Storyloft

Storyloft is a web book writing app combining a manuscript editor, the Eddy AI editor, research and citations, worldbuilding, illustration, cover design and print and ebook formatting in one project for fiction and nonfiction authors.

Storyloft is a web-based book writing app that tries to hold the whole production chain of a book in one project. Instead of drafting in a word processor, organizing in a separate manuscript tool, asking a general chatbot for feedback and then moving files into formatting software, an author keeps the manuscript, research, notes, worldbuilding, artwork, covers and final files together. It is aimed at both fiction and nonfiction writers, including beginners, and at authors who publish traditionally or independently. The writing environment is a long-form manuscript editor with chapters, notes, writing goals and a Focus Mode. Beside it sits Eddy, an AI assistant that reads the manuscript, its structure and the author's voice before responding. Eddy gives developmental feedback on plot, character arcs, arguments, pacing and continuity, and it can investigate a topic, check a claim or suggest sources. Saved sources, citations, footnotes and endnotes stay attached to the passages they support, which matters for research-heavy nonfiction such as biography, true crime, philosophy and self-help. Fiction writers get a structured worldbuilding space for characters, locations, factions, magic systems, timelines and relationships, which Eddy can draw on as canon. An illustration tool creates reusable characters and scenes in a consistent book-specific style, and a cover studio handles the jacket. When the draft is ready, automatic formatting produces a paginated print PDF and an EPUB 3 ebook, with controls for trim size, margins, gutters, bleed, running headers and front and back matter. Within the market, Storyloft positions itself as an alternative to the Scrivener plus Google Docs plus Zotero plus formatting-tool stack, and publishes comparison pages against those and against Vellum and Atticus. The tradeoff of that breadth is that each module competes with a specialist product. A set of free planning, page count and metadata utilities, plus a 5,000 word free tier, lets writers test the workflow before paying.
