Generating ideas

Pick a niche and let the generator propose ideas. It is best used as a starting point - a way to break a blank page - rather than a final answer. The real validation comes from tying an idea back to documented demand.

Evaluating an idea

  1. 1

    Describe the idea

    Enter the idea you want to test - either one the generator produced or one of your own.

  2. 2

    Run the evaluation

    The Idea Evaluator scores market potential, competition, and viability in under 30 seconds.

  3. 3

    Read the recommendations

    Review the actionable recommendations for sharpening the idea before you invest more time.

  4. 4

    Verify against real demand

    Take the survivors into complaint and pain point research to confirm the demand is documented.

Generate, then verify against real demand

A generated idea is a hypothesis. Confirm it against real evidence in <a href="/docs/pain-point-analysis">Pain point analysis</a> and <a href="/docs/saas-opportunities">SaaS opportunities</a> before you commit.

Generator vs evaluator

The two tools do opposite jobs. The Idea Generator creates ideas from nothing - you give it a niche and it proposes directions. The Idea Evaluator scores an idea you already have. If you arrived with a concept in mind, skip the generator and go straight to the evaluator. If you are staring at a blank page, start with the generator. For a full walkthrough of scoring an existing idea, see Validating with the Idea Evaluator.

Getting more from generated ideas

Generated ideas are strongest when you feed the generator context rather than a bare niche. The more specific the niche and the audience you describe, the more targeted the output. Then treat the results as a menu of hypotheses: pick the two or three that overlap with a real problem you have seen, and put those through evaluation and evidence checks. Ideas that cannot be tied to a documented, recurring complaint are the ones to drop first.

A generator is a starting line, not a finish line

The tool exists to overcome the blank page, not to make the build decision. Every generated idea still has to survive scoring and real demand evidence before it is worth your time.

Frequently asked questions

Is the idea generator free?

Yes. Both the Idea Generator and the Idea Evaluator are free tools. The generator spans 100+ niches, and the evaluator scores an idea in under 30 seconds.

Should I build whatever the generator suggests?

Treat generated ideas as hypotheses, not conclusions. The strongest ideas are the ones you can tie back to documented, high-severity pain points and evidence that people already pay in the category.

What is the difference between the generator and the evaluator?

The generator creates ideas from a niche you choose; the evaluator scores an idea you already have on market potential, competition, and viability. Use the generator to overcome a blank page and the evaluator to pressure-test any specific idea.
