Hey HN,
We all know the pain: The code is clean, the product is solid, but the landing page isn't converting.
I built Vect (vect.pro) to solve this. It’s an Autonomous Marketing OS, but the core feature is the Conversion Killer Detector.
Instead of just "generating text", it acts as a hostile auditor. It simulates a skeptical buyer's inner monologue to flag exactly where your copy is vague, passive, or confusing.
The Tech:
Frontend: React + TypeScript (Command Center UI).
Reasoning: Gemini 2.5 Flash for the audit logic.
Simulation: It runs your copy through 10 distinct "Skeptic" personas to find friction points.
It’s free to try the audit. I built this to help technical founders stop losing sales to bad copy.
