AppCat routes links, files, apps, and individual windows to the right place without making you clean up the context afterward.
Rules, history, and statistics stay on the Mac. AppCat has no accounts, telemetry, or tracking. It only makes functional requests for favicons, page titles, redirects, and updates.
Problem: A work link, personal link, or deep link should not all open in the same browser session.
Outcome: Choose a browser, profile, or compatible native app from one picker.
Problem: Repeated host and URL patterns create the same routing decision every day.
Outcome: AppCat matches host, substring, full URL, or regex rules and hands the link off automatically.
Problem: Application switching still leaves you looking for the right window.
Outcome: Use Option-Tab to select a specific window, not only an application.
Problem: Finder does not always surface the editor you actually want for a known or unknown file type.
Outcome: Choose from a compatible-app picker and continue in the selected editor.
