What is llms.txt and why do I need one?+
llms.txt is a Markdown file at your domain root (yourdomain.com/llms.txt) that tells AI models what your site is about and which pages matter most. As people increasingly ask ChatGPT, Claude, Perplexity and Google AI Overviews instead of searching, an llms.txt gives those models a clean, curated map of your content so they understand and cite it accurately.
How do I create an llms.txt file for free?+
Paste your domain into this generator. It discovers your sitemap, reads your real page titles and descriptions, and builds a valid llms.txt grouped into sections. Edit the summary and links, then copy or download the file and upload it to your site root. No signup and no coding required.
What is the difference between llms.txt and llms-full.txt?+
llms.txt is the concise index, your site name (H1), a one-line summary (blockquote), and grouped links with short descriptions. llms-full.txt is a longer companion that inlines more context for models that want deeper detail. This tool generates both; publishing both serves lightweight and more capable AI models alike.
How is llms.txt different from robots.txt and sitemap.xml?+
robots.txt controls which crawlers may access your site, sitemap.xml lists every URL for search engines, and llms.txt is a curated, human-readable summary written specifically for AI language models. They complement each other: this tool can also generate a robots.txt snippet that allows or blocks specific AI crawlers.
Where do I put the llms.txt file?+
Upload it to the root of your domain so it's reachable at https://yourdomain.com/llms.txt (and llms-full.txt at https://yourdomain.com/llms-full.txt). That's the same place your robots.txt lives. The tool includes a short install guide for common setups.
Does llms.txt help my SEO and AI search visibility?+
It's an emerging standard rather than a confirmed ranking factor, but it makes your most important content easy for AI answer engines to parse, which is central to Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO). Clear structure and accurate summaries reduce the chance an AI misrepresents your site.
Which AI crawlers can I allow or block?+
The generator produces a robots.txt policy snippet for the major AI user-agents, including GPTBot and OAI-SearchBot (OpenAI/ChatGPT), ClaudeBot (Anthropic), PerplexityBot, Google-Extended (Gemini/AI Overviews), Applebot-Extended, CCBot and Bytespider. You choose which to allow so your content appears in the assistants you want.
Do I need a sitemap to use this tool?+
No. If your site has a sitemap the tool auto-fills everything from it, but you can also add pages manually, paste a title and short description for each, and the generator will build a valid llms.txt from those instead.
Is my data private?+
The crawl reads your public sitemap and page metadata to pre-fill the editor. After that, every edit and both output files are assembled entirely in your browser, nothing you type is uploaded or stored.
Is the generated llms.txt valid?+
Yes. It follows the llmstxt.org Markdown format, an H1 with your site name, a blockquote summary, and '##' sections of Markdown links with descriptions, and the built-in validator warns you if the H1, summary, sections or links are missing or malformed before you publish.
Can I generate llms.txt from just my sitemap.xml URL?+
Yes. Paste a direct sitemap.xml (or sitemap-index) URL and the tool parses it, follows child sitemaps, reads page metadata and turns the whole thing into a structured llms.txt, effectively a sitemap-to-llms.txt converter.
