For Context
Documented Feedback on Preuve AI
Genuinely strong at sourcing market evidence, but stops there — no persona testing, no unit economics, no verdict.
- Scans 60+ data sources for market evidence — real strength — but delivers a static report and nothing else.
- No persona simulation or synthetic consumer testing of any kind.
- No launch economics or financial modeling.
- Still grouped in the market's discredited low-cost tier alongside tools criticized for "unsourced AI estimates."
