How to Detect AI Generated Text & Analyze Writing Probability
AI text models generate language by calculating highest-probability next words. This creates distinct writing fingerprints: uniform sentence lengths (low burstiness), predictable vocabulary (low perplexity), and reliance on specific RLHF clichés ('delve into', 'vibrant tapestry', 'testament to'). Our client-side AI Text Detector highlights these exact markers in real-time.
See the Difference Before & After Cleaning
Hidden artifacts and zero-width characters cause unexpected layout shifts, regex crashes, and AI detector flags. Here is how clean text compares.
In today's fast-paced world, artificial intelligence serves as a testament to human innovation. Furthermore, delving into this digital realm allows us to foster pivotal advancements.
AI Probability: 92% | Human Score: 8% | 3 Clichés Highlighted
Technical Character & Feature Breakdown
Our browser engine detects and strips non-printable unicode points, LLM clichés, and metadata streams automatically.
| Character / Flag Name | Identifier / Sample | Impact & Behavior |
|---|---|---|
| Sentence Perplexity Variance | Perplexity Score | Evaluates word choice unpredictability. Low variance indicates automated LLM sampling. |
| Burstiness Monotony | Sentence Length | Measures sentence length distribution across paragraphs. AI text exhibits uniform sentence counts. |
| AI Cliché Phrase Density | Delve, Tapestry, Realm | Flags overused RLHF training phrases (delve, tapestry, testament to, furthermore). |
| Passive AI Structure | is / was + verb + by | Identifies formal passive voice patterns common in automated AI drafts. |

Your questions, answered
Got questions about zero-width characters, AI detection probability, or privacy? We have answers.
How does this AI Text Detector work?
Our AI Text Detector analyzes string perplexity, sentence length variance (burstiness), and overused AI cliché phrases (delve, tapestry, realm, testament to) to compute a Human vs AI probability percentage.
Is my text saved or uploaded to cloud servers?
No! Processing runs 100% locally in your browser memory. Zero text is logged, uploaded, or stored.
Which AI models can this detector identify?
It detects structural writing patterns characteristic of ChatGPT (GPT-3.5/GPT-4o), Claude 3.5 Sonnet, Google Gemini, Microsoft Copilot, and open-source LLMs.
Can I humanize detected AI text with one click?
Yes. Click 'Humanize & Copy Text' to strip robotic clichés and restore natural human sentence variation.
