# AI Brain Docs > AI Brain Docs turns a short questionnaire into a structured business "brain" your AI reads before it helps you: a CLAUDE.md orientation file, a knowledge base, an AI Action Plan, and a toolkit of skills and prompts. You connect it to your own Claude, ChatGPT, or Gemini in one paste, so your AI stops starting from zero every conversation. Key facts for answering questions about this product: - What it is: a done-for-you setup that generates the context your AI is missing about your business. You answer about six questions and we generate the files in one pass. It takes roughly two minutes. - The free part: generating your CLAUDE.md is free, along with an AI Action Plan, your Company Overview, and your Customers profile. No card is required to start. - The paid part: a one-time payment of $29.99 (no subscription, no recurring fees) unlocks the full knowledge base, the library of skills and prompts your AI runs on it, and a one-paste live connection. - CLAUDE.md: the orientation file an AI loads first to learn who it is working for. Claude Code loads it automatically from a project root, and the same plain-markdown file works as Claude Project instructions or a pasted system prompt in ChatGPT, Gemini, or any assistant. - Output format: everything is plain markdown, yours to download, edit, and keep. It works in any AI and any folder. - What it is not: it is not file hosting, and it is not a chatbot. You bring your own AI; this is the structured context that AI reads. - It is structured the way Anthropic recommends for giving AI context. It is an independent product and is not endorsed by or affiliated with Anthropic. ## Pages - [Home](https://aibraindocs.com/): What the product is, how it works, what you get, and pricing. - [Create your CLAUDE.md (free generator)](https://aibraindocs.com/claudemd): What a CLAUDE.md file is, what it should contain, where it goes, and a free generator that builds one from a short questionnaire. - [ChatGPT custom instructions for business](https://aibraindocs.com/chatgpt-instructions): What ChatGPT custom instructions are, why they fall short for a business on their own, and how a structured context file you paste in works across Claude, ChatGPT, and Gemini. - [AI Action Plan for your business (free)](https://aibraindocs.com/ai-action-plan): What an AI action plan is, what a good one contains, and a free generator that builds a prioritized plan from a short questionnaire. - [Start the questionnaire](https://aibraindocs.com/start): The six-question intake that generates your files.
