One Connected Author Workspace

One manuscript. Every stage stays connected.

Storyloft is an all-in-one book writing app for authors. It combines a long-form manuscript editor, manuscript-aware AI, research and citations, worldbuilding, book illustration, professional formatting, cover design, and print and ebook publishing tools in one workspace.

Also built in: chapter organization, writing goals, comments, collaboration, version history, role permissions and project assets.

Long-Form Manuscript Editor

A writing workspace built for books.

A book is more than one very long document. Storyloft keeps chapters, sections, notes, comments, formatting, writing goals, and revision tools organized around the manuscript as it grows.

Stay organized across a full manuscript. Manage chapters and sections without losing sight of the whole book.
Keep supporting material close. Notes, research and comments stay available without taking over the writing space.
Make progress visible. Word goals, streaks and project progress help turn writing sessions into a finished manuscript.
Storyloft Long-Form Book Writing and Manuscript Editor Write and organize full-length books with chapters, manuscript navigation, notes, formatting, and author-focused writing tools.

Eddy AI Book Editor

AI that reads the manuscript, not just the prompt.

Eddy works inside the book with access to manuscript context, characters, research and your writing style. Ask for feedback, explore an idea, examine a passage or improve a weak section without moving your work into another chatbot.

Manuscript-aware feedback. Suggestions can account for the larger book instead of treating every passage as an isolated prompt.
Protect your writing voice. Voice-aware editing is designed to strengthen what you wrote without flattening it into generic AI prose.
You stay the author. Eddy helps you analyze, question, research and refine. You decide what belongs in the book.

Research, Sources & Citations

Research without leaving your book behind.

Keep research, sources, notes, citations and endnotes beside the manuscript. Eddy can help investigate a topic and surface source-backed information while the supporting material remains connected to the project.

Keep evidence with the manuscript. Research and reference material stay attached to the book instead of disappearing across browser tabs and separate apps.
Turn sources into usable citations. Citation and endnote workflows help move research from discovery into the finished manuscript.
Useful for fiction too. Historical context, locations, technology and other source material can be researched alongside creative work.
Storyloft Book Research, Sources, and Citation Tools Research topics, organize sources, create citations and endnotes, and keep supporting evidence connected to your manuscript.

Worldbuilding Software for Authors

Build the world inside the manuscript.

Storyloft World Builder connects characters, locations, factions, timelines, magic systems, technology and story canon directly to the book. Organize the details, map their relationships and keep them useful while you write.

Build structured lore. Create characters, places, factions, systems, histories, objects and rules that belong to the project.
See how everything connects. Relationship maps and visual views reveal connections across people, places, events and ideas.
Protect continuity. Storyloft can compare the manuscript with established lore and help surface details that may no longer agree.

Automatic Book Formatting

Make it look like a book before you export.

Professional book themes. Coordinate typography, headings and manuscript styling without rebuilding every chapter manually.
Real print geometry. Manage trim size, margins, gutters, page numbers, chapter starts and the details expected in a printed book.
Connected cover design. Create ebook and print covers while keeping the design tied to the actual dimensions of the book.
