Generate a structured llms.txt file that tells ChatGPT, Perplexity, Claude, and other AI crawlers what your site contains and where to find your best content. Add sections manually, import from a sitemap, auto-fetch page titles, and download a ready-to-deploy file.
llms.txt is a proposed standard (similar to robots.txt) that helps AI systems understand a website's structure. It sits at yourdomain.com/llms.txt and provides a structured Markdown summary of your pages, helping AI answer engines like ChatGPT, Perplexity, and Claude index and cite your content.
ChatGPT, Perplexity, Claude, and other AI crawlers that follow the llms.txt convention will use the file to better understand your site. Adoption is growing quickly as AI-generated search becomes a primary discovery channel.
robots.txt tells crawlers which pages not to visit. llms.txt is the opposite — it proactively tells AI systems what your site is about and where your most important content lives, improving your chance of being cited in AI-generated answers.
Yes. Enter your sitemap URL (e.g. yourdomain.com/sitemap.xml) and click Import. The tool fetches your sitemap, extracts all URLs, and automatically groups them into sections based on URL patterns (blog, tools, docs, etc.).
The Fetch button calls your page's URL server-side and automatically pulls the page title and meta description into the form fields — so you do not have to type them manually.

How to deploy
Save the downloaded file as llms.txt and upload it to your website’s root so it’s accessible at yourdomain.com/llms.txt. AI crawlers including ChatGPT, Perplexity, and Claude discover and read it automatically.
llms.txt format reference
# H1Brand name — required, one per file> textTagline as blockquote## H2Section grouping (Tools, Blog, Docs…)- [T](url): dPage link with optional descriptionEnter your brand name, tagline, and a two-to-three sentence description of what your site does. This becomes the header block of your llms.txt and is the first thing AI crawlers read.
Choose SaaS, Blog, Agency, or E-commerce to prefill the form with realistic example content. Swap in your own details or use it as a structural starting point.
Paste your sitemap.xml URL and click Import. The tool fetches it server-side, extracts all page URLs, and auto-groups them into sections — Blog, Tools, Docs, About, Legal, and more.
Hit the Fetch button on any page entry. The tool visits the live URL server-side and pulls the title tag and meta description into the form automatically — no manual copying required.
The right panel updates in real time as you type. Syntax colouring shows how each element maps to the llms.txt format: brand name in primary, tagline in purple, sections in green.
Click Download to save the file, then upload it to your site's root directory. AI crawlers including ChatGPT, Perplexity, and Claude discover and read it at yourdomain.com/llms.txt.
llms.txt is a plain-text Markdown file placed at yourdomain.com/llms.txt. It gives AI language models a curated map of your site — your brand name, a short description, and a list of your most important pages grouped by topic.
Without it, AI crawlers must infer what your site is about from raw HTML. With it, you control the narrative: which pages get surfaced, how sections are labelled, and what one-sentence summary describes each page. Sites with a clear llms.txt are more likely to be cited accurately in ChatGPT, Perplexity, and Google AI Overviews.
