What You’ll Learn:

  • Why “free to build” doesn’t mean “no cost”
  • How AI prototyping tools help with assumption testing
  • Common pitfalls (and how to avoid them)
  • Why engineering skills still matter in a no-code world
  • The types of prototypes that are perfect for AI tools
  • How these tools change team collaboration and speed

    • Key Takeaways:

    • AI tools can help build usable prototypes in hours—not weeks.
    • These tools are great for fast, interactive assumption tests.
    • You still need engineering know-how to troubleshoot or guide LLMs effectively.
    • Product teams benefit most when they build and test together.
    • Even failed prototypes offer valuable learning.
