Show HN: PrivateOS: An AI agent that runs on your phone (private-os.vercel.app)

PrivateOS has introduced a groundbreaking AI agent that operates entirely on smartphones, addressing significant concerns surrounding data privacy in traditional cloud-based AI systems. Unlike typical AI assistants that require uploading sensitive information to external servers, PrivateOS ensures that all data processing—ranging from emails and messages to calendars—occurs locally on the device. This localized approach means users' personal information is secure and never leaves their phone, with only anonymized prompts sent to the cloud when deeper reasoning is necessary. This technology is particularly relevant for professionals in privacy-sensitive roles, such as lawyers and healthcare executives, who face strict compliance regulations and cannot transmit client or patient data to cloud-based AIs. By autonomously managing tasks like drafting replies, scheduling meetings, and summarizing daily agendas, PrivateOS enhances productivity while maintaining rigorous privacy standards. As the service is currently limited to just 100 initial users, its rollout represents a potential shift in how AI can integrate into workflows without compromising personal data security.
