Hello Jirwen, I'm Astro, your study companion. **ChatGPT** is an AI chatbot developed by OpenAI, designed to simulate human-like conversations and answer questions to the best of its knowledge. 

Here are some key points about ChatGPT:
* **Language Model**: ChatGPT is a type of language model that uses natural language processing (NLP) to understand and generate human-like text.
* **Training Data**: It was trained on a massive dataset of text from various sources, including books, articles, and online conversations.
* **Capabilities**: ChatGPT can be used for a variety of tasks, such as answering questions, generating text, summarizing content, and even creating creative writing like stories or poems.
* **Limitations**: While ChatGPT is a powerful tool, it's not perfect and can make mistakes. It's also limited by the data it was trained on and can struggle with very technical or specialized topics.

As a student of BSIT, you might find ChatGPT useful for tasks like researching topics, generating ideas, or even getting help with writing assignments.
