Mythos

Pick your brand's archetype.
Lock it into your AI.

Every brand that compounds plays one mythic role consistently — and gets recognized for it. Mythos picks that role with you, layers in a personality across three independent dimensions, and turns the combination into a Claude skill so every email, landing page, and post from now on speaks in the same voice. Twelve archetypes × thousands of personality combinations — yours is one of them.

How it works

01

Describe your company

Five short answers — one-liner, what you do, who you serve, anti-pitch. Just enough specifics that the AI writes for you, not the average SaaS.

02

Pick an archetype

The mythic story role your brand plays — one of 12. The story-role axis. This is the constraint that stops your copy from sounding like four different companies across landing pages, docs, and posts.

03

Layer in personality

Three more axes — Keirsey temperament, Aaker dimensions, Rogers adoption stance — each pickable independently. The archetype gives the story; personality gives the voice. The combination is what makes the skill yours, not a preset.

What you walk away with

·SKILL.md

A portable brand-voice skill for your AI assistants.

The app generates a single SKILL.md file that encodes your archetype, personality, and company brief. Upload it at claude.ai/customize/skills and it's available in every Claude conversation from then on — every email, landing page, ad, or social post comes back in your voice, without re-pasting the brief each session. (If you use Claude Code, you can also drop it into ~/.claude/skills/or any project's .claude/skills/.)

See it in action

One prompt. Two axes. Thousands of voices.

Imagine you built a modern email client. You ask Claude the same question every time — but each time, you are using a different Mythos skill. Below: first the archetype axis changes the brand entirely, then the personality layer reshapes the same archetype into very different voices. Your final skill is one combination of four picks.

The Sage skill

Email, finally optimized by people who studied it.

The inbox of record.

We rewrote what mail knows about you. The model is ours, the inbox is yours.

Twelve archetypes × four personality picks (Keirsey + up to two Aaker + Rogers) ≈ 9,600 voice combinations. Your skill is one of them.
