Objective UX task analysis, powered by classic HCI

Keystroke-Level Model Analyzer helps designers evaluate web task flows with classic HCI rigor. Inspired by Card, Moran, and Newell, this Chrome extension records a known task and turns it into an auditable KLM estimate: expert time, operator counts, bottlenecks, and step-by-step trace.

I built Keystroke-Level Model Analyzer for designers who want a more objective way to analyze UX flows. KLM is a classic HCI method, but using it manually can feel slow and disconnected from modern product work. This extension lets you perform a real web task and turns the interaction into an auditable estimate: time, operators, bottlenecks, and trace. The goal is not to replace judgment. It’s to give designers a sharper artifact for discussing flow efficiency, tradeoffs, and where interaction cost actually comes from.
