Free AI detector and ChatGPT checker — no sign-up. Paste text to check if it was AI-generated and get an AI probability score with sentence-level signals.

Most detectors only read text. AI or Not covers five formats and shows its work: a sentence-level heatmap for writing, the likely generator for an image, temporal-flicker and face-warp signals for video, synthetic-timbre cues for a cloned voice, looping artifacts for AI music. It catches deepfakes and voice clones — not just fully AI-made media — and keeps pace as Sora 2, Veo 3, and Suno ship. Paste up to 500,000 characters or upload a file free, no account needed.
