Full name: “Copyrule: Style Guide & Consistency Checker”
$15 a month or $159 a year per Google account. Free trial: 15 documents or 14 days, whichever comes first. No card needed.
Copyrule checks every Google Doc against your house style and fixes what breaks it. Your preferred terms and banned words, how product names are written, how numbers, dates, times and money look, punctuation, heading case, abbreviations and legal wording: one rule set, shared with the whole team as a single file, applied the same way for every writer. No AI, and nothing about your documents leaves Google.
Your house style, as rules
What you get
- Your house style as rules: preferred terms and banned words with replacements, product names with exact capitals and a ® or ™ on first mention
- Choices for spelling (US, UK, Oxford), numbers, dates, times, currency, percent, units, serial comma, quotes, dashes, ranges, ellipses and heading case
- Abbreviations defined on first use, legal defined terms checked, required phrases such as disclaimers
- Presets to start from: news (AP-like), book and academic (Chicago-like), government plain language, legal drafting
- One shared rule file in Drive for the whole team, reloaded whenever the editor changes it; or paste JSON or CSV
- Consistency across the document: e-mail and email, Internet and internet, colour and color, 3 and three
- Fix one, fix a group, or fix all with a preview; ignore with a reason; highlights by category that restore your own colors
- A compliance summary to paste into the review ticket
- Only opens the Doc you use it in and rule files you pick; no AI, nothing leaves Google
