This text analysis tool runs entirely in your browser, computing readability scores (Flesch-Kincaid Grade Level, Flesch Reading Ease, Gunning Fog, SMOG, Coleman-Liau, and ARI), keyword density, type-token ratio, reading time estimates, and detailed character, word, sentence, and paragraph counts — all in real time as you type or paste. Because the analysis happens locally with no server round-trip, your drafts, client copy, medical notes, or any sensitive text stay on your device and are never uploaded anywhere. Drag and drop a .txt, .md, or .rtf file to get started immediately, and export the full results as JSON or your text as Markdown when you are done.
- Content & SEO WritersCheck keyword density and Flesch Reading Ease to ensure copy hits the right grade level and avoids over-stuffing before publishing.
- Academics & StudentsVerify a paper or essay meets readability and complexity requirements without pasting text into an external service.
- UX & Product TeamsMeasure lexical diversity (type-token ratio) and sentence complexity in UI copy to keep microcopy clear and consistent.
- Editors & ProofreadersGet an instant Gunning Fog or SMOG score to flag overly complex passages and prioritise where to simplify.
- Privacy-Conscious ProfessionalsAnalyse legal, medical, or confidential documents without any risk of data leaving the browser — no upload, no account required.
