What Is an edX Answers Tool?
edX is a major MOOC and professional-learning platform, hosting courses from top universities and companies and now part of 2U. Its courses mix video, reading and auto-graded problem sets, so learners face a steady stream of graded checks — multiple choice, checkboxes, dropdowns, numerical entry and short written answers — that gate progress through each unit.
An edX answers tool like QuizSolve is an AI extension that works directly inside the edX course view. Instead of copy-pasting a problem into a separate tab, you double-tap it: QuizSolve reads the on-page question text and any answer choices, sends them to an AI model, and shows a reasoned answer with an explanation on the page. It's free to start — 5 free questions per day plus 2 screenshot solves, with no account required. Because edX serves year-round MOOC and professional learners, it helps whenever you're studying, not just during a semester.
How QuizSolve Solves edX Questions in 2 Taps
Install the Extension
Add QuizSolve to Chrome from the Chrome Web Store in one click. No signup, no API keys, no configuration — the extension is under 1 MB and installs in seconds.
Open Your edX Course
Go to your edX quiz, problem set or graded unit in a normal Chrome tab. QuizSolve detects the edX course problem view automatically.
Double-Tap for the Answer
Double-tap any question. QuizSolve reads it, runs it through the AI, and shows the answer plus a brief explanation directly on the edX page — no tab switch.
Under the hood, QuizSolve parses the problem container in the edX page's DOM — extracting the prompt, any images, and the available answer choices — then sends that context to a state-of-the-art AI model. The round trip from double-tap to on-screen answer typically takes one to two seconds.
Because everything happens on the edX course page itself, there's no separate window to manage and no copy-pasting. edX problems include auto-graded checks that re-test the concepts behind each unit, so the explanation that comes with each answer is the part worth reading: understanding why an answer is correct is what actually helps you retain the material.
What edX Question Types Does QuizSolve Support?
QuizSolve handles the question formats edX problems and quizzes use most:
Identifies the correct option from the available choices with reasoning
Finds every correct option in 'select all that apply' items
Picks the correct value from an edX dropdown menu and explains why
Computes the exact numeric value the problem expects
Provides the precise term, expression or formula the item requires
Drafts a concise answer to open-ended prompts with reasoning
edX's formatting quirks — randomized answer orders, one-problem-at-a-time display, and images embedded in the stem — are handled automatically. QuizSolve works on whatever the edX course view renders.
Is It Safe? What edX Records
QuizSolve runs entirely on the edX page and doesn't switch tabs, open new windows, or inject a visible widget, so there's no obvious on-screen tell during a screen-share. That said, honesty matters: edX does track basic course and problem activity, and some programs enable additional monitoring. Treat any graded assignment accordingly.
The important boundary: if your course requires a proctoring or lockdown browser — such as Proctorio or a Respondus-style exam environment — the assessment runs in a secured environment where Chrome extensions cannot operate at all. QuizSolve will not run there, and no browser extension can. For a full breakdown of what platforms can and can't detect, see our guide on whether professors can see Chrome extensions.
edX Answers — FAQ
Does QuizSolve work on edX?
Yes. QuizSolve works on the edX course problem view — the standard interface where you complete quizzes, problem sets and graded units in a regular Chrome browser. It activates automatically when it detects an edX problem page, reads the question directly from the page, and returns an answer with an explanation. There's no setup beyond installing the extension: no account, no API key, and no configuration. It does not work inside a lockdown or proctoring browser, because those environments disable all Chrome extensions.
Is QuizSolve free to use on edX?
Yes. QuizSolve has a genuine free tier: you get 5 free questions per day plus 2 screenshot solves at no cost, with no signup and no credit card required. That's enough to get through most day-to-day edX quizzes and problem sets for free. If you regularly hit the daily cap — during an intensive course or a heavy MOOC load — you can upgrade to QuizSolve Pro for unlimited questions and screenshot solves starting at $6.99 per month. There is no paywall before you can try it, which is the main difference from paid-first edX answer services.
Can QuizSolve answer edX numerical and formula problems?
Yes. Many edX courses — especially in math, engineering, computer science and the sciences — use numerical input and text or formula entry rather than plain multiple choice. QuizSolve reads these on-page problems the same way it reads a standard quiz item, computes the value or expression, and returns it with a short explanation. Because these auto-graded checks are designed to verify you can apply a method, reading the explanation (not just the answer) is what helps you handle the next variant of the same problem on your own.
Does QuizSolve solve edX questions with images or diagrams?
Yes. Many edX items — especially in science, engineering and data courses — include diagrams, charts, or figures in the question stem. QuizSolve captures the image along with the question text and analyzes both together using a multimodal AI model. That means it can handle labeled diagrams, graphs, and figure-based questions, not just plain text. Image support works across the standard edX course view, and the answer still comes with an explanation so you understand what the figure was testing.
Will edX know I used an extension?
edX does not have built-in Chrome-extension detection, and QuizSolve works on the page without switching tabs or showing a visible widget, so it doesn't create an obvious tell. However, be realistic: edX logs course and problem activity, and if your program enables a proctoring or lockdown browser, no extension — including QuizSolve — can run inside that secured environment at all. We won't promise you can defeat proctoring, because it isn't true. Use QuizSolve on standard, non-proctored edX problems and treat graded work responsibly.
How is this different from an edX answer key?
Static 'answer key' sites post pre-collected answers to specific courses, which are often outdated, wrong, or for a different run of the course — and edX frequently randomizes questions and values per learner. QuizSolve instead reads your actual question, as it appears on your screen, and generates the answer with AI in real time. That means it works even on randomized or numeric-variant items where a shared answer key would be useless, and every answer comes with an explanation so you can verify the reasoning yourself.
