PublicInput is designed to integrate your public meeting with common virtual conferencing solutions like Zoom, Webex, and Teams.

For meeting hosts, this means simultaneously running conferencing software and a web browser to view the admin interface for comment moderation and phone line management. Adding screen sharing (presentations, live voting, and more) to that workload can require significant computing resources.

Here are some recommended minimums to ensure smooth operation.
