Product summary
Review the store description, core capabilities, and common use cases.
JackalShield anonymizes sensitive documents before you share them with AI assistants like ChatGPT, Claude, or Gemini. It automatically detects and replaces personally identifiable information (PII) — so you can use AI safely without exposing confidential data.
How it works
Drag and drop a document onto the ChatGPT or Claude chat window — or use the extension popup.
JackalShield detects sensitive data using regex patterns and a local AI model (NER).
All detected PII is replaced with realistic-looking placeholder data.
The anonymized text is pasted directly into the chat.
