Your Claude. An extension of you.

Claude has memory. It picks up patterns. Calibrates over time. Projects, custom instructions, the skill builder — real features that help.

But calibrating from usage patterns is not the same as knowing you. And Claude’s own tools share the same limitation: they can only work with what you give them. They don’t know what questions to ask. They can’t detect the gap between how you describe yourself and how you actually communicate. They have nowhere to put the things that have never been written down.

The tools are there. The methodology to fill them was missing.

Paste “write like me” into a prompt. Upload a writing sample. Describe your voice in a sentence — “professional but approachable.”

None of it works. Not because the effort isn’t there. Because the method is wrong.

James Pennebaker — Professor Emeritus at the University of Texas at Austin, elected to the National Academy of Sciences, and among the most cited psychologists in the world — proved it. Four decades of research show that self-descriptions of communication style correlate with actual behavior at 0.29 out of 1.0. Without the right structure, you describe the communicator you aspire to be — not the one you actually are.

Most professionals who use Claude are domain experts. A lawyer with 20 years of case judgment. A consultant whose methodology lives in their instincts. A director who has internalized how to communicate risk to a board.

They know exactly what they want from Claude. They have no framework for giving Claude what it needs to know about them.

Without that framework, AI doesn’t just miss the mark. It flattens something you spent decades building. The judgment, the standards, the methodology that lives in your instincts — not in any document — gets averaged out. Generic output for everyone, regardless of what they’ve earned.

The gap isn’t self-knowledge. It’s translation. The framework for converting who you are into structured, AI-readable context didn’t exist.

Old School AI is an identity system for Claude. It encodes who you actually are — your background, values, communication style, how you operate, and professional expertise — into your Claude permanently. Every output Claude produces for you runs through that context. It stops guessing and starts knowing.

Three steps.

First, you complete the Old School AI session — a structured set of questions built specifically for people who've never been asked to articulate themselves to an AI. Most self-description fails because people describe their intentions rather than their behaviors. Our questions don't ask how you'd describe yourself. They ask about specific situations, real moments, actual decisions. Things you can recall — not things you'd have to construct. The structure does the work. You answer honestly.

The single highest-signal input isn't what you say about yourself. It's what you've already written. Real pieces of your work — with your own explanation of what makes each one yours — tell Claude more about how you actually communicate than any self-description ever could. We ask you to show us. Not tell us.

Second, Old School AI generates your Claude Skills file — a structured identity document that encodes everything into your Claude permanently.

Third, you upload it once. From the first conversation after setup, your Claude knows who it's working with. Your standards. Your way. Without you explaining yourself again.

Not a better prompt. A different Claude.

Two ways.

First, the method. Most people describe the communicator they aspire to be, not the one they actually are. Old School AI's questions are built to extract accurate self-knowledge — not aspirational self-description. The correlation between how people describe their communication style and how they actually communicate is about 0.29 out of 1.0. Our process is designed to close that gap.

Second, the permanence. What you tell Claude in a conversation disappears. What Old School AI encodes into your Claude Skills file is account-wide and always-on. Every new conversation starts with Claude already knowing you. Andrej Karpathy — founding member of OpenAI, former Director of AI at Tesla — named this context engineering: the principle that the quality of AI output is determined not by the prompt, but by the context surrounding it. That’s what a Claude Skills file is. Permanent context.

A Claude Skills file is a structured document that encodes your identity into Claude permanently. It lives in your Claude account as a Skill — active across every conversation, on every device, on every Claude plan including the free plan. You upload it once. It runs forever.

No. Claude Skills work on every Claude plan, including the free tier. You do need to enable Code Execution in your Claude settings to activate Skills — we walk you through exactly how in your setup guide.

Personal (free) takes 30–45 minutes done properly. Personal + Professional takes 90 minutes to 2 hours total. You can complete it in multiple sessions — your progress saves automatically.

The questions are specific. The structure does the work. The quality of what your Claude gets is directly determined by the care you bring to your answers.

Do it once. Do it right.

No. Old School AI is an independent product. We are not affiliated with, endorsed by, or connected to Anthropic or Claude in any way. We build for Claude because it's the best AI platform for what we do — not because of any relationship with the people who built it.

Your profile is yours to update anytime. When you update your answers, your Claude Skills file regenerates automatically. Your Claude stays current.

No. Tools like Obsidian and the Second Brain methodology are excellent for managing what you've already documented — notes, articles, research you've captured over time.

Old School AI is for what was never written down. Your identity, your expertise, your professional position — the things that live in your head, not in any file. Tiago Forte built the Second Brain to store what you know. We built Old School AI to encode who you are.

If you already have a Second Brain: Old School AI is the identity layer your vault was missing.

Personal + Professional includes a 14-day free trial. Card required at signup — you won't be charged until day 15. Cancel anytime during the trial in your account settings and you won't be charged.

If you cancel after the trial, you keep access through the end of your annual term. Your Claude Skills file is yours to keep regardless.

Yes — and the free AI Platform Migration Coach skill walks you through it interactively. Whether you're coming from ChatGPT, Gemini, Grok, or Perplexity, the skill guides you through what to extract, how to format it, and how to import it into Claude. For a deep written guide focused on ChatGPT specifically, we have that too.
