Free AI text detector
Paste English text and get a transparent AI-likeness score. Runs in your browser — nothing is uploaded.
Honest limit: This is a lightweight stylistic heuristic, not a trained detector like GPTZero, Originality.ai, or Turnitin. Scores are estimates for exploration and drafting checks — not academic or legal proof.

How this detector works
We score patterns that often show up in raw large-language-model drafts: even sentence rhythm, stock phrases (“delve into”, “it’s important to note”), dense formal transitions, and low vocabulary variety. Your text never leaves the device for analysis.
What it is not
It does not call paid AI APIs, store your content, or claim courtroom / school-board accuracy. For high-stakes decisions, use a dedicated commercial detector and human review.
