Description
Sether replaces detected sensitive values with stable tokens before text reaches an LLM, then restores recognized tokens using your application’s private mapping. The MIT-licensed library supports streaming redaction, configurable detectors and integrations for AI applications. Start with fictional data and evaluate detection coverage and response quality on your own workflow. This launch is the open-source library; the hosted gateway is not yet available.
