JavaScript VS Storyloft

Storyloft's answer:

Storyloft is an all-in-one AI book writing app that keeps the whole book in one manuscript, from first draft to print-ready files. Most AI writing tools generate text for you. Storyloft's AI editor, Eddy, reads the entire manuscript along with its worldbuilding and research, then gives developmental and line feedback shaped by the author's own voice. Nothing changes until the author accepts it, and manuscripts are never used to train AI.

In one app, Storyloft combines:

• Eddy, a manuscript-aware AI editor that follows a voice profile built from the author's own prose
• A World Builder for characters, places, factions, timelines and lore, connected to the draft
• Research Mode for nonfiction, with sourced reports, Fact Cards and managed footnotes and endnotes
• AI book illustration that keeps characters consistent across scenes, plus a print and ebook cover designer with ISBN barcodes
• Automatic print-ready PDF and EPUB formatting for Amazon KDP and IngramSpark, plus DOCX export
• Web, macOS and Windows apps, so Windows authors can format print books without a Mac

Because everything works from the same manuscript, a late revision flows straight through to the final print and ebook files.

Storyloft's answer:

Choose Storyloft if you want one app for the whole book instead of a stack of separate tools.

• Compared with AI fiction tools like Sudowrite: Storyloft supports nonfiction as well as fiction, edits your writing rather than generating it, and also formats print-ready PDF and EPUB files on web, macOS and Windows.
• Compared with Scrivener: Storyloft adds a built-in AI editor, worldbuilding, AI illustration, a cover designer and book themes that produce print-ready files, so there's no separate compile-and-format step.
• Compared with Vellum or Atticus: you write, edit and format in the same app, and Storyloft runs on Windows as well as macOS, while Vellum is Mac-only.
• Compared with ChatGPT: Eddy works from your whole manuscript, lore and research instead of pasted excerpts, follows your voice profile, and never uses your manuscript to train AI.

You can try the full workflow on the free plan, which covers your first 5,000 words with no credit card. Storyloft Pro is $39/month or $398/year, and Lifetime Access is a one-time $399.

Storyloft's answer:

Storyloft is built for indie and self-publishing authors writing fiction or nonfiction who want to draft, AI-edit, format and publish a book in one app.

• Novelists and series writers who need worldbuilding, lore and continuity across books
• Nonfiction authors, including memoir, biography, self-help, business and narrative nonfiction, who need sourced research, citations, footnotes and charts
• Authors of illustrated and children's books who need consistent characters and print-ready covers
• Co-authors and editors who want to work in the same manuscript with comments, version history and role permissions

Storyloft is not built for writers who want AI to generate whole books, need a native phone app, or write short-form or marketing copy.

Storyloft's answer:

Storyloft was founded by Pierce Brantley, a product manager and developer by background and an author himself.

He started Storyloft because the tools authors depend on hadn't meaningfully changed in a decade, and writing a book still meant juggling separate apps: Word or Scrivener for drafting, ChatGPT for feedback, Canva for covers, and Vellum or Atticus for formatting. Every handoff meant exporting, reformatting and losing context.

The idea was simple: one workspace for the whole book, with the manuscript as the single source of truth. Edits flow through to the print and ebook files, the AI editor knows the characters and the research, and illustrations come from the story itself.

From the start, Storyloft took a clear position on AI: it should help authors write better books, not write the books for them. That's why Eddy edits and advises instead of generating chapters, why every suggestion waits for the author's approval, why AI can be switched off, and why manuscripts are never used to train AI models.

Storyloft's answer:

Storyloft is a cloud-based web app with desktop apps for macOS and Windows. At a high level:

• Writing app: a React web app built for long-form manuscripts, with real-time collaborative editing
• AI editing: large language models accessed through tuned models whose terms don't allow training on customer content, combined with retrieval-augmented generation (vector search) so Eddy can work across long manuscripts, lore and research
• Illustration: image-generation models guided by saved character references and art styles
• Research: connections to scholarly, archival and web sources, with each citation tracked from source to endnote
• Publishing: a typesetting pipeline that produces print-ready PDF, EPUB and DOCX files
• Infrastructure: cloud hosting behind a global CDN
