Good to know

What your score actually measures

Think of your score as a checkup, not a prediction. Your idea is scored across five dimensions founders check every time: problem urgency, market size, competition, willingness to pay, and personal fit. Each is weighted equally, so no single strength can hide a real weakness, and the total lands out of 100.

Why these five dimensions decide an idea

Picture five ways a business idea can quietly fail: nobody cares, too few people share the problem, competitors own the space, no one will pay, or you won't stick with it. These five dimensions are exactly those failure modes. One weak spot is survivable, but two at once is the pattern that sinks most ideas.

What a low score is really telling you

A score under 40 isn't a verdict that your idea is bad, it's a signal one dimension is weak enough to sink everything else, most often willingness to pay. Founders often confirm people have a problem but never check if they'll pay to fix it. The fix is to go straight at that weak dimension, not polish what already works.

Reading your strongest and weakest dimensions

Look at the gap between your strongest and weakest dimension, not just the number. A big gap means real potential held back by one fixable weakness, so closing it is your highest-leverage move. A small gap means the idea is even all around, and the band tells you whether that evenness is strong or thin.

Frequently asked questions

How is the score calculated?

Each dimension is a few yes/no checks answered by an AI scoring model as you type, averaged into a score from 0 to 100. The five are weighted equally into the overall score out of 100, so the headline number always reconciles with the dimensions beneath it. Ask for feedback and Claude writes what to fix.

What counts as a good score?

Under 40 needs rework, 40–69 is promising, 70+ is strong. Which dimension is weak matters more than the overall band.

Does a high score mean my idea will succeed?

No. Nothing can promise that. It means the idea is well-formed across five common failure points; execution and luck still decide.

Why might the score change if I reword my idea?

The score reflects what you describe, so a clearer, more specific description usually scores more accurately. Vague ideas get graded on the little they say — add the audience and the problem you solve for a sharper read.

Do you store my idea?

No. Your idea description is sent to our AI providers (Anthropic and TypeSafe) to generate the score and feedback, and we don't save it afterward — no account, no database. Free, no sign-up.
