Signal Highlighter: Highlight Multiple Keywords

Automatically highlight multiple keywords and phrases on web pages. Reuse profiles, navigate matches, and spot missing checks.

Signal Highlighter is a multiple keyword highlighter for Chrome that helps you find and highlight words or phrases on web pages—all at once. Create reusable profiles for job searches, research, product comparisons, reports, documentation, and other workflows where important details are easy to miss. Group related keywords by color, switch profiles as your task changes, and review long pages without repeating the same searches. Use Signal Highlighter to scan job listings for salary, remote work, sponsorship, and requirements; review research and documentation; compare product pages; or check reports for expected terms and warnings. 🔎 HIGHLIGHT WHAT MATTERS • Highlight multiple keywords and phrases at the same time • Choose whole-word, phrase, contains, case-sensitive, regular expression, or fuzzy matching • Navigate between highlighted results without repeatedly using page search • See how many matches appear and spot expected checks that are missing 🗂️ REUSE YOUR SETUP • Save keywords in reusable profiles for different tasks • Organize signals into color-coded groups for matches, checks, and warnings • Start with a ready-made Starter Pack or create your own profile • Import existing lists from Highlighty, Highlight This, TXT, or CSV • Export your configuration as a portable backup 🌐 REVIEW MORE EFFICIENTLY • Apply the same profile across related pages • Review selected open tabs using one profile • Compare keyword matches across pages in a single report • Run highlighting only on selected websites when needed • Exclude specific websites from a profile 🔒 LOCAL-FIRST PRIVACY Core highlighting works locally and does not require an account.
