I ve been building a tool for creators lately and I noticed something frustrating: almost every web-based teleprompter suffers from micro-lags when you use a phone as a remote. This happens because the data has to travel to a server and back to your screen.
It might not seem like much, but in a professional recording, a 1-second delay ruins the flow.
I decided to use P2P (WebRTC) technology to connect the devices directly. No middleman, no lag.
PromptNinja is a privacy-first web teleprompter that solves the biggest pain point in video production: server lag. By using Peer-to-Peer (WebRTC) technology, it syncs your smartphone and computer directly, ensuring a buttery-smooth scroll without delays. Built as a PWA, it requires no installation and features a specialized "Musician Mode" for lyrics and chords. Perfect for YouTube creators, Zoom presenters, and live performers who need professional-grade stability.
