Content Checker vs Trinka

Content Checker helps writers apply Government Digital Service style guidance and content design rules to text. It checks for words to avoid, capitalisation, spelling, formatting, and inclusive language against over 140 rules. A searchable GOV.UK A-to-Z style guide is included, and a setting can add HMRC-specific rules and entries. The website can suggest URL slugs from page titles using GOV.UK URL standards and show changes made by each rule. The free app works offline and is available on Android, iOS, and macOS; the web version is also available. Editor support is listed for web, iOS, and macOS. The maker says app checks happen on the device without sending content to a server. Website submissions are sent for processing and immediately discarded; the maker says they are not stored, logged, or saved. Content Checker is independent and is not affiliated with or endorsed by GDS, GOV.UK, or HM Government.
