How this service works
Deterministic readability scores (Flesch, Flesch-Kincaid, Gunning Fog, SMOG, Coleman-Liau, ARI) over published formulas. For long text use POST. Signed.
Output
A JSON object containing multiple readability scores (Flesch reading ease, Flesch-Kincaid grade level, Gunning Fog, SMOG, Coleman-Liau, ARI), text counts (words, sentences, syllables), estimated reading time in seconds, and the scoring method used — all computed deterministically from published formulas.
Example use cases
Grade-level check for patient materials
“I just drafted this patient discharge summary and I need to make sure it's written at or below an 8th grade reading level before we send it out. Can you run all six readability scores on it — Flesch, Flesch-Kincaid, Gunning Fog, SMOG, Coleman-Liau, and ARI — so I know if it needs to be simplified?”
Editorial review for news articles
“We have a house style rule that all our public-facing news articles should hit a Flesch Reading Ease of at least 60. Can you score this draft article across all the standard readability indexes so I can see where it lands and whether the editor needs to simplify the language?”
Compliance check for legal disclosures
“Our legal team needs to verify that this terms-of-service document meets plain-language compliance requirements before it goes live. Can you calculate the full set of readability metrics — Flesch, Flesch-Kincaid, Gunning Fog, SMOG, Coleman-Liau, and ARI — and tell me what grade level it's effectively written at?”

Side effects

- Empty string input may produce undefined or zero scores
- Extremely short text (1-2 words) may yield unreliable or extreme scores
- Text with no sentence-ending punctuation may miscalculate sentence counts
- Non-English text may produce inaccurate syllable counts and scores
