Youbooks is a new AI book author that combines popular AI models such as ChatGPT, Claude and Gemini to help you create complete nonfiction books. A lifetime subscription is on sale now for just $49 (regularly $540).
How does Youbooks AI write your book?
If you’ve ever tried to write anything longer than a few hundred words using ChatGPT, you know how disjointed the AI can be with long text. The AI Writing Tools in Apple Intelligence probably won’t knock your socks off, either.
Youbooks does things differently. The AI book author uses multiple models to create nuanced, coherent manuscripts up to 300,000 words long. This leaves plenty of room for you to dive into the gritty grit of your chosen niche.
Research is an important part of nonfiction writing, and Youbooks can help with that, too. The built-in research tool pulls up-to-date facts and statistics to keep your content up-to-date.
You can also upload your own research, documents and transcripts. The AI book writer then incorporates everything into the manuscript to make the result more tailored and fact-based.
Adjust your tone and writing style
With Youbooks, you can fully customize your tone and writing style. Whether you want an academic voice, a conversational tone, or something in between, AI Book Writer can handle it. You can even save up to 100 sample styles to help shape future projects.
For creators concerned about rights, Youbooks offers another key benefit: You retain full commercial ownership. This means you can publish, distribute, or sell your book however you want without additional royalties or royalties.
The lifetime contract includes 150,000 monthly credits, covering writing output as well as recorded source material. You’ll also get access to upcoming feature updates.
And when it’s time to deliver, Youbooks lets you download documents in DOCX, EPUB, PDF, and Markdown formats.
