WordMark

Highlight words by groups · jump between matches · custom styles · stats · import/export

Ever wished you could mark important words as you browse — and have them highlighted automatically on every page? WordMark does exactly that. Create groups of words or phrases, pick a color, and watch them light up across every website you visit. It's simple to set up and works everywhere. ✦ What you can do with WordMark 🎨 Custom highlight styles Choose from 6 styles per word: background, underline, border, text color, bold, or pulse animation. 🗂 Word Groups Organize your words by topic, project, or context. Each group has its own color and can be enabled or disabled with one click. 🌐 Site Rules Want a group to highlight only on GitHub? Or everywhere except one site? Set per-group rules using simple domain patterns. ⏰ Schedules Set which days and hours each group is active. WordMark pauses it automatically outside its schedule — no manual toggling needed. 💾 Import / Export Back up all your groups and words to a JSON file and restore them on any device in seconds. 🌍 Multilingual Available in English and Brazilian Portuguese, with more languages coming. 🎛 Fully customizable appearance Adjust the floating button size, opacity, position, and accent color. Change the panel width. Hide the button entirely and use shortcuts only. ✦ Works everywhere WordMark highlights text even inside complex web apps that use Shadow DOM — including enterprise tools like ServiceNow, Salesforce, and similar platforms that other extensions can't reach. ✦ Private by design WordMark works entirely in your browser. Your words and groups are stored locally using Chrome sync — never sent to any server, never shared with anyone. ✦ How to get started Click the WordMark icon to open settings Create a group and give it a name and color Add the words you want highlighted Browse any website — your words will light up automatically A guided tour walks you through everything on your first launch.
