What is Duck.ai?

Duck.ai is the AI chat service from DuckDuckGo, the privacy-focused search company. It lets you talk to popular AI models from companies such as OpenAI, Anthropic and Mistral through one simple interface, without creating an account. DuckDuckGo sits in the middle as a proxy, so the model providers see the request coming from DuckDuckGo rather than from you.

The service started in 2024 as DuckDuckGo AI Chat and was renamed Duck.ai when it left beta in March 2025, gaining its own domain, web search and locally stored recent chats. In September 2025 DuckDuckGo added stronger models to its paid subscription, and in March 2026 it split that subscription into Plus and a new Pro tier with higher limits and the most capable reasoning models.

What makes Duck.ai different is its privacy stance rather than raw capability. DuckDuckGo says it does not store your prompts or use them for training, chat history stays on your device, and it has agreements with providers to delete data. That makes it a sensible everyday assistant for people who want AI help without building a profile with a big tech company.

Key features of Duck.ai

Who is Duck.ai best for?

  • Privacy-conscious users who want help from top AI models without an account, tracking or chats being used for training.
  • DuckDuckGo users because AI chat is built into the search engine and browser they already use.

Duck.ai pros and cons

Pros

  • Usable for free with no account or sign-up
  • Strong privacy protections and no training on your chats
  • Several model providers in one interface
  • Paid plans bundle a VPN and identity protection

Cons

  • Free models are smaller and less capable than flagship models
  • Fewer power features than ChatGPT or Claude, such as agents or deep project workspaces

  • No API for developers

How to get started with Duck.ai

  1. Go to duck.ai or open the Duck.ai tab in the DuckDuckGo browser or search page.
  2. Pick a model from the model menu; try a couple to see which you prefer.
  3. Ask your question or upload a file, and turn on web search for current topics.
  4. Pin useful chats, and use the Fire Button when you want to clear history.
  5. Upgrade only if you hit limits or need stronger models.

Tips to get better results from Duck.ai

  • Use free models for simple tasks and paid reasoning models for hard ones.
  • Remember chat history lives on your device, so export or copy important answers you need elsewhere.
  • Avoid pasting highly sensitive data anyway; privacy protections reduce risk but do not remove it.

Duck.ai vs alternatives

Duck.ai is best compared with mainstream assistants such as ChatGPT and Claude. Those offer more features, including memory, projects, agents and coding tools, but they need an account and keep your history on their servers. Duck.ai gives you some of the same underlying models with fewer extras and much stronger anonymity.

For research with citations, Perplexity is more powerful, while Kagi offers a paid, privacy-minded search engine with its own AI assistant. If you mainly want many models in one place, Poe has a much larger catalogue but is not built around anonymity. See all best chatbots & assistants tools.

Our verdict: is Duck.ai worth it?

Duck.ai is the easiest way to use well-known AI models privately and for free. It is not the most capable assistant, but for everyday questions and writing help it is very good, and the paid plans are reasonable if you also want DuckDuckGo’s VPN and identity tools. Choose it if privacy matters more to you than advanced features.
