llms.txt Generator

Generate an llms.txt file that helps AI engines like ChatGPT and Perplexity understand your site — a simple GEO step.

100% Browser-Based • Local Processing

1 · Your site Site or project name required Becomes the # heading, the one part the format actually requires. One-line summary Becomes the > blockquote directly under the title. Longer description optional Plain paragraphs only — headings here would break the file's structure.

2 · Key sections

A section titled Optional is special: it marks pages a model may skip when it is short on context. It is always written last.

llms.txt

An emerging proposal, not a standard. llms.txt comes from llmstxt.org and is not backed by the search or AI companies; support across engines is partial and changing. It is cheap and harmless to publish — but crawlable, clearly written pages still do far more for how AI represents you.

Output

Upload as llms.txt at the root of your domain, so it answers at https://yoursite.com/llms.txt — the same placement as robots.txt. Keep it a curated map of your best pages, not a dump of every URL.

Overview

What is a llms.txt Generator?

An llms.txt Generator creates an /llms.txt file — a Markdown summary of your site for AI engines. It gives large language models a concise, curated overview of what your site is and links to your key pages, helping tools like ChatGPT and Perplexity understand and represent your content. Enter your site details and copy or download the file.

llms.txt is an emerging convention — a Markdown file at your site's root that gives AI engines a clean, human-curated summary of your site and its most important pages. It's the AI-era cousin of robots.txt and sitemap.xml: a low-effort way to help large language models understand what you offer.

This generator builds a spec-style llms.txt from a short form. It runs entirely in your browser, and the file is yours to copy or download and place at your root.

Details

What llms.txt is — and how it fits GEO

The llms.txt format is a simple Markdown file: an H1 with your site or project name, a short blockquote summary, an optional longer description, and one or more sections of links (each a name, URL, and short note) pointing AI engines to your most important pages — docs, key articles, product pages. The idea, proposed at llmstxt.org, is to give large language models a concise, authoritative map of your site so they can understand and represent it accurately, rather than guessing from scattered crawling. This is part of GEO (Generative Engine Optimization) — optimising for AI answer engines — alongside clear content, structured data, and an accessible site. Two honest caveats: llms.txt is an emerging proposal, not an official, universally adopted standard, and not every AI engine reads it yet, so think of it as a cheap, sensible step that may help rather than a guaranteed lever. It pairs well with making your actual pages crawlable and clearly written, which matters more. The generator produces clean Markdown with absolute URLs; everything runs locally in your browser. To control which AI crawlers can access your site, use the AI Crawler Control generator.

Frequently Asked Questions

What is llms.txt?

llms.txt is a proposed Markdown file placed at your site's root (yoursite.com/llms.txt) that gives AI engines a concise, curated summary of your site and links to its key pages. It's designed to help large language models like ChatGPT and Perplexity understand what your site is about and represent it accurately.

Where do I put the llms.txt file?

At the root of your domain, reachable at https://yoursite.com/llms.txt, served as plain text/Markdown — the same location pattern as robots.txt. Use absolute URLs for the links inside it. Some sites also publish an expanded llms-full.txt with more detail, but the root llms.txt is the core file.

Is llms.txt an official standard?

No — it's an emerging community proposal (from llmstxt.org), not an official standard backed by the search or AI companies, and adoption is still growing. Treat it as a low-cost, sensible step that may help AI engines understand your site, rather than a guaranteed or required ranking factor.

Do AI engines actually read llms.txt?

Support is partial and evolving — some AI tools and crawlers reference it, others don't yet. Because it's cheap to create and does no harm, it's a reasonable thing to publish as part of a GEO strategy, while recognising that making your real pages crawlable, clear, and well-structured does more for AI visibility today.

How is llms.txt different from robots.txt and sitemap.xml?

robots.txt tells crawlers what they may crawl; sitemap.xml lists your URLs for discovery; llms.txt gives AI engines a human-curated summary and pointers to your most important content. They serve different audiences — robots.txt and sitemap.xml are for search crawlers, llms.txt is aimed at large language models.

What should I include in llms.txt?

Your site name, a one-sentence summary of what it is, a short description, and a curated list of your most important pages — documentation, key articles, main product or category pages — each with a short note on what it covers. Keep it concise and accurate; it's a map of your best content, not a dump of every URL.

Is it free, and do I need to sign up?

Yes, it's completely free with no account, no trial, and no limit on how many times you use it. Unlike most SEO suites, there's no login wall — it runs entirely in your browser, so you just open the page and use it.

Is my data private?

Yes. Everything is processed in your browser — whatever you type or paste is never sent to a server. Nothing is stored once you close the tab, so your URLs, content, and site details stay on your own device. That client-side approach is the core difference from cloud SEO tools.

Does it work on mobile?

Yes. It runs in your phone's browser with nothing to install, so you can generate or check markup on Android or iOS. The layout adapts to small screens, though pasting longer code is easier on a desktop.

Does it work offline?

Once the page has loaded, the work runs entirely on your device, so it keeps working without a connection. You only need to be online to open the page the first time — which is also why nothing you enter is uploaded.

Can I copy the output?

Yes. You can copy the generated code or results to your clipboard with one click, ready to paste straight into your site's HTML, CMS, or files. Because everything runs locally, copying is instant with no upload step.

Will this directly improve my rankings or get me into AI answers?

It produces correct, standards-compliant markup that helps search engines and AI engines (Google, AI Overviews, ChatGPT, Perplexity) understand your page clearly — which is a prerequisite for ranking and being cited. But it doesn't directly change rankings or guarantee a rich result or AI citation; those are decided by the engines based on your overall content and authority.
