What’s the fastest way to build your first AI agent without coding?

I’m exploring AI agent Development from a non-technical perspective and want to understand how people are actually getting started quickly without writing code.

If you’ve already built (or attempted to build) an AI agent using no-code or low-code tools, I’d love to learn from your experience:

What tools or platforms did you use to build your first agent? How long did it take you to go from idea → working prototype? What kind of task or workflow did your agent handle? What were the biggest challenges you faced as a non-developer? Did the agent actually deliver value, or was it more of a learning experiment?

I’m especially interested in practical, real-world examples—not just theory. Screenshots, workflows, or tool stacks would be super helpful if you’re open to sharing.

Also curious: If you had to start over today, what would you do differently to build faster?

Looking forward to hearing how others are approaching this
