Text Readability Analyzer

Score how readable any text is — and learn exactly who can read it and how to make it clearer.

Live on the Apify Store — run it instantly, or call it as an agent tool via Apify MCP.

What you get

Six industry-standard formulas: Flesch Reading Ease, Flesch-Kincaid Grade, Gunning Fog, SMOG, Automated Readability Index (ARI), Coleman-Liau — plus a consensus grade level.
Reading level + target audience in plain language (e.g. "Standard — 8th–9th grade, the web sweet spot").
Actionable suggestions when the text is too complex (sentence length, complex words, word choice).
Full stats: sentences, words, syllables, characters, complex-word %, averages.
Single or bulk — analyze one text or up to 100 in a single run; each is scored independently.

No API keys, no setup. Pure analysis, runs in seconds.

Input

{
  "text": "Readability matters. Clear, concise writing reaches more people. Long, convoluted sentences crammed with multisyllabic terminology inevitably diminish comprehension."
}

Or score many at once:

{
  "texts": [
    "See Spot run. Run, Spot, run!",
    "The aforementioned phenomenological framework necessitates rigorous epistemological scrutiny."
  ],
  "maxTexts": 50
}

Output
