Hi I’ve been using chatgpt to help write my book and lately ChatGPT has had issues with this. I have to constantly remind it to follow the instructions in my prompts. Some days it’s just so bad that I stopped at chapter 8. I have an extensive prompt and learning objectives. Is this something perplexity can handle better or is there something else that is recommended?

I would also like some recommendations to prompt when I’m writing so that it continues to read and follow all of the instructions.
