Otto's browser

Otto has its own browser, so it can use websites the way you would.

The browser runs on Otto's computer, separate from your own browser. It doesn't share your tabs, cookies or saved passwords.

What Otto can do

Open pages, click, type, fill forms and pick options.
Read the page and look at screenshots, including canvas and visual controls.
Run JavaScript on the page.
Download files and upload files from its workspace.
Sign in with logins you saved in Vault, without seeing the password.

Take over the browser

When Otto needs you on a page, it asks in chat with an Open browser link.

Open Otto on the desktop or the web. The live page appears under Otto's message.
Click, type and scroll on the page. Use Back and Reload if you need them, or Enlarge browser for a bigger view.
When you're finished, select Done. Otto looks at the page again and carries on.

Otto doesn't watch or act while you have the browser. If you started on Telegram or WhatsApp, open Otto to take over, because chat apps can't show the page.

CAPTCHAs and human checks

Otto tries a challenge first. It reads the instructions, looks at fresh screenshots and makes up to three informed attempts. It stops at a block, rate limit or lockout. Then it hands the browser to you and says what it tried.

Passkeys. Otto doesn't supply a passkey authenticator. Use another sign-in method, such as a password saved in Vault.
Approval on your phone. When a site asks you to approve on another device, Otto tells you what the page says. Then it checks the page every 15 seconds, up to eight times, and continues once the page confirms. It stops if the request is denied or expires, and asks you if the result stays unclear.

One holder at a time

The browser has one holder: the conversation, a background task or you. Anyone else waits in line.

  [*] --> Free
  Free --> conv: chat needs it
  Free --> bg: a run needs it
  conv --> you: Open browser
  you --> conv: Done
  conv --> Free: task ends
  bg --> Free: run ends

While Otto waits for you, the conversation keeps the browser, so background work can't take it from under you. If you don't use it for 30 minutes, Otto lets it go.

Saved routines

When Otto repeats the same steps on a website, it can save them as a routine and reuse it next time. A routine stops if a step fails, the browser leaves the website or the page doesn't match a saved check, so Otto can look and fix it.

Routines never store passwords or codes. They're kept in /workspace/.otto/browser-flows and stay even if the chat is cleared. To make one, ask Otto to save what it just did as a routine.

Downloads

Otto downloads files into its workspace, up to 12 MB each. In a conversation it also sends them to you in chat. Downloads from background work stay private until Otto shares them.

Vault and saved loginsSave a login once. Otto signs in without seeing it.

Saved browser sessionsReuse a signed-in browser on websites you allow.

After you sign in by hand, Otto may offer Save login in Vault for next time.
