WSUP AI is a hosted site for chatting with AI characters in a browser, with nothing to download: 2,065 characters across eight tags, plus search, Favorites and a form to build your own. No price, plan or payment appears on the page. Note before using it: the content filter loads set to "Unfiltered" with no age check, and the largest tag, Fan / Unofficial, holds user-created characters based on living people and copyrighted fiction.
