Text highlighting tool for web pages - applies a colored background to user-selected text directly in the DOM

Allows users to visually emphasize/annotate important text on web pages before taking screenshots or saving content

1. User clicks extension icon in toolbar. 2. Popup opens showing a 'Please rate us' link and preview image. 3. popup.js injects inject.js into the active tab via chrome.scripting.executeScript. 4. inject.js adds a mouseup event listener. 5. When user selects text and releases mouse, the selection range is processed and each text node is wrapped in a <span> with yellow background (rgba(255,216,0,.8)). 6. Highlighted text persists on the page until refresh.

Target users: General web users who want to annotate/highlight text on web pages / Users preparing annotated screenshots / Students and researchers marking important passages

The store description mentions '10+ colors to choose from' but the source code only shows a single hardcoded yellow color - this feature claim may be inaccurate or removed in v3.0.0
Homepage (web-highlighter.pdfwork.com) is not inspected and may have additional features or account requirements independent of the extension

Monetization

No paid features detected

No payment, subscription, billing, or feature-gating code found anywhere in the source. The store description explicitly states 'free'. All keyword hits for 'pro' are false positives from JavaScript prototype method names, and 'license' is from Bootstrap's MIT license header.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally with no authentication flow, no user account system, and no external API calls requiring credentials. Core functionality (highlighting selected text) works directly via content script injection with no login gate.
