A guide to AI prototyping for product managers

Colin Matthews · Lenny's Newsletter Freemium Beginner

A clear, tool by tool guide to turning an idea into a working prototype in minutes, aimed at people who do not code. It sorts the landscape into categories (chatbots, cloud builders, local assistants) so you understand what each type is good for rather than just chasing brand names. Useful whether you land on an AI builder or decide you need something more structured.

  • The tools split into clear categories, each suited to a different job
  • Prototyping in minutes is now realistic even with zero coding background
  • Includes prompt templates so your first attempt is not a blank page

It answers 3 questions

  1. Should I use an AI app builder like Lovable or Replit instead of traditional no-code?
  2. Should I learn Figma, and how much design do I really need?
  3. How do I use AI code generation tools like Cursor to go beyond what pure no-code allows without becoming a full-time developer?
