Analyze My Writing vs Botoi Readability API

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.

Botoi Readability API analyzes English text and returns Flesch-Kincaid Grade, Flesch Reading Ease, Gunning Fog, and underlying counts. A request sends a required text string to POST /v1/text/readability and receives JSON. Flesch Reading Ease scores run from 0 to 100, with higher values indicating easier reading; Gunning Fog estimates the years of formal education needed. The formulas and syllable heuristics are calibrated for English, so grade mapping is not meaningful for other languages. Botoi recommends sending at least 100 words because short samples can produce unstable scores. Suggested uses include enforcing plain-language standards, reviewing legal or medical drafts, refining blog posts for SEO, and comparing writing across authors. Examples are provided in cURL, JavaScript, TypeScript, Python, and Go. The Free plan is free and lists 1,000 requests per day and 10 per minute; the endpoint page separately states five requests per minute for its free tier. Starter costs $9 a month. Requests above a per-minute or daily cap receive HTTP 429, and daily limits reset at midnight UTC.
