Scrivener

Scrivener is writing software built specifically for long-form projects like novels, screenplays, and non-fiction books, rather than general-purpose word processing. It organizes a manuscript using a "ring-binder" metaphor with a corkboard and outliner for structuring chapters and scenes, alongside a dedicated research pane for keeping reference material next to the draft.

Ulysses

Ulysses is a writing app exclusive to Apple platforms, built for writers who manage long or multiple writing projects at once, from novels and articles to blog posts. It combines a distraction-free, markup-based editor with a library system for organizing texts into projects, along with writing goals and deadline tracking to keep longer works on schedule. Built-in grammar and style checking covers more than 20 languages, and finished work can be exported as PDFs, Word documents, ebooks, or published directly to WordPress, Ghost, Medium, and Micro.blog. Everything syncs seamlessly across Mac, iPad, and iPhone via iCloud, and the app has won an Apple Design Award for its interface and workflow.

Hemingway Editor

Hemingway Editor is a writing tool that color-codes sentences by readability, flagging overly complex or hard-to-read passages, passive voice, weakening adverbs, and better word choices as you type. The free web version works in any browser for quick edits, while the paid Editor Plus subscription adds AI-powered rewrite suggestions, grammar and plagiarism checks, and publishing to Medium or WordPress; a separate one-time Classic desktop app offers offline editing without AI features.

Sudowrite

Sudowrite is an AI writing assistant purpose-built for fiction, positioning itself as "the non-judgemental AI writing partner." Its Story Bible feature guides writers from an initial idea through outlining, chapter beats, and full drafts in their own voice, while tools like Write, Describe, Expand, and Rewrite handle different stages of prose generation and revision. The platform also includes a Feedback tool that surfaces actionable critique on a draft, a Canvas for visually planning plot points and character arcs, and a Visualize tool that generates character art from text descriptions. Plans start at $10/month for the Hobby & Student tier, scaling up to Professional and Max tiers for authors writing longer or more frequent works.
