llms.txt Generator — Free AI Crawler Readiness Tool

Build a free llms.txt file for your small business website, then check it for AI crawler readiness before you publish — fill in the fields below, no signup required.

How it works

Fill in your site name and one-line summary.
Add links to the pages AI should know about.
Copy or download the file and upload it to your site root.

Your llms.txt

Fill in the fields on the left — your file appears here.

The file helps AI systems orient, but does not guarantee citation or ranking.

What llms.txt is, and why build one

llms.txt is a short markdown file published at your site's root — https://yourdomain.com/llms.txt — that gives AI systems a plain-language map of your business: who you are, what you offer, and which pages matter most. It follows the community format set out at llmstxt.org: a title, a one-line summary, optional context, and sections of markdown links.

It is not a substitute for robots.txt. robots.txt decides which crawlers may access your site at all; llms.txt only helps a crawler that already has access orient faster once it gets there. Building the file does not guarantee that ChatGPT, Gemini, Perplexity or any other assistant will cite your business — inclusion is decided by each platform. What it can do is remove one common reason a small business site is harder for AI systems to summarize correctly.

How to fill in each field

Site name (H1)

The first line of your file is a level-1 markdown heading with your business name — the same name you'd want an AI assistant to use when it mentions you. Match it exactly to your site; skip taglines and keywords here.

One-line summary

A single sentence under the title, written as a markdown blockquote, that states what your business does in plain language. Treat it as the one line you'd want quoted back if an assistant summarized your site.

Short context

An optional sentence or two of extra detail — who you serve, and what the sections below cover. It helps an assistant tell a general services page apart from a specialized one without reading your whole site.

Section heading

A level-2 heading such as Docs, Services or Pricing that groups related links. Most small business sites need two or three sections at most — you don't need to mirror your entire main menu.

Link text

The visible label for each link, written the way a person would read it out loud — "Pricing", not "pricing-page-2026". This is the anchor text an assistant sees, so keep it descriptive.

URL

The full, absolute address of the page, starting with https://, not a relative path. Link only to pages that return a normal response for visitors — a link behind a login wall or a broken page is worse than no link at all.

Example of a complete llms.txt file

A short, accurate file works better than a long, padded one. Here's a working example for a small analytics business:

# Acme Analytics
> Privacy-first analytics for indie developers.

Acme helps small teams understand traffic without cookies.

## Docs
- [Getting started](https://acme.dev/docs/start)
- [API reference](https://acme.dev/docs/api)

## Services
- [Pricing](https://acme.dev/pricing)
- [Contact](https://acme.dev/contact)

Notice what it leaves out: no tracking parameters, no PDF exports, no pages that require a login. Five to fifteen links is enough for most small business sites.

Where to publish it once it's built

The file has to live at your domain root — https://yourdomain.com/llms.txt — served as plain text or markdown, not tucked inside a subfolder. The exact steps depend on your platform:

Whichever platform you use, confirm AI crawlers are not blocked by your security plugin, CDN or robots.txt first — llms.txt only helps a crawler that can already reach your pages.

File built? Run Express Check — free — to see whether AI crawlers can actually reach it and the rest of your site.

Frequently asked questions

Is this llms.txt generator really free?

Yes. Building and downloading your file needs no signup or payment. Express Check, which reports whether AI crawlers can reach it, is also free — you only pay if you later order a Starter or Pro file package.

Do I need to allow AI crawlers before I publish llms.txt?

Yes. The file only helps a crawler that can already reach your pages. Check robots.txt and any CDN or security rules first, or run Express Check to see which AI bots are currently blocked.

How many links should my llms.txt include?

Five to fifteen is typical for a small business site. List your strongest pages — pricing, services, docs, contact — rather than your entire sitemap.

Will publishing llms.txt get my business cited by ChatGPT or Gemini?

No tool, including this one, can guarantee that. llms.txt is one orientation signal among several; citation still depends on content quality, crawl access, and each platform's own decisions.

Can I edit the file after I download it?

Yes. It's a plain markdown file — open it in any text editor, update links when your pricing or pages change, and re-download or rebuild it here whenever you need to.

What is the difference between llms.txt and llms-full.txt?

llms.txt is meant to stay a short index. llms-full.txt is an optional, longer file with expanded content for large documentation sites — most small businesses only need the short file this generator builds.
