ThriveDesk is a custom service solution that provides a unified inbox, chat bot, and knowledge base along with a number of other features. Today you can use it with many different platforms, but because it started with WordPress there are a lot of WordPress integrations. These include WooCommerce, SureCart, Easy Digital Downloads, Freemius, FluentCRM, FunnelKit, SureTriggers, and FlowMattic. ThriveDesk is an alternative to onsite help desk plugins. The LTD pricing is still available.
