To write a book with AI, start by brainstorming your book idea using AI tools like ChatGPT or similar chatbots to generate concepts and themes. Next, create an outline with AI's help to organize chapters and key points logically. Then, use an AI writing assistant (such as Novelcrafter, Copy AI, or WriteSonic) to draft sections of your book, generating text based on your outline. Importantly, review and edit the AI-generated content to infuse your own voice and ensure emotional depth. Finally, use AI for additional tasks like research, formatting, and polishing the manuscript before publishing. Combining specialized longform AI tools with chatbots offers the best results for structure and narrative quality.
