AI Meets API Docs: The Why Behind /llms.txt

ReadMe has introduced support for publishing API documentation as an llms.txt file, a Markdown-formatted page that lists documentation pages and links to help large language models such as ChatGPT and Claude interpret API content. The feature is intended to improve the developer experience by making documentation more accessible through conversational AI tools, potentially helping users learn, troubleshoot, and begin integrating APIs more quickly. Through the ReadMe editor’s AI Settings, teams can enable llms.txt publishing and add an Ask AI menu to guides, allowing users to send a page’s Markdown content to ChatGPT or Claude or copy it for use in another LLM. ReadMe also automatically hosts Markdown versions of guides through URLs ending in .md, while positioning these AI capabilities as an extension of its ongoing focus on developer-centered API documentation and onboarding.
