How it works

  1. 1Paste any proposal text, draft section, or executive summary.
  2. 2Read your Flesch Reading Ease, Flesch-Kincaid grade, and Gunning Fog scores.
  3. 3Cut the flagged jargon, shorten the longest sentences, and rerun. Target ≤10th grade.

Why it matters

The federal Plain Writing Act of 2010 requires agencies to write clearly — and most evaluators apply the same standard to proposals. Texts above 10th-grade level are perceived as evasive, even when the content is strong.

Three formulas together — Flesch Reading Ease, Flesch-Kincaid Grade, and Gunning Fog — triangulate readability in seconds. The free OptiRFP tool flags the same jargon list the full editor blocks at write time.
