Free tools for founders
Four tools grounded in real public community discussions — every score, count and quote is verified against stored evidence, never invented. Start with whichever question you're asking today.
AI Idea Reality Check
Paste an idea from ChatGPT or Claude and check it against real evidence.
- A clear evidence verdict — not a success promise
- What matches and what the evidence doesn't yet support
- The problem you're assuming vs. what people actually say
Startup Idea Validator
Check whether real people already discuss the problem behind your idea.
- Evidence-backed 0–100 score with a visible breakdown
- Recurring problem themes, with verbatim quotes
- Honest risks and what to test next
Problem Gap Finder
Name a market and see the recurring unmet needs inside it.
- Ranked gap cards, scored by real demand
- The workarounds people rely on today
- Why each gap stays unresolved
Find My Customers
See which communities your customers talk in — and how they describe the problem.
- Ranked communities, with a promotional-risk check
- Real customer phrases in their own words
- Specific threads worth joining (not leads to spam)
