Arc is based on the same Chromium engine as Chrome and Edge, so it works with Chrome extensions. That also allows them to focus on life-enhancing features for the Internet, including tools for customization such as Boosts and Zaps.

Note that Bookmarklets are not available. For example, to clip recipes for meal planning with Plan to Eat, you would need to copy the URL to a separate Chrome window and use the Add to PTE bookmarklet there.

Until such apps offer their Web Clipper as a Chrome Extension, you would have to create an Arc Boost that injects a Script that implements the necessary JavaScript from the bookmarklet (which I’m exploring).
