I am delighted to announce the project that provides the core PII and PHI redaction capabilities is now open source! Introducing Phileas, the PII and PHI redaction engine! Phileas is now available under the Apache license on GitHub.

As ChatGPT starts being used in applications that contain sensitive information like PII and PHI, we have to be careful to protect the PII and PHI from being transmitted to OpenAI’s API. We want to prevent our users and applications from sending sensitive information to third-parties.
