Edit a website by describing the change

Some changes are a joy to make by hand. Others are death by a thousand clicks: bump the heading, tighten the spacing, soften the corners, deepen the shadow — then do it again across six elements. That's exactly the work you shouldn't be doing manually, and it's what PageBuild's AI agent is for.

Describe the change, get the change

Select what you want to change (or just describe where it is), type the change in plain English, and the agent edits the page. The key word is edits: it applies the change to the live page, exactly as if you'd done it by hand in the inspector.

make the hero heading bigger, tighten its line height,
and give the primary button a soft shadow and more padding

A moment later the heading is larger, the spacing is tighter, and the button has a shadow — on the real page, at the real breakpoints.

It edits. You decide.

The agent isn't a black box that rewrites your site. Every change it makes is a normal edit you can see, keep, tweak further, or undo — just like the ones you make by clicking. If it overshoots, undo it. If it's close, nudge it in the inspector.

• Repetitive restyling: apply the same spacing or type change across many elements at once.
• Fiddly combinations: “bigger, bolder, more padding, softer corners” in a single request.
• Quick exploration: “try a tighter, more editorial layout for this section” and see it instantly.

Why “real edits” beats “here's some CSS”

Plenty of AI tools hand you a block of CSS and wish you luck. Then you're back to copy-pasting, guessing selectors, and checking whether it actually applied. PageBuild closes that loop: the agent's output is the change, expressed as the same structured edits you'd export as clean JSON for a developer. Nothing to paste, nothing to reconcile.

A suggestion is homework. An edit is done.

Write prompts the agent can nail

The agent does best with specific, scoped requests. A few habits help:

1. Name the target. “the pricing cards” beats “the boxes” — or select the element first if it's ambiguous.
2. Bundle related tweaks. Ask for the whole look in one request instead of one property at a time.
3. Describe the goal or the value. “make this feel calmer and more spacious” works; so does “24px padding” — use whichever you actually know.
4. Iterate. Treat it as a conversation: make a pass, see it on the page, refine.

The agent is fastest on the changes you least want to make by hand. Open the editor, load a page, and just tell it what you want.
