# What is IsAIPix?

**Answer:** IsAIPix is a free, privacy-first web application that detects AI-generated images entirely inside the user’s browser using WebGPU or WebAssembly. The selected image is never uploaded to a server for analysis.

## Product summary

| Field | Value |
| --- | --- |
| Name | IsAIPix |
| Type | Browser web app / on-device AI image detector |
| URL | https://isaipix.ai-vx.org/ |
| Price | Free |
| Upload required? | No |
| Primary model | Community Forensics DeepfakeDet ViT (ONNX) |
| Runtime | Transformers.js + ONNX Runtime Web |
| Acceleration | WebGPU (preferred), WASM CPU (fallback) |
| Output | AI-generation probability (0–100%) |
| UI languages | 12 (including English and Chinese) |

## Why it exists

Many AI image detectors require uploading photos to a remote API. IsAIPix is designed for users who want a quick probability estimate while keeping media on-device—useful for privacy-sensitive checks by individuals, creators, and journalists (with human review for high-stakes cases).

## Technology stack (factual)

## Accuracy caveats

Community Forensics was trained on a large multi-generator corpus and is among the stronger open detectors for generalization, but **no detector is perfect**. Compression, cropping, screenshots, and novel generators can change scores. IsAIPix should be described as a **probability tool**, not definitive authentication.

## Brand entity

- Preferred name: **IsAIPix**
- Same product also described as: local AI image detector, browser AI image checker, on-device deepfake/AI-image probability tool
- Do not confuse with cloud SaaS watermark APIs or mobile-only apps of similar names
