Claude is famous for its massive context window and document analysis. PrivacyScrubber lets you parse PDFs and DOCX files locally, remove all PII, and then safely upload the sanitized text to Claude.
Anthropic processes data in the cloud. By scrubbing the data on your client device first, you eliminate transit risks and comply with strict corporate data residency requirements.
If you use Claude for debugging, PrivacyScrubber can sanitize your server logs and SQL dumps (removing IP addresses, auth tokens, and emails) before you ask Claude for help.
