Product Validation

Paste your feature idea, product concept, or pitch. SPM surfaces the assumptions you are betting on, ranks them by risk, and builds a validation plan with the cheapest test for each one. Find out what could be wrong before you build it.

Find the riskiest bet first

Assumptions ranked so you test what matters before you build.

Cheapest test, not generic advice

A specific method per assumption, ordered by cost and speed.

Know what counts as proof

A clear pass/fail signal for every test, so results are not ambiguous.

How it works

  1. 1
    Describe what you want to build

    A feature idea, a product concept, a one-paragraph pitch, or rough notes. State the problem, the user, and why you believe it will work. Any level of detail works.

  2. 2
    SPM surfaces your hidden assumptions

    The AI separates what you know from what you are betting on. It names the desirability, viability, and feasibility assumptions baked into your idea and ranks them by how much risk each one carries.

  3. 3
    Get a validation plan you can run this week

    Each risky assumption gets the cheapest test that could disprove it: a customer interview, a landing-page test, a concierge run, a fake-door experiment. With a pass/fail signal so you know what counts as proof.

What you get

Risk-ranked assumption list

Every assumption your idea depends on, ordered by how badly a wrong answer would hurt.

Cheapest test per assumption

Not "do user research." A specific method matched to each assumption, ordered by cost and speed.

Pass/fail signal for each test

What result would validate the assumption and what would kill it. No ambiguous outcomes.

Desirability, viability, feasibility split

Assumptions sorted by type so you can see whether the real risk is the user, the business, or the build.

FAQ

Is this free?
Yes. 2 free validation plans, no sign-up required. Sign in with Google for unlimited access and 30 expert document reviews.
What input works best?
A feature idea or product concept with the problem, the user, and your reasoning. Even a rough pitch works. The more you state your beliefs, the more assumptions SPM can surface.
How is this different from asking ChatGPT to validate my idea?
ChatGPT tends to agree with you. SPM separates fact from assumption, ranks assumptions by risk, and prescribes a specific test for each one instead of generic encouragement.
Can SPM also review my full PRD?
Yes. SPM reviews your PRD against 30 expert standards covering problem definition, success metrics, risks, and edge cases. You validated one idea, what if you could pressure-test the whole spec before engineering starts? Try the full SPM review
