Most "best AI Chrome extension" lists are padded with tools that have nothing to do with coursework — meeting transcribers, email autocompleters, plagiarism scanners aimed at publishers. This list only covers extensions that actually help with schoolwork in a browser, with what each one costs and where each one falls short.
What makes a study extension worth installing?
Four things separate a genuinely useful study extension from a novelty:
- It works where your coursework already is. If you have to copy a question into another tab, the extension has saved you nothing over opening ChatGPT yourself.
- It reads images, not just text. Diagrams, graphs and answer choices carry most of the information in science and multiple-choice questions.
- It shows working. An answer with no method is useful exactly once. An explanation is reusable on the next question of the same type.
- Its free tier is big enough to judge it. Five questions a week is not enough to know whether a tool handles your subject.

Apex Vision AI
Apex Vision AI is our own extension, so treat the placement accordingly and judge it on the specifics. It reads the question already open on your screen — including diagrams and answer choices — and returns a step-by-step explanation, working inside Canvas, Blackboard, Moodle, Top Hat and most web quiz interfaces. It also ships iOS and Android apps and a set of study tools: study guides, flashcards, practice exams, a math solver and essay drafting.
Free tier: Start with 30 free requests, plus a refill every 12 hours. No card required. Paid: $7.99, $14.99 and $19.99 a month for 500, 1,000 and 2,000 requests. Rating: 4.9 out of 5 from more than 1,900 Chrome Web Store ratings.
Where it falls short: the request cap means it is not the cheapest option for very high volume, and browser coverage is Chrome only on desktop.
QuizSolver AI
The broadest platform coverage in this list. QuizSolver advertises support for more than 20 platforms, including Canvas, Blackboard, Moodle, Google Forms, Microsoft Forms, Quizlet, Kahoot, Coursera and edX, with a screenshot mode and several request types covering solving, explaining and calculating.
Where it falls short: the advertised monthly prices require paying twelve months up front, and the cheapest paid plan is only 120 answers a month. There is no mobile app. See our full QuizSolver AI comparison.
Coursology
A browser extension aimed at quizzes that bundles flashcards, solution verification and automated lecture transcription. The transcription feature is the genuine differentiator here — it is aimed at students who want lecture notes as well as question help.
Where it falls short: narrower subject depth than the general-purpose tools, and pricing is less transparent than its competitors. See our Coursology comparison.
CanvasPass
A single-purpose tool: it works inside Canvas quizzes and nowhere else, at the lowest price in this list ($5/mo for 800 credits).
Where it falls short: Canvas only, no mobile app, and a five-questions-per-week free tier that is too small to evaluate properly. It also markets features designed to defeat exam supervision, which we would not recommend installing — see our CanvasPass comparison for why that matters.
QuestionAI
A scan-and-solve extension: highlight or capture a question anywhere on a page and get an answer back. Simple and fast for one-off questions.
Where it falls short: less structured than the LMS-focused tools, with limited depth on multi-step problems.
Grammarly
Not a homework solver, and that is the point. Grammarly checks grammar, clarity and tone as you write, anywhere in the browser. For essay-heavy courses it is the most broadly useful extension on this list, and its free tier is genuinely usable.
Where it falls short: it improves how your writing reads, not whether your argument is any good. It will not help with maths, science or multiple choice.
ChatGPT
Worth including because it is what most students actually use. Browser extensions put ChatGPT in a sidebar next to whatever you are reading, which removes some of the tab-switching.
Where it falls short: it still cannot see your course context, the diagram, or the answer choices unless you paste them in. That copying is the slow part of the workflow, and it is where information gets lost. Our Claude vs ChatGPT comparison covers the general-assistant options in more detail.
What about extensions that promise to beat proctoring?
Several tools in this category advertise stealth modes, tab-switch blockers and features designed to defeat exam supervision. We do not build them and do not recommend installing them. Using software explicitly designed to circumvent proctoring is treated as academic misconduct at most institutions, and the consequences land on the student, not the vendor. Our position is set out on the academic integrity page.
How should I choose between them?
Start with where your coursework lives. If everything is in Canvas and price is the only factor, the cheapest single-LMS tool wins. If you have courses on several platforms, or you revise from a phone, you need something broader. If your workload is essays rather than problem sets, a writing tool will do more for you than any answer engine.
Then check the free tier is large enough to test the tool on a real assignment before you pay. Any extension that will not let you try it properly is asking you to buy blind.
Are AI homework extensions allowed?
That depends entirely on your institution and often on the individual course. Some courses permit AI assistance with disclosure, some permit it for practice but not assessment, and some prohibit it outright. The tool cannot tell you which applies — check your syllabus and your institution's academic-integrity policy before installing anything. We cover where the line usually sits in is using AI for homework cheating?
Try it on the question you are actually stuck on
Apex Vision AI is a Chrome extension and mobile app that reads the question already open on your screen — including diagrams and answer choices — and explains it step by step, without you copying anything into a separate chatbot. It works inside Canvas, Blackboard, Moodle and Top Hat.
Start with 30 free requests, plus a refill every 12 hours. No card required. AI answers can be wrong — always check them against your course material.
