# Duck.ai

> Private, anonymized chat with third-party AI models

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.

## Ways to pay less

- **About 17% off with yearly billing** (Annual discount): Plus is $99.99 a year against $9.99 a month, and Pro is $199.99 a year against $19.99 a month, a saving of about 17% over twelve monthly payments. Source: https://duckduckgo.com/pro

## 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.

## 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.
