Watch how Lex Redactus works

A short narrated walkthrough of the full workflow: detect PII in a legal memo, redact it into reversible tokens, use any AI (Gemini, Claude, ChatGPT, Grok) safely, and decode the reply back to the real names. PII never leaves your computer unless you allow it. The clip uses a fictional document; no real client data.

Narrated screen recording of the actual app. Captions included.

The workflow, step by step

1. 1

   Everything runs locally

   Lex Redactus works on your computer. PII never leaves your computer unless you allow it.

2. 2

   Create a matter

   Each case gets its own matter, keeping documents, the entity map, and audit history isolated.

3. 3

   Add a document

   Upload a PDF, DOCX, or scanned image, or paste text directly.

4. 4

   Detect PII locally

   One click runs local detection over names, organizations, SSNs, phone numbers, addresses, and case numbers.

5. 5

   Review the findings

   Accept, reject, or add detections by category. Attorney judgment stays in the loop.

6. 6

   Redact into tokens

   Each real value becomes a reversible token like [[PERSON:01]], recorded in the entity map.

7. 7

   Use any AI safely

   Finalize, then paste the tokenized text into Gemini, Claude, ChatGPT, or Grok. PII never leaves your computer unless you allow it. Paste-to-AI is that exception.

8. 8

   Decode the AI's reply

   Paste the AI's response (still tokenized) into the decoder, and the tokens turn back into the real names, locally.
