ChatGPT has become the default entry point for most people trying AI for the first time, and after extended daily use it still holds up as a genuinely useful all-rounder rather than just a familiar name.
Where it shines is breadth: the same interface handles a first draft of a blog post, a quick regex, and a summary of a long PDF without switching context. The free tier is generous enough for casual use, and the paid tier adds meaningfully faster responses and more capable models.
