Redact sensitive documents on your computer, or redact text at scale inside your own pipelines.
On your desktop
PC-based redaction for small law firms, solo practitioners, and clinics. Redact .txt, .docx, and .pdf files on a single Windows computer, with no server to stand up and nothing sent to a cloud service. Everything runs on your computer.
In your pipelines
The turnkey, self-hosted REST API redacts PII and PHI at scale inside your own cloud or data center, built for healthcare, finance, legal, and government text workloads. Call it from your services and it never sends data to a third party.
$ curl http://localhost:8080/api/filter \
--data "His SSN was 123-45-6789." \
-H "Content-type: text/plain"
His SSN was ***********.Consulting
No in-house engineers? Bring in the team that built the software. We design and deploy PII redaction inside your own cloud, validate it on your data, and hand you a system you own outright. You work directly with the people who wrote the code, not a vendor you renew every year.
We stand up PII redaction in your own cloud, configure and validate it on your data, then hand you a running system you own. No in-house engineering team required.
We design end-to-end PII protection for your data and AI workloads: data flows, redaction layers, audit trails, and the guardrails that keep generative-AI features aligned with HIPAA, GDPR, and CCPA.
Off-the-shelf models miss the identifiers that matter most in your domain. We train specialized PII and PHI detectors on your data, measured against precision and recall you can put in front of an auditor.
