The toolkit

Built to make the evidence usable.

A reference is only worth so much without tools to put it to work. Codex ships the analyzer, the calculator, the comparison engine, and the marker reference — every tool designed around the same evidence-first methodology that backs the grades.

Interactive tools 5
References & frameworks 4

Every tool is educational — interpretation, math, and reference, never dose recommendations, protocols, or vendor links. See standards for the editorial posture and the Codex Scale for how the grades work.
