Build your first page

This guide walks you through building or editing a page with Impossible.

​
Open the builder

  1. Go to Impossible in the WordPress admin menu.
  2. You’ll see the three-panel layout:
    • Left: Site Explorer — your pages and posts
    • Center: Preview — live preview of the selected page
    • Right: Chat — where you type prompts

​
Select a page

In the Site Explorer, click a page (e.g. Home) to select it. The preview loads that page. The agent uses the selected page as context for your prompts.

​
Type a prompt

In the Chat panel, type what you want. Examples: Press Enter to send. The agent reads your site, makes changes, and the preview refreshes when done.
Be specific. “Add a hero with headline X and CTA Y” works better than “add a hero.” See Prompting basics for more tips.

​
Preview and iterate

  • The center panel shows your changes in real time.
  • Use the device toggles (desktop, tablet, mobile) to check responsive layout.
  • Use the zoom controls to adjust the preview size.
  • Type another prompt to refine or add more content.

​
Publish or discard

All edits are staged until you publish. Your live site does not change until you click Publish.
1

Review changes

Check the preview and the Change log (below Site Explorer) to see what was modified.
2

Publish

When ready, click Publish in the bottom bar. This publishes all staged changes (pages, CSS, theme files) to the live site.
3

Or discard

To undo everything without publishing, click Discard. All staged changes are removed.

​
Undo and redo

  • Use Undo / Redo in the chat panel or bottom bar.
  • Keyboard shortcuts: Ctrl+Z (Windows/Linux) or Cmd+Z (macOS) for Undo; Ctrl+Shift+Z or Cmd+Shift+Z for Redo.
  • The Change log lists recent changes; use Revert on an entry to undo back to that point.
Undo and Redo only affect the staged state. Once you publish, those changes are live and cannot be undone through Impossible.
