This quick comparison guided by the work of Darren Waldron cuts through the noise around generative AI tools and focuses on a more practical question: which tool is best for which task. Instead of treating AI platforms as interchangeable, the guide maps leading tools to distinct use cases—from everyday productivity and long-form thinking to research, document analysis, and real-time information—offering a simple framework for choosing based on function, not hype.
