Vibeharshing Platform

Your AI Product Cofounder Who Harshes the Vibe

Finds risks, validates demand, and writes product docs while you drink a work-adjacent beverage of your choice.

Get Started

Built for founders, PMs, and indie hackers who hate building the wrong thing

🚀 Early Access

Built for founders tired of:

ChatGPT saying "You're Absolutely Right!!!" to everything
Building features nobody wants
Wasting weeks on unvalidated slop

Wall of Shame

"Did My AI Transformation in an afternoon!"

Sloppy McSlopperson

VP of AI Buzzword Enforcement, ToDoLy

"Finally added AI to my AI! Now my roadmap has AI-powered AI features with AI on top!"

Chad Disruption

Chief Vibes Officer, StealthMode.io

"Cutline told me NOT to build 47 of my features. Ignored them all. My app has 3 users now (all bots)."

Brock Shipper

Founder & Full-Stack Everything, MoveF4st.app

"Spent 6 months building in stealth. Cutline would've saved me, but I was too busy grinding."

Preston Hustle

CEO of Grinding, PivotPending.com

"Web3 meets AI meets blockchain meets... wait, what problem were we solving?"

Devin Synergy

Head of Innovation Theater, Unicorn.xyz
