Enterprise staff in retail, finance, logistics, and healthcare spend hours executing standard operating procedures across legacy ERPs, internal portals, and POS software that lack modern APIs or built-in validation guardrails. A single overlooked compliance checkbox or out-of-order submit can trigger audit fines, chargebacks, and hours of manual cleanup.

ScreenGuard solves this from pixels alone. By observing a shared browser tab through privacy-preserving client-side change detection, ScreenGuard ingests plain-English standard operating procedures (SOPs) and evaluates screen state transitions using multimodal vision intelligence.

Its deterministic StepEngine state machine validates procedural preconditions, enforces confidence gates (>= 0.70 standard, >= 0.85 high-risk), detects sequence skipping, and triggers real-time visual alerts and spoken warnings before irreversible actions are committed.

In benchmark evaluations across 16 recorded Acme Admin sessions, ScreenGuard achieved a 100.0% error detection rate across all five major procedural mistake types (skipped step, wrong order, wrong value, wrong control, premature submit) with an average spend of under $0.002 per session and zero frame disk persistence. Step tracking accuracy reached 67.9% and false alarms averaged 3.0 per correct run. ScreenGuard transforms any legacy web interface into a self-supervising, error-free workflow.
