What is LLMs.txt Generator?
The LLMs.txt Generator creates llms.txt files - the proposed Markdown format that gives AI models a curated map of your website. Enter your site name, a short summary, and your key pages, and the tool produces a spec-compliant llms.txt plus an optional expanded llms-full.txt, entirely in your browser.
Key Benefits
- Improve how AI assistants such as ChatGPT, Claude, and Perplexity understand and cite your site
- Follows the llms.txt v2 proposal structure without hand-editing Markdown
- Two outputs from one form: compact index plus expanded full version
- Client-side only, so drafts for private or unpublished sites never leave your machine
Common Use Cases
- •Publishing an AI-friendly index for documentation sites and developer blogs
- •Preparing llms.txt ahead of a product launch so new pages are discoverable from day one
- •Auditing which pages you want generative engines to prioritize over raw crawl data
- •Generating per-project files for open-source repositories hosted on custom domains
How to Generate an llms.txt File
- Enter your site details: Type your site name and a one-line summary. These become the H1 title and blockquote at the top of llms.txt.
- Add your key pages: For each important page, enter a name, URL, and short description. Use the arrows to reorder entries the way you want agents to read them.
- Preview the output: Switch between the llms.txt and llms-full.txt tabs to review the generated Markdown. Toggle blank-line separators to match the spec examples.
- Copy, download, and publish: Copy the output or download it as llms.txt, then upload the file to the root of your domain so it is served at /llms.txt.
Key Features
- Guided form for site name, summary, and unlimited page entries
- Generates both llms.txt and the expanded llms-full.txt from the same data
- Automatic URL normalization so every Markdown link is well-formed
- Optional blank-line separators between sections per the spec examples
- Live tabbed preview with copy and download buttons
- Runs entirely offline in your browser - nothing is uploaded
Frequently Asked Questions
What is an llms.txt file?
llms.txt is a proposed standard: a Markdown file placed at the root of your domain that lists your most important pages with short descriptions, helping AI models like ChatGPT, Claude, and Perplexity understand your site at inference time.
Where should I put the generated file?
Upload it to the root of your website so it is available at https://yourdomain.com/llms.txt. Optionally also publish llms-full.txt alongside it for agents that want expanded content.
Does this tool send my page list anywhere?
No. Everything is generated locally in your browser with JavaScript. Nothing is uploaded, stored, or logged on any server, so you can safely draft files for unpublished sites.
Is llms.txt an official web standard?
Not yet. It is a community proposal that major AI vendors are increasingly adopting. Adding the file is low-effort and harmless, while potentially improving how AI systems represent your content.
