Free LLMs.txt Generator
Create an llms.txt file that helps AI models, search engines, and assistants understand your website. Enter your URL and email to generate a ready-to-use file in seconds — no account, no cost. It is a simple, practical first step toward AI search visibility (GEO).
What is llms.txt?
llms.txt is a lightweight, plain-text file that lives at the root of your website (for example yourbrand.com/llms.txt) and gives AI systems a clear, structured summary of who you are, what you offer, and which pages matter most. Think of it as a curated briefing document written specifically for large language models.
It is similar in spirit to robots.txt and sitemap.xml, but instead of controlling crawlers or listing every URL, it highlights the handful of pages and facts you most want an AI model to understand and cite. As tools like ChatGPT, Perplexity, Claude, and Google's AI Overviews increasingly answer questions directly, giving them accurate context becomes as important as ranking in classic search results.
Why llms.txt matters for AI search and GEO
Search behaviour is splitting between traditional results and AI-generated answers. When someone asks an assistant "who's a good SEO agency near me?" the model synthesises an answer from whatever it can read and trust. An llms.txt file helps you influence that answer by:
- Reducing hallucinations. A concise, accurate summary means models are less likely to misdescribe your business.
- Improving citation odds. Clear, quotable statements about your services make it easier for AI answers to reference your site by name.
- Prioritising the right pages. You decide which URLs represent you, rather than leaving models to guess from a sprawling site.
- Future-proofing at near-zero cost. Adoption is growing; publishing one now carries no SEO risk and positions you early.
llms.txt is one lever among many. Getting cited consistently in AI answers is the goal of generative engine optimization (GEO), which combines authoritative content, structured data, and technical readability. Read more on the 365Digital blog.
How to create an llms.txt file
- 1
Enter your website URL
Paste the full homepage URL of the site you want an llms.txt file for, for example https://yourbrand.com. The generator reads your public pages to understand your structure.
- 2
Add your email address
Enter a valid email so we can deliver the file and keep the tool free of abuse. You can generate up to three files per email each day.
- 3
Generate the file
Click Generate. In a few seconds the tool produces a structured llms.txt file summarising who you are, what you offer, and which pages matter most to AI models.
- 4
Review and edit the output
Check the generated summary and page list. Tighten the descriptions, remove anything irrelevant, and make sure your highest-value pages (services, pricing, contact) are included.
- 5
Upload it to your site root
Save the file as llms.txt and upload it to the root of your domain so it is reachable at https://yourbrand.com/llms.txt, exactly like robots.txt.
llms.txt vs robots.txt vs sitemap.xml
These three root-level files do different jobs. You should have all three — they complement rather than replace each other.
| File | Audience | Purpose |
|---|---|---|
| llms.txt | AI models & assistants | Summarises your most important content in plain language so AI can understand and cite it. |
| robots.txt | Search-engine crawlers | Tells crawlers which URLs they are allowed or disallowed to access. |
| sitemap.xml | Search-engine crawlers | Lists all indexable URLs to help crawlers discover your pages. |
Example llms.txt file
A good llms.txt file leads with a one-line description, adds a short summary, then lists your priority pages with brief context. Here is a simple example:
# Your Brand > One-line description of what your company does and who it helps. Your Brand helps [audience] achieve [outcome] through [services]. Founded in [year], based in [location], serving clients [area]. ## Core Pages - [Services](https://yourbrand.com/services): Overview of what we offer. - [Pricing](https://yourbrand.com/pricing): Plans and how they work. - [Contact](https://yourbrand.com/contact): How to get in touch. ## Content - [Blog](https://yourbrand.com/blog): Guides on [your topics]. - [Case Studies](https://yourbrand.com/case-studies): Real client results.
The generator above produces a first draft in this shape from your live site — you then refine the wording and page selection before publishing.
Frequently asked questions
What is an llms.txt file?+
llms.txt is a plain-text file placed at the root of your website (yourdomain.com/llms.txt) that gives large language models a clear, structured summary of your site: who you are, what you offer, and which pages are most important. It helps AI systems understand and cite your content accurately.
Is this llms.txt generator free?+
Yes. The 365Digital llms.txt generator is completely free. You can create up to three files per email address per day, with no account required.
Where do I put the llms.txt file?+
Upload it to the root directory of your domain so it is accessible at https://yourdomain.com/llms.txt. It sits in the same place as your robots.txt and sitemap.xml files.
How is llms.txt different from robots.txt?+
robots.txt tells search-engine crawlers which URLs they may or may not access. llms.txt does the opposite job for AI: instead of restricting crawlers, it gives language models a curated, human-readable summary of your most important content so they can represent it correctly.
Will llms.txt help my site rank in AI search?+
llms.txt is not a ranking guarantee, but it makes your site easier for AI systems such as ChatGPT, Perplexity, Claude, and Google AI Overviews to parse and cite. Combined with strong content, structured data, and clear information architecture, it improves your chances of being surfaced and cited in AI answers — the core of generative engine optimization (GEO).
Do AI models actually read llms.txt?+
Support is still emerging. llms.txt is a proposed open standard that a growing number of AI tools and crawlers are beginning to respect. Publishing one is low-effort and future-proofs your site as adoption grows, at no risk to your existing SEO.
How often should I update my llms.txt file?+
Update it whenever your key pages, services, or positioning change — typically every few months, or immediately after a major site update or new service launch. Keeping it current ensures AI models describe your business accurately.
Can I edit the generated file?+
Absolutely, and you should. Treat the generated file as a strong starting point: refine the descriptions, prioritise your most valuable pages, and remove anything low-value before publishing it.
