robots.txt / sitemap.xml Generator writes the three small files that sit at the root of a site: a robots.txt with allow and disallow rules, a sitemap.xml built from a list of paths with optional lastmod and priority, and a humans.txt credits file.
It runs in your browser. Nothing you enter is sent anywhere.
It adds a second group that disallows a set of well-known AI training and assistant crawlers. Note that robots.txt is advisory and not all crawlers honour it.
Start each with a slash. You can add up to three more comma-separated values: a lastmod date, a changefreq word, and a priority between 0 and 1.
At the root of your domain, so they are reachable at /robots.txt, /sitemap.xml, and /humans.txt.
No. The files are built in your browser.
