Frequently asked questions
Are AI Chrome extensions safe to install?+
Safety depends on the extension, publisher, requested permissions, and how you use it. Review permissions and privacy terms, especially before using an extension on confidential pages.
Why use an AI extension instead of a separate chat app?+
Extensions can work closer to the page you are already using, reducing copy-paste for summarization, rewriting, translation, and contextual questions.
Do AI Chrome extensions work on every website?+
No. Browser permissions, restricted pages, site security rules, and product limitations can affect where an extension works.
