CONFIDENTIAL — Engagement letter excerpt

Northbridge Holdings LLC and Jordan Hale entered into this Agreement on January 15, 2024.
Case No. CV-2024-00123 concerns the property at 1200 Market Street, San Francisco, CA 94102.

Please brief ChatGPT only after redaction.

Lawyers already paste contracts into ChatGPT. The risk is the paste.

SafeToAI sits in front of that habit: redact first, then analyze. It is not another AI lawyer — it is the privacy step your AI workflow is missing.

Common path

Matter → paste / upload → ChatGPT

Client names, IDs, and deal terms leave your machine before you have reviewed what the model will see.

SafeToAI path

Matter → redact in browser → Markdown → ChatGPT

Parsing and detection stay local. You export only the redacted text you choose to share.

From highlighted matter text through a local filter to AI-ready tokens

From matter file to AI brief in four steps

Same core workflow as dedicated offline redaction tools — delivered as a shareable web workspace for English-speaking legal teams.

  1. 01

    Open a matter file locally

    Drop DOCX, text-based PDF, TXT, or Markdown. Parsing runs in your browser with Mammoth / PDF.js — the file is not sent to SafeToAI.

  2. 02

    Review every detection

    Toggle, remove, or add spans. You stay responsible for the final redaction before anything leaves your machine.

  3. 03

    Export Markdown for AI

    Download clean Markdown with stable tokens like [PERSON_01] so ChatGPT or Claude can reason about the deal without seeing real identities.

  4. 04

    Optional local restore

    Keep a mapping.json on disk. When the model returns analysis, restore originals locally — still without uploading the matter.
