Rilevatore di filigrane AI

SynthID is Google DeepMind's invisible watermarking technology that embeds imperceptible patterns into AI-generated images from Imagen and Gemini. It's designed to survive common modifications like cropping, compression, and filters. Our detector analyzes DCT (Discrete Cosine Transform) coefficients and frequency patterns to identify these signatures.

Yes! Stability AI embeds "Stable Signature" watermarks in images generated through their official API. Our tool detects these signatures by analyzing latent space patterns, VAE (Variational Autoencoder) artifacts, and channel correlations unique to Stable Diffusion outputs.

GLAZE and Nightshade are tools developed by University of Chicago researchers that add adversarial perturbations to images. These subtle changes protect artwork from being used to train AI models while remaining mostly invisible to humans. Our detector identifies these patterns through high-frequency analysis and gradient uniformity tests.

Detection accuracy depends on the watermark type and image quality. SynthID and Stable Signature are designed to be robust and are generally detectable. However, heavy image manipulation may degrade watermarks. Our confidence scores indicate detection certainty - higher scores = more confident detection.

Yes! Our Invisible Watermark Detector is completely free to use with no limits. Upload any image and get instant detection results for SynthID, Stable Signature, GLAZE/Nightshade, and steganography.

Yes! Nano Banana is a Google AI image generation model that automatically embeds SynthID watermarks in all generated images. Our detector can identify images created by Nano Banana by analyzing the SynthID invisible watermark patterns. This helps verify if an image was generated by Google's Nano Banana AI model.
