The short answer

In the Twinfig extension, switch Data to Mock before you capture. Names, emails, phone numbers, addresses, card numbers and other IDs, handles and avatars are replaced with realistic stand-ins inside your browser before anything reaches the clipboard.

Before you start

  • Google Chrome with the Twinfig extension
  • Access to the app you want to capture
  • The Twinfig plugin open in Figma

Steps

  1. Open the app in Chrome

    Sign in as you normally would. The extension uses your own browser session.

  2. Switch Data to Mock

    Open the Twinfig popup and set Data to Mock.

    The Chrome extension with Data set to Mock and the Notionists avatar style, noting that names, emails, phones, addresses, IDs and avatars are swapped before anything leaves the page. Beside it, the plugin's capture settings with toggles for auto layout, components, design tokens, prototype links, reference screenshot and mock data.

  3. Capture

    Press ⌥⇧P for the full page or ⌥⇧E to pick an element.

  4. Paste into Figma

    Press ⌘V in the Twinfig plugin. The frame arrives with stand-in data.

  5. Review before sharing

    Skim the frame as you would any file that started from a real screen.

Consistent stand-ins

Each person keeps one stand-in across every page and viewport, so a flow still reads like one coherent account.

What stays on your device

Captures built with the extension go to your clipboard, your local history and, if you choose, a .twinfig file. The one network call is to DiceBear when mock avatars are on, and it sends only the mock name.
