Is Your Idea Worth Building?

You answer 20 multiple-choice questions across 5 categories: market potential, competition, feasibility, monetization, and personal fit. Each answer scores 0-3 points. Your total score (0-60) determines your idea's rating: Kill It, Needs Work, Promising, or Build It.

Yes, completely free. No signup, no email required, no hidden fees. Take the quiz as many times as you want with different ideas.

Different, not necessarily better. AI validators analyze your idea description and give market data. Our tool makes YOU think critically about your idea by asking the right questions. Both approaches complement each other well.

We recommend 36+ (Promising) as the minimum to justify building an MVP. But a score of 21-35 doesn't mean give up — it means iterate on the weak areas first. Below 20 suggests a fundamental rethink.

Absolutely. The questions apply to any project: a SaaS product, a mobile app, an open-source tool, or even a weekend hack. If you're investing time in building something, it's worth validating first.

The score reflects how well YOU understand your idea across key dimensions. It's a self-assessment, not a market prediction. The value isn't in the number — it's in the questions that make you confront blind spots you might be ignoring.

A high score means your idea has strong fundamentals according to your assessment, but execution matters more than any score. Timing, team, luck — there are factors no quiz can predict. Think of this as a filter, not a guarantee.

Be brutally honest. The whole point is to catch weaknesses before you invest months of your life. If you sugarcoat your answers, you're only fooling yourself. The best founders are honest about their idea's flaws.

Each of the 20 questions has 4 options scored 0-3 points. Maximum score is 60 (20 × 3). Categories are equally weighted with 4 questions each, so each category maxes out at 12 points. No tricks, no hidden weights.

Yes! Take the quiz once per idea and screenshot or note your scores. The category breakdown is especially useful for comparison — one idea might score high on market but low on feasibility, while another shows the opposite pattern.

Market Potential and Monetization are usually the most critical. A brilliant product in a dead market won't make money. That said, Personal Fit is underrated — founders who aren't passionate tend to quit when things get hard.

No. Everything runs in your browser. We don't collect, store, or transmit your answers. Your ideas stay private.

Low scores don't mean bad ideas — they mean high risk. Many successful companies started with ideas that would have scored low. The difference is the founders validated key assumptions before going all-in. Use the low-scoring categories as a roadmap for what to research and validate next.
