Storyloft
The argument for Storyloft is consolidation: manuscript, lore bible, covers and KDP-ready export in one workspace instead of four subscriptions. For a self-publishing author that is a real saving of both money and file-shuffling. The argument against is price - $39 a month is above Scrivener's one-time cost, though the $399 lifetime licence changes that maths for anyone writing a series, and the free tier's 5,000 words is barely two chapters, so you commit before you know how the editor handles your prose.
Pros
- Print-ready PDF and EPUB export with KDP margin handling built in
- Worldbuilding and lore organisation live alongside the manuscript
- Character illustration and cover generation included rather than bought separately
- Research mode with citation management
- Free tier needs no credit card, and a $399 lifetime licence is available
Cons
- $39/month is dearer than a one-time desktop writing app
- 5,000 free words is too little to evaluate a novel workflow
- Desktop builds are independently distributed, so macOS and Windows warn on first launch
- No company country published and no API
