Quick questions

What do I need to run this?

A Mac (M1+) or Windows (16GB+ RAM) and Claude Code (Anthropic's CLI). We recommend the Max plan with Opus 4.6 for the best experience. The guide walks you from zero to running.

Why Claude Code specifically?

Claude Code reads the CLAUDE.md schema file automatically when you open it in a folder. It has full file system access, can read your raw/ material, create wiki/ pages, and maintain your entire knowledge base. Opus 4.6 on the Max plan gives you the deepest reasoning and largest context window — ideal for synthesising across a large knowledge base.

Does it work with other tools?

Yes — Cursor, Windsurf, and other AI editors that read CLAUDE.md will work. But Claude Code with Opus 4.6 is what this was designed and tested for.

Can I upgrade to done-for-you later?

Yes. Your kit purchase is credited in full towards the Standard ($7,500) or Premium ($12,500) build.

What's the difference between Standard and Pro?

Standard gives you the raw kit — you replace the placeholders yourself. Pro lets you fill in a form and generates a personalised CLAUDE.md with your name, focus areas, and role already configured. Everything happens in your browser — nothing is sent to any server. Pro also includes 30 days email support.
