How to Use Duck.ai (formerly DuckDuckGo AI Chat) in 2026: Step-by-Step Guide
DuckDuckGo's rebranded Duck.ai — a free, private AI chat interface offering multiple AI models, with an optional paid tier for premium models, without storing conversations or tracking users.
Duck.ai (rebranded from "DuckDuckGo AI Chat" after exiting beta in 2025) lets users chat with AI models — including GPT-4o mini, GPT-5.4 nano/mini, Claude 4.5 Haiku, Llama 3.3 70B, Mistral Small 3 24B, gpt-oss-120b, and Gemma 4 31B — for free, with no account required and no conversation history saved by default. DuckDuckGo acts as a privacy intermediary: chats route through DuckDuckGo's servers, which strip identifying information before passing queries to AI providers, and DuckDuckGo contractually prohibits providers from training on these conversations. Unlike the original free-only version, Duck.ai now has a genuine paid tier: subscribers to DuckDuckGo's Plus plan ($9.99/month or $99.99/year, bundled with a VPN and identity-protection tools) unlock GPT-5.4 and Claude Sonnet 4.6 in Duck.ai, while Pro subscribers ($19.99/month or $199.99/year) additionally get Claude Opus 4.8, higher reasoning effort, and 2x the usage limits of Plus. The free tier remains fully usable with no sign-up. For anyone who wants to explore AI assistants — from casual free use to premium frontier models — without generating a permanent data footprint, Duck.ai remains one of the most friction-free, privacy-forward options available.

- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show Duck.ai (formerly DuckDuckGo AI Chat) what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
