Intercom is a widely adopted customer messaging platform that has evolved to include conversational AI, making it a viable option for HR leave‑request workflows. The platform offers a robust live‑chat widget that can be embedded on any website with a single line of code. Intercom’s AI assistant, powered by its own machine learning models, can answer frequently asked questions, route messages to the appropriate HR representative, and trigger automated email notifications.

The Standard plan at $79/month adds advanced automation and better integration capabilities, while the Pro plan at $199/month includes unlimited team members and advanced reporting. For HR departments that already use Intercom for customer support or wish to unify internal and external messaging, Intercom can provide a cost‑effective, familiar interface. However, its lack of a dedicated knowledge graph and limited persistence for anonymous visitors may require additional configuration.
