Transparent, Rule-Backed Writing & Readability Analysis
Clear, error-free writing builds immediate credibility with readers and search engines alike. PursTech's AI Writing Tools combine rule-based linguistic inspection with classic computational readability formulas so writers, students, and editors can polish drafts without hitting paywalls or word-count caps.
Our Grammar Checker evaluates up to 20,000 characters at a time against more than 6,000 grammar, spelling, punctuation, and style rules powered by LanguageTool, paired with client-side scanners for passive voice constructions, adverb overuse, sentence-length variance, and overall tone. Every flagged issue is color-coded by category with one-click replacements and a downloadable proofreading report.
To ensure your writing matches your target audience's reading level, our Readability Checker computes seven industry-standard indices simultaneously—Flesch Reading Ease, Flesch-Kincaid Grade Level, Gunning Fog Index, SMOG Index, Coleman-Liau Index, Automated Readability Index (ARI), and Linsear Write—highlighting complex multi-syllable words and long sentences in real time.
