llms.txt
also known as: LLM manifest
A plain-text file at a site’s root, written for AI systems and agents rather than human browsers: a short summary of what the product does, the honest facts worth stating up front, and links to the pages that matter most. It is the AI-era counterpart to robots.txt, not a directive, a briefing.
In AI Search API
This site’s own /llms.txt states the product’s honesty contract, its live-vs-roadmap surface list and its base API facts in one dense page, then links out to docs, pricing, the FAQ and this glossary; /llms-full.txt inlines the complete Envelope contract for an agent that wants the whole shape in one fetch, no crawling required. Both are kept consistent with the same _data/surfaces.ts source of truth every rendered page reads, an agent parsing llms.txt should never see a claim the rendered site contradicts. Keeping every link inside it resolvable is treated as part of the honesty contract itself: a manifest written for an "AI said what" company should not itself contain a dead link.
