The Medic's Knife is the answer
Every document you upload, every query you make, every draft you write gets stored on servers you don't control. Cloud tools mine your work for training data, sell usage analytics, and expose you to breaches. Offline tools run entirely in your browser. Your files never leave your machine.

Calculate weight-based drug doses from a built-in formulary, compute BMI with classification, score the Glasgow Coma Scale interactively, rate newborns with APGAR, convert between medical units including glucose, creatinine, and cholesterol, and calculate IV drip rates with 4-2-1 maintenance — all offline, all private, all yours forever.
