# Free LLMs.txt Generator — Foreground Digital > Generate a valid llms.txt file for AI search engines. Built on the Answer.AI standard — helps ChatGPT, Claude, and Perplexity cite your site cleanly. Source: https://foreground.agency/tools/llms-txt-generator/ --- [Free tools](https://foreground.agency/tools) / LLMs.txt File Generator # llms.txt — robots.txtfor the AI era. New standard. Different purpose. Where robots.txt tells crawlers what not to read, llms.txt tells language models what to read — and gives them clean, structured links to do it. How to write llms.txt ## What it is, and why it might be the next sitemap.xml. 01 — The origin ### A proposed standard from Answer.AI. Proposed by Jeremy Howard (Answer.AI, fast.ai) in September 2024 at llmstxt.org. The goal: give large language models a single, curated entry point that explains your site without forcing them to render JavaScript, parse navigation, or guess at hierarchy. It is not a W3C standard (yet) — it's a community convention being adopted by docs platforms (Mintlify, Vercel, Cloudflare, Anthropic, Stripe). 02 — Where it lives ### Two files at your domain root. - ·/llms.txt — the curated index. A short markdown file with site name, one-line description, and links to your most important pages with one-sentence summaries. - ·/llms-full.txt (optional) — the full body. Concatenated markdown of every page you want LLMs to ingest. Big file, but cheap for a model to consume. This generator builds the first one. The second is usually generated by your CMS or a build script (we do these for clients). 03 — The format ### Markdown, with strict structure. # Site Name > One-sentence summary. Tells the model in plain English what this site is. A free-form paragraph or two of additional detail. Mention what's in scope, what's out of scope, the audience. ## Docs - [Quick start](https://example.com/docs/quickstart): How to set up in five minutes. - [API reference](https://example.com/docs/api): Full endpoint docs with examples. ## Blog - [Latest post title](https://example.com/blog/slug): One-line summary of what it covers. ## Optional - [Pricing](https://example.com/pricing): Plans and limits. Required: the H1 site name, the > blockquote summary. Recommended: H2 sections grouping links by intent. Each link is a markdown link followed by : description. Sections named "Optional" tell the model it can skip them under context pressure. 04 — Why it matters ### AI-native search is the new top-of-funnel. ChatGPT search, Perplexity, Claude with web access, Gemini Deep Research — these tools are increasingly how people find vendors, products, and answers. They don't render JS. They struggle with deep navigation. They cite cleanly when given clean entry points. A good llms.txt is the difference between "we appeared in 3% of relevant AI answers" and "we appeared in 40%." It's also forward-defensive: if the standard takes off, sites that adopted early get the link-equity head-start. If it doesn't, you've lost an afternoon writing a clean site index — which has secondary uses anyway (newsletter, sales onboarding, internal docs). 05 — The rules ### Five things to do, three to avoid. Do - ·Link to canonical URLs. Absolute, not relative. - ·Use HTTPS. Always. - ·Group by intent (Docs, Blog, About, Pricing). - ·Write descriptions for humans first — models are trained on human prose. - ·Re-generate when your site's IA changes. Don't - ·List every URL on your site — that's what the sitemap is for. - ·Stuff keywords into descriptions. Models notice. - ·Forget the H1 + blockquote — without them, parsers may reject the file.
