Keyword Highlighter - Multi Highlight

Description

Highlight keywords on any website — with keyword groups, per-site rules and instant search for free. Multi Keyword Highlighter – Multi Keyword & Text Highlighter for Any Website Highlight multiple keywords at once, in different colors, on any webpage — automatically. Multi Keyword Highlighter is a fast, lightweight browser extension that finds and highlights every keyword you care about the moment a page loads, so the information that matters is impossible to miss. Think of it as Ctrl + F for many words at the same time: always on, color-coded, and organized into groups you control. ✦ Key Features - Automatic Keyword Highlighting — Your keywords are highlighted instantly as each page loads, across every website you visit. No clicking, no re-running a search. - Multi-Color Keyword Sets — Assign red, green, orange, blue, pink, or purple to each set of words and categorize information at a glance. - Keyword Groups — Organize keywords into separate groups and switch any group on or off with a single toggle, without losing your saved words. - Site-Specific Groups — Limit any group to one website. Enter youtube.com and it highlights across the entire site, including every subpage and subdomain — or enter youtube.com/subscriptions to target just that section. Leave it blank and the group works everywhere. - Instant Keyword Search — Search across all your groups at once, jump straight to any keyword, and step through repeated matches with a single click. - Six Designed Themes — Choose from Obsidian, Ember, Matcha, Abyss, Amethyst, and Rosé: six hand-tuned dark palettes built for long reading sessions. - Works on Dynamic Pages — Keeps highlighting as new content loads on infinite-scroll feeds and single-page apps like YouTube, Reddit, and X. - Never Interrupts Your Typing — Highlighting stays out of chat boxes, comment fields, and rich-text editors, so your cursor never jumps while you write. - Import & Export — Back up your keyword groups to a file and restore them in another browser, profile, or device. - Guided Walkthrough — A short built-in tour shows you the essentials the first time you open the extension. - Persistent Settings — Your keywords, groups, colors, and theme are saved automatically and restored on every visit. - Lightweight & Fast — Efficient DOM scanning with minimal performance impact, even with thousands of keywords across many groups. - Clean Modern UI — A minimal, distraction-free interface designed to stay out of your way. ✦ Who It's For Useful for anyone reading dense pages and looking for specific information fast — students and researchers working through long articles, job seekers scanning listings, recruiters reviewing resumes, marketers and analysts tracking terms across competitor sites, journalists cross-referencing sources, and shoppers comparing product specs. If you're skimming a page for particular words, it saves you the repeated Ctrl+F. ✦ How It Works 1. Open the extension and create a keyword group 2. Type your keywords separated by a space, comma, or new line 3. Pick a highlight color — and optionally limit the group to a single site 4. Click Highlight, and every match lights up instantly on every page you visit - Currently PDF files are not supported. Browsers block extensions from modifying the built-in PDF viewer, so highlighting cannot run there. ✦ Privacy Multi Keyword Highlighter is completely free, requires no account, and has no sign-in. Your keywords stay in your own browser and are never collected, transmitted, or sold. The extension requests only the minimum permissions it needs to run, and file-access permission is requested only if you choose to export a backup.
