What is Duck.ai?
Duck.ai is DuckDuckGo's privacy-focused front end for chatting with third-party AI models — including OpenAI's GPT, Anthropic's Claude, Mistral, and open models hosted by Tinfoil.sh — without creating an account or having your identity tied to the conversation. DuckDuckGo strips identifying metadata like your IP address before the prompt ever reaches the underlying model provider.
The core pitch is what it doesn't do: DuckDuckGo states it doesn't store your chats, and conversations aren't used to train the underlying models, either by DuckDuckGo or the model providers themselves. That makes it a way to use mainstream AI chat models without the usual account-based data trail that comes with using them directly.
The free tier includes access to several models at no cost with no sign-up. A paid Plus subscription unlocks additional, more capable models on top of the free set. It's accessible from any browser and also ships as part of DuckDuckGo's mobile apps on iOS and Android.
