Free LLMs.txt Generator

llms.txt is an emerging standard that lets websites control how AI crawlers access their content. It tells AI systems like ChatGPT, Claude, and Perplexity which parts of your site they can crawl, which they should avoid, and whether you require attribution when they use your content. As AI search grows, having an llms.txt file helps protect your intellectual property while maintaining visibility.

Enter your website URL and select a template. Our tool auto-crawls your homepage, detects your site type (blog, e-commerce, SaaS, etc.), and generates a properly formatted llms.txt file with appropriate Allow/Disallow rules for major AI crawlers including GPTBot, ClaudeBot, PerplexityBot, and Google-Extended.

We support all major AI crawlers: GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, Google-Extended (Gemini), CCBot (Common Crawl), FacebookBot (Meta), ChatGPT-User, OAI-SearchBot, Applebot, Bingbot, and more. You can toggle each crawler on or off.

robots.txt controls what search engine crawlers can access for indexing in Google, Bing, etc. llms.txt is specifically for AI systems — it controls how AI crawlers use your content for training and generating responses. A site might allow Google to index everything but block AI crawlers from using content for training.

Requiring attribution means AI systems must credit your website when using your content in responses. This is recommended for content creators, publishers, and news sites. E-commerce and SaaS sites may prefer optional attribution. The tool lets you toggle this setting.

Upload the generated file to your website root directory so it is accessible at yourdomain.com/llms.txt. Most CMS platforms (WordPress, Webflow, Shopify) allow file uploads. For custom sites, place the file in your public folder.

Yes. After generating your llms.txt, you can toggle individual crawlers on or off. The preview updates in real-time so you can see exactly which crawlers have access.

Yes. After generating your llms.txt, try our AI Visibility Checker to see how visible your site is to ChatGPT, Perplexity, Claude, and Gemini. Stacc also offers AI search optimization tools.

Without llms.txt, AI crawlers follow your robots.txt rules and their own policies. You have no explicit control over how AI systems use your content. Having llms.txt gives you direct control and signals to AI systems how you want your content handled.

The auto-crawl analyzes your homepage HTML, sitemap XML, and robots.txt to detect site type, content categories, and site sections. It works for most public websites. If your site blocks crawlers or requires JavaScript, you can still use our templates and customize manually.
