Last Seen gives your home a memory, and it’s built for smart glasses. Your glasses already see where you put things down. Last Seen turns that first-person video into a record of where every movable thing was, when, and whether it moved. No tags on anything, no cameras on the walls. You ask out loud, “where did I leave my car keys?”, and you get three things: the answer in a sentence (“kitchen counter, and before that the hook in the hallway”) the actual frame with SAM 3.1’s mask on the keys a short clip of that moment, tracked with SAM 3.1 video Ask what changed and you get every item that moved, from where to where, split by how sure it is. For the demo I filmed two walk-throughs of my home, 35 minutes apart, on a phone held at eye level as a stand-in for glasses, and moved five things in between. It found all five and reported nothing that stayed put as moved.
