KEEPER is part of HADES.

An R package for reviewing patient profiles for phenotype validation.

• Extracts patient level data for a) a random sample of patients in a cohort or b) patients in a user-specified list and formats it according to the KEEPER principles.

• Supports review of patient profiles by humans through an interactive Shiny app.

• Supports review of patient profiles by large language models.
