Free llms.txt builder
Build a starting llms.txt file
Fill in a title, short context, and the resource links you want to list, and this page builds a valid llms.txt file for you to review, edit, and publish.
This is a content-authoring tool, not a live check of your site. It does not run against a real domain and does not prove that any answer engine reads, prefers, indexes, or cites the file once published.

- [Getting started](https://example.com/docs/getting-started)
- [API reference](https://example.com/docs/api)This is a generated starting point, not a verified fix and not a file already published on your site. Review every line, then publish it yourself.

Each tool looks at a different layer of AI discovery readiness. Use them together, or open the complete audit for all of it at once.
Enter a public hostname to test whether its deployed robots.txt policy allows, blocks, or has no matching restriction for documented AI crawler tokens at the root path.
Check the live /llms.txt file on a public website, or paste a draft to validate it before deployment. Both modes use the same rules for title, introduction, sections, links, malformed Markdown, duplicate destinations, and insecure URLs.
Compare visible homepage identity with structured entities, graph identifiers, sameAs identity references, and trust signals.
Check the actual public recipe page for Recipe JSON-LD, Google-required fields, and selected recommended properties.
Choose a declared policy goal and this page builds robots.txt groups for the documented AI crawler tokens that goal has an explicit preference for, which you can review, edit, and publish.
Build Organization JSON-LD with a reusable #organization @id and optional identity-reference URLs.
Paste a prompt and the source an AI answer cited. See which public evidence differs from your site, what is worth testing, and what no external audit can prove.
Compare the business name, phone, email, address, and official profiles stated on your homepage, About page, Contact page, and JSON-LD, and see where any value differs.
Compare the new version of a site or page with the current live one under the same audit rules, and see regressions in crawler access, content, and identity before you launch.
How this builder works
From a few fields to a file you can publish
Everything runs locally in your browser — there is no server round-trip and nothing is stored.
- 1
Enter a title — this becomes the file’s top-level heading.
- 2
Add short, factual system context — this becomes the introductory blockquote.
- 3
List the resource links you want included, with a label and URL for each.
- 4
Review the live preview, then copy or download the generated file.

What remains your responsibility
- The generated file is a starting point; review every line before publishing it.
- This tool does not verify that the linked URLs exist or are reachable.
- Publishing an llms.txt does not prove that any provider reads, prefers, indexes, or cites it.
- It does not check or replace an existing llms.txt — use the llms.txt checker for that.

Questions about this builder
Does publishing this file guarantee AI visibility?
No. This tool only generates the file locally in your browser. It does not check your live site and cannot prove that any provider reads, prefers, indexes, or cites the file once you publish it.
Where do I put the generated file?
llms.txt is conventionally published at the root of your domain, for example https://example.com/llms.txt. Publishing is your responsibility — this tool does not deploy anything.
Can I check an llms.txt file I already have instead?
Yes. Use the llms.txt checker to inspect a deployed file’s structure, links, and review items instead of building a new one.
