One Platform for the Entire Book
For years, authors have had to cobble together messy software stacks—using Microsoft Word or Google Docs to write, Scrivener to organize, external AI tools to edit, and separate design software for book covers, formatting, and publishing.
Storyloft is built from the ground up as a modern, unified book writing app that supports the entire author lifecycle. Research, outlining, manuscript writing, AI editing, illustration, cover design, ebook creation, print formatting, and publishing tools stay connected inside the same book project.
For research-heavy books: See how Storyloft compares directly with Zotero and Scrivener for source management, manuscript research, citations, notes, long-form organization, and nonfiction writing.
For indie publishing: Discover why modern writers are moving their entire indie author software stack to Storyloft to write, edit, illustrate, format, design, and publish books in one secure workspace.
Replace a scattered writing stack with one connected platform. Your manuscript, research, notes, AI context, citations, visuals, formatting, and publishing tools remain together from the first idea through the finished book.
One connected book writing platform for research, outlining, manuscript writing, AI editing, illustration, cover design, formatting, ebooks, print books, and publishing.

Find quick answers to common questions about Storyloft's writing platform for authors.
Yes. Storyloft provides a best-in-class manuscript editor built for authors, so you can draft, revise, and organize long-form writing with confidence.
With Storyloft’s editor, you can control page layout and formatting preferences, work in a distraction-friendly writing environment, and keep essential tools close at hand. It includes built-in side panels for notes, comments, and history so you can track changes, collaborate thoughtfully, and make iterative improvements faster—all within a smooth, author-first workflow.
If you want faster drafts and sharper revisions without losing your author voice, yes—Storyloft includes an AI writing assistant designed for manuscript work. You can ask for feedback, brainstorming, and targeted improvements, then apply results directly to your manuscript so you’re not stuck copy/pasting between tools.
If you struggle with turning suggestions into real edits, Storyloft streamlines that gap. The platform supports AI-assisted editing flows where the output can be inserted into your document as structured content—so you can move from “idea” to “edit” quickly and keep momentum.
If you’re worried AI will sound generic or inconsistent, Storyloft is built around your writing style. It supports voice-aware rewrites that aim to preserve your tone and preferences, helping you revise while keeping your manuscript’s personality intact.
If you need reliable references while you write, Storyloft’s research assistance is designed for authors who want sources they can use. It supports research-oriented workflows (including citation/source handling) so you can go from question → evidence → revision without leaving your writing session.
If you want your book to feel organized—not just “stuff written down”—Storyloft helps you manage structure. You can work with manuscript sections and maintain an organized workflow so drafting, revising, and refining happens in a way that supports long-form storytelling.
If you want your manuscript to come alive with visuals, Storyloft includes dedicated illustration workflows. You can generate and manage illustration sets tied to your project—making it easier to plan, produce, and iterate on visuals that match your story.
If you don’t nail the look on the first try (most authors don’t), Storyloft supports iterative improvement. You can revisit generated outputs and refine them so the final visuals match your intended characters, tone, and style.
The best book writing app for authors should do more than provide a blank page. Storyloft combines AI-powered editing, outlining, notes, goal tracking, illustration tools, and professional print and ebook formatting in one platform designed specifically for writing books.

If you’re serious about finishing, Storyloft supports publishing-oriented outputs. You can use export flows designed for manuscript-to-publication transitions—so your work can move from draft to shareable formats efficiently. We support ready-to-print paperback manuscripts and publishable ebook format for platforms like Kindle and more. Formats include Docx, Ebook (epub), and print-ready PDFs.
If you often lose track of sources, ideas, and references during revision, Storyloft’s notes and citation workflows keep those artifacts attached to your writing process. That means fewer “where did I read that?” moments and a smoother revision loop.
If momentum matters, Storyloft includes writing progress tracking features like goals, streaks, and stats. This turns drafting into a system you can maintain, not something you restart every time you get stuck.
If typography and presentation are part of the experience you want, Storyloft lets you tailor the reading/work environment. You can adjust themes and layout-related settings so the editing experience matches your aesthetic and workflow.
