About

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.

In-Depth Review

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.
