UnboundChat has launched a privacy-first open-source client for Android and Windows, designed to give users complete control over their AI interactions without compromising on privacy. The application offers access to over 100 AI models, including well-known options like ChatGPT and Claude, and features advanced functionalities such as voice input and output, image uploading for analysis, and real-time web search with citations. Users can securely sync data across devices while ensuring that their encryption keys remain local, and they can delete their cloud data anytime with a single tap. This initiative is significant for the AI/ML community as it prioritizes user privacy in an era where data security is a growing concern. The platform supports various AI models and reasoning tools, enabling customized interactions through built-in and user-defined prompts.

With localization in five languages and minimal analytic use, UnboundChat is not merely a tool but a statement on user empowerment in the AI landscape.
