Personal email blocked
Sign-ins with an address outside your approved domains, such as Gmail or Outlook.com, are stopped before they're sent.
Free Chrome extension for IT teams
Keep staff on work accounts in AI tools.
AI Account Guard stops personal sign-ins to ChatGPT, Claude, Gemini and other AI services in Chrome, so work data stays in accounts your organization controls.
Free and open source. No accounts, no servers, no tracking.
Personal AI accounts are a quiet data leak.
When someone pastes a contract, a client list or source code into a personal ChatGPT or Claude account, that data leaves your organization's control. You can't see it, keep it or delete it, and it's covered by terms your organization never agreed to.
Most people don't mean any harm. They're already signed in at home, or a personal account was quicker to set up. AI Account Guard catches that moment in the browser and points them to your work account instead.
It doesn't stop people using AI. It makes sure they use it with an account you manage, such as a ChatGPT Business or Claude Team workspace, or your Microsoft 365 or Google Workspace sign-in.
How it works
AI Account Guard checks sign-ins as they happen, inside Chrome.
Personal sign-in buttons blocked
"Continue with Apple", GitHub, X and phone sign-ins are stopped on AI services, since they can only lead to personal accounts.
Microsoft and Google, your org only
"Sign in with Microsoft" or "with Google" can stay on, limited to your organization's accounts by Microsoft's and Google's own tenant restrictions.
Block services entirely
Choose per service: work accounts only, or blocked. Meta AI, which only offers personal accounts, is blocked by default.
A clear message, not a dead end
Staff see your organization's name, your help-desk message and a button to your company sign-in page.
Ten AI services covered
ChatGPT, Claude, Gemini (with AI Studio and NotebookLM), Microsoft Copilot, Perplexity, DeepSeek, Grok, Mistral Le Chat, Poe and Meta AI.
What your staff see
Every message names your organization and shows them the right way in.
Deploy it in an afternoon
Built for Microsoft Intune, Jamf Pro and the Google Admin console. Staff can't remove it or change its settings.
-
Make your settings file
The setup page looks up your domain, asks a few questions and builds the file for your tool. It takes about five minutes.
-
Push it to your computers
Upload it to Jamf, Intune or the Google Admin console. Chrome installs the extension and applies your settings.
-
Check one machine
Confirm the settings arrived in
chrome://policyand try a personal address on ChatGPT. Then roll it out.
Private by design
A security tool that reads sign-in forms should earn that trust. AI Account Guard does its work entirely inside the browser.
- No accounts, no servers, no analytics and no tracking.
- Email addresses are checked in the browser and never stored or sent anywhere.
- It doesn't report anything back to StratIT or to your organization.
- Free and open source under the MIT license. Read the code on GitHub.
- Read the privacy policy.
Good to know
What AI Account Guard does and doesn't cover, so you can plan around it.
- Chrome only. Block other browsers and desktop AI apps with your device management tools for full coverage.
- Managed Chrome for locked settings. Without Intune, Jamf or Google Admin, staff can remove the extension.
- Signing in is what's checked. Services that can be used without signing in still can be. Block them per service if that matters.
- A work email on a free plan is still a free plan. Pair this with a business AI subscription your organization manages.
- Passkey sign-ins don't show an email address, so they can't be checked.
