AI Checker — Free AI Content Detection Tool

Check text, images and video for signs of AI generation. Each result is a probability score with a plain-language verdict and a breakdown — a signal to weigh, not proof.

AI Detection for Text, Images and Video

One workspace holds three AI detectors and two writing tools. Check text for signs of AI writing, images for AI generation, and video clips for AI generation, or switch to the plagiarism and grammar checkers without leaving the page.

AI Text Detection

Paste 300+ words to get an AI-likelihood score with the sentences that drove it highlighted. It looks for statistical patterns common to language models; it can be wrong.

AI Image Detection

Upload an image for an AI-generation probability from a third-party model, plus a separate score for signs of face manipulation.

AI Video & Deepfake Detection

Upload a clip up to 50 MB for an AI-generation probability with ML, OCR and metadata sub-signals. It is not a dedicated deepfake detector.
