Youbooks is an AI generation platform for nonfiction book creation, with the core goal of turning users' ideas and materials into complete, publishable manuscripts.
In terms of use: it mainly serves authors, entrepreneurs, and professionals who want to quickly produce nonfiction books, as well as teams and publishers with regular publishing needs. The platform accepts not only short ideas starting from scratch, but also supports in-depth writing based on existing research materials.
Main capabilities:
- Long-form generation: can generate manuscripts of up to 300,000 words, with each project executing more than 1,000 AI steps, covering deep research, ideation, multiple rounds of writing, and editing.
- Source-driven: supports uploading PDF, DOCX, TXT, or directly pasting text, so that each chapter is grounded in the materials provided by the user; users can also choose to let the platform search the web to supplement background.
- Voice training (Human model): users can provide 20,000 to 200,000 words of writing samples (such as articles, books, or transcripts), and the platform will fine-tune an exclusive model to imitate their tone, rhythm, vocabulary, and structure; if personalization is not needed, the editor's default style can be used.
- Generation and export: set the topic, audience, length, and chapter depth, enable consistency control, then generate chapters, support inline review, and export with one click to DOCX, EPUB, Markdown, or RTF.
- Privacy and copyright: files remain private, and users retain full rights to their content and trained voices.
How to use:
- Optionally upload materials; if no materials are provided, draft directly from the brief description.
- Optionally train a Human model; the editor's default style can also be used.
- Set the book's scope and depth, enable consistency and coherence checks, then review and export after generation.
- The first draft can be completed in a few hours, but the platform emphasizes that a complete project requires several days of continuous computation.
