Blocks ads and trackers in Safari, shows you who is tracking each page, and sets up in one click from the Mac App Store.
No. Safari's Intelligent Tracking Prevention limits how trackers follow you between sites, but it doesn't remove ads. Safari supports ad blocker extensions instead, which you install from the Mac App Store and switch on in Safari Settings.
It uses Safari's native content blockers, so blocking runs inside Safari itself, quickly and without reading your pages. Alongside the block lists, the extension adds what content blockers can't do on their own: a Tracker Map that names the companies watching each page, a live Privacy Score for every site, and handling for cookie and anti-adblock walls.

Safari menu, Settings, then Extensions. Select AI CleanWeb there to turn it on or off, or click its shield in the toolbar for more options.
Does it slow Safari down?
No. Blocking runs in Safari's native content blocker engine, and pages usually load faster because ads and trackers never download.
AI CleanWeb is also an extension for Chrome and Firefox, and an app that blocks ads inside every app on iPhone and Mac.
