Chrome extension · coming soon
Protect your company's data from AI with RailGuardX.
A Chrome extension that checks every message to ChatGPT, Claude, Gemini, Perplexity, and Copilot — and blocks client names, card numbers, and API keys one keystroke before they leave.
🧩 Installs in Chrome in about 30 seconds — no IT setup, works with your existing AI tools.
Live simulation — this is the extension working in the browser.
Who it's for
Built to protect your company's data
Law firms
Attorney-client privilege doesn't survive a ChatGPT paste. Keep case facts and client names out of AI.
Accounting & CPA firms
Tax data and account numbers are covered by the FTC Safeguards Rule. Enforce it automatically.
Solo pros & small teams
Freelancers, consultants, developers — anyone whose source code, keys, or customer records shouldn't leave the building.
What it does
Three things. That's the product.
- 01
Write a rule in plain English
“Never send client account numbers to AI.” No code, no regex, no consultants.
- 02
The extension checks every message before send
It screens each message in milliseconds using rules — not AI guesswork — so it works every time, even offline. Most checks never touch a server.
- 03
It blocks or redacts the leak
The sensitive part is caught, the rest goes through. Work isn't interrupted — data stays home.
Try it right now
Write a rule. Watch it block.
These four rules are just examples — in RailGuardX you write any policy you want, in your own words. The demo runs entirely in your browser: nothing you type here leaves this page. That's the whole point.
1 · Pick a rule — it can be anything
2 · Now try to leak something
Cards, SSNs, and API keys are caught even with no rule — that layer is always on.
