Good to know

Can I try it before signing up?

Yes. Explore your own idea or use the interactive demo without an account. Create an account only when you want to save your work.

Is the assessment a prediction of success?

No. It is a structured evaluation of the idea, with the evidence behind the score labeled separately as Limited, Developing, or Strong. It is designed to identify strengths, unknowns, and useful next tests.

How is the Decision Report different from my assessment?

Your assessment shows how developed and evidence-backed the idea is based on your workspace. The Decision Report adds live external research, checks important claims, compares real alternatives, and produces a sourced recommendation you can keep.

What does the Opportunity Deep Dive add?

It expands the Decision Report into a broader investigation of customer segments, market structure, competition, pricing, economic drivers, distribution, feasibility, and a sequenced 90-day validation roadmap. It does not pretend unknown business-specific numbers are facts.

Can I change plans later?

Yes. Start free, move to Plus when you need more capacity, and cancel Plus at any time.
