About

Builderlog AI Workflow Readiness Check is a free, browser-only scorecard for solo operators and small teams choosing a first AI-assisted workflow. It checks whether the work is already repeated, whether inputs are stable, whether a person can review the result, and whether failures stay reversible. The result estimates observed monthly work at stake without promising savings, ROI, or safety. No signup is required and answers remain in the browser. A worked example and free workflow files make the recommendation inspectable before any paid next step.
