Show HN: PhantomLoop – Real-time BCI decoder visualization in the browser

a Web-based dashboard for real-time brain–computer interface research. It connects to a backend via WebSocket, streams neural data (142 channels @ 40Hz), runs decoders (JavaScript or TensorFlow.js), and visualizes ground truth vs predictions live.

The goal is to make it easy to prototype and compare neural decoders with immediate feedback. You can bring your own decoders, or even generate one directly in the app via a prompt.

Still experimental / WIP
