Meta has filed a patent application for an AI that listens to your voice throughout the day, works out how it thinks you are feeling from the way you sound, and keeps a timestamped log of every read.
Each read gets pinned to the moment it happened: the time, your location, what you were doing, even how you were using your phone. Some versions in the filing would listen all day; others would check in only at set times.
None of these ships in a product today, and Meta has not announced one; a filing like this stakes a claim on an idea long before anyone commits to building it.
The application, US 2026/0182881, was filed by Meta Platforms in December 2025 and published on July 2. It names a single inventor, Lachlan Dunn, and traces back to a provisional filing from December 2024. The patent-analysis site Patentlyze flagged the filing first.
Its title pairs two ideas, emotional state analysis and real-time fitness coaching. The claims show the first is the one that matters: of the 20, the three independent ones cover emotional analysis on its own, while workout coaching appears only in the dependent claims that build on them.
