Guide

Vibe coding is great for momentum. Spec-driven building is what keeps the product coherent.

Ad hoc prompting can get a demo on screen quickly. LaunchChair is for the next step: preserving product context, scope, acceptance criteria, SEO direction, and launch strategy as the product becomes real.

Useful for experiments

Vibe coding is fast when the stakes are low.

For demos, learning, throwaway experiments, and early visual exploration, loose prompting can be enough. The issues appear when the product needs users, data, edge cases, positioning, and a launch path.

Where it breaks

The product starts drifting when context lives only in chat.

As features stack up, the build needs memory: what the product is, who it serves, what the MVP includes, what should be avoided, and how the public story should sound.

Repeated context setup

Feature scope creep

Inconsistent screens and data boundaries

Launch and SEO work disconnected from the product

LaunchChair approach

Spec-driven builds keep the context reusable.

LaunchChair stores the decisions and generates prompts from them. That gives AI tools a better starting point than blank chat while keeping build execution, landing page copy, SEO, and launch workflow aligned.
