LineCheck — Demo video

LineCheck Vision is a heads-up AR kitchen display and real-time operations ledger designed for commercial cook lines. The Problem: Commercial line cooks work with gloved hands amidst raw proteins, wet line stations, and sanitation chemical solutions. Stopping mid-prep to tap tablet screens or manually calculate yields introduces serious cross-contamination hazards, breaches food safety protocols, and stalls ticket velocity. The Solution: LineCheck Vision bridges culinary operations and spatial AI by simulating a Meta Ray-Ban heads-up display synchronized with an active prep ledger. By pairing Meta SAM 3.1 zero-shot segmentation with WebMCP tool execution: - Line cooks inspect hotel pans, verify pars, and evaluate protein trim yields (such as Salmon and Beef Tenderloin) completely hands-free via HUD reticles. - Real-time computer vision segments container boundaries and estimates fill levels in the cook's direct line of sight. - WebMCP tools (`record_waste`, `calculate_yield`, `tare_scale`, and `verify_pan_depth`) automatically log actionable prep data to the kitchen ledger without the cook touching a screen. By removing screen friction from the prep board, LineCheck Vision protects kitchen sanitation standards while giving management real-time yield and inventory visibility.
