What is Duck.ai?

Duck.ai is DuckDuckGo's answer to AI chat for people who do not want their conversations stored, profiled or used for training. You open the page and start talking — no account, no sign-up — with a choice of models from OpenAI, Anthropic, Meta and Mistral. Chats are anonymised before reaching the model providers, and DuckDuckGo states prompts are never used to train models.

The interface keeps things deliberately simple: text chat, a model picker, optional web answers and a fire button that wipes the conversation instantly. It will not remember you between visits, and that amnesia is the feature. For quick questions, drafts and lookups where privacy matters more than power features, Duck.ai fills a gap none of the big assistants seriously compete for.
