llms.txt generator
Generate a polished llms.txt file so AI crawlers know what you sell and which pages matter.
One sentence. This becomes the > quoted line right under the site name — it's what crawlers latch onto first.
A 2-3 sentence elevator pitch. Tells the LLM who you serve and what makes you different.

Self-serve, no contract. ## Docs - [Getting started](https://acme.example/docs/getting-started): Install Acme in under three minutes. ## Optional - [Pricing](https://acme.example/pricing): Plans, fees, and what's included on each tier.
Save the downloaded file to the root of your domain — e.g. https://yourdomain.com/llms.txt. AI crawlers fetch this file directly; no DNS or schema configuration needed.
What is llms.txt?
llms.txt is a small Markdown file you place at the root of your domain (e.g. https://yourdomain.com/llms.txt) that tells large language models which content on your site matters and how it's organized. Think of it as robots.txt for the AI Search era — a curated table of contents instead of a crawl-allow-list.
Major LLM providers (OpenAI, Anthropic, Google, Perplexity) increasingly use page-level signals like canonical content, structured data, and now llms.txt to decide which sources to cite when answering user queries. A clean llms.txt file improves the chance that the LLM picks your docs and key pages over a competitor's.
Why every site should have one
Without an llms.txt, an AI crawler has to guess which pages on your site are canonical references vs. pagination, archive, or low-signal pages. With one, you tell the model directly: “these are the docs I want you to read first”. The benefit shows up in three places:
- Citation accuracy. When ChatGPT or Perplexity quote your brand, they pull from the right page — not last year's blog post.
- Coverage. Pages you list explicitly are far more likely to be ingested during the model's next training or retrieval pass.
- Brand voice. The tagline (the
>line) becomes how the LLM describes you in cited answers.
How to deploy llms.txt
- Use the form above to fill in your site name, tagline, and the pages you want LLMs to prioritize. Group docs separately from optional/marketing pages.
- Click Download llms.txt to save the file.
- Upload it to the root of your domain so it's accessible at
/llms.txt. On most hosts you can drop it into thepublic/(Next.js),static/(Hugo, Gatsby), or document root (cPanel, Hostinger) directory. - Verify it loads by visiting
https://yourdomain.com/llms.txtin a browser.
That's it. There's no DNS record, no schema markup, no verification step. The file is fetched directly by AI crawlers the same way robots.txt is.
FAQ
Is llms.txt an official standard?
It's a community-driven proposal originally published at llmstxt.org. It's not a W3C-ratified standard yet, but major LLM providers have publicly indicated that they read it and weigh it in retrieval-augmented generation. Like robots.txt before it, the standard is being defined by adoption.
Does llms.txt replace robots.txt or sitemap.xml?
No. robots.txt controls crawl access, sitemap.xml lists every URL on your site, and llms.txt curates the small subset of pages you want LLMs to read first. They serve different purposes and most sites should have all three.
How long should my llms.txt be?
Short. The whole point is that it's a curated index, not a dump. Most well-tuned files are 30 to 80 lines — your brand pitch, then 5 to 20 hand-picked links. Listing every blog post defeats the purpose; that's what your sitemap is for.
Will llms.txt help my Google rankings?
Indirectly. Google's traditional crawler doesn't use llms.txt, but Google's AI Overviews increasingly cite the same pages that ChatGPT and Perplexity cite, so improving your AI Search visibility flows back into mainstream search visibility over time.
Can I update llms.txt later?
Yes — it's just a file. Re-upload whenever you publish significant new docs or change your positioning. AI crawlers re-fetch it on their normal schedule.
Do I need to list every page on my site?
No, and you shouldn't. List only the pages that genuinely answer common questions about your product or industry. Pricing, getting-started docs, and your top blog explainers usually make the cut. Long-tail content pages are better served via your sitemap.
