Highlight Plus: Instant, Privacy-First Keyword Highlighting for Enhanced Productivity

Stop drowning in content. Highlight Plus is the essential utility for students, researchers, and professionals who need to perform content scanning, study, and compare large volumes of text faster. By instantly making your important words stand out on any webpage, Highlight Plus transforms long articles and complex documents into actionable, scannable content. It is engineered for speed, privacy, and seamless performance, ensuring your focus remains on the information, not the tool.

The Trust Factor: Zero Data Collection Guarantee

Highlight Plus is designed around your privacy. All processing happens locally in your browser using secure content scripts—no page text is ever collected, transmitted, sold, or shared with external parties. The extension reads page text only to render temporary on-page highlights, preserving your browsing privacy completely. Settings (such as the keyword list and on/off state) are saved securely using browser storage on your device for functionality and convenience.   

Core Productivity Features

The extension features are concise, powerful, and built for flexible workflows:

✓⃝  ✨ Custom Keyword Manager: Easily add, edit, and bulk paste keyword lists. Manage complex research or study topics quickly and flexibly.
✓⃝  ⚙️ Smart Dynamic Tracking: Highlights stay locked in place and accurate, even as content updates dynamically on modern, complex websites and Single Page Applications (SPAs).
✓⃝ ⚡ Lightweight & Universal: Designed with minimal styling to keep page layouts intact and readable. Works across virtually all websites and long, content-heavy browser tabs.
✓⃝  ⏯️ Toggle Control: Instant toggle to enable or pause highlighting on all active tabs at any time, giving you immediate control over your environment.
