In-depth safety analysis

This extension requests powerful permissions, including access to all URLs and the ability to read website content, capture pages, and modify data on any site. It can also read cookies and run scripts, which is typical for a tool that captures and annotates web pages. While these permissions match its core function, they grant extensive access to everything you do in the browser.

For any extension that can interact with all page content, a careful user should consider the sensitivity of sites they visit while the extension is active. Even with honest current code, a future compromise or a malicious update could leak private data. As with any tool that has full page access, it is wise to verify the publisher’s reputation and keep an eye on update frequency.

In ExtensionTrust’s assessment, the strongest dimension is Community Reputation (93%), reflecting positive user feedback. The weakest is Maintenance & Ownership (30%), which may indicate slower updates or less transparent ownership. The Data & Privacy score (93%) is based on developer declarations, so it's reassuring but self-reported.

AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.
