NativeX

Author prompt graphs, wire them together with {{var}}, and run them on the exact hardware your app ships on. Every run executes on the Apple foundation model that ships with your device — no account, no API key, no server. Nothing leaves the device.

NativeX is a visual playground and evaluation bench for Apple's on-device Foundation Models: build prompt pipelines as a graph of cards, run native OCR / speech / language ops, and trace every step — all on-device, at zero token cost.
