Private AI chat from the makers of DuckDuckGo
Choose among several leading AI assistants from a single interface instead of juggling separate apps.
Start chatting without signing up, handing over an email, or creating a profile.
Chats are designed to stay detached from your identity rather than being tied to an ad profile.
Accessible alongside the search engine and browser that already block trackers and cookie pop-ups.
