Building products with AI

From tool to product

Using Claude yourself is one thing — building a product others pay for is another. An AI product solves a concrete problem for a defined audience, wraps Claude functionality in a user-friendly interface and has a business model that generates recurring revenue.

🎯

Niche over breadth — an AI product for plumbers writing quotes is more valuable than a general writing tool. Narrower audience = higher willingness to pay.

🔄

Recurring revenue — build subscription models, not one-time sales. Monthly payment gives predictable income.

The key: the system prompt is the product

What separates your AI product from users just using Claude.ai directly is your system prompt. It is your secret sauce — domain knowledge, tone, constraints and instructions that make Claude a specialist for your specific audience.

Minimum viable AI product

💡 MVP checklist:
✅ Simple landing page explaining the product
✅ Registration and login
✅ One core function that solves one problem
✅ Payment integration (even if manual at first)
✅ Simple logging of API calls and costs
✅ Contact option for support

Everything else is nice-to-have. Launch and validate demand first.

🎯 Test your knowledge

Test yourself — completely optional, but fun! 🎯
