House Style lets you define preferred terms and review every match in context. Apply a replacement deliberately, with the original draft retained in revision history before the edited document saves. HOW TO USE THE UPGRADE 1. Open House Style from the editor toolbar. Manage rules, add a literal term and an optional preferred replacement, and save the guide. 2. Review the current draft. Inspect each match and its context, then choose individual replacements. 3. Revisit revision history when needed. Export a guide as JSON or import one with confirmation; guide files do not include the draft. The editor, local prose analysis, document library, word echoes and revision tools remain available. Echo detection no longer depends on optional part-of-speech model availability. WHAT TO KNOW Up to 50 literal rules and a 200 KB draft for House Style. More than 499 matches blocks the whole review instead of presenting partial results. Matching can respect word boundaries and case; it does not understand meaning, verify facts or establish a legal style standard. Replacements require an unchanged draft and a successful document save. Existing revision-history limits apply. iPhone and iPad. No account required.
