Interactive intelligence tool

Run the check, then ship the workflow

Use the browser tool for a fast answer, then move the same logic into scripts, monitoring, or product flows when it becomes repeatable.

1
Start with the live form

Enter a domain, URL, IP, email, or record and get a focused result without setup.

2
Review decision-ready signals

Outputs highlight statuses, risks, records, and next actions instead of raw provider noise.

3
Automate the workflow that works

Use the request and response examples to turn a one-off check into an API call or recipe.

Frequently asked questions

What similarity is a problem?

Pairs at 0.8 or higher are near duplicates and may compete in search.

How do I fix duplicate pages?

Merge them, rewrite one, or point the copies to the main page with a canonical tag.

Can I compare pages from different sites?

Yes. Any public pages can be compared.
