WorldLens helps people avoid leaving belongings behind. In the morning you photograph everything you carry and it becomes a checklist. When you're back you photograph again, and WorldLens compares both photos and shows what came back, what's missing, and what it can't tell, with evidence and a confidence level for every item and boxes drawn on what it found.

Every "missing" verdict is re-verified against the photo before it alerts you, which cuts false alarms. Users can correct mistakes and the corrections are fed into future prompts. It warns you if a usual item isn't in your morning photo, keeps a history you can filter and delete, and also compares any two photos of the same place. No tags or hardware are needed, just a camera.
