Grablo Spot is free AI NVR software for the cameras you already have. It records straight to your own machine and sorts every person and vehicle it sees into cards. Find anyone by face, appearance, plain text ("a person in a yellow shirt"), or a partial license plate, then follow them across every camera. Works with IP cameras, NVRs (RTSP/ONVIF), and USB webcams on Windows, macOS, Linux, and Raspberry Pi. Video is stored only on your device. No credit card, no camera limit, every feature free.
