DuckDuckGo AI Chat
DuckDuckGo AI Chat (Duck.ai) is a free, anonymous gateway to multiple frontier-vendor models with no account required. Privacy is the whole point: your IP is stripped, prompts aren't logged, data is deleted within 30 days, and providers contractually can't train on it. The free tier offers current lighter-weight models (GPT-5.4 mini/nano, Claude 4.5 Haiku, Mistral Small, open gpt-oss), while DuckDuckGo's paid Privacy Pro unlocks frontier models. There's no API and no memory by design -- it trades continuity and automation for genuine privacy.
Claude edges DuckDuckGo AI Chat on aggregate — 87 vs 71.
Wins on reasoning depth and long-context work where ChatGPT falls apart -- the go-to choice for developers and researchers who need accuracy over speed. DuckDuckGo AI Chat still wins for buyers who prioritise completely free and anonymous -- no account or login. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
