Readability Scorer
Content & CreativeTestedContent readability analysis — Flesch, Flesch-Kincaid, Gunning Fog, SMOG, Coleman-Liau, passive voice detection.
Readability Scorer analyzes any webpage or text for reading difficulty using five standardized indexes: Flesch Reading Ease, Flesch-Kincaid Grade Level, Gunning Fog, SMOG, and Coleman-Liau. It also detects passive voice usage, finds the hardest sentences in your content, and generates actionable recommendations for improvement.
Ask about your content's reading level, grade difficulty, or writing quality. Agentcy fetches the page, strips the HTML, and runs the full readability analysis — returning scores, grade levels, and specific sentences that are dragging down readability.
This is an always-available bundled service — no setup required. Analyzes any public URL or you can describe specific text.
