Could you build this?
Partial Creating a standard textarea wrapper is easy, but integrating a WebGPU custom AI lexer model and the bleeding-edge Chrome OpaqueRange API requires deep shader/browser-internals knowledge.
What it would actually take: The project requires a lightweight neural network (27.4 KB) compiled to run inference directly in the browser via WebGPU shaders (WGSL), tokenizing syntax on the fly. The rendering relies on experimental Chromium APIs (OpaqueRange) to paint highlight ranges directly within native DOM textarea elements without syncing a mirror div. Building this requires specialized expertise in WebGPU compute shaders, ML model quantization/compilation for the web, and deep knowledge of experimental browser rendering APIs.
