Samsung expands Galaxy AI with multi-agent ecosystem and ‘Hey Plex’ integration
Samsung Electronics Co., Ltd. has announced a further expansion of its Galaxy AI platform, signalling a deeper push into what it describes as an open, integrated multi-agent ecosystem designed to give users greater choice and flexibility in how they interact with artificial intelligence.
The update, announced in Accra on February 23, 2026, positions Galaxy AI as a system-level experience embedded across Samsung devices rather than confined to individual applications. The company says the move reflects changing user behaviour as artificial intelligence becomes more integrated into everyday routines.
Recent insights cited by Samsung show that nearly eight in 10 users now rely on more than two types of AI agents depending on the task at hand. In response, the company says it is evolving Galaxy AI to support a broader range of integrated agents, allowing users to choose experiences that best suit their needs and preferences.
Unlike standalone AI tools that operate within single apps, Galaxy AI has been built into the operating system framework. This enables it to interpret user context and reduce the need to switch between applications or repeat commands. According to Samsung, the system works in the background, coordinating tasks across services while maintaining a seamless Galaxy interface.
The expansion also includes deeper collaboration with external partners. Supporting services such as Perplexity will be integrated into the Galaxy environment, with Samsung curating the experience to ensure consistency across devices.
“We’ve been committed to building an open and inclusive integrated AI ecosystem that gives users more choice, flexibility and control to get complex tasks done quickly and easily,” said Won-Joon Choi, President, Chief Operating Officer and Head of the R&D Office, Mobile eXperience Business at Samsung Electronics. “Galaxy AI acts as an orchestrator, bringing together different forms of AI into a single, natural, cohesive experience.”
As part of the multi-agent rollout, Samsung will introduce Perplexity as an additional AI agent on upcoming flagship Galaxy devices. Users will be able to activate the service using the dedicated voice wake phrase “Hey Plex” or through quick access controls such as pressing and holding the side button.
Perplexity will be embedded across selected Samsung applications including Samsung Notes, Clock, Gallery, Reminder and Calendar, as well as certain third-party apps. The company says this integration will enable smoother multi-step workflows, allowing users to transition between tasks without manually managing separate applications.
Samsung says the broader strategy is to make AI interactions feel more intuitive and less fragmented. By positioning Galaxy AI as an orchestrator at the system level, the company aims to create what it describes as a richer and more flexible experience across devices.
Further details about supported devices and capabilities are expected to be unveiled during a livestream of Galaxy Unpacked scheduled for Wednesday, February 25 at 6pm.
