Free llms.txt Generator
This free tool scans your sitemap and internal pages, pulls the titles and meta descriptions you already published, and builds a ready-to-use llms.txt file in seconds. No sign-up, no AI-guessed descriptions, no hidden fee to download: enter your URL, review the live preview, then copy or download your file.
Your llms.txt
Enter your website address and click Generate: your file will appear here, ready to review and download.
How Does This llms.txt Generator Work?
Enter Your URL or Sitemap
Paste your homepage URL or your sitemap.xml address into the field above. The generator reads your public site structure without asking for a login, an API key, or any access token, and nothing is installed on your server at this stage.
We Crawl Your Site and Extract Real Data
The tool crawls your public pages and extracts the titles and meta descriptions you already published, exactly as they appear in your HTML. Nothing is rewritten or invented: if a page has no meta description, the field stays empty rather than being filled with an AI guess, so what ends up in your file matches what a real visitor would find on the page.
Preview, Edit, Then Copy or Download
A live preview shows the generated file before you commit to anything. You can edit any line directly in the browser, rename a section, or remove a page you don’t want listed, then copy the text or download the .txt file, with no paywall on either step and no limit on how many times you regenerate it.
What Is an llms.txt File?
An llms.txt file is a plain Markdown document placed at the root of your domain (yourdomain.com/llms.txt) that gives AI language models a clean, structured summary of your site: what it does, and which pages matter most. It follows a format proposed by Jeremy Howard in September 2024, now documented at llmstxt.org, and it is read by AI crawlers such as GPTBot, ClaudeBot, and PerplexityBot, rather than by traditional search engine bots.
Structurally, the file opens with an H1 title and a short blockquote summary, followed by H2 sections that link to your most important pages with a one-line description each. Some sites also publish a companion llms-full.txt file, which expands the same structure into full page content rather than links alone.
The format exists because AI models struggle to parse a typical web page: navigation menus, ads, cookie banners, and boilerplate HTML add noise that wastes the limited context window a model can process at once. An llms.txt file strips all of that away and hands the model a short, curated list of what actually matters on your site, in the order you choose.
Example of a generated llms.txt file (H1 title, summary, and linked sections):
# Acme Outdoor > Acme Outdoor designs and sells durable hiking gear, with free repairs for life. ## Products - [Trail backpacks](https://acme-outdoor.com/products/trail-backpacks): 20 to 60 liter packs tested on long-distance trails. - [Rain jackets](https://acme-outdoor.com/products/rain-jackets): Waterproof shells rated for alpine conditions.
llms.txt vs. robots.txt vs. sitemap.xml: What’s the Difference?
These three files serve different readers and different purposes, and confusing them is a common mistake that can waste time on the wrong fix. The table below compares what each file does, who actually reads it, and when you would use it.
| File | What It Does | Who Reads It |
|---|---|---|
| llms.txt | Summarizes your site and links to key pages for AI language models to read | AI crawlers and assistants such as ChatGPT, Claude, Perplexity, and Gemini |
| robots.txt | Tells crawlers which pages they are allowed or forbidden to crawl | All bots, including traditional search engine crawlers and AI crawlers |
| sitemap.xml | Lists every indexable URL on your site so it can be discovered and crawled | Search engines such as Google and Bing, for indexing purposes |
Does llms.txt Actually Help You Get Cited by AI?
Adding an llms.txt file is low-risk and low-cost, but it is not the reason your content gets cited by an AI assistant: the actual text on your pages is. A June 2026 industry study of 137,210 domains found that only 28% of sites publish an llms.txt file, and that 97% of the files published received zero requests from any AI crawler during the month studied.
Even among the small share of files that do get requested, most of that traffic is not coming from named AI tools. The same June 2026 study found that only 19.5% of the already-rare requests came from identified AI tools, meaning most llms.txt fetches are unattributed or automated traffic rather than a clear signal of AI adoption.
None of this makes the file worthless, it simply puts the stakes in perspective. AI usage keeps growing regardless: OpenAI reported 900 million weekly active ChatGPT users on February 27, 2026, and Google announced that AI Mode had passed 1 billion monthly active users one year after launch, in its Google I/O 2026 announcement on May 19, 2026. At that scale, being readable and citable by AI models is worth the near-zero cost of publishing the file, even if llms.txt alone is not the deciding factor.
