How to use

About this Toolkit

Free aggregator, no signup. All audits run on the listed third-party servers. Looo AI only:

  • Reads the URL you type, runs basic validation (HTTPS, format, domain extraction).
  • URL-encodes it and pre-fills the query parameters on each tool's link so you skip a copy-paste.
  • Direct-links to your public resources like robots.txt and sitemap.xml.

Looo AI stores nothing. All logic runs in your browser; every tool button is a plain link to the third-party site that you can inspect by right-clicking.

Tag legend:

  • Auto fill — your URL is appended as a query parameter the destination tool recognizes.
  • Manual paste — the third-party tool has no pre-fill parameter; paste after opening.
  • Browser extension — the tool ships as a browser extension to install.
  • Login required — official console that requires your own account.

Want all of this consolidated into a single prioritized report? See pricing for Looo AI's unified dashboard.

Turn scattered tool outputs into one actionable list

The Looo AI dashboard (in development) will call these tools in parallel and translate the results into a business-language backlog.
