Readability Score
Calculate Flesch-Kincaid and other readability scores for your text content.
Flesch-Kincaid, Gunning Fog, SMOG, and Coleman-Liau all claim to measure how hard a text is to read, but they weigh different things to get there, syllables per word, sentence length, unfamiliar word count, which means they can genuinely disagree on the exact same passage, and that disagreement itself is informative: when every formula lands close together, the readability estimate is trustworthy, and when they scatter widely, the text probably has some unusual characteristic none of them individually captures well. This tool calculates Flesch-Kincaid alongside several other established readability formulas for the same text, rather than relying on one score in isolation.

Useful for cross-checking a readability estimate against more than one formula before trusting it, noticing when several scoring methods disagree in a way that flags something unusual about a text, or getting a fuller picture of a piece of writing's difficulty than any single formula would give alone.
