Most "free" online tools make you pay with your files: upload to a server, create an account, hit a daily cap, and export with a watermark anyway. ClearPix is different by architecture, not by policy. Every AI model runs **locally in your browser** via ONNX Runtime Web (WebGPU, WASM fallback) — your files are never uploaded, there is nothing to sign up for, and exports carry no watermark.
