How UnAI.se Detects and Removes AI Writing Patterns

What is AI腔 (AI Writing Pattern)?

AI腔 refers to the stylistic fingerprints that AI writing models leave in text. These patterns include: uniform sentence length, filler words (furthermore, moreover, in conclusion), predictable transition structures, and lack of natural variation. UnAI.se detects these patterns across 5 dimensions and helps you humanize your content.

The 5 AI Detection Dimensions

UnAI.se analyzes text across 5 key dimensions: 1) Marker Words — stock phrases and filler language; 2) Transition Patterns — dense or predictable linking words; 3) Sentence Length Uniformity — limited rhythmic variation; 4) Pronoun Usage — repetitive or impersonal constructions; 5) Structural Regularity — rigid paragraph and section patterns.

How to Use This Free AI Detector

Step 1: Paste your text into the input area. Step 2: Click Analyze to detect AI patterns across 5 dimensions. Step 3: Review highlighted sentences and click to see rewrite suggestions. Step 4: Apply Light/Medium/Heavy rewrites or manually edit. Step 5: Copy your humanized text when your score drops below your target.

Important limitation

This tool identifies writing patterns; it cannot prove whether a person or an AI wrote a passage. Human writing can produce false positives. Use the result as an editing aid, not as the sole basis for academic, employment, or disciplinary decisions. Read the full methodology and limitations.

How to Reduce Your AI Writing Score

Click any highlighted sentence to see AI patterns detected. Use Light rewrite to replace individual words, Medium rewrite to adjust phrases, or Heavy rewrite for full sentence replacement. Add more natural variation in sentence length. Remove filler words and vary your transition structures.
