- Refines them using the "Ralph Loop" until they hit 9.5+
- Generates PRDs (napkin sketch → full spec → investor-ready)

- Plans architecture with specific tech stacks and skills

"Validate my concept for a subscription box for houseplants"
"What are the weaknesses in my idea for a freelancer insurance platform?"
Pushing for higher scores

"Make this idea more defensible"
"How can I improve the virality of this concept?"
Going deeper
"Generate a PRD for this"
"Design the UI — I want a clean, minimal vibe"
"Plan the architecture using SvelteKit and Supabase"
"Create a launch checklist"
The full journey
"Let's go through the whole flow — brainstorm, validate, refine, PRD, design, architecture"
The Flow
Brainstorm → Validate → Refine → PRD → Design → Architecture → Checklist → Build!
| Stage | What Happens | Example Prompt |
|---|---|---|
| Brainstorm | Generate ideas with initial scores | "Ideas for busy parents" |
| Validate | Deep-dive scoring on 10 dimensions | "Score this idea..." |
| Refine | Ralph Loop until 9.5+ | "Iterate until it's great" |
| PRD | Product requirements doc | "Generate a PRD" |
| Design | UI/UX with one vibe question | "Design it — bold vibe" |
| Architecture | Tech stack + implementation | "Plan how to build this" |
| Checklist | YC-level launch prep | "Create launch checklist" |
| Build! | Start shipping | Use Spawner skills or DIY |
The Ralph Loop
Your Idea → Score → Feedback → Improve → Score → ... → 9.5+ Idea!
Ralph keeps iterating until your idea is ready. Each round:
- Scores on 10 dimensions (1-10 scale)
- Gives specific, actionable feedback
- Generates an improved version
PMF Scoring (10 Dimensions)
| Dimension | What It Measures |
|---|---|
| Problem Clarity | How clear and painful is the problem? |
| Market Size | TAM/SAM — how big is the opportunity? |
| Uniqueness | What's the 10x better angle? |
| Feasibility | Can you build MVP in 3 months? |
| Monetization | Clear path to revenue? |
| Timing | Why now? What changed? |
| Virality | Built-in sharing? Network effects? |
| Defensibility | Data moat? Switching costs? |
| Team Fit | Good for 2-3 person team? |
| Ralph Factor | Sounds dumb but actually genius? |
