What is llms.txt?
llms.txt is a Markdown file placed at your site's root (yoursite.com/llms.txt) that points AI models to your most important documentation.
What is an llms.txt File and Why Does Your Website Need One?
An llms.txt file is a Markdown document placed at the root of your website (e.g., yoursite.com/llms.txt) that acts as a priority map for AI models and large language models (LLMs). It tells AI tools which pages on your site are most important and worth reading first.
Think of it as the AI equivalent of familiar web standards you already know:
Lists all pages so search engines can find them
Controls which pages search crawlers can access
Signals what matters most to AI models and assistants
Why Your Website Needs an llms.txt File:
- AI Discovery: As AI assistants like ChatGPT, Claude, and Gemini are increasingly used to find and recommend products, having an llms.txt file ensures they can accurately describe your offering.
- Curated Over Comprehensive: AI models perform better with focused, curated information rather than raw data dumps. Your llms.txt tells them exactly where to look.
- Priority Signaling: The ordering of sections and links acts as a priority signal, helping models decide what to read first when context windows are limited.
- Accurate Answers: When users ask AI tools about your product, a well-structured llms.txt helps models give precise, up-to-date answers instead of guessing.
- Future-Proofing: Companies like Anthropic, Vercel, Stripe, and Cloudflare already publish llms.txt files. Adopting this standard now positions your site for the AI-driven web.
LLMS.txt Format and Structure Explained
The llms.txt specification uses standard Markdown with a specific structure. Here is the format that our llms.txt generator follows:
Standard llms.txt Structure
# ProductName > One-sentence description of what the product does ## Section Name - [Link Title](url): Brief descriptive text - [Another Link](url): Explanation of what's inside ## Another Section - [Link Title](url): Description of the content
# H1 HeadingYour product or site name. Must be a single H1 at the top of the file. This identifies your product to AI models.
> BlockquoteA one-sentence value proposition describing what your product does. This gives AI models immediate context about your offering.
## H2 SectionsGroup related documentation under H2 headings. Common sections include Getting Started, Core Concepts, API Reference, Guides, and Resources.
- [Title](url): DescriptionEach link includes a descriptive title, a full URL, and a 1-2 sentence description. Never use vague titles like "API Reference" alone - specify what's inside.
llms.txt vs llms-full.txt: What's the Difference?
Many organizations publish two versions of their llms file. Understanding when to use each helps you serve different AI use cases:
llms.txt (Index)
- Slim, curated list of links
- Low token count for chatbot context
- Best for real-time AI assistants
- Points AI to the right entry points
llms-full.txt (Export)
- Full documentation content inline
- Higher token count for deep context
- Best for IDE integrations and ingestion
- Contains full page content, not just links
Our llms.txt generator creates the index version, which is what most websites should start with. The index file serves real-time chatbots and AI assistants effectively while keeping context windows manageable.
Real-World llms.txt Examples from Top Companies
Leading technology companies have already adopted the llms.txt standard. Here are the patterns they use:
Anthropic (Claude)
Publishes both a slim llms.txt index and a comprehensive llms-full.txt. The index serves real-time chatbots while the full version supports IDE integrations needing deep context.
Vercel
Groups documentation by major product areas (Next.js, Edge Functions, etc.) rather than internal taxonomy. Surfaces quickstarts, core concepts, and high-intent guides consistently.
Stripe
Organizes by resource type (Payments, Checkout, Webhooks). Each section contains a small number of curated links with descriptive text, plus section introductions providing context.
Cloudflare
Covers 20+ products with substantial detail per section, including Getting Started, Configuration, API Reference, and Tutorials for each product area.
Best Practices for Creating an Effective llms.txt File
Follow these best practices when using our llms.txt generator to create a file that AI models can use effectively:
Curate, Don't Dump
AI models perform better with focused, curated information. Include only your most important documentation entry points, not every page on your site.
Use Descriptive Link Text
Never use vague titles like "API Reference" alone. Instead, use "Payments API: Charges and Payment Intents" - specify what's inside so AI models can find the right content.
Lead with Entry Points
Place quickstart guides and orientation docs before deep reference materials. Section ordering acts as a priority signal for AI models.
Organize by User Journey
Structure sections around how users accomplish goals, not your internal documentation taxonomy. Think: Getting Started, Core Concepts, Guides, Reference.
Keep Token Count Low
The llms.txt index file should be concise. AI chatbots have limited context windows. A focused file with 10-30 high-quality links is better than 200 links with no descriptions.
Update Regularly
Keep your llms.txt in sync with your actual documentation. If pages move or new features launch, update the file so AI models always point users to current content.

Frequently Asked Questions About llms.txt
What is an llms.txt file?▼
An llms.txt file is a Markdown document placed at the root of your website (e.g., yoursite.com/llms.txt) that helps AI models discover and understand your most important content. It follows a specific format with a product name (H1), description (blockquote), sections (H2), and curated links with descriptions. It acts as a priority map for AI tools like ChatGPT, Claude, and other LLMs.
Where do I put the llms.txt file on my website?▼
Place your llms.txt file at the root of your domain, so it's accessible at https://yoursite.com/llms.txt. For static sites, put it in your public directory. For Next.js, place it in the public/ folder. For WordPress, upload it to your root web directory.
Is llms.txt the same as robots.txt?▼
No. robots.txt controls which pages search engine crawlers can access, while llms.txt tells AI models which pages are most important to read. They serve complementary purposes - robots.txt is about access control, llms.txt is about priority signaling. You should have both files on your website.
What's the difference between llms.txt and llms-full.txt?▼
llms.txt is a slim index file with curated links and brief descriptions - ideal for real-time AI chatbots with limited context windows. llms-full.txt is a comprehensive export that includes the full content of each linked page inline - ideal for IDE integrations and ingestion pipelines that need deep context. Most websites should start with llms.txt.
Which companies use llms.txt files?▼
Many leading technology companies already publish llms.txt files, including Anthropic, Vercel, Stripe, Cloudflare, Cursor, Windsurf, and Bolt. These companies recognized early that providing structured information to AI models helps their products get recommended accurately in AI conversations.
How many links should I include in my llms.txt?▼
Focus on quality over quantity. Most effective llms.txt files contain 10-30 curated links organized into 3-6 sections. AI models perform better with focused, relevant information than with comprehensive dumps. Include only your most important documentation entry points - quickstarts, core concepts, and high-intent guides.
Does llms.txt help with SEO?▼
While llms.txt doesn't directly affect traditional search engine rankings, it plays an important role in AI visibility and GEO (Generative Engine Optimization). As more users discover products through AI conversations rather than Google searches, having an llms.txt file helps ensure your product gets recommended accurately. It's part of a modern SEO strategy that includes both traditional and AI-focused optimization.
How often should I update my llms.txt file?▼
Update your llms.txt whenever your documentation structure changes significantly - new product launches, major feature releases, or URL changes. There's no need to update it for every minor content change. A good cadence is to review it quarterly or whenever you ship a major update.
Can I use this llms.txt generator for free?▼
Yes, this llms.txt generator is completely free to use. There are no sign-ups, no limits on how many files you can generate, and no watermarks. You can use it as many times as you like for any website. Simply fill in your details, preview the output, and download your llms.txt file.
What format should descriptions use in llms.txt?▼
Descriptions should be 1-2 sentences that explain what the linked page contains. Be specific and actionable. Instead of "API Reference", write "Complete REST API reference with endpoints, parameters, and code examples for all payment operations." This helps AI models select the right page to answer user questions.
