- Paste Your Text — Enter or paste the text you want to improve. The tool works best with essays, blog posts, emails, reports, and any prose content of at least 2 sentences.
- Review Suggestions — Click Analyze to see your Flesch readability score and a prioritized list of improvements. Each suggestion is color-coded by severity (red = high priority, amber = medium, indigo = low) with the specific issue, fix recommendation, and the affected text.
- Apply and Re-Analyze — Edit your text based on the suggestions, then click Analyze again to see your improved score. Repeat until you reach your target readability level. Copy the improvement report for reference.
About the Readability Improver
WritePadPro's Readability Improver goes beyond scoring — it gives you specific, actionable suggestions to make your text clearer and more readable. While our Readability Checker tells you your Flesch score is 42 (college level), this tool tells you exactly what to change to bring it up to 65 (general audience).
Six Types of Suggestions
- Long Sentences — Identifies sentences over 25 words (medium priority) and over 30 words (high priority). Suggests splitting them into shorter sentences. Research shows readers lose comprehension after 25 words in a sentence.
- Complex Words — Contains a database of 90+ complex words mapped to simpler alternatives. "Utilize" becomes "use," "facilitate" becomes "help," "approximately" becomes "about." Each suggestion shows the exact replacement word.
- Passive Voice — Detects passive constructions like "was written by" and suggests active voice rewrites. Identifies the passive verb pattern and recommends making the actor the subject of the sentence.
- Long Paragraphs — Flags paragraphs with 6+ sentences. Online readers prefer 3-4 sentences per paragraph. The tool suggests where to add paragraph breaks.
- Adverb Overuse — Counts filler adverbs (very, really, actually, basically, literally, etc.) and flags when they exceed 3% of total words. Suggests using stronger verbs instead.
- Repetitive Sentence Starts — Detects when 3+ sentences begin with the same word, creating monotonous rhythm. Suggests varying sentence openings.
Priority Levels
Each suggestion is categorized by severity: High (red) for issues that significantly hurt readability (very long sentences), Medium (amber) for moderate issues (passive voice, long paragraphs), and Low (indigo) for style improvements (complex words, adverbs). This helps you focus on the highest-impact changes first.
Iterative Improvement
The tool is designed for an iterative workflow: analyze your text, make changes based on the top suggestions, then re-analyze to see your improved score. Each round should raise your Flesch score. The goal is not to eliminate all suggestions — some complex words are necessary for precision, and some sentences need length for nuance. The goal is to address the highest-priority issues until your score reaches your target level.
Sample Text
The default sample text is intentionally written with poor readability: excessive passive voice, complex words that have simpler alternatives, long sentences, and filler adverbs. This lets you see the tool in action immediately — generating a long list of suggestions that demonstrate every detection category.
Privacy
All analysis uses client-side JavaScript: regex patterns for passive voice, a static word database for complexity, and arithmetic for readability scoring. Your text never leaves your browser. No external API, no server processing, no data collection.
Frequently Asked Questions
How is this different from the Readability Checker?
The Readability Checker SCORES your text with 6 formulas (Flesch, Gunning Fog, etc.) and tells you the grade level. This Readability Improver tells you HOW TO FIX specific issues: which sentences to split, which words to simplify, where passive voice exists, and which paragraphs are too long. The Checker diagnoses, the Improver prescribes.
What kinds of issues does it detect?
Six categories: (1) Long sentences over 25 words that should be split, (2) Complex words that have simpler alternatives (e.g., "utilize" to "use"), (3) Passive voice constructions that should be rewritten in active voice, (4) Long paragraphs with 6+ sentences that should be broken up, (5) Overuse of filler adverbs like "very", "really", "actually", and (6) Repetitive sentence openings where multiple sentences start with the same word.
How many complex words does it know?
The tool contains a database of 90+ complex words mapped to simpler alternatives. Examples: "utilize" to "use", "facilitate" to "help", "approximately" to "about", "demonstrate" to "show", "methodology" to "method", "necessitate" to "need", "remuneration" to "pay". Each suggestion shows the exact simpler word to use.
What is a good Flesch readability score?
For web content, aim for 60-70 (8th-9th grade level). For general audience blog posts, 70-80 (7th grade) is ideal. For academic writing, 30-50 (college level) is acceptable. For children's content, 90+ (5th grade). The tool shows your current score with a visual bar and grade level, so you can track improvement as you edit.
Does it use AI to generate suggestions?
No. The tool uses rule-based analysis: regex patterns for passive voice detection, a curated word complexity database for simplification suggestions, word counting for sentence length, and string matching for repeated sentence starts. No AI, no API, no machine learning. This means it is 100% predictable, transparent, and private.
Is my text sent to a server?
No. All analysis runs in your browser using JavaScript. Your text is never transmitted to any server. The complexity database, passive voice patterns, and readability formulas are all embedded in the client-side code.
