Could you build this?
Partial The UI, sentence-level highlighting, and in-browser execution are straightforward to vibe-code, and a working prototype can wrap an existing open-source AI-text classifier running via WebAssembly or WebGPU. Reliable detection across current LLMs, however, depends on a well-trained classifier that the builder would have to source or create.
What it would actually take: The architecture is a static single-page app that runs a transformer classifier client-side (for example, a DistilRoBERTA-style model via transformers.js or ONNX Runtime Web), with a perplexity or burstiness pass per sentence for highlighting. The hard part is accuracy and calibration: a credible detector needs a large labeled corpus of human and multi-model AI text, periodic retraining as new models ship, and honest false-positive measurement, which requires ML research skills and compute. Fine-tuning and evaluation are the expertise gaps that vibe coding alone won't fill.
