Duck.ai
Free private AI chat from DuckDuckGo: multiple models, anonymized chats, no account needed.
About
Duck.ai is DuckDuckGo's free AI chatbot, integrated into its search engine and available standalone. It offers a rotating lineup of models from OpenAI, Anthropic, Mistral, and Meta, so users can compare responses across providers. DuckDuckGo proxies requests so IP addresses are not shared with model providers, chats are anonymized and never used for training, and history is stored locally on the device. In 2026 Duck.ai added image generation and real-time, privacy-protected voice chat.
The service left beta in early 2025 with models like GPT-4o mini, o3-mini, Llama 3.3, Mistral Small 3, and Claude 3 Haiku. In September 2025 DuckDuckGo's $9.99/month subscription (bundled with VPN, personal-info removal, and identity-theft restoration) gained access to heavier models including GPT-5, GPT-4o, Claude Sonnet 4, and Llama Maverick, while the free tier keeps lighter models with daily limits. No account is required for the free tier, which makes it one of the lowest-friction private AI chats available.

Trust score — 8/10
Scored 8/10 (verified tier, metrics-v1). Evidence: left beta early 2025 with multi-provider model lineup (TechRadar, Product Hunt); $9.99/mo subscription added GPT-5 and Claude Sonnet 4 access Sept 2025 (TechCrunch, PCWorld); DuckDuckGo is an established privacy company; voice chat and image generation added in 2026 with Similarweb-tracked growth. Strengths: real privacy architecture, no-account free tier, credible vendor. Docked for: (1) free-tier models are lighter with daily limits; (2) privacy guarantees rest partly on vendor policy rather than full cryptographic attestation. License: proprietary.
