About Dex Extension

Install the Dex Chrome extension to add contacts, write notes and set reminders from LinkedIn, Gmail, Instagram, Facebook, X and more without leaving the page.

The Dex Extension puts Dex on the sites where you meet people. Open someone's profile or an email thread, click the Dex icon, and you can add them, write a note or set a reminder without switching tabs.

Install the extension

Add it to Chrome

Open the Dex listing in the Chrome Web Store and click Add to Chrome. It's listed as Dex - Personal CRM & Contacts.

Sign in

Sign in with your Dex account when the extension asks.

Pin it (optional)

Click the puzzle-piece icon in Chrome's toolbar and pin Dex so it stays in view.

The Dex Extension runs in Google Chrome. The Dex desktop app can't run browser extensions, so use Chrome for anything that needs the extension.

Use the extension on a profile

Open a contact's profile on a supported site and click the Dex icon.

Open in Dex button from the Dex Extension on an Instagram profile

If the person isn't in Dex yet, the extension adds them. If they're already in Dex, it opens their contact instead.

From the extension you can:

  • Run Enhance contact to fill in their details
  • Set a Keep in Touch frequency
  • Add a note, event or reminder
  • Add them to a group
  • Star the contact
  • Edit their information on the Details tab
  • Archive or delete the contact
  • Open the full contact in Dex

Supported sites

Each site has its own guide covering where the Dex icon shows up and what it adds:

What needs the extension, and what doesn't

Some syncs connect through the extension. Others don't use it at all.

FeatureNeeds the extension?
Instagram SyncYes, to connect. Connect once from Chrome, and the sync then runs on Dex's servers.
Facebook importYes, to connect. Connect once from Chrome, and the sync then runs on Dex's servers.
LinkedIn SyncNo. Connect it from the Dex mobile app or the Dex desktop app.

Manage site access

You choose which sites the Dex Extension can read. To jump straight to its settings, paste this into Chrome's address bar:

chrome://extensions/?id=amlpnkfionniifnajgcalfndolieichk

Or go there step by step:

Open Chrome's Extension Manager

Select the Dex Extension

Turn sites on or off under Site access

If you block a site here, the Dex icon won't appear on it.

Update the extension

Chrome updates extensions on its own. If you know a fix has gone out but you're not seeing it, you can force an update:

  1. Go to chrome://extensions
  2. Turn on Developer mode (top-right corner)
  3. Click Update
  4. Refresh any tabs where you use Dex
Update checks every extension you have installed, not just Dex.

Fix the extension when it isn't working

If the Dex icon is missing or the extension isn't responding, work through these in order:

  1. Hard-refresh the page: Cmd + Shift + R on Mac, Ctrl + Shift + R on Windows
  2. Make sure the site is allowed under site access
  3. Turn the Dex Extension off and back on in chrome://extensions
  4. Update the extension
  5. Restart Chrome
  6. Remove the extension and reinstall it from the Chrome Web Store
Chrome sometimes disables an extension after an update that asks for new permissions. If Dex is switched off in chrome://extensions, turn it back on and accept the permissions.

Mail Merge

Mail Merge lets you send a personalized email to up to 200 contacts in one workflow.

Instagram Integration

After successfully installing the Chrome extension, you'll notice a Dex icon next to Instagram profiles when browsing Instagram on the web. Clicking this button will either add the profile to Dex or link it to an existing Instagram contact.
