SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Brainstorming ideas and validating them into a design document, not code, so teams can align before building.

Core Features & Use Cases

Phase-based diagnostic prompts for Startup mode (Phase 2A) to surface demand, the status quo, and narrow wedges with objective criteria.
Builder mode (Phase 2B) for creative ideation, rapid iteration, and concrete build steps for side projects, learning, or open-source work.
Outputs a structured design document that guides decision making, including a premises section, recommended approaches, and a concrete next action to take.

Quick Start

Describe your idea and start the diagnostic with Phase 2A questions to generate a design document.

FAQPage Schema

How do I turn a product idea into a design document without writing code?▼

To turn a product idea into a design document without coding, describe your concept to trigger diagnostic prompts that frame the problem and planned solution. This process outputs a structured design-doc format with premises, recommended approaches, and a concrete next-step action for team alignment.

What is the best way to validate startup ideas before building?▼

The best way to validate startup ideas before building is applying Phase 2A startup mode questions. These diagnostic prompts surface demand, analyze the status quo, and identify narrow wedges with objective criteria, guiding your product-focused diagnostics into a structured design document.

How do I brainstorm and iterate on side project ideas step by step?▼

To brainstorm and iterate on side project ideas step by step, use Phase 2B builder mode questions for open-ended ideation. This mode facilitates creative ideation and rapid iteration, ultimately guiding your open-source work or learning project to a concrete build step and action item.

Can I use design docs for decision-making in product management?▼

Yes, you can use design docs for decision-making in product management. The generated design document includes a premises section and recommended approaches, structuring your team's decision-making process before development begins and ending with a concrete next-step action.

How does ideation diagnostic mode work for framing product problems?▼

Ideation diagnostic mode works by applying phase-based questions to your initial concept, focusing on problem framing and planned solutions. It separates startup-focused demand validation from open-ended builder ideation, ensuring the final design document guides concrete action items.
