Highlight Keywords: Auto-Highlight Word Lists

About

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.

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,
  box, 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, with a position readout
- Light and dark mode, following your system automatically
- Automatic backups, import and export, and optional sync across computers
