Multify documentation

Give your browser superpowers

Multify adds AI to the browser you already use. Look up who emailed you, write a reply where you type, ask about any page, and hand off the clicking. These guides show you how, one feature at a time.

What Multify is

Multify is a browser extension. It puts an AI assistant inside the browser you already use, on the pages you already have open: Gmail, your CRM, a vendor's checkout, a long article, a form you'd rather not fill in by hand. There's no new app to learn and nothing to copy and paste between tabs.

Multify finds things for you, like who a sender is, what a contract says, or the cheapest nonstop flight on the page. It does things for you, like drafting the reply, filling the form, or adding the items to your cart. It also connects to the tools you use, so your calendar, Notion, Slack, HubSpot and your own AI agent are part of the conversation.

You stay in charge the whole way. Multify drafts and fills, and you decide what gets sent or submitted. It always asks before it pays, books, agrees to terms or sends a message for you.

Where it works

Everything in these guides works in desktop Chrome and Firefox, with two exceptions: the Multify new tab is Chrome and Edge only, and only Chrome can move the panel into its built-in side panel. Multify doesn't run on phones as an extension. For your phone there's the mobile app and texting.

Ideas for your job

These pages walk through a normal week with Multify for a few common roles, with prompts you can copy.

  • Sales and lead gen: research prospects from your inbox and LinkedIn, then write the first line.
  • Email: find out who needs a reply, summarize long threads, and draft in your voice.
  • Customer service: answer faster from your help center and order pages.
  • Operations: pull numbers off dashboards, fill the same vendor forms, and turn it into a runbook.

Beyond the browser

Behind the extension is your Multify workspace: chat history, tasks, pages, files, projects and runbooks. Anything you make in the panel lands there, and you can open it on the web at app.multify.co. Multify also works by text message, in Telegram, and in the mobile and desktop apps. Those are under More ways to use Multify in the menu.

What it costs

Installing and using the extension is free. Paid plans and AI credit for premium models are covered on AI models & credit.
