Keywords Highlighter

Mark the words that matter. Keywords Highlighter scans any page for your terms the moment you hit On — every match lights up in colour, grouped by category, so you spot what you're looking for without reading line by line.

Set it up once. Use it on every page.

Create categories for any terms you care about, give each a colour, and add as many words or phrases as you need. One click and the whole page is marked up.
