Duck.ai

Duck.ai platform overview and privacy-first AI architecture

Duck.ai (accessible at duck.ai or duckduckgo.com/chat, developed by DuckDuckGo) is an anonymous, privacy-focused artificial intelligence chat aggregator and conversational interface. Designed for privacy-conscious users, researchers, and journalists, Duck.ai enables access to leading commercial AI models without tracking personal identities or storing chat histories.

Unlike standard AI platforms that mandate account registration, email verification, and phone numbers, Duck.ai acts as an anonymizing proxy. User prompts are stripped of metadata (IP addresses and browser fingerprints) and routed through DuckDuckGo’s encrypted servers before reaching model providers, with strict contractual agreements preventing models from training on user queries.

Core privacy features and model selection

Duck.ai provides tools for anonymous conversational AI:

• No account required: Start chatting immediately without creating an account, entering an email, or sharing credit card details.
• Metadata stripping: Encrypts requests and strips IP addresses, preventing third-party model providers from profiling users.
• Contractual zero-training: Legally binding agreements with model providers ensure user conversations are never used for model training.
• Model switching: Easily toggle between leading models including Claude Haiku/Sonnet, GPT-5 mini, Mistral, and Llama.
• Local chat storage: Conversation threads are stored purely in local browser memory and can be cleared with one click.
• DuckDuckGo Privacy Pro integration: Bundled with DuckDuckGo’s VPN, Identity Theft Restoration, and advanced AI quotas.
