Claritar vs Content Checker

Claritar is web-based brand voice software for agencies. It evaluates drafts against saved client voices, identifies off-brand content, and supplies rewrites. Users provide 5–10 on-brand pieces; Claritar infers tone, rules, banned words, and keywords from them. Each draft receives a 0–100 score and an A–F grade, with separate breakdowns for voice, tone, banned words, and keywords. Tone controls cover formal or casual, serious or playful, and a target reading level. Teams can define preferred terms, acronyms, product names, punctuation preferences, banned words, and required keywords. Review features include score gates, approve-or-return flows, writer scorecards, and an approval audit trail. Claritar can crawl a sitemap, score pages against a saved voice, rank pages that diverge, and export one audit report. It supports multiple languages, PDF reports, shareable links, and Agency-plan white-labeling. Content is encrypted in transit and at rest, access is scoped to team members, and drafts are used only for scoring and rewriting.

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.
