Chrome extension for the host
The host adds Copresent to Chrome once. Inside Google Slides, a button generates a unique link for the presentation session.
Copresent
Copresent is a Google Slides remote and shared-presenting tool for one host to install a Chrome extension and invite co-presenters by link.
Shared Google Slides control for co-presenters
Copresent is a shared Google Slides control tool for solo presenters and teams. It turns a phone into a slide remote and also lets multiple people drive the same deck from a link, which is useful when a presentation needs to move between speakers without screen-share handoffs or file swapping.
The product is built around Google Slides. One person installs a Chrome extension on the presenting computer, opens the deck, and shares a session link. Co-presenters then join from any browser on phone or desktop and take control of the slides when it is their turn.
Features
Phone-based slide control
The remote opens as a mobile-friendly web page, so a phone can act as the clicker without a separate app.
Speaker notes on every device
When someone is driving the deck, speaker notes appear on that device in real time.
Up to 10 co-presenters
A single session can support up to 10 co-presenters, letting multiple people take turns controlling the same deck.
Link-based team access
Co-presenters open a link in any browser and do not need an account, app, or install.
Deck stays in Google Slides
Copresent keeps slides inside Google Slides and uses a unique link for each session rather than copying the deck into another system.
Common use cases
Team pitches and read-outs
Run a sales or partner deck from Google Slides without passing screen-share control back and forth. The next presenter can open the same link and continue from the current slide with notes visible.
Classroom and project presentations
Give students, project teams, or panelists one shared presentation link so each person can present their section from a laptop or phone. This avoids re-sharing screens between speakers.
In-room teaching and workshops
Use a phone as the clicker while walking around a room. The presenter can advance slides, read notes, and stay away from the laptop during lectures, workshops, or onboarding sessions.
Online panels and webinars
Have remote co-hosts take turns inside the same deck during Zoom, Google Meet, or Teams calls. The audience still sees a normal screen share while presenters change control behind the scenes.
Board meetings and community sessions
Let board members or community groups open a link and take turns when it is their slot to speak. The setup keeps coordination simple because no one needs to create an account first.
