Open is a unified AI customer support platform built around Agent 5, a single AI engine shared across every channel and designed to automate and unify support. It brings AI Chat, AI Calls, AI Email, AI Social, Agentic Workflows, and helpdesk integrations into one system so customer conversations can be handled consistently across web chat, phone, email, Instagram, Messenger, WhatsApp, SMS, and existing support tools. Agent 5 goes beyond simple FAQs by handling complex requests, processing returns, updating accounts, coordinating multi-step workflows, routing issues, remembering conversation history, and handing off smoothly to human agents when needed. Web Chat can be embedded with one line of code, customized to match the brand, triggered proactively based on user behavior, and enriched with images, videos, files, links, buttons, forms, cards, and carousels.
