Show HN: Voice-tracked teleprompter using on-device ASR in the browser
lbaune Sunday, March 15, 2026
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.

Most 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.
