Market Size & Growth

Generative AI is a $40B+ market growing at 40%+ CAGR. But the underlying models (OpenAI, Anthropic) capture the vast majority of that value.

Competition Level

Hyper-competitive. If your product is just a thin UI over an LLM prompt ("write a blog post"), you will face a dozen clones within a week, driving pricing to the floor.

What founders on Reddit tend to say

r/SaaS builders often describe heavy churn on simple AI wrappers. The successful ones are deeply integrated into existing workflows (like an AI tool specifically for dental office billing) rather than generic text generation.

Keyword Demand & Search Intent

Astronomical. Queries like "AI for [X]" are growing exponentially. The demand is real, but the challenge is building a product that retains users after the novelty wears off.

Don't build based on a blog post.
