APS - Advanced Phrase Search by Diamond

APS finds and highlights unlimited words, phrases, and full regular expressions on any page at once, each in its own color. Find important words instantly, scratch unwanted items from lists, catch good prices at a glance, and much more.

No more re-running Ctrl+F over and over, or losing your search the instant you interact with the page. Build a list once — APS keeps it lit up, live, on every page you visit.

Smart, flexible matching
- Highlight any number of words and phrases simultaneously, each with its own color
- Full regex support, mixed freely with simple wildcards in a single pattern — no need to choose between them (e.g. one pattern catches both "1 bathroom" and "2 bathrooms")
- Five match modes: partial, exact, starts-with, ends-with, and full regex
- Organize terms into color-coded groups with shared defaults; override any single term when you need to
- Choose how overlapping matches resolve — longest phrase wins, or higher-priority group wins

See results at a glance
- Live match counts per term, per group, and for the whole page
- One-click navigation to the previous or next occurrence
- A toolbar badge shows your match count without even opening the panel
- A search box filters your term list instantly — built for people with dozens of groups and hundreds of terms

Built for real, messy pages
- A draggable, resizable in-page panel — not a popup that disappears the moment you click away
- Right-click any selected text on a page to add it straight into a list (or start a new group from it)
- Re-highlights automatically as dynamic pages update, without breaking the page layout

Fast and private, by design
- 100% local: no servers, no accounts, no analytics, no ads, ever
- Optional "this tab only" mode, so background tabs stop highlighting and stay light on memory and CPU
- Export and import your term lists as JSON to back them up or share them

Built for researchers and students combing long documents for key terms, developers and QA testers auditing content with regex, editors, apartment hunters scanning listings for specific amenities, and anyone who wants Ctrl+F that actually keeps up with them.

Free. Lightweight. No ads, no tracking, no nonsense — just a better way to see what matters on the page in front of you.
