Flesch-Kincaid Grade Level
Higher Flesch Reading Ease = easier to read (60–70 is considered "plain English," ideal for most web content). Grade Level estimates the US school grade needed to understand the text. Syllable counting uses a standard vowel-group heuristic (like most free readability tools) — expect it to be off by one on some irregular words, but accurate on average across a full paragraph.
