ChatGPT is the assistant most people mean when they say AI. Its strength is breadth: drafting, summarising, translating, writing code, and reasoning through a problem all work reasonably well in one place, and the mobile apps are good enough that many people use it as a search replacement. The free tier runs a smaller model and caps usage at peak times. The paid tier buys stronger reasoning models, file and image analysis, and higher limits.
Where it falls short
It states wrong things confidently, and long conversations drift.
