MarkMyWords

About

MarkMyWords lets you highlight multiple search terms on any webpage simultaneously, each in a distinct color — just like a physical highlighter set.

Key Features:
Multi-term highlighting — Add as many search terms as you need, each gets its own unique color automatically.

Match count badge — See exactly how many times each term appears on the page at a glance.
Cycle through matches — Click any highlighted term chip to scroll smoothly to the next occurrence on the page.

Regex support — Toggle regex mode to use powerful regular expressions for advanced searches.
Case sensitive & whole-word modes — Fine-tune matching behavior from the Settings tab.

Persistent highlights — Your search terms are remembered per tab and restored when you reopen the popup.

Works on dynamic pages — A MutationObserver ensures newly loaded content (SPAs, infinite scroll) gets highlighted too.

No data collection — Everything stays on your device. No servers, no tracking, no analytics.

Perfect for researchers, developers, students, and anyone who reads long pages and needs to track multiple concepts at once.
