llms.txt Generator
Create an llms.txt file that gives AI systems clear instructions about your content. Free, runs entirely in your browser.
What is an llms.txt file?
llms.txt is a plain-text file placed at the root of a website (https://yoursite.com/llms.txt). It gives large language models and AI answer engines clear, human-readable instructions about how they may use the site’s content. Think of it as a friendly counterpart to robots.txt that is written for AI systems rather than traditional crawlers.
Why llms.txt matters for GEO
Generative Engine Optimization (GEO) is about making your content easy for AI systems to find, understand, and cite correctly. An llms.txt file helps by:
- Stating whether AI systems are welcome to use your content
- Providing a preferred way to cite or attribute your work
- Pointing AI systems toward your most important or authoritative pages
- Reducing the chance of incorrect or incomplete citations
It is still an emerging convention, but many sites and GEO tools already look for it.
How to use this generator
- Enter your site name and a short description.
- Add the citation format you prefer (name + URL works well).
- Choose how freely AI systems may use your content.
- Optionally list important sections or pages.
- Copy the generated text or download the file as
llms.txt. - Upload the file to the root of your website so it is reachable at
https://yoursite.com/llms.txt.
Best practices
- Keep the file short and clear.
- Use plain language — AI systems read it as text.
- Update it when your preferred citation or policy changes.
- Combine it with a well-structured site, good robots.txt rules for AI crawlers, and clear content.
Frequently asked questions
Is llms.txt required?
No. It is optional. Many sites perform well in AI answers without one. It simply gives AI systems clearer guidance.
Does every AI system read llms.txt?
Not yet. Support is growing, but it is not universal. It is still worth adding because the cost is near zero and the upside is clearer attribution.
Where should I put the file?
In the root of your domain, exactly like robots.txt: https://yoursite.com/llms.txt
Can I block AI training with this file?
You can state your preference. Whether a particular model respects it depends on that model’s policy. For stronger control, also review your robots.txt rules for AI crawlers.
