• Samsung hints that the feature could expand to additional Galaxy devices.

Announcement

Samsung announced that it is doubling down on agentic AI for the upcoming Galaxy S26 series by adding Perplexity as an additional AI agent alongside the revamped Bixby. The move signals a shift from a single‑assistant model to a multi‑agent ecosystem that can coordinate different AI services based on the task at hand. Samsung cites internal data showing that nearly eight in ten users rely on more than two AI agents, switching tools depending on the job.

How will Perplexity work on the Galaxy S26 series?

We first reported on the “Hey Plex” hotword in January, uncovering code that supports Samsung‑specific voice activation. With the official rollout, the details are clear:

• Activation – Users can launch Perplexity by saying “Hey, Plex” or by pressing and holding the side button.
• Integration – The agent is available inside core Samsung apps (Notes, Calendar, Gallery, Clock, Reminders) and select third‑party apps, allowing seamless continuation of workflows without juggling multiple apps.
• System‑level agent – Perplexity is not just another chatbot; Samsung positions it as a system‑level AI that understands context across the OS and can handle multi‑step tasks in the background.

In practice, a user could ask a question, retrieve relevant information, create notes or reminders, and schedule events—all with a single prompt, without hopping between separate applications.

Samsung has also launched a beta for the latest Bixby version, upgrading it to a conversational device agent. This reinforces the strategy of an open, multi‑agent ecosystem where different AI services coexist on the same device, operating at the framework and OS level rather than being confined to individual apps.

“Hey, Plex” availability

For now, the Perplexity integration is limited to the Galaxy S26 series. Samsung says more details about supported devices and experiences are forthcoming, suggesting that older flagships and other Galaxy devices may eventually receive the feature.
