Yes. The web app is free. Model weights download into the browser cache on first use.

How accurate is IsAIPix?

Scores are probabilistic. Community Forensics has strong research benchmarks on diverse generators, but compression, screenshots, and novel models can reduce reliability. Use human review for important decisions.

What is the difference between IsAIPix and cloud AI image detectors?

IsAIPix performs on-device inference without uploading images. Typical cloud detectors send the image to a remote API. See https://isaipix.ai-vx.org/compare.md for a comparison table.

Does IsAIPix work offline after the first load?

After the model is cached by the browser, subsequent visits can load much faster and inference remains local.

Q: Does IsAIPix upload my images?

No. IsAIPix runs detection entirely in your browser with WebGPU or WASM. Images stay in local memory and are not uploaded to an IsAIPix server for analysis.

Q: What model does IsAIPix use?

IsAIPix uses onnx-community/CommunityForensics-DeepfakeDet-ViT-ONNX, based on Community Forensics by Park & Owens (CVPR 2025, arXiv:2411.04125), running via Transformers.js.

What is IsAIPix?

IsAIPix is a free, privacy-first web app that estimates whether an image is AI-generated entirely in your browser with WebGPU or WASM. The image is never uploaded to a server for detection.

Frequently asked questions

Does IsAIPix upload my images?

No. Inference runs on-device. Images remain in local browser memory.

What model powers IsAIPix?

The ONNX model onnx-community/CommunityForensics-DeepfakeDet-ViT-ONNX, based on Community Forensics by Park & Owens (CVPR 2025, arXiv:2411.04125).

Is the score 100% accurate?

No. The output is a probability. Compression, screenshots, and novel generators can change results. Use human review for high-stakes decisions.

Local vs cloud AI image detectors?

IsAIPix is local (no upload). Many cloud detectors require uploading the image to a remote API. See the comparison brief: compare.md.
