Copresent

Overview

Copresent is a lightweight browser extension that lets teammates seamlessly control and co-present Google Slides from any device without screen-share swaps or app installs. It turns any smartphone into a swipe-to-advance mobile remote while keeping real-time speaker notes synchronized across all presenters. Supporting up to 10 co-presenters on a single deck, it eliminates awkward handoffs during webinars, client pitches, and lectures. The platform is private by design, keeping all presentations securely within Google Slides.

Founder story

Copresent was built to solve the awkwardness of remote and in-person team presentations where speakers waste time swapping screen-shares or shouting 'next slide, please.' The creators designed a frictionless browser extension that lets multiple presenters control a single Google Slides deck using only a shared link and their mobile phones.
