Tess in Chrome is the Tess Browser Use extension. With it connected, chat acts in the browser where your session is already open. A request becomes action on the page: open, read, click, type, scroll, download, and upload. You keep the login you already have. Tess uses that open session on the client portal, the internal admin, the ticket queue, or the web spreadsheet. A site with no connector in Tess still fits this flow. You watch it in Chrome. The extension icon stays Online while it listens to chat, and the activity list shows each step. Disconnect stops it immediately.
The extension is in beta. Leave the browser open, with the extension online, on the same workspace as the chat.

​
Which browsers

Install it from the Chrome Web Store. It runs in Chrome and in other Chromium browsers that accept that store, such as Brave and Edge. Firefox and Safari are out.

​
Who configures it

​
What you can hand off

The session you already have

Tess looks up, fills, and replies inside the site you already signed in to. The session stays in your browser. Chat receives what the page shows and what you asked Tess to do.

A site with no connector

An old admin, a client portal, or an internal tool becomes something you can ask for in chat, the same way you would ask about a public page.

Files in both directions

A PDF or CSV on the page lands in the conversation. A file already in the conversation goes into an upload field on the page.

A tab you can see

The work happens in a tab group for that conversation. Your other tabs stay outside that group. On a login wall or a captcha, Tess stops and tells you what is blocking it.

​
Install and connect

1

Install Tess Browser Use

Open the Chrome Web Store and add the extension.
2

Sign in with your Tess account

Click the extension icon and choose Sign in with Tess. Tess opens its usual login (email, Google, or SSO). After you sign in, you return to the extension. There is no token to copy.
3

Choose the workspace

Tess only acts in the workspace you select. Optionally name this browser, for example “Work laptop”, so you can recognize it in your account.
4

Save and connect

Choose Save and connect. The status becomes Connected — Online. The extension then listens for commands from that workspace.
If the workspace has no access to the extension, the setup screen says so. Ask a workspace admin to enable it.

​
Use it in chat

1

Open a chat in the same workspace

The chat workspace and the extension workspace have to match. If the extension is on another workspace, chat asks you to switch it and connect again.
2

Turn on Browser Extension

In the composer, open +, go to connectors, and turn on Browser Extension. The item shows a Beta badge.
3

Name the site and the result

Include the address, what to look at, and what to bring back. Example: “Open https://admin.example.com/orders, filter this week’s late orders, and return a table with number, customer, and date.”
4

Leave the browser open

Tess opens or reuses a tab, looks at the page, and takes one step at a time. The extension popup lists the activity.
On the first run, ask for a reading. On the next message, ask for the action. For example: “Fill the reimbursement form with these fields and stop on the review screen.”
If this agent does not allow tools, the item stays disabled and the composer says the agent setup blocked it.

​
Prompts worth a first session

  • “Open this status page and tell me which services are degraded right now.”
  • “In the admin, download this month’s usage CSV and point out accounts that dropped more than 20%.”
  • “Reply to ticket 441 with this text and send it.”
  • “Upload this conversation file into the attachment field and show me the screen after the upload.”

​
What Tess does on the page

​
Which sites it can open

Anyone who can edit workspace settings does this in the Settings modal, not in the extension.
1

Open Settings

Click your name in the corner of the screen and choose Settings.
2

Open Workspace

In the sidebar, under the Workspace group, click Workspace.
3

Scroll to the extension card

The Browser extension domain policy card is at the bottom of that screen, after Profile Settings and Social profiles. It holds Allowed domains and Blocked domains. Manage domains one by one opens the same lists, one domain at a time.
People who cannot edit workspace settings see those fields disabled.
  • Allowed domains. When this list has any domain, the extension only acts on those domains and their subdomains. example.com covers example.com and www.example.com. It does not cover my-example.com.
  • Blocked domains. These sites stay out. A domain on both lists stays blocked.
  • The platform-wide policy overrides the workspace list.
Some destinations are blocked from the start: local pages, Google and Microsoft account login screens, and payment surfaces such as PayPal and Stripe.

​
When something stalls

  • Session expired. Open the extension settings and sign in with Tess again.
  • Extension out of date. The popup asks for an update. Update it from the Chrome Web Store and connect again.
  • Saved, still offline. In settings, choose Save and reconnect.
  • Chat does not touch the browser. Check three things: status Online, the same workspace in the popup and in the chat, and Browser Extension turned on in the composer.
  • Login or captcha on the page. Tess stops and describes the block. Resolve it in the tab and ask Tess to continue.
  • Switch accounts. In the extension settings, choose Switch account. To stop immediately, open the popup and choose Disconnect.
