llms.txt Generator
Automatically generate an llms.txt file for your website. This tool crawls your site, analyzes its structure, and creates a properly formatted llms.txt file following the llmstxt.org specification—making your content accessible to AI systems.
What is llms.txt?
llms.txt is a special text file (written in Markdown format) that you place at the root of your website (e.g. yourwebsite.com/llms.txt). It provides a curated, LLM-friendly summary of your site's important content.
First proposed by technologist Jeremy Howard in 2024, llms.txt gives AI models a shortcut: instead of crawling and parsing your entire site, an LLM can read the llms.txt file to quickly learn the key information and find direct links to detailed content.
Why Does llms.txt Matter?
LLMs have different needs than traditional search engine crawlers. They excel at understanding text and answering questions, but they struggle with the volume and format of modern websites.
Handles Context Limits
AI models can only "read" a certain amount of text at a time. An llms.txt condenses your site's crucial info into one place, making it feasible for an AI to load it into context.
Simplifies Complex Pages
llms.txt is pure plain text in Markdown, which is very easy for LLMs to consume. By providing information in a simplified format, you reduce the chance of AI misinterpreting content.
Curates What's Important
Not every page on your site is equally useful for answering user questions. In llms.txt, you choose the most important pages to highlight, guiding AI to focus on relevant content.
Improves AI Answer Accuracy
By giving AI a curated source, you increase the chances that when someone asks an LLM about your site, it will pull correct information. Companies like Vercel report 10% of signups from ChatGPT after optimizing for AI.
How Does llms.txt Work?
An llms.txt file is simply a text file formatted in Markdown, following a specific structure. Because it's Markdown, it's both human-readable and machine-readable.
H1 Title (Required)
The file starts with an H1 heading (one # in Markdown) which is the name of your website or project. This is the only required part.
Short Description (Blockquote)
A brief summary of your site enclosed in a Markdown blockquote (>). This should be 1-3 sentences giving an "elevator pitch".
Detailed Notes
One or more regular paragraphs or bullet lists with additional details about your project.
Section Headings (H2)
Create sections with H2 headings (##), each followed by a bullet list of links. Group related content like "Documentation", "Products", "API", etc.
"Optional" Section
A special section for secondary content. AI agents might skip these if they have limited capacity.

As of early 2026, llms.txt is still an emerging practice, and support from the major AI players is limited but growing.
| Status | Details |
|---|---|
| Not Official Yet | None of the major LLM providers (OpenAI, Google, Anthropic) have formally announced support. Google's John Mueller stated "no AI system currently uses llms.txt" as of late 2025. |
| Early Signs | Google included llms.txt in their experimental Agents to Agents (A2A) protocol. Anthropic published an llms.txt on their own website and requested docs platforms to implement it. |
| Active Crawling | Data from Profound shows that models from Microsoft, OpenAI, and others have been actively crawling and indexing llms.txt files on the web, suggesting experimental usage. |
| Early Adoption | Around 950+ websites have adopted llms.txt as of mid-2025, primarily tech-savvy companies like Hugging Face, Vercel, Zapier, and Cal.com. |
