Quick tip: Flesch-Kincaid Grade Level 8 is your target

Quick tip on writing docs and content: Flesch-Kincaid Grade Level 8 = readable by a 13-year-old. That's your target for most technical documentation. Not because your readers are 13 — but because shorter sentences and common words reduce cognitive load. Even senior engineers read faster at grade 8. Most enterprise docs sit at grade 14-16. That's why people skim them. The TextAnalytics API returns FK grade level (plus 4 other readability scores) in a single call: https://rapidapi.com/hummusonrails/api/textanalytics
