Paste a snippet to estimate whether it was written by AI or copied. Instant in-browser heuristics give you a likelihood score and the signals behind it — then get an optional AI second opinion.
Privacy: The heuristic score is computed entirely in your browser. The optional AI opinion uses Codeground's self-hosted model and is not stored.

There is no perfect way to prove a snippet came from an AI assistant — but generated and tutorial-copied code leaves fingerprints. This tool scores patterns like over-commenting, tutorial-style explanations, generic naming, docstrings on every function, and unusually uniform formatting. Use it as a signal during code review, academic integrity checks, or hiring screens — never as a sole verdict.
Is a high score proof of cheating? No. Treat it as one signal; well-written human code can score high, and AI code can score low.
Is my code uploaded? The heuristic score is local. Only the optional AI opinion sends the snippet to our self-hosted model, which does not store it.
