Qwen Chat
Qwen Chat is Alibaba's free conversational app built on the Qwen model family, one of the most capable open-weight model lines in the world. The consumer app is permanently free with no obvious message caps -- web, mobile, and desktop -- which undercuts every Western rival on price. Developers can call the same models cheaply through Alibaba's DashScope API (OpenAI-compatible), though the always-free dev tier was replaced by a finite trial in 2026. Its main drawbacks are China hosting, a compliance concern for Western firms, and a consumer UX that trails ChatGPT.
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.
Qwen Chat edges DuckDuckGo AI Chat on aggregate — 87 vs 71.
Unbeatable price -- a fully free app and dirt-cheap open weights with a relentless release pace -- but China hosting caps its appeal for Western businesses. 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.
