Read. Draft. Fill.
Then make it yours.
One compact companion brings reading, drafting, and filling together—without taking the final decision out of your hands.

Fewer clicks. Still your call.
Apply answers to supported fields, then check the results. You decide when to move on or submit.
*iLearn/eLearn support depends on your school’s platform and question layout. Moodle and Brightspace adapters are available in extension 1.15.0 and later; real-school compatibility is still being tested. Built for standard choice and plain text/numeric fields. Complex question formats need manual entry. Always review AI-generated answers.

Questions before you get started?
We’re a ticket away.
What am I paying for?
Your Casper license connects the desktop app and Chrome companion on one computer. It covers Casper’s reading and filling workflow, not a ChatGPT subscription. You sign in with your own ChatGPT account.
What do I need to get started?
A Mac running macOS 12 or later, or a Windows 10/11 PC with an Intel or AMD 64-bit processor, Google Chrome, a Casper license, and your own signed-in ChatGPT account. Keep the Casper desktop app open while using the extension.
Which forms and quiz fields work?
Google Forms, Canvas Classic, and Canvas New Quizzes support standard choice and plain text/numeric fields on supported layouts. Grids, matching, images, ordering, uploads, and rich-text questions need manual entry. The latest extension also includes Moodle and Brightspace adapters for recognized layouts, including some sites called iLearn or eLearn. These newer adapters have been tested on practice pages, not real school sites. Support depends on your school’s platform and question type.
Will Casper submit anything for me?
No. Casper fills supported fields for you to review. Next and Submit stay manual. Draft answers can be incorrect, so check them before continuing.
Do I need an API key?
No API key is required. Sign in with your own ChatGPT account. Its availability and usage limits apply; Casper doesn’t provide unlimited AI usage or a separate ChatGPT subscription.
How does billing work?
Weekly is $2.99 USD, monthly is $9.99 USD, and yearly is $59.99 USD. Each plan renews at its weekly, monthly, or yearly interval until cancelled. Each license covers one computer. Checkout uses PayPal recurring billing; manage or cancel your subscription in PayPal. Your key appears on a private receipt page after payment confirmation. Save that receipt link or download your key.
How do I get support?
Join the Casper Discord and open a private support ticket. Include your operating system and Casper version. Never share passwords, product keys, or payment information in a public channel.
