Stage 0 · Refine

Validate and sharpen your SaaS idea in 3-5 questions.

Free SaaS idea refiner. No signup. Built for solo founders with a rough idea who need it tight enough to actually find their audience. We ask short, idea-specific questions and rewrite the prompt as you answer. 2 sessions per day per IP.

When to use the validator

Mostly four situations:

  • You want to pressure-test a hunch before writing code. If we cannot surface a clear audience and pain in 5 turns, neither can your future users.
  • You need to sharpen the prompt that finds your audience. Vague queries pull noise. Sharp ones pull posts you can actually reply to.
  • You want better landing copy. The refined prompt usually surfaces the exact phrasing your audience uses. Paste it onto your hero.
  • You are deciding whether to keep building. 5 turns of refinement and still fuzzy? Talk to humans before adding more code.

Why it matters

Vague ideas pull vague results. "A tool for founders" returns junk. "A weekly review template for solo founders managing 3+ side projects who keep dropping commitments" returns posts you can actually act on. 60 seconds with this tool gets you from the first to the second.

Sharper prompt in, more of your audience out. That is the whole reason it exists.
