AI chatbots have exploded in popularity over the past couple of years, and for good reason. They’re changing how we work, learn, and even entertain ourselves. But when it comes to choosing the right one, two names always come up: Character AI and ChatGPT.
In this article, I’ll break down their key differences, best features, pros and cons, and pricing. I’ll also answer a common question I often hear: does Character AI use OpenAI?
What Is Character AI?
Character AI is a chatbot platform designed around the idea of having conversations with personalities, not just an AI assistant. Instead of getting straightforward answers to questions, you interact with bots that are built to mimic different characters.
This includes historical figures, fictional heroes, or a personality you design yourself. I’ve used it for brainstorming creative story ideas, practicing dialogues, and even just light-hearted roleplay when I wanted a break from work.
One of the most common questions people ask is: does Character AI use OpenAI? The answer is no, Character AI was developed by former Google engineers and runs on its own large language models. That means the way it responds, and the style of conversations you get, feel very different from ChatGPT.
What Is ChatGPT?
ChatGPT, on the other hand, is an AI chatbot built by OpenAI and powered by one of the most widely known large language models. Unlike Character AI, which is designed around personalities and roleplay, ChatGPT is built for practical conversations: answering questions, explaining concepts, drafting emails, summarising documents, or even generating code.
