Duck.ai
Duck.ai is DuckDuckGo's private AI chat. You can talk to ChatGPT, Claude, and other models in one place without creating an account. The service is free, and DuckDuckGo says it anonymizes your chats to keep conversations away from hackers, scammers, and data-hungry companies.
The product sits inside DuckDuckGo's broader privacy-first approach. Instead of routing you through a typical AI signup flow, Duck.ai opens straight into chat with model options like a Fast tier built on 5.4-nano. You can also start voice chats, generate images, and drop photos or PDF files into a thread.
It fits anyone who wants mainstream AI models without handing over personal data first. Privacy-minded consumers, students, and researchers who compare answers across providers can use Duck.ai as a single, no-cost entry point.
