Moodle Quiz Helper Extensions: What They Do and What They Don't
AI quiz helper extensions for Moodle explained honestly. How they read questions, which modes exist, their limits and how to use them for studying.
Quiz helper extensions are one of the fastest-growing categories of study tools. Some marketing around them is wildly exaggerated. This article explains, plainly, what these tools do on Moodle, where they fall short and how to use one responsibly.
How a quiz helper works
A quiz helper is a browser extension. When you trigger it, it:
- Reads the question from the page (selected text, page text or a screenshot).
- Sends it to an AI model.
- Shows the answer on the page.
TrustStudy, for example, shows a compact note like 2 : a in the corner of the page. Alt + X gets the answer, Alt + C shows or hides it.
Input modes, and why they matter
How the extension reads the question changes the quality of the answer:
- Selected text: you highlight exactly the question. Most precise.
- Page text: the whole visible text is sent. Fast, but noisy on pages with many questions.
- Screenshot: the AI sees images, diagrams and formulas. Needed for visual questions.
- Double-click: in TrustStudy, double-clicking a question sends just that block. On standard radio-button or checkbox questions, it can also select the choice the AI picked; otherwise it shows the answer.
What these tools do well
- Common subjects with clear, factual answers.
- Multiple-choice and true/false questions.
- Explaining concepts when you ask follow-up questions in a chat.
- Saving time when checking practice quizzes.
What they do not do
- They are not always right. Course-specific questions ("according to the lecture...") can trip up any AI.
- They do not work in locked browsers. Safe Exam Browser and similar tools do not load extensions.
- They cannot see what is not on the page. If the question depends on a file or video, the AI does not have it.
- They are not invisible. Moodle's logs, timing data and proctoring are separate from your browser, and nothing about an extension changes what your teacher can see.
Choosing a quiz helper
Look for clear pricing, a privacy policy, minimal data sent (only when you trigger it) and a choice of models. Read our honest TrustStudy safety review for an example of what to check, and our best Moodle Chrome extensions for alternatives.
Use it the right way
The bottom line
Quiz helper extensions are useful study tools, not magic. Use them to get faster feedback while you practise, and you will need them less and less as your understanding grows. For a step-by-step method, see working through Moodle practice quizzes with AI.

Install extensionFrequently asked questions
What is a Moodle quiz helper extension?
It is a browser extension that reads a question on a Moodle page and asks an AI model for the answer, showing it on the same page. Some can also select the matching choice on standard forms.
Do quiz helper extensions work in Safe Exam Browser?
No. Safe Exam Browser is a separate, locked-down browser that does not load Chrome extensions.
Are quiz helper extensions accurate?
They are as accurate as the AI model behind them, which is usually high for common topics and lower for course-specific details. Always treat the answer as a second opinion.
