What is Duck.ai?

Duck.ai is DuckDuckGo's chat service for holding private conversations with AI models from providers such as OpenAI, Anthropic and Mistral AI. DuckDuckGo strips identifying metadata before a prompt reaches the provider, keeps chat history on your device by default and says chats are not used for training. It is free with a daily limit, and the paid DuckDuckGo subscription adds more advanced models and higher limits.

Duck.ai has a free plan. Paid plans start at $9.99 per month, or $99.99 per year (DuckDuckGo Plus). See every plan

Good for

  • People who want to use mainstream AI models without an account
  • Privacy-minded users who do not want chats used for model training
  • DuckDuckGo browser users who want an assistant built in

Worth knowing

  • Free use has a daily limit, and the most advanced Claude and GPT models are reserved for Plus and Pro subscribers.
  • Advanced models cannot be bought on their own: the subscription bundles them with DuckDuckGo's VPN and identity services.
  • The subscription is sold only to residents of the US, UK, EU and Canada, and its VPN and identity features work only in the DuckDuckGo browser.
  • There is no standalone app: outside a web browser, Duck.ai is built into the DuckDuckGo browser for iOS, Android, Mac and Windows.

Key features

Anonymized chats
Metadata such as your IP address is removed before a prompt reaches the model provider, so requests appear to come from DuckDuckGo rather than from you.
Choice of models
Free models come from Anthropic, Mistral AI and OpenAI, plus two open models hosted by Tinfoil. Subscribers add more advanced Claude and GPT models.
Chat history kept on your device
Recent chats are saved locally by default, up to 5 can be pinned, and the Fire Button deletes the rest. Optional Sync & Backup stores chats end-to-end encrypted.
Image creation
Select New Image, describe what you want, then refine the result with follow-up prompts. A daily limit applies, with higher limits for subscribers.
Voice chat and dictation
Speak with an OpenAI voice model over an encrypted relay, or dictate a prompt for up to 5 minutes per session. Audio is not kept after the session ends.
Image and PDF uploads
Some models accept image and PDF uploads, with PDF limits of 15 pages on Free, 35 on Plus and 50 on Pro. Spreadsheets are not supported.
