What permissions does the extension need?
Only activeTab — which lets the extension read the current tab's URL when you click the popup icon. It never runs in the background, and never reads page content.
Does it work on every website?
Yes. The extension opens the AI Website Detector analysis page for any domain. It cannot run on browser internal pages (chrome://, about:) because those are restricted by browsers.
Is it free?
Completely free. No account, no subscription, no data selling.
What browsers are supported?
Chrome, Edge (and any Chromium-based browser) via the Chrome Web Store. Firefox via Firefox Add-ons. Safari is not currently supported.
Does the extension send my browsing history anywhere?
No. The extension only reads the current tab URL when you click the popup icon. No browsing history is collected or transmitted.
