric, and return scores and comments to students in place.
Note: Schoology integration is available on Schools & Districts plans.
Google Classroom
No extension is needed to integrate CoGrader with Google Classroom.
All you need to do is sign in to your account, click “Grade class +,” select the assignment type (essays or quizzes), and select Google Classroom.
Note: Google Classroom integration is available on the Standard plan and above.
Other LMS platforms (DMAC, Microsoft, Brightspace, Blackboard)
Similar to Google Classroom, DMAC, Microsoft, Brightspace, and Blackboard connect directly inside the CoGrader platform in your browser.
Link your account once, import your assignments, and grade them in the same place. No manual file downloads or uploads are required.
Grade Against Your Own Criteria with Customizable Rubrics
Many AI essay-grading tools will score writing against their own vague sense of what good writing is. This could work for some teachers who assign basic writing tasks, but if you want to give better overall feedback and more accurate grades, you’ll need a tool that lets you add a rubric.
With CoGrader, you can choose a rubric that fits your classroom. Teachers have full access to a rubric library with:
- Standards for all 50 U.S. states
- Curriculum and test frameworks like AP, IB, Smarter Balanced, Cambridge, and MSAA
- International standards, including Australia, England, New Zealand, and the UK
- Every major subject, from English and Social Studies to Math, Science, Arts, and World Languages
- All grade levels, from elementary through higher ed
There are a few ways to set up a rubric in CoGrader:
- Upload a rubric you already use as a document, file, or image
- Select a ready-made one from CoGrader’s library (the standards, subjects, and levels above)
- Generate a brand new rubric with CoGrader’s AI Rubric Generator
CoGrader’s Rubric Generator is highly intuitive. You can either choose a few criteria, including essay type, grade level, and an optional standard, and let it build the rubric from there. Or you can skip the menus and just describe what you want in plain language, like “Create a rubric for a 10th-grade compare-and-contrast essay on two poems, weighting theme, literary devices, and organization.”
Either way, CoGrader reads what you’ve given it and produces a working rubric matched to the assignment in seconds. It’s also flexible for teachers throughout the entire process. If you change the rubric after you have already begun grading, CoGrader regrades the entire class automatically, without entering anything manually again.
Grade a Full Class Set of Assignments in Minutes
Grading is usually the most time-consuming task for teachers, especially when it comes to grading writing assignments. It usually takes between 15 and 30 minutes to grade a single essay, so if you’re grading a class size of 100 students, it can take anywhere between 25 and 50 hours to finish grading one assignment.
This is exactly why we built CoGrader. Our tool integrates with your LMS and works directly in your web browser, so you can grade entire class sets 80% faster.
The grading process happens in four steps:
- Import assignments. Open an assignment and pull every student submission into CoGrader, with no downloading, uploading, or sorting through folders.
- Choose your rubric. Choose a saved rubric, pick one from the library, or generate one on the spot, then set the grade level so scoring is calibrated to what you’re actually teaching.
- Grade the entire class. CoGrader evaluates every submission against your rubric simultaneously and drafts feedback tied to specific highlighted passages in each student’s writing.
- Review and send back. Submissions land in a review queue for your sign-off, then approved grades and comments return to students through Canvas or Schoology instantly.
CoGrader also allows teachers to customize various aspects of grading. You can adjust the settings to change the feedback style (like Glow and Grow, Two Stars and a Wish, or WWW/EBI) and grading parameters (such as strictness, tone, reading level, and depth) before grading.
One thing CoGrader won’t do is bulk approve student assignments. Every essay needs an individual sign-off before it reaches a student, which keeps teacher judgment in the process, no matter how fast the grading goes.
Know What to Teach Next with Class-Wide Analytics and Insights
After a long grading session, teachers usually make lesson-planning decisions based on overall grades or on a gut feeling from a few assignments that stood out.
For example, say you grade a set of argumentative essays and notice that five students never backed up their thesis with real evidence. Those papers tend to be most memorable, so you walk away assuming the whole class struggles with evidence and plan to reteach the concept in class.
In reality, it was only those five students, and the other twenty-five were ready to move on, now stuck sitting through a lesson they didn’t need.
CoGrader automatically tracks this and displays the key analytics and insights in a dashboard for teachers.
Once grading is complete, you get several views into how your class actually performed:
- Student view: Open up any single student and see how they performed on each rubric criterion, so support goes to the right students on the right skills rather than a vague sense of who’s behind.
- Criteria charts: A view that plots the whole class against every criterion at once, making it obvious at a glance which skill held up and which one fell apart.
- Score distributions: See how many students landed below, at, or above expectations, instead of hiding behind a class average.
You can also generate future lessons using the class-wide analytics. This allows teachers to automatically generate a ready-made teaching plan based on class strengths and areas for growth.
