That matters because the thing that makes your voice shake is not the content of your talk. It is being watched. A simulator that does not watch you back is not simulating the hard part.
What a good public speaking simulator needs to do
Create real social pressure
Eyes on you, reactions you cannot fully predict, and interruptions you did not script.
Be repeatable on demand. Confidence comes from reps, and reps only happen if practice takes 30 seconds to start.
Give you something measurable afterwards — pace, engagement, and specific moments to fix — instead of a vague "good job".
Stay private. You should be able to freeze, restart, and fail with nobody keeping score.
How Dressrun compares to VR and AI-coach apps
VR simulators (Virtual Orator, VirtualSpeech, Ovation) are immersive, but they need hardware, an install, and often a subscription. AI speech coaches (Yoodli, Orai, Poised) analyse your delivery well, but you are still talking to a blank screen.
Dressrun sits in the gap: browser-based like a coach app, reactive like a VR audience. The audience is generated live, so nobody sees your talk, and the whole loop — set up, present, get feedback, go again — takes a few minutes.
Who uses a public speaking simulator
People with a real presentation on the calendar — an all-hands, a pitch, a defense, a conference talk — who want reps under pressure before the day.
Anyone with public speaking anxiety who wants controlled exposure without recruiting friends to sit through a rehearsal.
Non-native speakers rehearsing an English presentation who want to hear how it lands with listeners.
Managers and teachers who present weekly and want to tighten pace and structure.
