Page Highlighter

Highlight text on any page — it's saved and restored on revisit. Browse, search, and group all your highlights in one place.

You read something important online — a key sentence in an article, a definition in a tutorial, a quote you want to remember — and a week later you can't find it again. Page Highlighter fixes that. Select any text on any site, pick a color, and the passage is saved instantly. The next time you open the same address, your marks come back on their own, exactly where you left them. No accounts, no setup, no waiting. Think of it as a marker pen for the entire web, with a tidy notebook attached. ✨ Features 🖍️ Mark any text on any site with one click 🎨 Five color choices to organize what you save (yellow, green, blue, pink, orange) 🔁 Saved marks are restored automatically when you revisit a URL 🗂️ A dedicated library that lists every annotation you've ever made 🔎 Built-in search across all of your saved passages 📅 Group your collection by day or by site, or view everything as a flat list 📖 Long quotes collapse neatly with a "Show more" toggle so the list stays readable 🗑️ Remove any saved annotation with a single click 🌗 Light and dark mode, matched to your system theme 🌐 Works on any URL you open 🎯 How it works 1. Select text on a site. A small floating "Highlight" button appears next to your selection. 2. Click it and pick a color from the palette. 3. The passage is marked on screen and saved locally on your device. 4. Open the same address later — your marks are re-applied automatically. 5. Click the toolbar icon any time to open your library and browse, search, or group every saved piece in one place. 🔒 Privacy Your notes belong to you, and they stay with you. 🛡️ 100% local. Everything is stored on your own device using the browser's local storage. 🚫 No accounts. No sign-up, no login, no email required. ☁️ No cloud sync. Nothing is uploaded anywhere. 📡 No network requests. The extension never talks to any server. 👀 No tracking, no analytics, no ads. 🔑 Only one permission is requested: storage, so your marks can be saved on your device. The content script runs on websites so that you can select and save text everywhere you read — but nothing you view ever leaves your browser. What you read, what you mark, and where you mark it are completely private. 💡 Use cases For students and learners: capture definitions, formulas, and key arguments while studying online textbooks, lecture notes, MDN docs, or course material. Come back days later and your study notes are waiting on the screen. For researchers and writers: gather citations and key passages from articles, papers, blog posts, and reference material. Use different colors for sources, quotes, counter-arguments, and ideas to develop later. For knowledge workers: capture the important sentence in a long company doc, internal wiki, or specification. Skim faster on the second pass — the parts that matter are already colored. For news and longform readers: mark the paragraph that actually answers your question in a 5,000-word piece, so the next time the topic comes up you can find it in seconds. For code review and documentation: pick out the exact line of a release note, RFC, or API reference you need to remember. Re-open the URL tomorrow and your annotation is still there. For everyday browsing: save the one usable tip in a how-to guide, the exact step in a recipe, the best line of a review, the part of an FAQ that finally answered you. Anywhere there's text worth keeping, you can keep it. 🚀 Why you'll love it ⚡ Instant — select, click, done. No dialogs, no friction. 🎨 Color-coded — five tones give you a simple, visual way to sort what matters: ideas, sources, follow-ups, quotes, questions. 🧠 Memory that follows the URL — your marks re-apply themselves the next time you visit, even if small things on the layout changed. 🗂️ One library for everything — a single screen collects every annotation from every site, searchable and groupable. 🪶 Lightweight — opens fast, stays out of your way until you select text. 🔐 Private by design — no accounts to create, no data shared, no servers involved. 🌍 Works everywhere — articles, blogs, documentation, study sites, internal portals, anywhere there's readable text in a Chromium-based browser. A few practical touches that make daily reading nicer: the floating button only shows up when you actually select text, the library is comfortable to scan in both light and dark themes, long passages tuck themselves away behind a "Show more / Show less" spoiler so one huge quote doesn't drown the rest of your notes, and deleting an item you no longer need is a single click — no confirmations, no menus to dig through. This tool is built for people who use the web as a reading platform. If you spend your day moving between articles, documentation, learning material, and reference resources, it is a quiet helper that turns reading into a place you can come back to. The internet becomes a little less disposable. Knowledge you collected last week is one revisit away — still marked, still searchable, still yours. 👉 Get started Install the extension, open any address, select a sentence you want to keep, and pick a color. That's it. Your first save is done, your library is started, and from now on the web remembers what you cared about — privately, locally, and instantly. Happy highlighting.
