Ergonomic assessments usually need an expert on-site and take weeks, so risky tasks rarely get checked until someone's hurt. KnowErgo scores risk from a short video instead, tracking posture frame by frame against six validated methods: RULA, REBA, NIOSH, WISHA, Snook, and MAC. It scores the whole clip, not just one snapshot, so you see exactly when a task crosses the action limit, then opens a corrective action and schedules a re-assessment.
