Privacy, built into how you use AI.
Kirtonic is a free browser extension that checks what you share with ChatGPT, Claude, Gemini and Copilot, and holds back passwords, personal details and card numbers before they ever leave your browser.
Checked before it's sent. Never after.
You type as normal
Use ChatGPT, Claude, Gemini or Copilot exactly as you do today. Kirtonic sits quietly in the background.
Kirtonic checks it
As you write, it scans for passwords, personal data and card details, plus anything on your own block list, right inside the browser.
Risky bits are held back
If something sensitive is about to be shared, Kirtonic flags it before it leaves your device. Your full messages are never stored or shown.
Everything in one calm dashboard.
What we protect
Toggle protection for passwords & keys, personal details (emails, phone numbers, IDs), and card & bank info. On by default.
Your own rules
Add anything else in plain words, an employer name, a project codename. Kirtonic matches close variations and common typos.
Sensitivity level
Choose Light, Balanced or Maximum, how carefully Kirtonic checks, so you get the right balance of protection and flow.
Recent activity
See what's been checked and what was held back, across every AI tool. Your full messages are never displayed.
Privacy first
Checks happen in your browser. Kirtonic never sees your full messages, only what's needed to keep you safe.
