Odyssey LLMS is the definitive control panel for your website’s AI presence. It generates the critical files used by Large Language Models (like ChatGPT, Claude, and Gemini) to understand and cite your content. For Beginners: Just activate it. A comprehensive and optimised llms.txt file is instantly generated. No configuration is needed. For Power Users: Manage every aspect of your AI strategy. Track bot traffic with built-in analytics, generate JSONL datasets for fine-tuning, and clean up your content with CSS selectors. Concepts Explained: Why do you need this? 1. What is llms.txt? Think of llms.txt as a “Sitemap for AI”. While humans use HTML pages and Search Engines use XML sitemaps, AI agents look for an llms.txt file in your root directory. This file gives them a clean, prioritised list of links to crawl, ensuring they train on your best content and ignore the junk. 2. What is llms-full.txt (Markdown)? This is an optional advanced feature (RAG-Ready). Instead of just providing links, llms-full.txt provides your actual website content converted into clean, lightweight Markdown format. * Why it’s useful: It allows AI agents to ingest your website’s knowledge immediately without needing to visit and scrape every single HTML page. This reduces server load and ensures the AI gets accurate data for “Retrieval Augmented Generation” (RAG). * ⚠️ WARNING regarding Virtual Mode Limits: When using Virtual Mode to generate this file, the item limit for the llms-full.txt file is securely capped at 50 by default. Manually increasing this limit beyond 50 in the ‘Tools’ settings will drastically increase server load and risks causing immediate 500/503 server crashes. Use this feature at your own risk. If you require more than 50 items in your llms-full.txt file, we recommend using Physical Mode instead. 3. What is llms.jsonl (Fine-Tuning)? This file formats your content into prompt-completion pairs (JSON Lines). This is the standard format used to fine-tune models like GPT-4 or Llama 3 on your specific data. New Features in 6.0: JSONL Generator: Create a dataset ready for fine-tuning custom AI models. Content Cleaning: Use CSS selectors (e.g., .sidebar, .comments) to strip unwanted elements from your Markdown and JSONL files. Visual Analytics: Visualise exactly which AI bots (ChatGPT, Claude, Google AI, etc.) are accessing your files with a built-in dashboard widget and charts. WooCommerce Integration: Automatically generates a structured “Products” section including Price, Stock, and SKU. Key Features: Clean Tabbed Interface: Organised into General Rules, Content Sourcing, Analytics, Robots.txt, Security, and Tools. Granular Bot-Specific Rules: Set detailed Allow or Disallow rules for individual AI crawlers (GPTBot, Google-Extended, etc.). “Block All by Default” Mode: Create a secure “whitelist” by blocking all crawlers by default and only allowing the bots you explicitly enable. Settings Import & Export: Perfect for agencies. Easily back up, restore, and migrate your settings between sites with JSON import/export. Advanced Scheduling: Regenerate your file on save, manually, or on a recurring schedule (Hourly, Daily, Weekly, Monthly). Safety Validator: Prevents accidental blocking of all traffic in robots.txt.
