Analyze My Writing vs ApyHub Readability Scores Documents 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.

ApyHub Readability Scores Documents API scores documents and publicly accessible web pages, returning a readability score, reading level, and text statistics. File requests accept PDF, DOC, or DOCX uploads up to 100 MB. English checks use the Flesch Reading Ease formula by default, while German uses the Wiener Sachtextformel. Results can include word, sentence, character, and paragraph counts, average lengths, and estimated reading and speaking times. The score includes a grade class, a plain-language label, and an indication of whether a standard readability threshold is met. ApyHub lists uses such as reviewing contracts, policies, manuals, help pages, websites, reports, and proposals; AI agents can also access the API through ApyHub MCP for content reviews. The product page offers five API calls a day free without a card. Starter is free and includes 3,000 atoms per month; Pro costs $16 a month and Pro+ $42 a month. Requests can return a 429 rate_limited error when the plan's per-second limit is exceeded.
