Paltalk is a video group chat service that enables users to communicate via video, internet chat and voice. It offers chat rooms and the ability for users to create their own public virtual chat room. Paltalk is available in three formats: Paltalk Messenger, the regular version most users use, Paltalk Mobile, (iPhone, Android) the phone version, and Paltalk Express which is a Flash version of the software targeted at non-Windows users. It is proprietary software. While basic services are free of charge and basic software is free to download, fee-based memberships and paid upgrades to more capable paid versions are offered by AVM Software, the creators of Paltalk.
