Analyze My Writing vs ATOS Analyzer

Analyze My Writing is a free web-based analyzer for text content and readability. It counts words, sentences, characters, punctuation, and word or sentence lengths. The service lists common words, two-word and three-word phrases, and a word cloud. Readability results include Gunning Fog, Flesch-Kincaid, SMOG, Coleman-Liau, and Automated Readability indices, plus Fry and Raygor graphs. It calculates lexical density, shows parts of speech and tagged sentences, and highlights words that can indicate passive voice. Cloze tests can remove every nth word, selected words, or a random percentage; selected-word mode requires fewer than 5,000 characters. The Free plan costs nothing, needs no registration, and allows unlimited texts, with length limited by the browser and system. Submitted text is not saved, and no cookies or third-party cookie code are used. Log files may include technical visit details. Users must be at least 18.

ATOS Analyzer is a free web tool for estimating the readability level of text and books in English or Spanish. Users can enter a passage, analyze an entire book, or submit a sample with an estimated word count. Text can be typed or uploaded as a .txt, .docx, or .epub file, with uploads limited to 10 MB. The suggested passage length is 150 to 25,000 characters. Results include an ATOS level, grade-level equivalent, word count, AR Points, average word length, average sentence length, and language. ATOS estimates complexity on a grade-level scale using sentence length, word length, and word difficulty; its measure also accounts for book length. For a sampled book, Renaissance recommends three passages of about 150 words from different parts and an estimated total word count. Scanned documents need OCR to become recognized text before submission; changing a file extension does not convert them. The page includes a CCSS/ATOS grade-band chart for grades 1 through 12. Renaissance presents the measure as guidance for matching students with appropriately leveled reading material.
