For US founders building with AI

Score Your Lovable, Cursor, or Bolt Idea Before You Build

You can ship an MVP in a weekend with Lovable or Cursor. The bottleneck isn't building anymore. It's knowing what to build. Idea Bob scores your concept against 9 dimensions, pressure-tests it, and generates a self-contained builder prompt you can paste straight into Lovable or Cursor.

  • Designed for the AI-builder generation: Lovable, Cursor, Bolt.new, v0, Replit Agent
  • 60-second Opportunity Score with BUILD NOW / REFINE / KILL recommendation
  • Auto-generates a Lovable/Cursor-ready prompt with goal, files, criteria, and guardrails
  • Free to start, designed for US-based indie hackers and solo founders

Why "build first, validate later" stopped working in 2026

In 2023, building a SaaS MVP took 3 months. Today, with Lovable and Cursor, it takes a weekend. That sounds great until you realize it means everyone is shipping, and 99% of those shipped products get zero traction.

When building is cheap, the only durable advantage is picking the right thing to build. That's exactly what Idea Bob is for: a sharp pre-build filter so you spend your weekends on ideas that actually have a market.

The builder-ready prompt feature

After Idea Bob scores your idea, it generates a structured prompt specifically formatted for AI builders like Lovable, Cursor, and Bolt. Each prompt includes a clear goal, full project context, the specific files to touch, acceptance criteria, and explicit do/don't guidelines so the AI builder ships the right thing on the first try.

No more vague "build me a dashboard" prompts that produce generic output. Every brief is anchored to your specific scored idea, so the resulting code matches your validated concept.

How it integrates with your AI builder workflow

Step 1: Describe your idea in Idea Bob (one paragraph). Step 2: Get the 60-second Opportunity Score and decision label. Step 3: If GO, run the deeper validation tools (Pressure Test, Mom Test scripts, Market Research). Step 4: Copy the builder-ready prompt and paste it into Lovable, Cursor, or Bolt.

For Cursor users specifically, Idea Bob also exposes an MCP endpoint so the validated context is available directly inside your IDE, no copy-paste required.

Frequently asked questions

Is this only for Lovable users?

No. The builder prompts are formatted to work with any AI builder: Lovable, Cursor, Bolt.new, v0, Replit Agent, Windsurf, or Continue. The structure is universal.

How is this different from just asking ChatGPT to score my idea?

ChatGPT will tell you anything sounds great. Idea Bob uses a fixed 9-dimension framework with weighted scoring, runs live market data through Firecrawl, and pressure-tests against Paul Graham's actual questions. It's designed to find reasons your idea will fail.

Do you have an MCP server for Cursor?

Yes. See /mcp for setup. You can validate ideas without leaving your IDE.

How much does it cost?

Free to start with 3 idea scores per month. Hobbyist is $12/month USD, or $10/month billed yearly. Builder is $29/month USD billed yearly, or $49 billed monthly, and adds unlimited AI analyses.
