About Cse

CSE is a Safari extension for iOS and macOS that customizes the search engine used from Safari's search bar. It detects searches on pages from Safari's default search engines, such as Google or DuckDuckGo, and redirects them to the selected engine. This approach depends on searches starting from those default-engine pages.

Pricing is not clearly stated.
