Validate any site's llms.txt against the llmstxt.org spec (title, summary, sections, link lists), check that its links resolve, and detect llms-full.txt. Free, no sign up.

SEO tools at mytoolstudio share three rules. They run in the browser whenever possible. They never lock features behind sign up. And they keep your data on your device unless server work is the only way.
Small habits that compound across a workweek.

Stop reading. Start using.
That is everything worth saying. Open the tool and try it on something real. You will know within a minute whether it belongs in your kit.
