About Consent O Matic
Consent-O-Matic is a browser extension developed by the Centre for Advanced Visualization and Interaction (CAVI) at Aarhus University. It handles cookie consent banners that ask to process data on websites, which can otherwise require repetitive clicks.
After you set your preferences during installation, the extension searches pages you visit for consent pop-ups it knows how to handle. When it recognizes a banner from a supported Consent Management Platform, it applies your choices automatically and shows a checkmark next to the extension icon. It currently works with more than 200 CMPs, including UserCentrics, CookieBot, and OneTrust, as well as banners for specific websites.
It suits people who see the same banners repeatedly, especially if their browser clears cookies on close. Preferences are stored in the browser, and the extension can be turned on or off for individual pages.
