Understanding Metrics

This tool measures how easy your writing is to read. Here's what each score means.

The Key Numbers

Metric What It Tells You
Grade Level School grade needed to understand
Reading Ease Comfort level (0-100, higher = easier)
ARI Another grade measure, based on characters
Fog Index Years of schooling needed

Quick Rule

For most docs, aim for grade 10-14 and ease above 30.

What's a Good Score?

Your Audience Target Grade Target Ease
Everyone 6-8 60-70
High schoolers 9-12 50-60
Tech workers 12-14 30-50
Experts only 14+ Under 30

How to Improve

Bad scores usually mean:

  • Sentences are too long
  • Words have too many syllables
  • Writing is passive instead of active

Fix it by:

  1. Break long sentences into shorter ones
  2. Use simple words (say "use" not "utilize")
  3. Write "the API returns data" not "data is returned"