The signals that do tend to matter are structural: a direct answer in the opening sentence, a dated source next to any number, and clear headings that separate one sub-topic from the next. Generative Engine Optimization (GEO) relies on these same principles: llms.txt can point a crawler toward the right pages faster, but it cannot turn a vague, unsourced page into one worth quoting.
How Do I Install My llms.txt File?
Once you’ve downloaded your file, upload it to the root of your domain so it lives at yourdomain.com/llms.txt, exactly like robots.txt and sitemap.xml. There is no single official method: how you get a file onto your domain root depends entirely on where your site is hosted.
| Platform | Where to Put the File |
|---|---|
| WordPress | Upload the file to your site’s root folder via FTP or your host’s file manager, or use a plugin that allows root-level uploads. |
| Shopify | Add a templates/llms.txt.liquid file in your theme code (Online Store > Edit code), the same mechanism Shopify uses for robots.txt, or use a dedicated app if you’d rather not touch the theme. |
| Next.js / React | Place the file in your public folder; most frameworks serve anything inside public/ directly from the domain root at build time. |
| Webflow | Upload the file directly in Site Settings: Webflow has a dedicated llms.txt upload field that publishes it to your domain root automatically once you publish the site, no custom code needed. |
| cPanel / shared hosting | Log into File Manager, open the public_html folder, and upload llms.txt directly next to your existing robots.txt file. |
| Netlify / Vercel | Drop the file into your project’s public or static folder before deploying; both platforms publish it automatically at the domain root. |
Frequently Asked Questions
Is llms.txt an Official Web Standard?
No, llms.txt is not an official web standard recognized by a body such as the W3C. It’s a proposed convention introduced by Jeremy Howard in September 2024 and documented at llmstxt.org. Some AI companies read files that follow this format, but none are required to, and no governing organization enforces or ratifies it.
Do Google, Bing, and Other Search Engines Read llms.txt Files?
Traditional search engines rely on sitemap.xml and robots.txt to crawl and index your pages, not on llms.txt. The format was designed specifically for AI language models and assistants, like the crawlers behind ChatGPT, Claude, and Perplexity, not for classic web search indexing. Publishing the file won’t directly change your rankings on Google or Bing.
What’s the Difference Between llms.txt and llms-full.txt?
llms.txt is a short index: an H1 title, a summary, and links to your key pages with a one-line description each. llms-full.txt is a companion file that expands those same sections into the actual page content, so an AI model can read everything in one file instead of following each link separately. Not every site needs both; llms.txt alone covers most use cases.
How Often Should I Update My llms.txt File?
Update your llms.txt file whenever you publish a new page you want AI models to know about, or whenever a title or meta description changes on an existing page. For most sites, checking the file every time you publish new content, or at least once a quarter, keeps it accurate without turning it into a maintenance burden.
Is This llms.txt Generator Really Free, and Do You Store My Website Data?
Yes, generating and downloading your file is completely free, from the first scan to the final download, with no account, no payment details, and no hidden step in between. The tool only reads the public pages and metadata already published on your site to build the file, and you can regenerate or edit it as many times as you like.
Can I Edit the Generated File Before Downloading It?
Yes. Before you download or copy anything, the tool shows a live, editable preview of your llms.txt file. You can rename a section, rewrite a description, remove a page you don’t want listed, or reorder links, then copy the final text or download it as a ready-to-use .txt file whenever you’re ready, with no time limit on the preview.
One Free Tool, One Bigger Question
Want AI to Actually Cite Your Content?
Publishing an llms.txt file costs nothing and takes a few seconds, but it won’t make an AI model quote your page if the content itself isn’t structured to be quoted. What actually earns citations is clear, well-sourced writing built around the questions people, and AI models, are asking. MentionLab writes and structures that content for you, calibrated against what already ranks, then tracks when ChatGPT, Claude, and Perplexity actually mention your site, not just whether a crawler stopped by.
