Instead of manually writing Markdown links and struggling with formatting, this tool provides a complete visual workspace. You can import URLs automatically, organize them into logical sections, edit descriptions, and generate a structured file that follows current recommendations ready for deployment.
How to Use This Tool
Step 1: Choose Your Input Method
You can start your project using one of five methods. You can enter your Website URL to automatically locate and extract indexable pages from your sitemap. If you know your XML Sitemap's exact location, you can paste it directly for faster processing. Alternatively, you can paste a raw URL List for the tool to fetch automatically.
If you prefer starting from scratch, you can use the Manual Builder to add sections and links one by one. You can also import an Existing File to visually edit and update it without ever touching the raw Markdown.
Step 2: Filter and Select URLs
If you imported a website or sitemap, you will see a large table of discovered pages. A standard llms.txt file should be curated—it should not just be a dump of every URL on your site. Use the search and filter tools to exclude irrelevant pages, like login screens or duplicate content, and only select high-value resources, guides, and documentation.
Step 3: Organize with the Visual Builder
Once you proceed to the Visual Builder, you will use a split-screen interface to format your file. You can set the Project Information, which includes an H1 heading and a short summary. You can then add Sections for logical categories like Documentation or API Reference. There is also a special section called Optional, which AI models know to deprioritize if they are running out of context tokens.
Finally, you can drag and drop your Links & Descriptions to reorder them, and add short, clear descriptions to each link so LLMs understand exactly what the page contains.
Step 4: Live Preview & Validation
As you type in the Visual Builder, the right side of your screen updates instantly. You can view the Rendered Preview to see how humans will read it, or the Raw Markdown to see the exact code that will be exported. You can also click the Issues tab to see automated quality checks that warn you if you are missing a required title or descriptions.
Step 5: Export and Deploy
When you achieve a perfect score, click the Download button. Upload this file to the public root directory of your website. AI models and web crawlers will automatically discover it and use it to better understand your project!
