Highlighter Extension

Highlight multiple words and keywords on any page: a highlighter extension that counts matches per tab.

Highlight multiple words and keywords on any page, all at once. You type or paste a list of terms, switch it on, and the whole page gets highlighted in one pass instead of one word at a time. One thing to get straight before you install: you don't drag the mouse over text to colour it, and there are no notes or annotations here. This highlighter extension keeps a keyword list and finds every term wherever it shows up. If what you want is a manual marker pen for the web, this is the wrong tool, and you're better off knowing that now. ⚡ What the highlighter extension does 🔹 up to 50 keywords in one list, all highlighted in the same pass 🔹 a match count on the toolbar icon, per tab, before you open anything 🔹 matches inside collapsed sections, which Ctrl+F walks straight past 🎯 and the parts people notice on day two 🔹 every hit listed in the popup; one click scrolls the page to it 🔹 keyboard jumps forward and back through the matches 🔹 a keyword highlighter that runs locally: no account, no sync, no server 🚀 The first thirty seconds 1️⃣ install the highlighter extension and pin its icon 2️⃣ open the popup, paste your keywords one per line 3️⃣ flip the switch, and the page is highlighted 4️⃣ move between hits from the list or with the keyboard ⌨️ shortcuts Ctrl+Shift+F opens the popup, turns highlighting on and drops the cursor into the keyword list; Ctrl+Shift+K goes to the next match, Ctrl+Shift+H to the previous one. On macOS all three use Control. Rebind them at chrome://extensions/shortcuts if they clash with something you already use. 🧩 It doesn't break the page Most tools of this kind wrap every match in an extra element, which shifts the layout, upsets React and Vue apps, and on a long page turns scrolling to treacle. This keyword highlighter paints through the browser's own CSS Custom Highlight API, so the page keeps the markup it already had. 🔧 That is why the highlight extension survives dashboards, log viewers, web mail, issue trackers and single-page apps that redraw themselves while you read. 🔎 the badge does the triage Ten tabs of search results, or CVs, or vendor docs. The icon tells you which of them carry your keywords and how many times, so you close the empty ones without reading a line. Browser search can't tell you anything about a tab you haven't opened yet. 📚 The text that hides Long docs, FAQ blocks, spec pages and issue threads keep half their content folded away. Matches in collapsed and off-screen content still get counted, and one click takes you there with the section opened. Tick "show hidden" and you see the whole page rather than the visible slice of it. 👥 who keeps this highlighter installed 🔹 recruiters who highlight a shortlist of tool names across fifty profiles 🔹 engineers chasing error codes through logs and stack traces 🔹 analysts checking a 60-page report for a handful of entities 🔬 and the quieter half 🔹 students marking keywords before an exam 🔹 lawyers and journalists reading long documents for specific names 🔹 anyone who has pressed Ctrl+F six times on the same page 🔒 Privacy, briefly Your keywords live in your browser's local storage and nowhere else. No network requests, no account, no analytics, nothing to opt out of. Delete the list and it's gone. 🧭 where this keyword highlighter stops 🔹 one keyword list, shared by every site, in one highlight colour 🔹 literal substring matching, so "art" lights up inside "start" too 🔹 the popup interface is in English for now 📄 Chrome's own PDF viewer and Google Docs paint their text onto a canvas, and no extension on the store can highlight text that is drawn as pixels. 💡 Two things worth knowing Whole phrases beat single syllables, because short keywords turn a page into confetti. And if part of a page stays unhighlighted, reload the tab once: some sites keep building content after the browser has already called the page finished. 🛠️ Where this highlighter for websites runs Chrome, Edge, Brave, Opera and the other Chromium browsers, on Windows, macOS, Linux and ChromeOS. Frames and embedded documents get searched as well, so a page built from several sources comes back as one list of matches. 📬 no options screen to learn, no onboarding to sit through: the popup is the whole of this highlight tool, and the keyword list inside it is the only thing you ever configure. Bug reports and feature requests reach one developer, who reads them.
