What our analysis found

Web Highlights: PDF & Web Highlighter + Notes & AI Summary, used by 200,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites, can inject scripts into pages and can observe network requests. It comes from a trusted publisher and was last updated in October 2026.

Analyst notes

The reviewed source files consist solely of UI components (LitElement web components) and PDF handling utilities, all aligned with the extension's stated purpose of highlighting and annotating websites and PDFs. No malicious behavior, data exfiltration, or unauthorized network requests were found in the provided code. The broad permissions are typical for a highlighter tool and are justified by the disclosed functionality. The publisher is reputable (Google trusted badge, featured listing, valid email, positive reviews), and the permhash cluster is clean (0% malware). The ML model likely overfit on permission patterns and common minified web component code patterns.

You can also configure a blacklisted domain list with patterns in the settings under "Excluded" domains. ➡️ Sort highlights manually: Highlights should appear in the same order as on the page. If not, use the drag & drop or arrows in your annotation sidebar to rearrange them as needed. ➡️ Customizable Sidebar: Change the sidebar width by dragging its edge, and align it on the left or right side of the page for a personalized experience. ➡️ Switch to Advanced Highlighter Mode in settings to organize highlights with headings, paragraphs, and more in the sidebar. ➡️ Multiple Colors: Choose from predefined standard and pastel shades or click the plus icon to add your own custom color. ➡️ Note Taking: Use standard keyboard shortcuts like CMD + B for bold, CMD + U for underline, etc., in the note-taking editor for efficient formatting. ➡️ Reader Mode: Click “Open in Reader” to view any article in a clean, distraction-free layout with customizable fonts, colors, and spacing.
