I keep meeting smart people who treat AI like a vending machine. They type a quick request, get a generic answer, and walk away thinking the tool is overrated. The problem isn’t the tool. It’s that the AI has no idea who they are, how they think, or what they actually want.
That’s why a step-by-step guide from an AI professional on LinkedIn stopped me in my tracks. The creator laid out a full system for copying your entire brain into Claude, so the model stops guessing and starts sounding like the real you. I was genuinely impressed by how practical it is, so I broke the whole thing down below.
The big idea from the original poster is simple: you build three personal files once, then every AI you touch reads them and instantly knows your voice, your goals, and your taste. Here’s how the expert walks through it.
🧠 The 11-step build
Each step has a clear job. I added the reasoning behind it so you know why it matters, not just what to click.
- Download the Claude desktop app, set the top Opus model as your default, and turn on Extended Thinking so it reasons before it answers.
- Open Cowork mode (the tab between ‘chat’ and ‘code’) and create a folder called “Brain” inside. This is where your identity will live.
- Install a free voice-to-text tool like Wispr Flow. The author argues that speaking is faster and more honest than typing, because typing makes you edit yourself.
- Run a 100-question “taste interview” with the AI: 100 questions across 7 categories. Push past every vague answer and get specific.
- Compress that giant brain dump into a clean summary and save it as an about-me.md file.
- Write an anti-ai-writing-style.md file listing every word and habit you refuse to see, like banning “delve” and killing the “it’s not X, it’s Y” pattern.
- Write a my-company.md file with your goals, your focus, and your hard no’s. The creator calls this your north star file.
- Test it all in a fresh blank chat with a prompt only you would write. If the output sounds like you, you’re on the right track.
- Drop all three files into your “Brain” folder so Claude reads them on every single turn.
- Port the same files into ChatGPT, Grok, and Gemini, so you get the same brain in every AI.
- Edit the files forever. Install Obsidian (free), open your folder as a vault, and update as you grow.
🎙️ Why voice beats typing
This was my favorite insight from the post. The expert points out that when you type, you polish and hedge. When you talk, the truth slips out. Dictating your context captures how you actually think, including the messy, opinionated parts that make your voice yours. So instead of writing careful answers to those 100 questions, you just talk and let the tool transcribe.
✍️ The anti-style file is the secret weapon
Most people skip this part, and the creator says that’s exactly why their AI output reads like every other AI on the planet. Your anti-ai-writing-style.md file is a list of bans. Words you hate. Phrases that aren’t you. The fake-deep contrast patterns. The contributor put it bluntly: without this file, Claude writes like Claude. With it, Claude writes like you.
Here are a few easy rules you can borrow from the original poster to start your own:
- Ban filler words you’d never say out loud.
- Kill negative parallelism, the “it’s not just X, it’s Y” formula that screams robot.
- Note your real sentence rhythm, short and punchy or long and winding.
🎯 Your north star file
The third file, my-company.md, keeps the AI pointed at what matters right now. The author suggests keeping it over 1,000 tokens and updating it once a quarter. It holds your current goals, your main focus, and the things you’re actively saying no to. When the AI knows your priorities, its suggestions stop being generic and start being useful.
🌍 Build once, use everywhere
Here’s the payoff that I think makes the whole effort worth it. Once those three files exist, they’re portable. The person who shared this notes you can upload the same set to ChatGPT, Grok, or Gemini and get a consistent version of your brain across all of them. You can even hand the files to a teammate or a ghostwriter so they can write in your voice too. You build it one time and reuse it forever.
💡 Use cases worth trying
- Drafting emails and posts that already sound like you, with way less editing.
- Onboarding a new AI tool in seconds by pasting in your three files.
- Giving your team a shared “voice of the founder” so messaging stays consistent.
- Keeping every AI aligned with your current quarterly goals.
The line from the post that stuck with me: the mystery you’ve built your identity on is usually just being vague. Writing these files forces clarity, and clarity is what makes the AI finally get you.
If you’ve ever felt like AI output sounds flat and faceless, this system from the original creator is a smart fix. The full LinkedIn post has extra detail on each step, so check it out and start building your own brain files this week.
