llms.txt Generator

What is llms.txt?

llms.txt is a simple Markdown file you place at the root of your domain. It gives AI assistants a curated, easy-to-read map of your most important pages — your products, docs, guides and key landing pages — without forcing them to crawl noisy HTML.

Think of it as a friendly index for large language models. A clear llms.txt helps AI engines understand what your site is about and which pages to cite, improving how your brand shows up in AI answers.

What llms.txt is — and why it exists

llms.txt is a proposed open standard that gives AI assistants and large language models a single, curated map of the content on your site that matters most. It lives as a plain markdown file at the root of your domain — for example, https://yourdomain.com/llms.txt — and it lists your most important pages with short, human-written descriptions. The idea is simple: instead of forcing an AI crawler to guess which of your thousands of URLs are worth reading, you hand it a clean, prioritized index it can ingest in one request.

The format is deliberately minimal markdown. It opens with a single H1 (# Your brand) that names the project or company, an optional blockquote (> a one-line summary) that captures what you do, then a series of H2 sections (## Docs, ## Products, ## Guides) whose bullet points are markdown links to the underlying pages. Each link can carry a short note explaining what the page covers. Because it is just markdown, an LLM can parse it instantly and the descriptions add the context a raw URL list never could.

llms.txt was proposed because the web was built for browsers and search engines, not for the limited context windows of language models. A modern site ships heavy HTML wrapped in navigation, scripts, cookie banners and ads — noise that wastes the tokens an AI has to spend reading you. llms.txt strips that away: it points the model at the signal, in a format it already understands, so it can find, understand and cite your key content far more reliably than by crawling raw HTML.

There is a companion file, llms-full.txt, that goes one step further by including the actual full text of your key pages in markdown, not just links to them. /llms.txt is the curated table of contents; /llms-full.txt is the whole book inlined. Together they let an AI either pull a quick map of your site or read your core content directly without making a single extra request — which is exactly what you want when an assistant is deciding whether to recommend you.

llms.txt glossary

The vocabulary of making your site readable to AI, in plain language.

llms.txt

A proposed standard: a markdown file at your site root listing your most important pages with descriptions, so AI assistants can find and understand your key content quickly.

llms-full.txt

A companion file that inlines the full markdown text of your key pages, not just links — letting an AI read your core content in a single request without crawling each page.

markdown

A lightweight plain-text format using # for headings, > for quotes and [text](url) for links. It is the format llms.txt uses because language models parse it cleanly.

sitemap.xml

An XML file listing every URL on your site for search-engine crawlers. It aims for completeness for indexing, whereas llms.txt is a curated, human-readable subset for AI comprehension.

robots.txt

A root file that tells crawlers which paths they may or may not fetch. It governs access; llms.txt governs understanding. The two are complementary, not interchangeable.

AI crawler

A bot such as GPTBot, ClaudeBot or PerplexityBot that fetches your pages so an AI model can read, index and potentially cite them. llms.txt is built for these crawlers to consume.

context window

The fixed amount of text an LLM can hold in working memory at once. llms.txt exists partly to use that budget efficiently by feeding the model clean signal instead of noisy HTML.

RAG (Retrieval-Augmented Generation)

When an AI fetches live documents and grounds its answer in them rather than training data alone. A well-structured llms.txt makes your content easier to retrieve and quote in this flow.

root path

The top level of your domain (the / directory). Standard discovery files like robots.txt, sitemap.xml and llms.txt all live here so crawlers can find them at a predictable address.

entity

The distinct thing an AI identifies you as — your brand, product or company. A clear title and summary in llms.txt help a model resolve your entity before it reads anything else.
