Frequently asked questions
- How does the SaaS idea validator work?
- You describe your idea in a sentence. PainMiner matches it against a corpus of real, scored user complaints and returns a demand read: how many related complaints exist, their average commercial-intent score, whether the trend is rising, and which categories they cluster in.
- Is the idea validator free?
- Yes. The demand read and sample matching complaints are free. A free account unlocks the full list of matching opportunities with descriptions, sources, and validation playbooks.
- What does a strong demand signal mean?
- It means many real complaints match your idea and they score high on commercial intent, so people are actively frustrated and likely to pay for a fix. It is still smart to validate directly with a few target users before building.
- What if no complaints match my idea?
- Either the idea is genuinely novel (validate it from scratch with real users) or people describe the pain in different words. Try rephrasing with the language your users would actually use.
