Finally, an InDesign grammar checker!
MindGrammar 4.0 is a fully integrated grammar checker for Adobe InDesign and Adobe InCopy. Currently MindGrammar is available for InDesign and InCopy CS3-CC 2026.
Version 4.0 adds a new Comma error category and over 500 new grammar rules across the existing categories, now organized into two groups, Grammar Errors and Grammar Info, so you can focus on real errors and surface lighter style suggestions only when you want them.
On the Mac, MindGrammar 4.0 integrates Apple's Natural Language engine for sharper, context-aware checking with fewer false positives, and introduces Writing Tools powered by Apple Intelligence — Proofread and Rewrite your text right from the MindGrammar dialog (requires macOS 15.2 or later on Apple Silicon).
A new Story Statistics panel reports words, sentences, syllables, and reading level at a glance.
It provides simple, yet powerful, grammar checking support for the English language.
Improve your writing and eliminate grammatical errors when editing your InDesign documents.
MindGrammar 3.0 adds a new MindGrammar grammar check dialog to easily walk through all text in your InDesign document and check for grammar errors.
MindGrammar 3.0 saves no additional data to your InDesign document. So if you are working on a indd document in a shared workflow, you no longer have to worry about other users having the MindEnabler compatability plugin.
For dynamic grammar checking, or grammar checking as you type, please see our MindGrammar Pro 4.0 plugin.
