ChatGPT
ChatGPT is a historic conversational AI that sent shockwaves around the world upon its release in November 2022. Developed by OpenAI in the United States, its advanced natural language processing (NLP) technology enables it to handle a wide range of tasks, including human-like natural conversation, answering questions, text generation, code generation, translation, and brainstorming ideas.
By making AI technology, previously the domain of experts, accessible to anyone through an intuitive chat format, it accelerated the “democratization of AI.” It surpassed 1 million users in just five days after launch and recorded 100 million active users within two months. As the fastest-adopted application in history, it made a significant impact not only on the AI industry but on society as a whole.

ChatGPT: An Honest Practical Review
Strengths
As of 2026, ChatGPT stands out for its lightning-fast responsiveness—it truly feels like “every prompt gets an instant reply.” For everyday questions or simple text generation, answers come back in an instant, keeping the conversation flow perfectly smooth. Yet its ability to grasp your intent has evolved significantly since before. Even with vague requests, it proactively suggests, “Is this what you mean?”—a truly reassuring step forward. The latest model has also shed its tendency for overly verbose explanations, enabling natural, human-like interactions that feel like chatting with a close friend.
Points of Concern
While it's blazingly fast by default, switching to “Thinking Mode” for complex problem-solving is a different story. This mode involves the AI engaging in a thorough deliberation process behind the scenes, resulting in wait times reminiscent of its slower past. If you're used to its usual lightning-fast speed, this “thinking time” might feel a bit long. Also, while its conversational style is very natural and persuasive, it still occasionally slips in a “plausible lie” here and there. This habit hasn't been completely eliminated yet, so I make sure to double-check important information myself.
Overall Evaluation
ChatGPT is “the most reliable entry point for anyone wondering, ‘What even is AI?’” While many AI tools exist, starting with this one is a sure bet. Rather than just using it as a search replacement, try chatting casually with it like you would a friend. The old “mechanical coldness” is gone. It's lightning-fast most of the time and takes its time when things get tricky. As a dependable partner, the current ChatGPT feels like it's stepped up to a whole new level.
