llms.txt file generator

Enter your website address: Pulsar reads your sitemap and your pages, then generates a ready-to-publish llms.txt file so you are better understood and cited by AI models.

We read your sitemap.xml, or otherwise the links on your homepage, then the title and description of each page. No data is retained.

What is an llms.txt file?

The llms.txt is a text file in Markdown format, placed at the root of a website, that presents the structure and key pages of that site to AI models. It is often described as the "robots.txt for artificial intelligence": where robots.txt governs indexing crawlers, llms.txt helps answer engines like ChatGPT, Perplexity, Gemini or Claude find, understand and cite the right content.

In practice, the file starts with the site name and a short description, then lists the key pages grouped by section, each one accompanied by its title and a summary. This machine-readable format saves AI models from having to guess your structure from the HTML alone, and highlights what really matters.

Why set one up?

  • You clearly expose your strategic pages to AI answer engines (generative search, or GEO).
  • You stay in control of the message: the descriptions you write shape the way your brand is presented.
  • You make it easier for your content to be cited in assistant answers, with a link back to your site.
  • It is an open standard, easy to maintain and risk-free for your traditional SEO.

Frequently asked questions

No. It is an open, voluntary standard that is still recent. It is not mandatory, but setting it up takes just a few minutes and helps AI models better understand your site, with no risk whatsoever to your Google or Bing ranking.

At the root of your domain, so that it is accessible at your-website.com/llms.txt, exactly like the robots.txt file.

No, they are complementary. The robots.txt governs indexing crawlers, the sitemap lists all URLs for search engines, and the llms.txt offers a curated, readable map intended for AI models.

The generator gives you a clean and complete starting point. We recommend reviewing the descriptions and refining them: they are what shapes the way your content is presented by AI models.

No. The analysis happens on the fly and nothing is stored. We only read public pages of your site, just as any visitor would.

It relies first on your sitemap.xml, then keeps the most important pages. On large sites, it limits itself to a representative sample to stay fast. You can then complete the file manually.
