What is llms.txt?

llms.txt (and the more comprehensive llms-full.txt) is an emerging convention — analogous to robots.txt — that hosts a Markdown summary of a site's most important content, positioning, and citations for AI crawlers. It improves extraction accuracy and reduces the risk of LLMs mis-attributing or hallucinating about your brand. Crackle PR publishes an llms.txt and llms-full.txt on cracklepr.com as public proof of the discipline — the same manifest we build for clients so LLMs cite the right pages instead of hallucinating.
