llms.txt and upload to your server root so it's accessible at yourdomain.com/llms.txt. For WordPress, upload via FTP or File Manager to the public_html folder.
What Is an llms.txt File?
An llms.txt file is a plain-text, Markdown-formatted file placed at the root of your domain that tells AI language model crawlers which pages matter most. It sits alongside robots.txt and gives systems like GPTBot, ClaudeBot, and PerplexityBot a prioritised map of your content.
As AI search engines now handle more than 50 percent of all queries globally, giving AI systems a clear content hierarchy has become a practical necessity for visibility. This free llms.txt generator builds a correctly formatted file in under two minutes with no coding required.
Where robots.txt acts as a gate controlling crawler access, llms.txt acts as a signpost directing AI models toward your highest-value pages. Together the two files form the foundation of modern AI search optimisation.
Why Your Site Needs an llms.txt File
AI-referred web sessions grew 527 percent between January and May 2025 according to SparkToro research, and ChatGPT now has over 900 million weekly active users. Without an llms.txt file, AI crawlers must infer your content hierarchy from links and schema alone. That increases the risk of AI systems surfacing outdated pages or low-authority posts instead of your flagship resources.

How to Use This llms.txt Generator
Enter your site name and a one to two sentence description. This description becomes the entity definition AI models use when attributing content to your brand. Next, add the URLs and short titles of your most important pages including your best-performing articles, key service pages, and cornerstone content. Optionally add any pages you want AI crawlers to skip, such as login pages, search results, or thin archives.
Click Generate to produce your llms.txt output. Copy the text, save it as a plain .txt file named exactly llms.txt, and upload it to your domain root at https://yourdomain.com/llms.txt. On WordPress, upload via FTP to the public_html folder or use a file manager plugin. Confirm it loads correctly before submitting your sitemap for recrawl.
llms.txt vs robots.txt: Key Differences
| File | Purpose | Controls | Audience |
|---|---|---|---|
| robots.txt | Crawler access gate | Which URLs crawlers can visit | All crawlers |
| llms.txt | Content priority guide | Which pages AI should prioritise | AI language models |
| sitemap.xml | URL discovery map | Which URLs exist and when updated | All crawlers |
Use all three files together. robots.txt controls access, llms.txt controls AI priority, and sitemap.xml enables discovery. A site with all three files gives AI search engines the clearest possible picture of your content and earns more consistent citation across ChatGPT, Perplexity, and Google AI Overviews.
