Beta — For founders building AI-first companies

You know what you're building.
Now articulate why it matters.

A guided conversation that helps you move from intuition to clarity—so you can share your vision with your team, your investors, and the AI tools that build alongside you.

“I know exactly what I want to build. I just can't explain it in a way that captures why it matters.”

— Every founder, at some point

What emerges from your session

Four documents that capture your product's essence

Not templates filled in. Not generic frameworks. Your words, refined into something you can actually use.

Soul

The core purpose, character, and felt sense of your product. What makes it distinctly yours.

SOUL.md

Boundaries

The lines you won't cross. The things you'll say no to, even when they seem tempting.

BOUNDARIES.md

Aspirations

The direction you're reaching toward. Not a roadmap—a compass.

ASPIRATIONS.md

Voice

Real examples of how your product speaks—and doesn't. The tone that feels authentically you.

VOICE.md

What you can do with these documents

Feed to AI tools

Give Claude, Cursor, or Copilot context that makes their output feel like you.

Align your team

Onboard new hires with clarity on what you're building and why it matters.

Guide decisions

When you're unsure, reference the soul. The answer is usually there.

Why this works

The clarity already lives in you

You'll say things to AI you won't say to consultants.

Less performance. More honesty. The real thoughts emerge.

The questions come from real founder sessions.

Structured to find the threads worth pulling. Not a generic framework.

The output is immediately useful.

Share with your team. Feed to AI coding assistants. Reference in investor conversations.

Who we're looking for

Founders building AI-first products who want to articulate what makes their approach distinctive.

Teams using AI tools like Claude, Cursor, or Copilot—and want those tools to truly understand what they're building.

People who know taste matters in AI products, and want to capture theirs in a usable format.

Two ways to work with us

Choose what fits your workflow

Both include the same 60-90 minute soul-building session. The difference is what happens after.

Your ideas stay yours

We know you're sharing something valuable. Here's how we protect it.

We don't read your sessions

Your conversations and documents are private. Our team has no access to your ideas, product details, or generated documents.

Your data isn't used for training

We use Claude via Anthropic's API with zero data retention. Your session content is not used to train AI models.

We improve through feedback, not surveillance

We rely on what you choose to share with us—direct feedback, feature requests, and conversations you opt into.

Your product has a soul.

Let's find the words for it.
