Why it matters
It is the default reference point for what a general assistant can do, which makes it the baseline every other tool gets compared against.
ChatGPT
An all-purpose AI assistant for writing, research, coding, and productivity.

ChatGPT is the general-purpose end of the assistant spectrum: one conversation surface that absorbs web search, file reading, code execution and image generation instead of specialising in any of them. That breadth is both the strength and the trade-off — it will get you a competent answer in almost any domain, and a purpose-built tool will usually beat it inside that domain. Practically, it earns its place as the tool you reach for before you know what shape the problem has, and hand off once the shape is clear.
