Install the Chrome Extension
Crosscheck runs as a Chrome browser extension. Follow these steps to install it, pin it to your toolbar, and sign in to your account.
Installation steps
Open the Chrome Web Store listing
Visit the Crosscheck extension page on the Chrome Web Store:
chromewebstore.google.com/detail/Crosscheck/acnahejlmejjbbloeodkkpapmbnieljf
Click "Add to Chrome"
Click the Add to Chrome button on the store listing. A confirmation dialog will appear showing the permissions Crosscheck needs. Click Add extension to confirm.
Pin the extension to your toolbar
After installation, Crosscheck may be hidden in the extensions menu. To keep it visible:
- Click the puzzle piece icon in the Chrome toolbar to open the extensions menu.
- Find Crosscheck in the list.
- Click the pin icon next to it so it stays visible in your toolbar at all times.
Sign in or create an account
Click the Crosscheck icon in your toolbar to open the extension popup. From here you can either Sign Up or Login:
- Sign Up — You will be redirected to app.crosscheck.cloud where you can sign up with Google or enter your email to create a new account.
- Login — You will be redirected to the same page, where you can enter your registered email or continue with Google. After authenticating, you are taken straight to your dashboard.
Troubleshooting
The extension icon does not appear
Make sure you have pinned the extension (Step 3 above). If you still do not see it, visit chrome://extensions and verify that Crosscheck is listed and enabled.
Extension installed but checks fail
Some pages restrict extension access, including Chrome internal pages (chrome://), the Chrome Web Store, and other extension popups. Try capturing on a regular web page instead. See the Extension Issues guide for more help.
