In their own words
ApyHub Readability Scores Documents API
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.
Hemingway Editor
Hemingway Editor scores writing for readability and highlights sentences and issues that may weaken or complicate a message. Editor Plus adds rewriting for wordy sentences and passive voice, grammar fixes, and controls for tone, length and style. It also provides document review with writing feedback and suggestions, and supports importing and exporting Word, Markdown and HTML files. The Classic desktop app works offline and keeps writing on the computer; it can publish to WordPress or export HTML and Markdown for a blogging platform or CMS. Hemingway Editor is available on web, macOS and Windows. The free plan is available. Individual 5K annual access costs $8.33 a month, billed as 100 USD annually, and includes 5,000 AI sentences per month. Hemingway Editor 3 desktop costs $19.99, paid once and does not include new AI features. Hemingway says document content is discarded after processing and is not used to train AI models. For analysis or rewriting, content is sent through Hemingway to an LLM provider, currently OpenAI, Google or Anthropic, and then discarded. Editor Plus does not yet have SOC 2 or ISO certification.
