The llms.txt yoursite is missing.

Generate a clean, machine-readable map of your site for AI crawlers — an optional GEO artifact that sits behind crawlable HTML, schema, and authority. We pull your sitemap, extract real titles and descriptions, and ship a validated llms.txt — in seconds, no signup.

02Why it matters

AI crawlers are reading now. Give them the right map.

llms.txt is an optional GEO artifact. The real work is done by crawlable HTML, server-side rendering, schema, and authority — llms.txt is a clean bonus once those are in place, not a foundation. Google says it neither helps nor hurts in Search; treat it as low-effort, low-risk.

Guide how AI reads your site

ChatGPT, Claude, and Perplexity get a clean, structured summary of what you offer — instead of guessing from random pages.

Reduce guesswork about your brand

When AI does read it, it has your own summary instead of inferring pricing and features from stale third-party pages.

Ship in two minutes

Generate, upload to your root directory, done. No code changes, no CMS plugins, no redeploys.

A clean bonus, not a bet

A proposed standard, not a confirmed ranking signal — most llms.txt files get no crawler requests. Cheap to ship, so do it after crawlable HTML, schema, and authority.

Defined

What is llms.txt?

llms.txt is a proposed standard by Jeremy Howard (Answer.AI) that helps AI assistants like ChatGPT, Claude, and Perplexity understand your website. Like robots.txt tells search engines which pages to crawl, llms.txt tells language models what your site is about — in their native language, markdown.

Within the practice of generative engine optimization (GEO), llms.txt is the optional one. The signals that actually move citations come first: crawlable HTML, server-side rendering, Schema.org JSON-LD, and real authority. llms.txt is a clean bonus once those are in place — not a substitute for them.

04Questions

Things people ask before they generate.

01

What is an llms.txt file?

llms.txt is a proposed standard that helps AI assistants like ChatGPT, Claude, and Perplexity understand your website. Similar to robots.txt for search crawlers, llms.txt is a machine-readable file you place at your root directory that tells language models what your site contains, in markdown — their native format.
02

Where do I put the llms.txt file?

Upload it to your website's root directory so it is accessible at yourdomain.com/llms.txt. Vercel, Netlify, WordPress, Shopify, and most static hosts support this. For WordPress, use a plugin or drop it in the public folder.
03

How often should I update my llms.txt?

Regenerate when your site structure changes — new product lines, major content sections, rebrands. For most sites, quarterly updates are enough. Re-run the tool anytime and upload the new version.
04

Does llms.txt actually improve AI visibility?

It makes your content easier for AI systems to understand and cite accurately. It is one of several generative engine optimization (GEO) signals — having an llms.txt does not guarantee citations, but absent one, AI has to guess your structure from less reliable sources.
05

What is the difference between llms.txt and robots.txt?

robots.txt tells search crawlers which pages to index or ignore, using directives (Allow, Disallow). llms.txt tells language models what your site is about, using markdown. Different audiences, different formats, complementary purposes.
06

Is this tool actually free?

Yes. Up to 3 generations per day, no signup. For unlimited generations plus the full GEO workflow — audit, accuracy monitoring, AI action playbooks, citation tracking across ChatGPT, Perplexity, and Google AI — start a 14-day free Prominara trial.
