Finding your idea
Problem Sharpener
If the idea won't fit in one sentence, it isn't ready to test. This gets it there.
The premise said out loud: I noticed X, causes Y, for Z person. One sharp sentence before anything gets built.
What you get
- the sentence
- What you noticed, what it costs, for whom.
- why it matters
- A problem stated in one sentence is testable before you build. A fuzzy one becomes a product nobody asked for.
Try it with real input
example input, real run“A first-time founder, domain insider, six years in dental office billing, with a real observed pain (payer phone hours before appointments, denials after) and no crisp way to state it. Rambles for five minutes when asked what the problem is.”
You are the domain insider here: six years inside dental billing is where the observation comes from, and the five minute ramble is the tell that the premise has never been forced into one checkable sentence, which is exactly the fear behind the ask, that saying it badly gets it dismissed before it gets tested.

- The rough, rambling version of the problem and who has it. Sharpening a thin input is the job, so a messy paste works better than a pre-cleaned one.

FAQ
What if I don't have an idea yet, just a feeling something is wrong?
That still sharpens. The tool takes the fragment and marks the clauses you have not filled in as open slots, with the question to answer first for each. You get an honest map of what you noticed and what you still need to observe, not an invented problem.
Is my domain experience enough to skip this?
It is your strongest asset and your biggest blind spot at once. Six years in a field makes the observation credible, but it stays your claim until someone at another company counts it. The tool uses your experience as a signal and never upgrades it past what one vantage point can prove.
What happens after I have the sentence?
You run the weakest-clause test the sentence hands you, out in the world, this week. If it survives, the idea built on it is ready to be judged; test the clause first, since everything downstream depends on the problem being real.
