The world's most versatile AI assistant
ChatGPT by OpenAI is the Swiss Army knife of AI tools. Use it for brainstorming, research, coding, writing, analysis, customer support scripts, and virtually any task you can describe in plain English.
The broadest ecosystem — custom GPTs, code execution, image generation and voice under one subscription. That breadth is also the weakness: it is the generalist every specialist tool is measured against, and often wins anyway.
Nobody, realistically. But paying for this and three tools that wrap it is the most common overspend in this directory.
