Free llms.txt Generator
Enter a domain and get a ready-to-use llms.txt - your pages, discovered from the sitemap and summarized by AI, in the format AI crawlers expect. Free, no signup.
What is llms.txt?
llms.txt is a simple Markdown file you place at the root of your site (yoursite.com/llms.txt) that tells AI assistants - ChatGPT, Claude, Perplexity and others - what your site is about and which pages matter. Think of it as a curated map written for language models instead of search-engine spiders. It lists your key pages with a short description of each, so an AI answering a question about your business can find and cite the right page instead of guessing from raw HTML.
Why does your site need an llms.txt?
AI-powered search engines like ChatGPT, Perplexity, Claude and Google AI are already reading your site to answer questions - whether or not you help them. An llms.txt helps your site get found, understood and cited by them. Without one, they crawl messy HTML full of nav bars, cookie banners and ads, and often summarize you wrong or miss your best pages; an llms.txt hands them a clean, accurate summary on a plate. As more people search through AI instead of traditional search, being correctly represented in those answers is becoming its own channel - and an llms.txt is the cheapest way to influence it.
What goes in a good llms.txt?
The format is deliberately minimal: an H1 with your site name, a one-line blockquote summary, then H2 sections (Docs, Blog, Products, etc.) each listing pages as Markdown links with a short description. Keep descriptions concrete and specific - "Pricing for our three plans with feature comparison" beats "Our pricing page." Link only pages worth citing; an llms.txt is a highlight reel, not a full sitemap. This generator produces exactly that structure, which you can edit before publishing.

How AI crawlers use llms.txt
When an AI assistant or its crawler visits your domain, a growing number check for /llms.txt first - much like search engines check robots.txt and sitemap.xml. The file gives them a fast, low-noise overview: what you do and where the important content lives. It does not replace your real pages (the assistant still reads the linked pages for detail), but it steers attention to the right ones and reduces the chance of being misrepresented. The standard is young, so adoption varies - but the cost of adding the file is near zero and it only helps.
How to use this generator
Enter your domain and click Generate. The tool finds your pages from your sitemap (or, if you have none, from your homepage links), respects your robots.txt, summarizes the most important pages with AI, and assembles a standard llms.txt. Review and edit the summaries - AI gets you 90% there, your judgment does the last 10% - then copy or download the file and upload it to your site root so it is reachable at yoursite.com/llms.txt.
Frequently asked questions
Is this llms.txt generator free? +
Yes - completely free, no signup. It summarizes up to 20 of your most important pages per generation. If your site is larger, the file still gives AI assistants a strong overview of your key content.
Where do I put the llms.txt file? +
At the root of your domain, so it is reachable at yoursite.com/llms.txt - the same place your robots.txt lives. Download the generated file and upload it there via your host, CMS, or static site.
How is llms.txt different from robots.txt or sitemap.xml? +
robots.txt tells crawlers what they may access; sitemap.xml lists every URL for search engines. llms.txt is different: it is a short, human-written (or AI-drafted) summary aimed at language models, highlighting only your important pages with descriptions - quality over completeness.
Does adding an llms.txt guarantee more AI traffic? +
No - nothing guarantees AI traffic, and the standard is still emerging, so not every assistant reads it yet. What it does is make the assistants that do read it understand and represent your site more accurately. It is a cheap, low-risk improvement, not a magic switch.
How often should I update my llms.txt? +
Refresh it when your important pages change - a new product, major docs, or a restructured site. For most sites a few times a year is plenty. Re-run this generator and re-upload the file whenever your key content shifts.
