Claritar vs Hemingway Editor

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.

Hemingway Editor scores writing for readability and highlights sentences and issues that may weaken or complicate a message. Editor Plus adds rewriting for wordy sentences and passive voice, grammar fixes, and controls for tone, length and style. It also provides document review with writing feedback and suggestions, and supports importing and exporting Word, Markdown and HTML files. The Classic desktop app works offline and keeps writing on the computer; it can publish to WordPress or export HTML and Markdown for a blogging platform or CMS. Hemingway Editor is available on web, macOS and Windows. The free plan is available. Individual 5K annual access costs $8.33 a month, billed as 100 USD annually, and includes 5,000 AI sentences per month. Hemingway Editor 3 desktop costs $19.99, paid once and does not include new AI features. Hemingway says document content is discarded after processing and is not used to train AI models. For analysis or rewriting, content is sent through Hemingway to an LLM provider, currently OpenAI, Google or Anthropic, and then discarded. Editor Plus does not yet have SOC 2 or ISO certification.
