Free SaaS idea validator
Validate your SaaS idea in 5 minutes.
Most founders waste months building before they know if anyone wants it. This free SaaS idea validator asks 3-5 short questions, then turns your fuzzy idea into a search-ready prompt that pulls real demand from Reddit, X, YouTube and TikTok. No signup. 2 sessions per day per IP.
What founders use the SaaS idea validator for
- Pressure-test a hunch before writing code. If we can't extract a clear audience and pain in 5 turns, neither can your future users.
- Sharpen a Reddit / X / YouTube search. Vague queries pull noise. The validator outputs a prompt sharp enough that the real Gorilla pipeline finds 3-5x more useful posts.
- Rewrite your landing page. The refined prompt usually surfaces the exact phrasing your buyers use — copy it onto your hero.
- Decide whether to keep building. If 5 turns of refinement still leave your idea fuzzy, that's a signal to talk to humans before adding more code.
How it works
- Paste your rough idea (one sentence is fine).
- Pick one of 3 idea-specific options per question, or type your own answer.
- The running prompt gets sharper after each turn.
- You stop when the prompt is search-ready, or after 5 turns max.
Why "validating an idea" usually means "narrowing the prompt"
Most idea-validation advice tells you to talk to 50 customers. That's good advice when you have 50 customers' worth of network. Most solo founders don't. The fastest cheap proxy is to find the people already complaining about the problem online and read what they say.
That requires a sharp search prompt. "A productivity tool" returns junk. "A weekly review template for solo founders managing 3+ side projects who keep dropping commitments" returns 80% useful posts. The validator gets you from the first form to the second in under 5 minutes.
