ChatGPT Plus is one of the most powerful chatbots available. It offers a wide range of features, uses some of OpenAI's most advanced language models, and includes extra tools that are especially useful for writers.
The main drawback is similar to most other chatbots - it blocks certain NSFW content. If you write erotica or highly gory scenes, you may need a different tool.
I've found that many GPT models don’t produce the most readable prose. The writing can be overly fancy, wordy, or dramatic. Some updates, like the 11-20-2024 GPT-4o "creative writing update," have improved this. However, I think other chatbots, such as Claude or Gemini, are still better than ChatGPT's GPT models for creative writing.
