Delimiter Readability Checker vs TextGears

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.

TextGears checks writing for spelling, grammar, style, and readability, through its website and API. The API also provides autocorrection, text analysis, language detection, summarization, and keyword extraction, returning JSON through HTTP or HTTPS requests. Its documentation lists 11 languages, including English, French, German, Portuguese, Russian, Italian, Arabic, Spanish, Japanese, Chinese, and Greek, as well as dialect codes such as en-US, en-GB, and pt-BR. A Postman collection and JavaScript library link are available for integration. Free access includes 500 requests per month, 200k characters per month, and a 4k-character request limit. PRO costs $2.48 a month and includes unlimited checks, translations, and paraphrases of long texts, custom dictionary rules, and an option not to store texts. TextGears says AI does not support every language and recommends standard plans when language breadth matters more than AI analysis quality. Readability metrics are recommended for texts of at least 30 words. The maker is headquartered in Tallinn, Estonia.
