The ZeroTwo desktop app has a built-in browser. You can open web pages next to your chat, leave comments on parts of a page and send them to ZeroTwo, and let ZeroTwo drive the browser for you. Everything on this page is for the desktop app.
Open the browser
- Choose the Open new tab (+) button in the panel beside your chat, then choose Browser.
- Or press the Open browser tab shortcut, Command+T on a Mac or Ctrl+T on Windows and Linux.
- To show or hide the browser panel, use Toggle browser panel: Shift+Command+B on a Mac or Shift+Ctrl+B on Windows and Linux.
A new tab starts on a page with a few tools and, once you have sites to suggest, a Suggested list. Links you click in ZeroTwo open in the built-in browser by default. To change that, go to Settings > Browser and set Web URL and link open destination (and Local URL open destination for local development sites) to ZeroTwo or Default browser.
Browse and find your way around
The toolbar has Back, Forward and Reload buttons, an Annotate button and the address bar. These shortcuts are the defaults, and you can change them under Settings > Shortcuts.
| Action | Mac | Windows and Linux |
|---|---|---|
| Focus browser address bar | Command+L | Ctrl+L |
| Back | Command+[ | Ctrl+[ |
| Forward | Command+] | Ctrl+] |
| Reload Browser Page | Command+R | Ctrl+R |
| Force Reload Browser Page | Shift+Command+R | Shift+Ctrl+R |
| Find (in the active browser tab) | Command+F | Ctrl+F |
The Browser options menu
Choose the three-dot Browser options button for more:
- Find in page, Print and zoom controls.
- Show device toolbar and Take a screenshot.
- Import cookies and passwords…, which opens Import from your browser so you can bring passwords and cookies from another browser profile on your computer into the built-in browser.
- Passwords and autofill (Password manager and Contact info) and Downloads.
- Clear browsing data, with Clear cookies, Clear cache and Delete download history.
- Browser settings.
- Open in system browser, which opens the current page in your default browser. Use it when a site will not show inside the built-in browser.
Comment on a page with Annotate
- Open the page and choose Annotate.
- Click the part of the page you want to talk about. A box labeled Add a comment... appears next to it.
- Type your comment and press Enter. Repeat for other parts of the page.
- Open Browser options and choose Send. The number beside it is how many comments you made. They are sent to ZeroTwo as a message in the chat the browser is open from.
The same menu has Discard annotations, Copy browser screenshot and Hold to view original. Under Settings > Browser, Annotation screenshots decides whether a screenshot goes with your comments: Always include (the default), Auto or Never. Screenshots help ZeroTwo understand your comments but increase plan usage.
Let ZeroTwo use the browser
ZeroTwo does not control the built-in browser until you allow it. Go to Settings > Browser and turn on the Browser switch, described as "Let ZeroTwo control the built-in browser". Then use Agent permissions to decide what it may do. For Browsing and Downloads you can pick Always allow, Always ask or Never as the default, and add exceptions for specific sites such as example.com or *.example.com. These start out as Always allow.
The same page also has:
- History, which decides whether ZeroTwo can see your built-in browser history. It starts as Always ask.
- Enable site tools, which lets ZeroTwo discover and call tools that websites expose, including WebMCP. It is on by default.
- Developer mode with Enable full CDP access, marked Elevated risk, which lets ZeroTwo run Chrome DevTools tools in a dedicated Chrome profile and may expose sensitive browser data. It is off by default.
The Browser page also manages Show full URL, Browsing data, Browsing history, the Password manager, Extension manager and where downloads are saved. Setting up Google Chrome itself is done in the computer use settings, which the page links to.
