Highlight any sentence, open Refine, and Revise shows you a cleaner version of your own line; Proofread catches the slips you stop seeing after the tenth read. It's not writing the book for you — it's showing you the fix so you start catching it yourself. Every tool here is optional, and Settings › AI Configuration › AI features switches any of them off.
Revise
Open the Refine panel and switch to Revise to rework a scene across six dimensions: voice, tone, diction, syntax, figurative language, and structural style. Choose meaning-preserving, continuity-preserving, or suggestions-only modes, and review every change in a side-by-side diff before applying.
Line Edit
The Line Edit tool in the Refine panel makes sentence-level refinements — clarity, rhythm, diction. Each micro-edit is shown individually so you can accept or reject changes one at a time.
Expand
In the Refine panel, Expand develops thin scenes with AI-generated prose that follows your established beats. Review the expanded text in a side-by-side diff before applying.
Dialogue
Dialogue has its own toolbar button because it works at the chapter level, not the scene. It reads dialogue across an entire chapter to judge character-voice consistency and groups its suggestions by character. Because it spans the chapter, its results stay put as you move between scenes.
Your style profile
The first time you run a style-conditioned operation, Bookshaper extracts a style profile from your manuscript — your characteristic patterns of diction, syntax, and tone — and uses it to condition Revise, Line Edit, Expand, Dialogue, and the proofread style pass, so suggestions follow your established voice instead of generic editorial defaults. There is nothing to set up and no profile to manage: it is generated automatically and kept as conditioning input. What you do see is a note on each new result saying whether it was styled to your voice or produced generically — and, when generic, why (no API key configured, a read-only account, or a profile that couldn’t be generated).
Undo and redo
Every applied refinement is tracked in a history stack. Undo and redo refine operations at any time without affecting your regular editing history.
Three layers in one panel
Spelling and grammar run locally and instantly — they work offline and spend no credits. The grammar layer covers passive voice, readability, repeated words, a/an usage, sentence spacing, quotes, and contractions. Style analysis catches craft-level patterns: show-don’t-tell, clichés, purple prose, filter words, adverb overuse, dialogue tags, sentence variety, head-hopping, punctuation, homophones, and capitalization. When a style profile exists, suggestions are calibrated to your prose, so patterns consistent with your established voice aren’t flagged.
Working the list
Issues appear as inline wavy underlines colored by severity — errors, warnings, suggestions. Click an issue to scroll and highlight the passage in the editor, or click a marker in the editor to find its issue in the panel. Apply one-click fixes with suggested replacement text, dismiss individual issues, or ignore an entire rule category. Matching handles curly quotes, em-dashes, and other typographic characters.
Flags
Flags marks the page as you write: names that sit close together, repetition in this chapter, runs of sentences that open the same way, and spelling on this page. It runs on your machine and nothing is sent anywhere.
Actions
My Actions is your revision worklist, kept beside the draft under Actions. It holds only what you put there: a finding or an Editorial Read suggestion arrives when you press Add To My Actions, and nothing is added for you.
