The Prompt Lost Its Names Before It Left the Machine
An open local tool redacted or pseudonymized legal and medical text while preserving utility in the authors’ evaluations.
Summary
An open local tool redacted or pseudonymized legal and medical text while preserving utility in the authors’ evaluations.
Redakto exposes personal-information handling through a web app, REST interface and model-context hooks that can run on modest local hardware. Evaluations on legal and medical text found downstream utility comparable to the original text across the tested strategies. That does not guarantee perfect privacy: effectiveness depends on the detector, domain and configuration, and any missed identifier could still reach the downstream model.
