DuckDuckGo AI Chat is a web-based anonymous AI chat tool designed to provide users with a secure and privacy-protected chat experience. It integrates multiple popular AI models, such as GPT-4, Claude 3, Llama 3.3, and Mistral Small 3, allowing users to interact with these models without revealing personal information. The product emphasizes privacy protection; it does not save user chat logs or use conversation content for AI training. Its main advantages are anonymity, privacy protection, and multi-model support, making it suitable for privacy-conscious users. DuckDuckGo, a well-known privacy-focused search engine, further expands its application in the AI field through this product, positioning itself as a privacy-first AI chat service, currently offered free to users.
