ChatGPT is the ultimate generalist. It can write code, draft emails, and brainstorm ideas. But when it comes to high-stakes decisions, you don't need a brainstorming buddy—you need a decision engine.
When you ask ChatGPT "Should I quit my job to build a startup?", it will give you a bulleted list of pros and cons. It leaves the cognitive load of deciding entirely on your shoulders.
When you ask Persona AI the exact same question, it computes constraints. It asks for your runway, your risk tolerance, and it runs a pre-mortem. Ultimately, it gives you a direct verdict and concrete conditions under which you should kill the idea entirely. It doesn't chat; it decides.
