Why does every web teleprompter have lag? (And how I solved it)

Hi everyone! I’m Ken.

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.

My question to the community: For those who record video content or give live presentations—what is the 'small' technical friction that bothers you the most? Is it lag, setup time, or something else?

I'm launching my solution, PromptNinja, tomorrow and would love to hear your thoughts on this!
