Features
Anonymous model access
Chat with third-party AI models through DuckDuckGo, which anonymizes the requests and keeps them out of AI training.
Private chat sharing
Encrypted links share an entire chat or a single answer for reading or continuing, expiring automatically after 48 hours.
Advanced models on subscription
A DuckDuckGo subscription unlocks advanced Duck.ai models and adds a VPN for up to five devices and other privacy services.
Fire Button clearing
Duck.ai chats live in the browser, and the Fire Button clears them, along with any shared links, in one tap.
What users say
Pros
- Several big-name chat models are free to try without creating an account.
- Chats remain anonymous and excluded from third-party AI model training.
- Image generation runs directly inside the chat window from text descriptions with prompt-controlled dimensions.
Cons
- The free default models often get the first answer wrong, forcing a retry or a model switch.
- On phones it lives inside the DuckDuckGo browser, with a cramped layout and flaky sync.
- Prompts still pass through external servers operated by third-party model providers.
