How to Use Your Brainfile

Setup in 3 Steps

  1. Download the template that matches your profession. Open it in any text editor (VS Code, Notion, Google Docs, or even TextEdit).
  2. Customize every bracketed section — replace [YOUR NAME], [YOUR ROLE], and all other [placeholders] with your real information. The more specific you are, the better your AI performs. Delete sections that don't apply to you.
  3. Paste into your AI tool of choice. See the platform-specific instructions below. Update your brainfile monthly as your projects, goals, and preferences evolve.

Platform-Specific Instructions

Claude
ChatGPT
Gemini
Cursor

Claude (Anthropic)

  1. Go to claude.ai and open your project or start a new conversation.
  2. Click Project Knowledge (in Projects) or paste the entire brainfile text at the start of your conversation as your first message with the prefix: "This is my brainfile. Use it as context for all our conversations:"
  3. For Claude Code (CLI): save your brainfile as CLAUDE.md in your project root. Claude Code reads it automatically on every session.

ChatGPT (OpenAI)

  1. Go to Settings → Personalization → Custom Instructions.
  2. Paste the key sections of your brainfile into the "What would you like ChatGPT to know about you?" and "How would you like ChatGPT to respond?" fields. Due to character limits, prioritize the Identity, Communication Preferences, and Domain Knowledge sections.
  3. For longer brainfiles: create a custom GPT with the full brainfile as its instructions, or paste it at the start of important conversations.

Google Gemini

  1. Open Gemini and start a new conversation.
  2. Paste the full brainfile as your first message with the prefix: "This is my professional context file. Use it to personalize all your responses in this conversation:"
  3. For Gemini in Google AI Studio: paste the brainfile into the System Instructions field for persistent context across the session.

Cursor / AI Code Editors

  1. Save your brainfile as .cursorrules (Cursor) or the equivalent config file in your project root.
  2. The AI will automatically read this context for every code generation, review, and chat interaction within that project.
  3. For project-specific context: maintain a separate brainfile per project with project-specific details added to the base template.

Pro Tips for Maximum Impact

Specificity is everything

A brainfile that says "I'm a trader" gives you generic responses. A brainfile that says "I trade momentum setups on S&P 500 components using 21 EMA pullbacks with 2:1 R:R, and I use a scoring system where I only take trades scoring 7+" gives you a personalized trading partner. Every detail you add makes AI exponentially more useful.

Update monthly

Your brainfile is a living document. Update it as projects change, as you learn new preferences, and as your goals evolve. Set a calendar reminder for the first of each month. 15 minutes of updates saves hours of re-explaining context to AI throughout the month.

Delete what doesn't apply

Not every section will be relevant to you. If you don't trade options, delete the options section entirely. If you don't have a board of directors, remove that section. A focused, accurate brainfile beats a long, generic one. AI works better with signal, not noise.

Keep the "Do NOT" section sharp

The "Do NOT" instructions are where the magic happens. Every time AI does something annoying, add it to the "Do NOT" list. Over time, you'll train the AI to avoid your specific pet peeves. This section alone is worth the price of the template.

Frequently Asked Questions

Can I use one brainfile across multiple AI tools?
Yes. Brainfiles are plain markdown text. They work with any AI that accepts custom instructions or system prompts: Claude, ChatGPT, Gemini, Copilot, Cursor, Perplexity, and any future AI tool. That's the point — your context is portable and not locked into any platform.
How long should my brainfile be?
For most people, 300-600 lines is the sweet spot. Long enough to capture meaningful context, short enough that AI can process it effectively. Our Pro templates are 500-600 lines, but you'll likely trim some sections and expand others based on your role. Claude handles very long context well (200K tokens). ChatGPT's custom instructions have character limits, so you may need to prioritize sections there.
What's the difference between a brainfile and a system prompt?
A system prompt is typically short and focused on behavior rules. A brainfile is comprehensive professional context — your identity, expertise, preferences, projects, decision frameworks, and domain knowledge. Think of it as your professional operating manual for AI. A system prompt says "be concise." A brainfile says "I'm a swing trader with 11 years of experience who uses momentum and mean reversion strategies, tracks these specific indicators, makes decisions using this scoring framework, and communicates in this specific way."
Should I include sensitive information?
Use your judgment. Include enough professional context to be useful but avoid sharing passwords, account numbers, SSNs, or highly confidential business information. General financial context (role, strategies, risk parameters) is fine. Specific account balances or client details should be omitted or generalized. When in doubt, ask: "Would I be comfortable if this text were leaked?" If no, don't include it.
Can I share my completed brainfile with my team?
Absolutely. Sharing brainfiles within a team is powerful — it helps AI assist with cross-functional work when it understands everyone's role and context. Many teams create a "team brainfile" that combines individual brainfiles with shared context about the company, processes, and standards. Your Pro license covers personal use, but there's no DRM on the templates.
Do I get updates to the templates?
Yes. As AI tools evolve and we learn new best practices, we update the Pro templates. Your subscription includes access to all updates and new profession templates added during your subscription year. Bookmark this page — template links always point to the latest version.
