Your ai detector report and analysis will appear here.
Inspect Writing for Statistical AI Markers
Fast, deterministic linguistic analysis evaluating perplexity, sentence structure entropy, and repetitive syntactic patterns.
How to use AI Detector
Provide Text
Paste a minimum of 50 characters to ensure sufficient sample size for statistical pattern analysis.
Automated Inspection
The engine parses vocabulary distributions, ngram repetition, and sentence length variance instantly.
Review Results
Examine overall AI probability score alongside sentence-level breakdowns and pattern highlights.
Key Capabilities
Perplexity & Burstiness Metrics
Evaluates word choice predictability alongside the rhythm and variance of consecutive sentence lengths.
Deterministic Scoring Engine
Runs fast local heuristics without routing your private draft to third-party language models for scoring.
Sentence-Level Highlights
Identifies individual sentences that exhibit high predictability or rigid syntactic repetition.
Private Analysis & Security
Your text is analyzed in isolated runtime workers and never indexed into public training datasets.
Frequently Asked Questions
How does this AI detector work?
The tool analyzes statistical properties of writing including perplexity (how expected words are) and burstiness (how much sentence structure and length vary throughout the text).
Are AI detectors 100% accurate?
No AI detector is infallible. False positives can occur on structured human writing, and false negatives can occur on edited machine text. These scores should be used as guidance rather than definitive proof.
Why is there a 50-character minimum?
Statistical analysis requires sufficient text to calculate reliable variance in vocabulary and sentence structures.
Does the AI detector store my text?
Submissions are recorded temporarily to manage your session job history and rate limits in accordance with our privacy policy, but your content is never sold, shared with third parties, or used to train public AI models.
