Entangled Text
Entangled Text is a fiction-first AI novel writing studio for authors who want real help drafting a book without handing the book over. You outline a story, draft chapters with your approval at every step, revise with clear side-by-side diffs, and export a finished manuscript as EPUB, DOCX, PDF, Markdown or TXT — formatted for Amazon Kindle Direct Publishing.
Most AI writing tools are chat windows that forget the book overnight, and novels fail for exactly that reason: context disappears after a few thousand words, so chapter forty stops matching chapter four. Entangled Text is built around long-form structure instead — story bibles, genre presets, chapter queues, revision history, continuity checks, and chapter locks that hold an approved passage in place when later chapters are regenerated. Work saves between sessions on every plan.

OneKDP
OneKDP is a browser-based workspace for independent authors and self-publishers preparing books for Amazon Kindle Direct Publishing (KDP). It combines AI-assisted book and cover creation with editable interiors, a cover editor, KDP-oriented sizing and preflight tools, and separate exports for interior and cover files. It supports novels, nonfiction, workbooks, coloring and puzzle books, journals, and planners. Generated text and artwork can be revised before export. The service also provides publishing calculators and author tools for book details, descriptions, royalties, print costs, cover dimensions, and promotional copy. Manual tools and editing are available on a free plan; AI generation uses credits, while paid subscription plans add monthly credits and keyword research. Users review exported files and upload them through their own KDP accounts; OneKDP does not publish books automatically.
