This guide shows you how to install the PromptDuty browser extension locally using Developer Mode. This is useful while waiting for Chrome Web Store approval or for testing purposes.
Note: Once the extension is approved on the Chrome Web Store, we recommend switching to the store version for automatic updates. We'll notify you when this happens.
Prerequisites
Before you begin, make sure you have:
- Google Chrome or Microsoft Edge browser installed
- The PromptDuty extension ZIP file (provided by your administrator)
- A location to extract the files (e.g., your Documents folder)
Installation Steps for Chrome
1Extract the Extension Files
Unzip the PromptDuty extension file to a permanent location on your computer. We recommend creating a folder like Documents/PromptDuty.
- Right-click the ZIP file and select "Extract All" (Windows) or double-click to unzip (Mac)
- Choose a location you won't accidentally delete
2Open Chrome Extensions Page
Open Chrome and navigate to the extensions page:
- Type
chrome://extensionsin the address bar and press Enter - Or: Click the three-dot menu β More tools β Extensions
3Enable Developer Mode
In the top-right corner of the Extensions page, toggle on Developer mode. You'll see additional options appear.
4Load the Extension
Click the "Load unpacked" button that appeared after enabling Developer mode.
- Navigate to the folder where you extracted the extension files
- Select the folder containing the
manifest.jsonfile - Click "Select Folder" (Windows) or "Open" (Mac)
5Verify Installation
The PromptDuty extension should now appear in your extensions list with its shield icon. You should also see it in your browser toolbar.
Installation Steps for Microsoft Edge
The process is nearly identical for Microsoft Edge:
1Open Edge Extensions Page
Navigate to edge://extensions in the address bar.
2Enable Developer Mode
Toggle on Developer mode in the bottom-left corner of the page.
3Load the Extension
Click "Load unpacked" and select the extracted extension folder.
Configuration
After installation, you'll need to configure the extension:
- Click the PromptDuty icon in your browser toolbar
- Enter your organization's license key (provided by your administrator)
- The extension will connect to your organization's settings and begin protecting your AI prompts
Troubleshooting
Extension not appearing in toolbar
Click the puzzle piece icon in Chrome's toolbar and pin PromptDuty to make it always visible.
"Errors" badge on the extension
This is normal for locally-loaded extensions and doesn't affect functionality. Chrome shows this warning for any extension not installed from the store.
Extension disabled after browser restart
Chrome may occasionally disable unpacked extensions. Simply return to chrome://extensions and toggle the extension back on.
Important: Do not move or delete the extension folder after installation. Chrome references the original folder location. If you need to move it, remove the extension first, move the folder, then load it again.
For IT Administrators
If you need to deploy PromptDuty to multiple users in your organization, we recommend:
- Microsoft Intune: See our Intune deployment guide
- Google Workspace: See our Google Workspace deployment guide
These methods allow centralized deployment and policy management without requiring users to manually install the extension.
