Connect Claude & ChatGPT to WebChange Detector

Ask your AI which pages changed after the last check, to take a new set of screenshots, or to put a page under monitoring in WebChange Detector. It can manage URLs and groups, import pages from a sitemap, start baseline and comparison screenshots, and read comparisons with the difference percentage. It can also mark a change as ok, to fix or a false positive.

Free plan, no credit card. Takes about a minute.

Try asking

“Which pages changed visually in the last week?”
The AI lists comparisons from that date range above the change threshold, with the difference percentage for each page.
“Take screenshots of the Shop group after our update and compare them.”
It starts comparison screenshots for the group against the last baseline and checks the batch until the results are ready.
“Import all pages from example.com's sitemap.”
It imports every page listed in the sitemap for that domain as URLs in your account.

What your AI can do

Screenshots and comparisons

Start baseline and comparison screenshots, follow batches and queues, and read comparisons with before and after images and the difference percentage.

URLs and groups

Add pages one by one or from a sitemap, group them, and set desktop, mobile, threshold, custom CSS or JS per page.

Monitoring and alerts

Turn monitoring on for a group, set the interval or hour of day, the change threshold and who gets alert emails.

“Check the Checkout group every 6 hours and email alerts to [email protected].”
It updates the group's monitoring schedule and alert emails. Only the fields you name are changed.
“Mark comparison 5521 as a false positive.”
It sets the status of that comparison to false_positive.
“How many checks do we have left this month?”
It reads your account details, including your plan and remaining checks.

Questions

What can the AI do in WebChange Detector?

The AI can read your account, usage, websites, URLs, groups, batches, queues, screenshots and comparisons. It can add URLs and import them from a sitemap, create and update groups, add or remove URLs in a group, start screenshots, set a comparison's status and delete a URL.

Does the AI see my WebChange Detector credentials?

No. Your WebChange Detector credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start by only reading comparisons. Deleting a URL is permanent, removing URLs from a group stops them being checked there, and screenshots use checks from your plan. These can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own WebChange Detector account.

Do screenshots use my WebChange Detector checks?

Yes. Starting screenshots uses checks from your WebChange Detector plan. The AI can read your account to see how many checks you have left before it starts a run.
