How it works

1. You describe an idea

Type a sentence or two, up to 600 characters. One clear idea works best: what it is and who it is for.

2. A machine asks several narrow questions

Instead of asking an AI to write an opinion, the site asks an AI model built for fast, structured judgments a set of small, specific questions about your idea, such as:

• Does it solve a problem people actually have?
• Would a normal person understand it quickly?
• Is there a plausible customer?
• Is there a realistic way to make money?
• How hard would it be to build and run?
• Does it basically exist already?
• Does it sound pointless, or potentially harmful?

Each question comes back as a probability or a rating, not as free text.

3. The answers are combined into one verdict

Fixed rules in our code turn those answers into the verdict, the percentage, the five scores out of ten and the “biggest problem” line. The same answers always produce the same verdict. A sound idea is not marked stupid just because it sounds unusual, but an unusual idea with no real need is.

The one-line roast is picked from a set of pre-written lines that match the result. It is not generated on the spot.

Reading the result

• The percentage shows how strongly the result leans one way: “83% not stupid” is a firmer verdict than “57% not stupid”.
• The scores rate need, how easy it is to understand, money potential and originality (higher is better), and execution difficulty (higher is harder).
• “It's torn on this one” appears when the underlying judgments were unsure.

Limits

It is a snap judgment. It does not research your market, check competitors or know anything about you. It works best in English. Treat it as a first reaction, not a forecast. See examples of how it rates different kinds of ideas. The exact weights and verdict thresholds are in what the verdicts and percentages mean.

What happens to your idea

Your idea is sent from our server to the AI provider to be evaluated, and the verdict is sent back to you. Our application does not store it. Details are on the privacy page.
