AI agent resolves issues before they escalate by combining omnichannel continuity, proactive intelligence and contextual memorySAN MATEO, Calif., April 30, 2025 /PRNewswire/ -- Sendbird Inc., the AI communications platform trusted by the world's largest apps, today announced the launch of its Omnipresent AI Agent, a smarter, more intuitive support solution designed to prevent customer service issues rather than just react to them. By combining omnichannel continuity, proactive insight and contextual memory, Sendbird's Omnipresent AI Agent introduces a new era of artificial intelligence-driven support – meeting customers wherever they prefer to engage across web, mobile, email, SMS, WhatsApp and voice channels – without losing track of the conversation history.As customers increasingly expect uninterrupted and personalized support experiences, companies are facing more pressure than ever to provide continuity across communications channels.

Unlike traditional tools that rely on static triggers or siloed interactions, Sendbird's AI agent remembers customer conversations to ensure support flows naturally, no matter where it begins."Customers don't think in terms of channels and neither should your AI.
