Text analysis
AI Text Detector
Paste a text sample below to estimate whether it was generated by AI. The panel on the right will display live results from the API: score, decision and signals.
Your text will be analyzed for statistical patterns such as paragraph length variance, vocabulary diversity, and repetition ratios.

How to read the result
Understanding the score, decision and signals
Every analysis is probabilistic. The goal is to show where the signal comes from, not to issue a binary verdict about your text.
Final score & decision
The score is a value between 0 and 1. Higher means more AI‑like according to the model. The decision label ("Human‑like", "AI‑generated", "Uncertain"…) is just a human‑friendly summary of that range.
Source breakdown
The Metadata part reflects signals from external hints such as known generator tags, watermarks or C2PA manifests (if available). The Model part comes from purely textual patterns: sentence structure, word choice, rhythm and other statistics.
Features & metrics
The Features (raw) section lists numeric metrics used by the model: sentence length distribution, lexical diversity, repetition levels, punctuation patterns and more. They are useful for inspection and debugging rather than as standalone proof.
