I built a teleprompter that scrolls based on your voice instead of a timer.Paste a script, press record, and it highlights the current word as you speak. If you pause it waits; if you skip lines it finds its place again.Everything runs entirely in the browser — speech recognition (Moonshine ONNX), VAD, and fuzzy script matching.Demo: https://larsbaunwall.github.io/promptme-aiMost of the project was initially built using Perplexity Computer, which made for an interesting agentic coding workflow.Curious what people think about the script alignment approach.

Could you build this?
Yes It wraps an open-source pre-trained speech model (Moonshine ONNX) running in Transformers.js/WebAssembly with dynamic text alignment algorithms to scroll a script UI.
