Everything you need to publish your book is in this bundle.
All you need in addition is a subscription to Midjourney. (Basic plan starts at $10 a month)
Note: The course teaches techniques using ChatGPT which has both free and paid versions. You can use the free alternative Claude.ai
You will also need to upscale your cover images. Topaz Gigapixel is the best tool currently available but there are many free alternatives. We like upscayl.org.
