NewA new product line — functional Tools

Functional tools for Claude, ChatGPT, and any LLM.

Where our persona frameworks distil how specific people think, our Tools distil specific recurring tasks — making them visible, repeatable, and yours to keep.

A persona changes whose head your AI thinks with. A Tool changes what it does — running the same considered procedure every time you face the difficult email, the senior hire, the pricing call, or the client you can't read.

Tools vs personas

Why these aren't personas.

A persona framework — Buffett, Feynman, Kobe — answers the question “how would this person think about my problem?” It changes the voice and the mental models your AI brings. It's broad by design: you point it at anything and it reasons in character.

A Tool is narrower and more demanding. It answers “what is the right procedure for this specific task, and will you run it properly every time?” It doesn't adopt a voice; it runs steps — diagnose, generate options, surface the trade-off, produce the artefact — in the same order whether you're calm or under pressure. That's the part people skip when they do it themselves, and it's the part that's worth engineering once and keeping.

Which is why a Tool is priced like a tool rather than an impulse buy. A $4.99 persona is something you try. A Tool is something you reach for, repeatedly, on the days the task actually matters — the senior hire, the pricing call, the client you're about to lose.
