# Cutline

> Cutline is AI technical product management software that helps founders and developers vibecode safely and stably. It validates product ideas, extracts hidden technical constraints, and gives AI coding agents the product context they need to generate production-ready code.

## What is Safe Vibecoding?

Safe vibecoding is the practice of using generative AI coding agents for rapid development while maintaining engineering rigor through automated constraint extraction, pre-mortem risk analysis, and dependency mapping. Cutline is the validation layer that makes vibecoding sustainable for production software.

## What Cutline Does

Cutline provides AI-powered product management for the vibecoding era:

- **Pre-Mortem Analysis**: Identifies why your product might fail before you build it. Analyzes market risk, technical risk, business model risk, and competitive risk. Surfaces hidden assumptions and suggests experiments to validate them.
- **AI Persona Testing**: Chat with synthetic customers who represent your target users. Test messaging, pricing, and positioning with realistic objections—user research at AI speed.
- **Constraint Extraction Engine**: Ingests natural language product descriptions and automatically extracts non-functional requirements (latency, auth patterns, data privacy) that most prompts miss.
- **MCP Integration**: Connects to AI coding tools (Cursor, Claude Code, Windsurf, Antigravity) via Model Context Protocol. Your AI coding agent gets product context, constraints, and validated decisions while it works.
- **Product Context Graph**: A connected network of requirements, constraints, validated assumptions, persona insights, and feature priorities that flows to AI agents so they understand not just what to build but why.

## About

Cutline was founded by Kyle Grove, a machine learning expert who led AI teams at eBay, Upwork, and LivePerson. He built Cutline to solve the problem of building products nobody wants—the "vibecoding paradox" where AI makes building 10-50x faster but doesn't improve product judgment.
