llms.txt Generator
Free tool · by Daniel HaketAI engines are becoming a real traffic source — and llms.txt is the emerging standard that tells them what your site is and which pages matter. Fill in the fields and get a ready-to-upload file.
Upload the file to your site root so it lives at yourdomain.com/llms.txt — next to robots.txt.
What this free tool is great for: a quick, one-off job with no signup — it runs entirely in your browser, so nothing leaves your device and there's nothing to manage.
Its honest limit: it checks or generates one thing in your browser — it won't track rankings over time, monitor changes across many pages, or optimise at scale.
What llms.txt is and why it suddenly matters
llms.txt is a plain-text file that lives at the root of your website — right next to robots.txt — and gives AI systems a clean, curated summary of what your site is and which pages matter. The idea was proposed in late 2024 by Jeremy Howard of Answer.AI, and it spread quickly through documentation platforms and AI-forward companies. The reasoning is simple: when a language model or AI search engine tries to understand your site, it has to wade through navigation, cookie banners, scripts and boilerplate. A concise markdown file that says 'here's who we are, here's what matters, here are the key pages' removes that guesswork. As more people ask ChatGPT, Claude and Perplexity for recommendations instead of scrolling through Google, being easy for AI to understand is turning from a curiosity into a real distribution channel.
The format, in plain terms
An llms.txt file is deliberately simple markdown. It starts with a single H1 heading — your site or project name. Directly under that comes a blockquote: a one-or-two-sentence summary of what the site is, which is the single most important line in the file. After that you can add a short paragraph or two of extra context, and then one or more sections (H2 headings) containing link lists — each entry a page title, its URL, and ideally a short note explaining what a visitor (or an AI) will find there. A conventional final section titled 'Optional' holds secondary links that can be skipped when an AI is working with a small context window. That's the whole standard: name, summary, context, curated links. This generator produces exactly that structure from a handful of fields.
llms.txt is not robots.txt — they do opposite jobs
The two files sit side by side at your site root, but they point in different directions. robots.txt is about access: it tells crawlers which parts of your site they may or may not fetch. llms.txt is about understanding: it assumes the visitor is welcome and hands them the guided tour. One restricts, the other orients. They don't conflict, and a well-run site in 2026 sensibly has both — robots.txt to manage crawling, a sitemap to enumerate URLs for search engines, and llms.txt to give AI systems the short, human-written version of what actually matters. If you think of robots.txt as the fence and the sitemap as the phone book, llms.txt is the welcome leaflet at the front desk.
The honest caveat: adoption is real but uneven
Here's what a lot of breathless articles skip: llms.txt is an emerging convention, not an enforced standard, and support among the big players is mixed. Google has said publicly that its search systems don't use llms.txt, and no major AI vendor formally guarantees they'll fetch it. What is true: a growing number of AI tools, agents and documentation consumers do look for it, the file costs nothing to create, and it carries zero risk — it can't hurt your SEO, slow your site, or confuse regular crawlers. So the honest framing is this: llms.txt is a low-cost, no-downside bet on a direction the web is clearly moving in. Treat it like adding schema markup in 2012 — early, cheap, and sensible — rather than a guaranteed traffic lever someone is selling you.
What to actually put in yours
The biggest mistake is dumping your entire sitemap into the file. llms.txt is curation, not enumeration — the value is precisely that you chose. Lead with the pages that explain and convert: what your product or site does, your best guides or documentation, your pricing, your about page. For each link, write the short note as if answering 'why would an AI send someone here?' — that note is what a model reads to decide whether the page answers a user's question. Keep the summary blockquote tight and factual: what you are, who you're for, what makes you different. Skip legal boilerplate, tag archives and thin pages entirely. A good llms.txt fits comfortably on one screen; if yours scrolls for pages, you've re-created the problem the file exists to solve.
Where AEO and GEO fit in
llms.txt is one piece of a bigger shift people call answer-engine optimisation (AEO) or generative-engine optimisation (GEO): making your content easy for AI systems to understand, trust and cite. The other pieces are things honest SEO has recommended for years — clear headings, direct answers near the top of the page, structured data, real author pages, and content that actually answers the question instead of dancing around it for eight hundred words. AI engines cite sources that give them clean, quotable, verifiable answers. So the sites winning AI citations are mostly the sites that were already doing content properly. llms.txt won't rescue thin content, but on top of solid pages it makes the machine's job — and therefore your citation odds — meaningfully easier.
Where to put it and how to keep it alive
Upload the file to your web root so it resolves at yourdomain.com/llms.txt — the fixed, predictable location is the whole point, exactly like robots.txt. It must be plain text (UTF-8), served like any static file; there's nothing to configure. The quiet failure mode is staleness: a file that still lists pages you deleted or a description of a product you pivoted away from actively misleads the systems you're trying to help. Treat it like your sitemap — regenerate it when your site's structure meaningfully changes, and give it a glance every couple of months. Some sites also publish a companion llms-full.txt containing expanded page content for AI systems that want more depth; that's optional and mainly useful for documentation-heavy sites.
One file is easy — an AI-ready site is the real job — where Rank Math does more
Generating this file takes two minutes with the tool above, and you should absolutely do it. But llms.txt is the smallest piece of being findable in 2026. The heavy lifting is sitewide: titles and descriptions that read well when quoted, schema markup on every page type, clean sitemaps, fast pages, and internal structure that both crawlers and AI systems can follow. That's ongoing, hundreds-of-pages work — exactly what an SEO plugin like Rank Math automates on WordPress, from structured data and sitemaps to per-page optimisation guidance. Use this generator to plant the flag for AI engines; use a proper SEO plugin to make sure that when they arrive, every page underneath actually holds up.
Frequently asked questions
What is llms.txt?
A plain-text markdown file at your site root (yourdomain.com/llms.txt) that gives AI systems a curated summary of your site: name, a one-line description, and your key pages with short notes. It was proposed in late 2024 and is spreading as an AEO/GEO convention.
Does Google use llms.txt?
Google has said its search systems don't use it. A growing set of AI tools and agents do check for it, and the file is zero-risk — so it's best treated as a cheap, sensible bet on where AI search is heading, not a guaranteed ranking lever.
Where do I upload the file?
At the root of your domain, next to robots.txt, so it resolves at yourdomain.com/llms.txt. It's a plain static text file — no server configuration needed.
How is llms.txt different from robots.txt?
robots.txt controls access (what crawlers may fetch); llms.txt aids understanding (what your site is and which pages matter). They complement each other — a well-run site has both, plus an XML sitemap.
