Works with Bolt, v0, Replit, Lovable, Cursor and any other AI builder

Find the buttons that don't work and the pages that break on phones.

Your AI builder can't see what happens on your visitors' phones. Paste one line into your site, and every problem real visitors run into comes back as a plain-English summary and a fix prompt you paste straight into your builder.

What it catches

Dead buttons
Buttons and links visitors tap that do nothing at all.
Broken on phones
Pages wider than the screen, so people have to scroll sideways.
Rage taps
The same button tapped again and again because it feels broken.
Forms that don't save
Sign-ups, checkouts and contact forms that fail behind the scenes.
Crashes
Errors that stop part of a page from working.
Missing files
Images, scripts and styles that fail to load.

How it works

  1. Paste one line

    Ask your builder to add our script to your site. We give you the exact words to paste.

  2. Visitors use your site

    The script quietly notices when something goes wrong for them, on any device.

  3. Copy, paste, publish

    Each problem comes with a fix prompt worded for your builder. Paste it, publish, done. You get an email when something new breaks.

What a fix prompt looks like

Paste into BoltCopy fix prompt
On the home page (/), the page is wider than phone screens, so visitors can scroll sideways. The evidence below names the element sticking out the most. Fix the layout so nothing is wider than the screen on mobile. Check fixed widths, long words or links, images, tables and flex rows that don't wrap. Test at 375px wide.
