Duck.ai
Duck.ai is DuckDuckGo’s privacy-oriented AI chat product. It is a useful benchmark for separating account and network identifiers from an upstream model provider.
Privacy model
DuckDuckGo says it removes identifying metadata before forwarding a request, does not store chats, and contracts providers not to train on the chats or retain them beyond 30 days, subject to limited safety and legal exceptions.
Its selected Tinfoil-backed models are labeled as offering zero provider visibility. That designation should not be generalized to every model or ordinary proxy route.
Lesson for the venture
A proxy is a meaningful minimization layer, but the ordinary model provider can still receive prompt plaintext. Do not market multi-provider routing as confidentiality. Private AI routing identifies the narrow, honest uses for an identity-content split.
