Seven Thinking Modules

Each module tackles a different thinking challenge, powered by AI.

Prerequisite Mapper

Break any goal into what must be true first. AI recursively decomposes until you hit actionable foundations.

Assumption Register

Surface the hidden beliefs you didn't know you were making. AI finds resource, technical, and human assumptions.

Handover Machine

Extract tacit knowledge before it walks out the door. AI generates probing interview questions.

Constraint Ratchet

Creativity under pressure. Timed challenges with escalating constraints. AI evaluates your output.

Collision Engine

Spark original ideas by colliding your problem with random domains. AI finds unexpected connections.

Fragment Resurrector

Abandoned drafts deserve a second life. Archive them, and AI suggests how to revive them later.

Inverse Brief

Define by exclusion. State what must NOT happen, and AI maps the remaining possibility space.

How It Works

1

Add your AI key

Go to Settings and add your OpenAI, Anthropic (Claude), or Google (Gemini) API key. Your key is stored locally in your browser - we never see it.

2

Define your goal

Start with the Prerequisite Mapper. Enter what you're trying to achieve and let AI break it down into foundations.

3

Surface blind spots

Use Assumptions to find hidden beliefs. Use Inverse Brief to define constraints. Use Collisions to spark new ideas.

4

Export your clarity

Generate an AI summary report, export to Markdown, or create a visual PDF. Share with your team or keep for reference.
