Show HN: LLMs Central – Centralized Repository for Llms.txt Files (llmscentral.com)

Show HN: LLMs Central launched a centralized, searchable repository for llms.txt files — site-level policy documents that tell LLMs and AI search engines how to interact with a website. Site owners can submit their llms.txt; the service will fetch and validate the file (format and privacy compliance), add it to the repository, and expose it via a fast API. The platform also provides analytics and insights (tracking how AI platforms access and honor these files), categorization, and dashboard metrics like total domains and valid files to help adoption and discoverability. For the AI/ML community this standardization matters because it creates a single, authoritative source of machine-readable interaction rules that can be integrated into model toolchains, web-browsing agents, and data-collection pipelines. Key technical aspects include automated validation to enforce best practices/privacy constraints, an API for low-latency lookups by LLMs and crawlers, and analytics to monitor compliance and behavior. The service can reduce accidental scraping, help models respect site-level restrictions, and streamline policy-aware data curation — though its usefulness will depend on broad adoption and trust mechanisms to prevent spoofing or misuse.
