Lean Publishing Tip of the Day 💡 Our New AI Cover Designer #AIbookcover #bookcover #coverdesign

Leanpub added an AI cover designer that generates book cover images from a user-written description directly in the Settings section of its publishing workflow. The feature automatically handles Leanpub's cover image technical specifications, and Leanpub co-founder Len used it on his first try to create a cover for the Demo Livestream book, then applied it to the book landing page with one button click. Leanpub said the tool follows earlier AI-assisted features such as generating social media images from an existing cover.

It might seem like a small thing, but a really magical thing happening here, is that you don’t have to know anything about our cover image technical specifications. It’s all just handled for you automatically.

Here’s an example Len created, the first time he used the feature, for the Demo Livestream book:

…and here’s what it looked like on the book landing page, when Len clicked the button to use the new cover image:
