Pick the one that matches what you’re stuck on. Each asks you a few multiple-choice questions and gives you a straight answer, not a score, not a report you have to interpret.

You launched and the graph is flat. Five completely different reasons look identical from the outside, and their fixes point in opposite directions, so guessing wrong costs you a quarter. Three questions and you get which one you’re in.

Somebody told you they would use it, or that they loved it. Before you build anything on top of that sentence, five questions about that exact conversation will tell you whether it was evidence or good manners.

Something has been requested enough times that it’s getting hard to say no. Four questions separate a real need from a loud request, and give you a reason you can say out loud to the person who asked.

You have been going round the same decision for two weeks. Most people agonise over things they could undo in a week and rush the ones they live with for years — four questions tell you which kind yours is.

You’re wondering whether to put a price on it, or whether it’s too early and asking for money would kill the momentum you have. Four questions and you will know which.

You ship constantly and it does not feel like progress. Decisions come back, work gets thrown away, and the same argument returns every few weeks. Four questions and you will know which of four causes it is.
Yes. No account, no email, no trial that turns into something. There’s nothing to buy at the end of them.
They exist because the questions inside are the ones I ask in the first twenty minutes of any project, and there’s no reason to charge for the first twenty minutes.
Nowhere. Everything runs in your browser. Nothing is sent to a server, nothing is stored, and I never see what you clicked, which also means your result disappears when you close the tab.
Treat it as a strong opinion from somebody who has made the same call before, not a diagnosis. A handful of questions cannot know your product.
What it’s genuinely good at is stopping you from fixing the wrong thing. Most wasted quarters are not bad execution — they’re excellent execution pointed at the wrong problem.
There are five common reasons and in analytics they look identical: nobody saw it; they saw it and did not understand what it was; they understood it and did not need it; they needed it but moving off what they use today was too much work; or they tried it and it’s not good enough yet.
The fixes point in opposite directions. More traffic only helps the first one, a better product only helps the last one, which is why guessing is expensive. The first check tells you which one you’re in.
Four things separate evidence from good manners. Did they say it before you showed them your solution, or after? Do they already have a workaround they dislike? Have they done the thing again without you in the room? Can you name a second person who asked, unprompted?
Enthusiasm after a demo, with no workaround and no repeat use, is a no wearing better clothes.
Look at who asked and whether it was unprompted, what those people do about it today, and what measurably happens if you never build it.
Several users who each built their own ugly workaround is a need. One loud voice with no workaround behind it’s a preference, and preferences do not belong on a roadmap.
Please do — that’s the best use of them. Two people running the same check separately and comparing answers surfaces disagreements that meetings usually bury.
