Clinical Tools

Interactive calculators & scores — unit-aware, cited, embeddable.

Classic bedside medicine, rebuilt: type your values in the units you think in, watch the result land on a colored severity band, and read a short cited article around every formula. Every tool also has an Embed option — one line of HTML puts it on your own site, in light or dark.

Educational use only — these tools support thinking, they don't replace clinical judgement. More calculators are on the way; suggest one via Feedback in the footer.
