What is the Sophyx llms.txt Generator?
A free tool that writes an llms.txt file for your website. It reads your homepage and sitemap, picks the pages that explain your business best, and turns them into a short Markdown file you can publish at yourdomain.com/llms.txt. AI tools can read that file to understand what you do.
It is one part of being easy for AI to read, next to clear pages, schema markup, and a robots.txt that lets AI crawlers in.
Example llms.txt file
This is the kind of file you get, here for a made-up physio clinic in Toronto.

How it works
Step 1
Enter your website
Paste your homepage address. The tool reads your homepage and looks for your sitemap.
Step 2
It picks your main pages
It keeps the pages that explain your business, such as services, prices, location and FAQ, and skips the rest.
Step 3
Copy your file
You get a ready-to-edit llms.txt. Review it, then publish it at the root of your site.
What you get
Only the pages that matter
Services, prices, location, contact and FAQ. Tag pages, archives and old offers are left out.
A summary AI can quote
One plain paragraph that says what you do, where, and for whom.
No account needed
No signup, no card and no email. Copy the file and go.
Who it's for
- Local businesses that want AI tools to find their services, hours and location.
- Founders and marketers who want a clean summary of their site.
- Agencies setting up AI-ready sites for several clients.
- SaaS teams with docs, pricing and support pages to point at.
What it often finds
- No llms.txt file at all.
- A sitemap full of pages that don't explain the business.
- A homepage that never says plainly what you do.
- Key pages, like prices or hours, that are hard to find.
llms.txt, explained
Why create an llms.txt file?
Websites are built for people: menus, pop-ups, scripts and long archives. An AI tool trying to understand you quickly has to dig through all of that.
An llms.txt file gives it a shortcut: a plain table of contents that says who you are and which pages matter. It adds to your homepage, sitemap and schema markup. It does not replace them.
What should an llms.txt file include?
For most businesses:
- Your business name
- A one-paragraph summary
- Main service or product pages
- Prices
- Location, hours and contact
- FAQ
What to leave out
- Tag and archive pages
- Old offers and landing pages
- Internal search pages
- Private pages
A short, clear file is more useful than a long one.
Is llms.txt the same as robots.txt or sitemap.xml?
No. robots.txt tells crawlers where they may not go. A sitemap lists every page so search engines can find them. llms.txt picks the few pages that best explain your business.
Most sites should have all three.
Will this guarantee AI visibility?
No. No file can make ChatGPT, Gemini or any other assistant name you. llms.txt helps AI read your site.
Being named also depends on clear pages, facts that agree everywhere, and what other sites say about you.
After you generate your file
- 1.Read the summary and fix anything that is off.
- 2.Remove pages that don't help. Add any that are missing.
- 3.Publish it at https://yourdomain.com/llms.txt
- 4.Update it when you add or remove important pages.
- 5.Check your robots.txt and schema markup with the other free tools.

Questions people ask
Is the Sophyx llms.txt Generator free?
Yes. It is free at app.sophyx.io/llms-txt-generator, with no signup, no card and no email. Sophyx also has paid plans for ongoing AI visibility work, but you don't need one for this.
Do I need to create a Sophyx account?
No. The generator works without an account. If you later want Sophyx to check and fix what AI says about you, you can sign up at app.sophyx.io/signup.
What is an llms.txt file?
A short Markdown file at the root of your site that gives AI tools an overview: a summary of your business and links to your key pages.
Where should I publish my llms.txt file?
At the root of your domain: https://yourdomain.com/llms.txt. Then use the free robots.txt checker to make sure AI crawlers can reach the pages it lists.
Will llms.txt improve my Google rankings?
No, not directly. Google does not use it as a ranking factor. It helps AI tools read your site, and that is all it claims to do.
Does this replace SEO?
No. You still need clear pages, correct facts, and a site search engines can crawl. llms.txt is one small addition.
Does this replace sitemap.xml?
No. A sitemap lists every page for search engines. llms.txt picks the few that best explain your business. Keep both.
Does this replace robots.txt?
No. robots.txt controls which crawlers may visit which pages. llms.txt is a guide to your content. They do different jobs.
Can I edit the generated file?
Yes, and you should. The tool gives you a good first draft, but you know your business and which pages matter most.
How often should I update my llms.txt file?
Whenever you add, remove or change important pages, such as a new service or new prices.
How does Sophyx choose which pages to include?
It reads your homepage and sitemap, then keeps the pages that best explain what you do: services, products, prices, location, contact, FAQ and docs. The goal is a short list, not a second sitemap.
What other free Sophyx tools work well with llms.txt?
The llms.txt validator checks the file once it is live. The schema markup generator labels your business facts. The robots.txt checker makes sure AI crawlers can get in. The brand AI visibility checker shows what ChatGPT and Gemini say about you. All of them are in the AEO Free ToolKits hub.
How does llms.txt relate to structured data and the AI Guide?
Structured data (JSON-LD) labels single facts, like your address and hours, inside your pages. llms.txt is a plain guide to the whole site. They work well together. Sophyx's AI Guide goes a step further: an AI-readable version of your site on your own subdomain.
Can llms.txt help prevent competitive brand displacement?
Not on its own. When AI names a competitor instead of you, the cause is usually unclear pages, facts that disagree across the web, or more mentions for the competitor. llms.txt helps with the first. The free check at app.sophyx.io/brandanalysis shows which questions you are losing.
What is Answer Engine Optimization (AEO) and how does this tool help?
AEO means making your business easy for AI assistants such as ChatGPT, Gemini, Claude and Perplexity to find, understand and name in their answers. This tool writes a short file that tells AI tools what your business does and where your important pages are. It is one fix you can make today. To see what AI actually says about you, run the free check at app.sophyx.io/brandanalysis.
How is AI SEO different from traditional SEO?
SEO is about ranking in a list of links on Google and Bing. AI SEO (also called AEO or GEO) is about what the AI says when it answers: whether it names you, and whether it gets your facts right. AI builds that answer from everything the web says about you, so clear pages, labelled facts and mentions on other sites all count. The same work helps both.
Which AI engines and platforms does Sophyx optimize for?
The fixes help on every assistant, because ChatGPT, Gemini, Claude, Perplexity, Copilot and Google AI Overviews all read the same public web. What we track is narrower: ChatGPT and Gemini, including Google AI Overviews. Your own website matters most, and sites like LinkedIn, Reddit and review sites also shape what AI says about you.
How does this free tool connect to Sophyx's AI visibility platform?
This tool checks or fixes one thing. Sophyx does the rest: it asks ChatGPT and Gemini the questions your customers ask, shows you where you are missing or described wrong, writes the fixes, and publishes them on your own website once you approve. Start with the free check at app.sophyx.io/brandanalysis.
Does Sophyx offer help for marketing agencies?
Yes. Through the Agency Partner Program, agencies run Sophyx for every client under their own brand, with white-label, client-ready reports and priority support. Many agencies use these free tools for a quick first look at a client's site.
