I find ChatGPT extremely useful for language related tasks - especially as non-native English speaker - it helps me find the most appropriate phrasing in terms of tone, style and conciseness, and it is better in translating longer text from non-English languages (like Korean) than any other tool I ever had experience with. ChatGPT is also a convenient alternative to casual googling, e.g. when I need to find a quick answer on a topic widely covered across various reliable sources such as encyclopaedias, ChatGPT makes it very easy to find an answer on a specific question I may have. However, ChatGPT is currently unreliable for professional level research because it can hardly provide specific sources of the information it provides.
