Paste in your site’s key pages and this free tool builds a clean, spec-compliant llms.txt file — the plain-text map that ChatGPT, Perplexity, Claude and other AI engines can read to understand your site. No signup, no upload: everything runs in your browser.
One honest caveat up front, because we’re a GEO Lab: llms.txt is a proposed standard, not a guaranteed ranking lever. Some engines read it, Google says it doesn’t, and our analysis of 137,000 sites shows adoption is still early. It’s cheap insurance, not a silver bullet. Generate the file below, then read the honest take underneath.
llms.txt Generator
Pick a template or fill in the fields — the preview below updates live as you type. Reorder sections with the arrows so your most important content comes first. 100% in-browser — nothing is uploaded.
Start typing above — your llms.txt appears here live.
Based on the llms.txt spec. Place the generated file at https://yourdomain.com/llms.txt. Built by GeoParrot — the GEO Lab.
How to use this llms.txt generator
- Pick a template or start blank. The SaaS, Blog, Docs and E-commerce presets prefill sensible sections and links — swap in your own domain and pages. Then name your site and write a one-line summary: these become the title and the blockquote, the first two things an AI model reads.
- Add your most important links and put them first. Group pages under headings like Docs, Product, or Blog, and use the arrow buttons to reorder — engines read top-down, so lead with your key content. Put lower-priority links under a section called Optional; the spec treats that as content an engine can skip when short on context.
- Copy or download. The preview updates live as you type, and the tool flags missing summaries or malformed URLs before they hurt your file. Save it as
llms.txtand upload it to your domain root so it lives athttps://yourdomain.com/llms.txt.
What is an llms.txt file?
llms.txt is a proposed standard — a single Markdown file at your site root that gives AI models a clean, curated map of your most important pages, without the navigation, ads, and scripts that clutter a normal HTML page. Think of it as a sitemap.xml written for large language models instead of search crawlers. For the full background, read our complete 2026 guide to llms.txt, and if you’re on WordPress, our step-by-step guide to adding llms.txt to WordPress.
Does llms.txt actually work? An honest take
We test GEO claims instead of repeating them, so here’s the unvarnished version. Adoption is real but early: our look at 137,000 websites found most sites still don’t have one, and Google has publicly confirmed it doesn’t use llms.txt for its AI features. Some answer engines and dev-tool crawlers do read it. The practical stance: an llms.txt file takes ten minutes to publish, costs nothing, and can only help — but treat it as one small tile in a broader answer engine optimization (AEO) strategy, not the whole game.
Frequently asked questions
Where do I put the llms.txt file?
At the root of your domain, so it resolves at https://yourdomain.com/llms.txt — the same place your robots.txt lives. On WordPress, upload it via your host’s file manager or a plugin; see our WordPress walkthrough.
Is this llms.txt generator free?
Yes. It’s completely free, requires no signup, and runs entirely in your browser — none of your data is sent to a server.
What’s the difference between llms.txt, robots.txt, and sitemap.xml?
robots.txt tells crawlers what they may access; sitemap.xml lists your URLs for search engines; llms.txt gives AI models a curated, human-readable summary of your best content. They complement each other rather than replace one another.
Does Google use llms.txt?
No. Google has said it does not use llms.txt for AI Overviews or Gemini. We cover what that means in this breakdown. Other engines and AI dev tools may still read it, which is why it remains worth publishing.
What order should the sections in llms.txt be in?
Most important first. AI engines read the file top-down and may truncate when context is tight, so lead with the sections you most want represented — docs or core product pages — and keep nice-to-have links in an Optional section at the end. This generator has up/down arrows on every section and link so you can set that order.
