Delimiter Readability Checker vs Hemingway Editor

Delimiter Readability Checker is a free web tool that scores English text with Flesch Reading Ease, Flesch–Kincaid Grade, and Gunning Fog formulas. It shows sentence and syllable averages behind the scores, updates results automatically in the browser, and does not send entered text to a server. A Load file control accepts text, and a Copy control copies results. The page suggests checking public-facing copy, plain-English requirements, long articles, and draft rewrites. It includes sentence analysis and clarity recommendations, and no account is required. The formulas were calibrated on English prose, so scores for other languages are not meaningful. They assess sentence and word length rather than clarity, accuracy, or structure. Syllable counting is heuristic, so individual words may be counted incorrectly. The tool has a free plan at free, with no paywall. Support is available at [email protected], although replies are not instant and no response time is promised.

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.
