Agents in your browser: who does what

Two kinds of agent can type and click in your browser. Page Agent is Multify itself, working on the tab you have open. An outside agent is an AI you already use, like Claude or ChatGPT, reaching your browser through Multify. This page shows how they differ, where each one is turned on, and where its settings live: in the extension, in the web app, and in Stash.

Two kinds of agent

Page Agent

Multify itself, working where you are

You

Ask in the Multify panel on the tab

Fill in this contact form with my details.

Multify

Plans the steps and asks when it must

Reads the page, decides what to do, and checks each step before it runs.

Your browser

Types and clicks on this tab

The page shows Multify is using this page · Stop. Another website opens in a tab behind yours if you choose.

Outside agents

An AI you already use, reaching your browser through Multify

Your AI app

Claude, ChatGPT, Grok or Cursor asks over Multify MCP

Open amazon.com and search for sugar free Red Bull.

Multify

Sends it to a browser you turned on

Checks the site is allowed there. When it isn't, a card waits for your answer.

Your browser

Works in a tab behind yours

You keep your tab in front. The same pill and Stop sit on the agent's tab.

Page Agent is Multify working on the tab you have open. An outside agent is an AI you already use, reaching your browser through Multify. Both use the same page skills and the same rules about asking first.

They share the part that touches the page: the same reader, the same way of typing and clicking, the same pill with Stop, and the same list of steps that always ask you first. What differs is who plans the work and where the request comes from.

	Page Agent	Outside agents
Who plans the steps	Multify, in the panel on your tab	Your AI app: Claude, ChatGPT, Grok, Cursor or another MCP client
How you start	Type what you want in the panel on the page	Ask your AI app. It reaches your browser over Multify MCP
Where it works	The tab the panel is on, or a tab it opens behind it	A tab behind the one you're using
Turning it on	Nothing to turn on. Allow the site when it asks	Off until you turn it on for a browser, or for all your browsers at once
The first question on a site	Allow once, Auto-approve this chat, Always approve this website	Allow once, Always allow outside agents, Not now
Always asks first	Paying, booking, agreeing to terms, sending a message, typing a password, deleting something, uploading a file	The same list
Where the settings are	The extension only: Settings → Page Agent	The extension: Settings → Outside agents. The web app and Stash: the account default and the browser list
Full guide	Page Agent	Let your agent use your browser

Which one to use

Use Page Agent when you're already on the page and want the job done there: fill this form, search this site, add these items to the cart. You see it work and you answer its questions in the same panel.

Use an outside agent when the work starts somewhere else. You're planning in Claude or ChatGPT, or a Cursor task needs a page that only your signed-in browser can reach, like a supplier portal or your CRM. Your AI app does the planning and your browser does the clicking, while you carry on in the tab in front.

Both at once Turning on outside agents doesn't change Page Agent. A browser can answer your AI app in a background tab while you ask Page Agent for something on the tab in front. Each works on one site at a time.

The web app and Stash show the same account settings. Change them in either place.

The extension card is about this browser: whether it answers outside agents, what it's called, and how much it asks. The web app and Stash are about your account: a default for every browser, and a list where you can turn each one on or off from anywhere.

In the extension

Open the Multify panel, then ☰ → Settings. Two cards matter here, and both are drawn card by card on The Multify panel.

Page Agent: your saved form details, the websites you always approve, custom instructions, and two switches that are off by default (skip the extra confirm for sensitive steps, share usage anonymously). These exist only in the extension. The web app and Stash don't show them.
Outside agents: everything about this one browser. Let outside agents drive this browser is the switch that matters. Browser name is how your AI app picks this browser when you have more than one. The rest decides how much it asks: Disable approval permissions, Let outside agents use my saved details, Close tabs agents opened, and the list of websites you've chosen to always allow.

Under the browser name, the card says what outside agents see about this machine (for example, "Chrome 141 on macOS 14.6 (Apple Silicon), extension 0.66.2") and where its on or off came from: this browser, or your account default.

In the web app and Stash

Sign in at app.multify.co and open Settings → Outside agents, or in Stash open Settings → Outside agents. Both show the same card:

Turn on for all my browsers. The account default. Every browser you sign in to that hasn't been set individually follows it, including browsers you add later. Turning it on asks you to confirm first, because it makes those browsers driveable by any agent you've connected over Multify MCP. They still ask before a new site and before paying, booking, agreeing, sending or deleting, unless you also turned off approval permissions on that browser.
Your browsers. Every browser signed in with the extension shows up here once it checks in, even ones that are off. Each row has the browser's name, what outside agents see about the machine, when it was last seen, and a line saying whether it's on or off and why. Its switch turns that one browser on or off from here. Follow account default puts a browser you set individually back on the default.
Disable approval permissions, per browser. Under each browser's name. Turning it on from here shows the same disclaimer as the extension, then asks for a code we email you, because you may not be at that machine. Turning it off needs neither. There's no version for all browsers at once. See Turn off approvals from the web.

A browser that's off can't be driven and doesn't show up for your AI app at all. The card in the extension, the web app and Stash is also where you can see which of your browsers agents can reach right now.

How a browser decides whether it's on

This browser's own setting	Account default off	Account default on
Follows the account defaultEvery browser starts here. Also what Follow account default sets.	OffOff — following your account default.	OnOn — following your account default. The extension shows a one-time note with the date it turned on.
Turned on in the extensionOr on from the web app or Stash list.	OnOn — turned on for this browser.	OnOn — turned on for this browser.
Turned off in the extensionThe extension warns first when the account default is on.	OffOff for this browser.	OffOff on that browser. Turn it on in the Multify extension on that machine. The web app can't turn it back on.

A browser follows your account default until you set it yourself. Turning a browser off in the extension sticks: the web app and Stash show it as off and can't switch it back on, so a machine you've opted out stays out until someone at that machine changes it.

Three things are worth knowing about this:

The latest change wins. Set a browser on from the web app and it's on, whatever the default says. Set it off from the web app and it's off. Follow account default clears that and the default takes over again.
Off in the extension is sticky. If you turn a browser off on its own machine while the account default is on, the extension warns you first, and afterwards the web app and Stash can only show it as off. That's deliberate: a machine someone opted out shouldn't be opted back in from somewhere else.
You're told when the default turns a browser on. The next time you open Settings in that browser, the Outside agents card notes that outside agents were turned on by your account default, with the date. Dismiss it with Got it.

What both always ask

Whichever agent is working, these wait for your yes on any site, even one you always allow: paying, booking, agreeing to terms or a privacy policy, sending a message, typing a password, deleting something or changing account security, and uploading one of your files. Adding something to a cart, or taking it out again, isn't one of them. Before a payment or booking, the card shows the order first. For Page Agent, Skip the extra confirm for sensitive steps lets the first five go ahead on approved sites. For outside agents, Disable approval permissions moves those questions into your AI app's own chat instead of the browser. Both are off by default and both show a disclaimer before you turn them on.

The approval cards themselves, and what each choice covers, are on Page Agent and Let your agent use your browser.
