Here's something I didn't expect to care about: what tool I use to build my agents.

It can make a pretty big difference.

You can build Agent.ai agents in JSON, which means you can use any tool you want — Cursor, Claude Code, whatever. I've been using Cursor, and it's helped me a ton.

The reason is context.

Tal Raviv and Aman Khan wrote a piece in Lenny's Newsletter arguing that the fastest way to build real AI intuition is to move out of consumer tools like ChatGPT and into coding agents like Cursor — even for non-technical work. The difference isn't the AI model. It's that Cursor shows you exactly what context your AI is working with, and lets you control it. You can see every file. You can point at exactly what you want Claude to reference in a particular chat.

That's what changed things for me. The Agent.ai team set up a structure where I have actual files for my PRD, design guidelines, target persona, and criteria for success. I can point Claude Code directly at those files while I'm building. You've probably heard "context engineering" thrown around — this is what it actually looks like in practice. You control what the AI sees, so it stays on track with your plan instead of drifting.

ChatGPT and Claude.ai are great. But the context is invisible. Cursor makes it visible.

If you're building anything with AI right now, the question worth asking is: can your AI actually see your plan?
