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 — all offline. 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 entirely on your machine — no document content ever leaves your computer.

  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. The real names never leave your machine.

  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.

PDF Tools

Beyond redaction, Lex Redactus has built-in PDF tools: split a filing into separate exhibits, merge affidavits and exhibits into one paginated packet, and stamp black redaction boxes onto a page — all offline, never uploaded.
