Readability Scorer

Analyze text readability using industry-standard formulas. Get grade level estimates, complexity metrics, and suggestions for improving clarity.

Quick Start

from scripts.readability_scorer import ReadabilityScorer

# Score text
scorer = ReadabilityScorer()
scores = scorer.analyze("Your text to analyze goes here.")
print(f"Grade Level: {scores['grade_level']}")
print(f"Flesch Reading Ease: {scores['flesch_reading_ease']}")

Features

• Multiple Formulas : Flesch-Kincaid, Gunning Fog, SMOG, Coleman-Liau, ARI
• Grade Level : US grade level estimate
• Reading Ease : 0-100 ease score
• Text Statistics : Words, sentences, syllables, complex words
• Batch Analysis : Process multiple documents
• Comparison : Compare readability across texts

Individual Scores

# Get specific scores
fre = scorer.flesch_reading_ease(text)
fkg = scorer.flesch_kincaid_grade(text)
fog = scorer.gunning_fog(text)
smog = scorer.smog_index(text)

Batch Analysis

texts = [text1, text2, text3]
results = scorer.analyze_batch(texts)

# From files
results = scorer.analyze_files(["doc1.txt", "doc2.txt"])

Comparison

# Compare two texts
comparison = scorer.compare(text1, text2)
print(f"Text 1 grade: {comparison['text1']['grade_level']}")
print(f"Text 2 grade: {comparison['text2']['grade_level']}")

CLI Usage

# Analyze text
python readability_scorer.py --text "Your text here"

# Analyze file
python readability_scorer.py --input document.txt

# Compare files
python readability_scorer.py --compare doc1.txt doc2.txt

# Batch analyze directory
python readability_scorer.py --input-dir ./docs --output report.csv

# Specific formula only
python readability_scorer.py --input doc.txt --formula flesch

Examples

Analyze Blog Post

scorer = ReadabilityScorer()

blog_post = """
Writing clear content is essential for engaging readers.
Short sentences help. Simple words work best.
Your audience will thank you for making things easy to understand.
"""

scores = scorer.analyze(blog_post)
print(f"Flesch Reading Ease: {scores['flesch_reading_ease']:.1f}")
print(f"Grade Level: {scores['grade_level']:.1f}")
print(f"Reading Time: {scores['reading_time_minutes']:.1f} minutes")

if scores['grade_level'] > 8:
    print("Consider simplifying for a wider audience.")

Compare Document Versions

scorer = ReadabilityScorer()

original = open("original.txt").read()
simplified = open("simplified.txt").read()

comparison = scorer.compare(original, simplified)

print("Original:")
print(f"  Grade Level: {comparison['text1']['grade_level']:.1f}")
print(f"  Flesch Ease: {comparison['text1']['flesch_reading_ease']:.1f}")

print("\nSimplified:")
print(f"  Grade Level: {comparison['text2']['grade_level']:.1f}")
print(f"  Flesch Ease: {comparison['text2']['flesch_reading_ease']:.1f}")

improvement = comparison['text1']['grade_level'] - comparison['text2']['grade_level']
print(f"\nImprovement: {improvement:.1f} grade levels easier")

Batch Analyze Documentation

scorer = ReadabilityScorer()
import os

results = []
for filename in os.listdir("./docs"):
    if filename.endswith(".md"):
        text = open(f"./docs/{filename}").read()
        scores = scorer.analyze(text)
        results.append({
            'file': filename,
            'grade': scores['grade_level'],
            'ease': scores['flesch_reading_ease']
        })

# Sort by difficulty
results.sort(key=lambda x: x['grade'], reverse=True)

print("Documents by Difficulty:")
for r in results:
    print(f"  {r['file']}: Grade {r['grade']:.1f}")

Dependencies

nltk>=3.8.0

Limitations

• English language only
• Formulas designed for prose (may not work well for lists, code, etc.)
• Syllable counting is estimated (may have minor inaccuracies)
• Doesn't assess comprehension, only surface-level complexity
