Highlight Keywords: Auto-Highlight Word Lists

Automatically highlight your saved keywords and phrases on any webpage, with custom colors and readable contrast. Data stays local.

Type your keywords once. Names, ticket IDs, product terms, whatever you scan for all day. From then on they light up on every page you open, in colors you can actually read. WHY THIS ONE Most highlighters paint a yellow box and stop there. On a dark site like Slack, yellow behind light text is unreadable. Highlight Keywords picks black or white text automatically for every color, so matches stay clear on any page theme. And it colors your words without changing the page underneath, so it stays smooth inside busy web apps like Slack, Gmail, and Notion instead of tripping them up. WHAT IT DOES - Highlights your saved words automatically as pages load, including infinite scroll and chat apps - Color-coded lists with icons and looks: solid fill, highlighter, underline, colored text, or dim (fade the noise instead of highlighting it) - Counts everywhere: a badge on the toolbar icon, per-list counts in the popup, colored markers along the page edge, and an on-page overview panel - Desktop alerts: any list can notify you the moment it matches a page - Click a highlighted word to copy it, with a small spark so you know it worked - Highlight inside PDFs with the built-in PDF viewer (Pro) - Insights: a private, on-device match history by day, site, and list (Pro) - Share any list as a link or file; adding it takes one click - Whole-word matching by default, regex support with a visual builder, and fuzzy matching that forgives one typo per word (Pro) - Paste a whole roster: duplicates are removed and shown to you - Right-click any selected text to add it to a list - Site rules: disable on chosen sites, or highlight only where you want - Remote lists from Google Sheets, Pastebin, plain URLs, Notion, or Airtable (Pro) - Keyboard shortcuts to jump between matches, and to turn highlighting on or off - Light and dark mode, following your system automatically - Automatic backups, import and export, and optional sync across computers PRICING Free: 2 lists, 200 words each, everything else included, forever. Lifetime Pro: one payment, no subscription. Unlimited lists and words, sync, fuzzy matching, desktop alerts with an optional sound, remote lists, and every future Pro feature. Try Pro free for 14 days inside the extension: no card, and when the trial ends the free plan keeps working with everything you made intact. PRIVACY Your lists stay in your browser. No account, no tracking, no ads, and it never changes the links on a page. The only network requests are ones you ask for: loading a remote list you configured, or verifying a license key you bought.
