How It Works
Three simple steps to AI-powered legal work without the compliance risk.
Paste your legal question
Type or paste a prompt containing client names, addresses, or case details. The interface shows a badge indicating how many entities were detected.
We replace PII automatically
Before sending to Claude, we swap every detected entity for a consistent pseudonym. "John Doe" becomes "Paul Roberts" and stays that way throughout the conversation.
Get AI answers, toggle real names
Claude responds using pseudonyms. Click "Show Real Data" to see the original client names in the response. Download the mapping table anytime for records.
Built for Legal Professionals
Every feature designed with attorney workflows in mind
Automatic PII Detection & Replacement
Names, addresses, phone numbers, emails, SSNs, and dates of birth are automatically detected and replaced with realistic pseudonyms before your data leaves the browser. Each entity maps to the same pseudonym throughout a conversation.
Entity Mapping Table
A real-time sidebar shows all PII-to-pseudonym mappings with timestamps. Download the complete mapping as a CSV file for compliance documentation and audit trails.
One-Click De-anonymization
Toggle any Claude response between masked and real data. See original client names in AI-generated content with a single click. De-anonymization happens entirely in your browser.
Matter-Based Organization
Organize conversations into legal matters. Entity mappings persist across all conversations within the same matter, ensuring 'John Doe' always becomes 'Paul Roberts' for that case.

Frequently Asked Questions
Is my data really safe?
Yes. The original prompt with PII is never sent to any external service. Only the scrubbed version (with pseudonyms) leaves your browser. The de-anonymization toggle works entirely client-side.
Do I need to provide my own Claude API key?
Yes. You bring your own Anthropic API key. This keeps costs low and gives you full control. Your key stays in your browser and is only used to call Claude directly.
Can I export entity mappings for compliance?
Yes. Pro users can export the complete entity mapping as a CSV file with timestamps, conversation IDs, and matter names. This serves as your audit trail.
What happens to names across conversations?
Within a single matter, the same real name always maps to the same pseudonym. This ensures Claude maintains context and produces coherent output.
What's included in the free tier?
Starter includes 3 matters, 50 messages per month, and basic PII detection (names, emails, phones). Upgrade to Pro for unlimited everything and full entity coverage.
