SmartCheck is a browser-based AI counting tool built by a student team at Tokyo University of Science. Upload a photo and tap three examples of what you want to count. SmartCheck detects similar objects and shows their positions, so you can review the result, manually correct mistakes, and save it. You can try 10 counts without signing in before choosing a paid plan. It is designed for trying photo-based counts of materials, parts, products, and crops without preparing object-specific training data first. Results depend on the objects and photo conditions; complex shapes, holes, and angled photos may cause missed or duplicate detections. Submitted by the maker.
