| Privacy | ApyHub says it does not log API request or response bodies and retains API call metadata logs for 90 days. | The tool runs entirely in the browser, and text is processed on the user’s device rather than uploaded by DO101. |
| Purpose | Scores documents and web pages for readability and returns a score, reading level, and text statistics. | The checker measures text readability with six published formulas and sentence rhythm analysis. |
| Support | ApyHub lists a Discord community, email, live chat with agents, and a 24/7 AI assistant as support channels. | Support is handled through a Gmail address with best-effort replies from a small project rather than a staffed help desk. |

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.
