llms.txt for AI-Readable Site Indexes

llms.txt is a plain-text index that helps AI crawlers discover important URLs and understand site purpose. Primenza audits llms.txt coverage, generates recommendations, and can deploy files when your workflow allows.

What llms.txt is

llms.txt is a machine-readable file, typically at /llms.txt, that summarizes what a site offers and which URLs matter most for AI retrieval. It complements robots.txt and structured data — it does not replace them.

Primenza llms.txt workflow

From your domain dashboard: analyze current llms.txt if present, generate an updated file based on crawl priorities, review changes, and deploy manually or via Smart Agent.

Primenza public llms.txt

Primenza publishes its own llms.txt at https://primenza.com/llms.txt as a factual index of product modules, public pages, and key concepts.

Limitations

llms.txt is one signal among many. Publishing llms.txt does not guarantee inclusion in any AI index or citation.
