AI is powerful. The question is
what you're trading for it.

You feel it every time. The brief hesitation before hitting send. The quiet question: should I really be pasting this?

Your data becomes their data

You paste a contract into ChatGPT. Somewhere in the terms you accepted, that content can now be used to improve their models. Your client's name, their deal terms, their contact details — all part of the training set.

Documents carry more than text

A PDF contains author names, edit history, GPS coordinates, deleted paragraphs. You think you're sharing a clean document. You're actually sharing its entire lifecycle.

The damage is always personal

A leaked client name isn't an "incident." It's a phone call you don't want to make. A compliance investigation. A relationship that took years to build, broken by a single paste.

Three steps. Everything stays local.

From raw document to safe AI interaction, processed entirely on your Mac.

1

Drop in your document

Import a PDF or Word file. RedMatiq strips all hidden metadata and scans for sensitive data — names, addresses, phone numbers, financial details — using an on-device AI model. Nothing leaves your machine.

2

Review what's detected

Sensitive items are flagged and pseudonymized automatically. You keep full control: toggle individual items, add manual redactions, adjust what matters. Your judgment, amplified.

3

Work with AI — safely

Chat with your documents using the built-in AI, export clean files for Claude or ChatGPT, or connect via MCP server. The AI gets a structurally perfect surrogate. Your original data never moves.
