What this tool does

llms.txt is an emerging standard for declaring to AI agents (ChatGPT, Claude, Perplexity, Google AI Overviews) which URLs on your site contain the most important content. This generator handles the boring parts: finding your sitemap, parsing it, fetching titles, and grouping URLs into a clean structure.

1. Sitemap auto-discovery

We probe 7 common sitemap locations (including sitemap_index.xml for WordPress + Yoast) and parse the Sitemap: directive in robots.txt.

2. Smart URL grouping

URLs are automatically grouped by path pattern (services, tools, blog, case studies). Edit groups inline; reorganize freely.

3. Title autofill

We fetch the first 60 pages in parallel through our proxy and extract <title> tags so every line has a real description.

4. Live editable preview

Both llms.txt and a starter llms-full.txt scaffold render live as you edit. Copy or download when ready.

Edit your llms.txt
