Questions

The tools, briefly.

Are the tools free?

Yes. Every tool on this page is free and works without an account.

Do I need an account?

No. There are no accounts and no email collection. Open a tool and use it.

What do the tools store?

Nothing about what you enter. The robots.txt generator runs in your browser and sends nothing. The llms.txt checker, the schema generator and the comparison send the domain you type to our server, which reads public files from that domain and returns the result without keeping it. To enforce a rate limit, the server keeps a one-way hash of your IP address with a request counter, which expires within a day. The privacy policy has the detail.

How are they different from the free scan?

The scan reads a site and scores it, so it finds what is missing. The tools act on one finding at a time: check a file, generate the fix, compare two sites. Scan first, then open the tool that fits the finding.

Do the tools say whether AI names my brand?

No. They measure readiness: whether crawlers can reach a site and whether its files and markup give a model something to read. None of them can show whether an assistant names you in an answer.
