Why students keep it open
Less tab switching, less repetitive work, and answers right on the coursework page.
Canvas already has enough friction. Keeping the workflow on the page was the main reason I kept using it.
Maya Chen
Canvas · Pre-med
The Moodle matching questions used to eat so much time. This made those way less annoying.
Jade Carter
Moodle · Business
Brightspace already has too many clicks. Not having to copy every question somewhere else honestly made the workflow feel normal again.
Sofia Brooks
Brightspace · Nursing
The double-click flow is why I kept it. On timed Canvas work, it made the whole process feel less chaotic and much easier to get through.

What sold me was the graph and numeric stuff. Most tools are fine until the questions stop being easy.
Liam Ortiz

Using my own notes is what made it actually useful. For class-specific questions, that part helped way more than generic answer tools.

The important parts: supported platforms, question formats, docs, chat, pricing, and how the workflow actually works.
What is QuizHack?+
QuizHack is a Chrome extension for homework help on learning platforms. It is built to keep the answer flow close to the question, reduce tab switching, and support harder coursework formats without forcing you into a separate copy-paste workflow.
How does QuizHack work on the page?+
You open QuizHack from the coursework page, pick the mode that fits your situation, and work question by question. Depending on the mode, QuizHack can show a panel, a small status indicator, or no visible on-page UI at all.
What are Undetectable, Pulse, and Mentor modes?+
Undetectable keeps the workflow off the page visually, Pulse shows only a small status indicator near the cursor, and Mentor opens the side panel with worked answers and related guidance. The modes change how visible the workflow is, not whether the product works.
Does QuizHack include AI chat?+
Yes. QuizHack includes built-in AI chat so you can ask follow-up questions, clarify concepts, and work through related material without leaving the overall workflow.
Do I need to upload documents to use QuizHack?+
No. Documents are optional. You can use QuizHack on its own, then add notes or study files only when the question depends on class-specific material or you want more context.
Does QuizHack have monthly and yearly pricing?+
Yes. QuizHack offers monthly and yearly pricing. The yearly option is the lower-cost plan, with a 50% discount compared with paying monthly over time.
Which platforms does QuizHack support?+
QuizHack is built for platforms such as Canvas, Moodle, D2L Brightspace, Blackboard Ultra, edX, and Google Classroom and more. The goal is to work from the coursework page itself instead of pushing you into a different workflow.
Can QuizHack handle more than basic multiple choice?+
Yes. QuizHack is built for multiple choice, multi-select, numeric input, matching-style prompts, and other denser coursework layouts that show up across real assignments.
Can QuizHack use study notes or uploaded documents?+
Yes. You can upload study notes, summaries, and other documents when the answer depends on class-specific material. That is especially useful for harder prompts where generic context is not enough.
How fast does QuizHack return answers?+
QuizHack is designed around a fast answer loop. The product is built to open quickly, stay close to the question, and return answers in seconds instead of making you repeat the same longer tab-switching process for every item.
What do the plans include?+
Both monthly and yearly plans include the full QuizHack product. That includes the extension workflow, supported question formats, study-note and document context, built-in AI chat, and unlimited question flow.
Can I cancel or request a refund?+
You can cancel so the subscription does not renew for the next billing cycle. QuizHack may also offer refunds in appropriate cases, including where required by law, duplicate charges, or cases we approve after review. Full details are on the Terms of Service page.
