Free tools
Write it, then check it, with the rules we ship.
Three free tools for the files and markup that AI assistants and search engines read first. They're an llms.txt generator and checker, a robots.txt generator that names each AI crawler, and a schema markup generator. Each runs Heddle's own code in your browser, the same rules its gates hold every page to, with no sign-up and nothing tracked.
llms.txt generator
Generate an llms.txt from your sitemap or by hand, or check a live one against the llmstxt.org format. It runs in your browser, with no sign-up.
Runs in your browserRobots.txt generator
Generate a robots.txt that names each AI crawler, or check a live one to see which bots it blocks and the line that decides it. Free, in your browser.
Runs in your browserSchema markup generator
Generate JSON-LD schema markup for an organization, article, FAQ, event, product or breadcrumbs, checked against what Google requires. Free, in your browser.

Why are they free?
They're the rules Heddle already runs on every build, given a form. If they're useful, you'll know what the agents check before you talk to us, and that's the point.
What happens to what I type?
Nothing leaves your browser, except when you ask a tool to read a live file. Then our server fetches that one file, robots.txt, llms.txt or sitemap.xml, from the site you name and hands it back. It stores nothing, and the pages carry no analytics.
Will these get me into AI answers?
They remove the reasons an assistant can't read or cite you, like a crawler blocked by accident, no map of the site, or markup missing a field. Being cited still depends on the pages saying something worth citing.
