robots.txt:

Tells search engine bots which pages they can or cannot crawl
Placed in the website root: /robots.txt
Used for SEO and crawl control
Can block crawling, not guaranteed indexing control
Commonly blocks admin, login, or private pages

llm.txt:

Tells AI / LLM bots (ChatGPT, Claude, etc.) how to use your content
Placed in the website root: /llm.txt
Controls AI training, summarization, or reuse of content
New standard, not all AI bots follow it yet
Focused on content ownership & AI access

Whats your thoughts about their formation?

    In today's developed digital ecosystem, the visibility and control of the website is no longer just hinge on traditional SEO techniques. As AI-powered tools such as ChatGPT, Gemini, Cloud, and Perplexity become major content discovery channels, the nature of the website content control is rapidly changing. Historically, robots.txt has played an important role in guiding the search engine crawlers, enabling webmasters to manage indexing, optimizing the performance of the site and maintaining the SEO. But with the advent of AI-driven generative model crawler management, a new, AI-focused format - llms.txt - is emerging.

    Good explanation. In short, robots.txt controls search engine crawling, while llm.txt is about how AI tools can use website content. robots.txt is well established, and llm.txt is still new, but it may become important as AI usage grows.

    In one sentence, robots.txt tells traditional web crawlers which URLs they can fetch or ignore, while llms.txt provides large language models with a curated, pre-flattened roadmap of your most important content.
