Security researchers found that Muse extracts and compiles detailed files on users' friends, family, partners, and professional contacts, Gizmodo, Mashable, and Social Media Today all reported.

The AI tool can gather information about individuals even if they do not use the Muse application itself, Gizmodo reported. Gizmodo and Social Media Today noted that the system continuously extracts personal contacts and tracks details based on direct interactions with the app. [3][4]

Meta Platforms announced Muse on September 8, 2026, as a personal AI agent designed to perform long-running tasks on behalf of users rather than answering individual queries like a standard chatbot. The assistant launched in the United States across iOS, Android, and web platforms. [10]
