Short answer: llms.txt is a short text file at the root of your site that lists your best pages for AI tools. It is a proposed convention, not a confirmed ranking or citation factor. You do not need one, but it takes a few minutes to make and does no harm.
Why create an llms.txt file?
Short answer: llms.txt gives AI tools a short, clean list of your best pages. It takes a few minutes, costs nothing and does no harm. Its effect is not confirmed, so treat it as a small extra, not a strategy.
Real use case: Your site has 200 pages, but 10 of them explain your business best. You list those 10 in llms.txt with one line each.
Benefits
- A clear summary of who you are and what you do
- Your best pages in one place
- A file ready in minutes, with no coding
Why use this tool
- Free, no signup.
- Private: the file is built in your browser and nothing is uploaded
- Simple format: site name, summary, key pages and an Optional section
What llms.txt is
- A plain text file that loads at yourdomain.com/llms.txt
- A short, human-readable summary written for language models
- A list of your most important pages, with a note on each
What it is not
- It does not replace robots.txt, which controls crawling.
- It does not replace sitemap.xml, which lists URLs.
- It does not guarantee any AI tool will read it or cite you.
Create one in 4 steps
- Open the tool. Use my free llms.txt Generator.
- Enter your site name and a one-sentence summary.
- Add your most important pages, one per line. Add less important ones in the Optional section.
- Copy or download the file and upload it to your site root, so it loads at https://example.com/llms.txt.
Common mistakes
- Listing every page instead of the best ones
- Writing marketing hype instead of a plain summary
- Putting the file in a folder instead of the site root
- Expecting it to improve rankings
