Duck.ai
DuckDuckGoDuckDuckGo's anonymous AI chat surface, on the web and inside the DuckDuckGo browser, letting users chat with third-party models without an account. It strips personal metadata including the IP address before prompting a provider, and conversations are not used for training. The proxy sits in front of model APIs DuckDuckGo does not operate.

Adoption
3 low confidenceBacked by DuckDuckGo's large user base and built into its browser, but no Duck.ai-specific usage figures are published. The level is a conservative reading of that reported reach until an active-user count is disclosed.

Capability
2 high confidenceAnonymizing multi-model chat proxy, strong on privacy and model choice but with a deliberately minimal surface: no RAG, plugins, agents or multimodal generation. That keeps it lower-tier among chat UIs, though paid tiers reach Claude Sonnet 4.6, Mistral Small 4 and, at the top, Claude Opus 4.8 with higher reasoning effort.
