A second pair of eyes on your manuscript: structural feedback and a grammar and spelling check, both shown right where the issue is.
The Critique tab reads your whole manuscript and gives you two things: a structural analysis that flags common craft issues (the kind an editor would circle in the margin), and a full grammar and spelling check across every chapter. Both come back as a single, organized list you can work through, and both can be highlighted directly inside your manuscript so you never lose track of where an issue actually is.

Each finding comes with a short explanation and, where useful, a suggestion, never an automatic rewrite. You stay in full control of your own words.
Click "Check Grammar" to run a full pass for spelling mistakes, grammar issues, and common style slips across your entire manuscript, in addition to the structural critique.
Every book keeps its own dictionary: a list of words the spell checker will always treat as correct. It is where character names, place names, invented terms, brand names and technical vocabulary belong, so they stop being flagged on every run. The dictionary is per book, so one novel's invented vocabulary never leaks into another project.
There are two ways to add a word:
The Dictionary panel also shows everything currently in the list, with a × on each word to remove it, so a word added by mistake is easy to take back. New words apply the next time you run a check.
If your book isn't in US English, set the correct language and dialect for your project (UK, Canadian, and Australian English, plus several other languages) from the Critique tab before running the check. This keeps spelling and grammar suggestions aligned with the conventions you're actually writing in, instead of flagging normal spellings as mistakes.
Turn on "Findings" from inside Write or Flow mode's toolbar and every finding lights up directly in your text, color-coded by type. Click a highlight to see the full explanation, and dismiss any finding you've reviewed and decided not to act on: dismissed findings won't reappear until you run a fresh check.
Prefer to work through edits on paper? "Print" on the Critique tab lays out every open finding, chapter by chapter in book order, each with the passage it points to, what was found, and a suggestion, plus a small box to tick off as you go. Your print dialog opens on its own, and you can save it as a PDF from there instead.
Export a version of your manuscript with every finding preserved as a real comment in the file: useful for reviewing offline, sharing with a beta reader, or working through issues away from the editor.
