Samsung is turning its Galaxy phones into something closer to an AI control center than a single-assistant smartphone – and Perplexity is the latest agent to move in.

In a new announcement ahead of its Galaxy S26 launch cycle, Samsung said it is opening up Galaxy AI to Perplexity as a fully integrated AI agent, not just another app icon you ignore on page three of the home screen. Instead of forcing you to live inside one assistant, Samsung is leaning into the reality that most people already hop between multiple AI tools every day. Its internal research suggests nearly 8 in 10 users now rely on more than two AI agents, depending on what they’re trying to do. Galaxy AI’s response is simple: if users are going multi‑agent anyway, bake that behavior into the OS and make it feel seamless.

At the center of this move is a phrase you’re probably going to hear a lot in Samsung marketing: “Hey Plex.” On upcoming flagship Galaxy devices – starting with the Galaxy S26 series – that’s the voice wake word that pulls up Perplexity as a system-level agent. You can also get to it by long‑pressing the side button, effectively giving Perplexity the same kind of privileged fast lane that Bixby and Gemini enjoy today. This isn’t just about web searches, either. Perplexity is being wired directly into core Samsung apps like Notes, Clock, Gallery, Reminder and Calendar, plus select third‑party apps, so it can quietly orchestrate multi‑step workflows in the background instead of forcing you to jump between apps and repeat yourself.

Samsung’s language around this shift is very deliberate: Galaxy AI is the “orchestrator,” and Perplexity is one of the instruments. The company has spent the last year pitching Galaxy AI as a layer that lives in the operating system itself, not a bolt‑on chatbot, and this announcement is basically the logical extension of that pitch. Because Galaxy AI sits at the framework level, it can see what you’re doing across apps, hold context, and then decide which agent is the best fit for the job – Samsung’s own capabilities, Google’s Gemini, where supported, and now Perplexity for research-heavy and information-dense tasks. The endgame is that, instead of you thinking “which AI should I open,” the phone quietly routes the request to whatever mix of agents makes most sense.

That’s a very different philosophy from Apple’s tightly controlled Siri world, where one assistant sits on top of everything, and even from Google’s increasingly Gemini‑centric view of Android. Samsung is essentially betting that the “AI phone” era won’t be won by a single, monolithic assistant but by devices that can juggle multiple specialist agents without making the user feel that complexity. Commentators are already framing this as Samsung throwing down a gauntlet: instead of trying to out‑Siri Siri or out‑Gemini Gemini, it’s positioning Galaxy as the hub where all of these agents can coexist.

The Perplexity deal also comes at a strategically important moment. Galaxy Unpacked 2026 is being hyped as a pivot point where Samsung pushes deeper into extended reality, wearables and a broader “AI-first” Galaxy ecosystem, with the S26 pitched as an “AI smartphone designed for agentic tasks.” In that context, Perplexity isn’t just a nice‑to‑have extra; it’s part of a roadmap where you offload more and more multi‑step chores – trip planning, content summaries, editing, scheduling – to a network of agents that span your phone, watch, maybe even XR glasses. Today it’s “Hey Plex” in Notes and Calendar; tomorrow it could be Perplexity helping coordinate a cross‑device workflow that starts on your phone, continues on a headset, and finishes on a laptop, all mediated by Galaxy AI in the background.

From a user’s point of view, the appeal is obvious. Imagine drafting a blog post in Samsung Notes, asking Perplexity to turn your rough outline into a structured draft, grabbing relevant images from Gallery, and slotting reminders and deadlines into Calendar – all without manually hopping between apps or copying text around. Or saying “Hey Plex, catch me up on everything I missed about Galaxy AI today,” and getting a contextual brief that you can pin into Reminder or share straight from your phone. This is the kind of multi‑step, context‑aware flow that pure app‑based assistants struggle with and that system‑level agents are designed to unlock.

Of course, there are open questions. Samsung is still vague on which exact devices beyond the S26 lineup will get Perplexity, hinting that additional details, regions and feature sets will roll out over time, likely tied to One UI updates. There’s also the usual fine print: you’ll need a Samsung account for certain AI features, availability will vary by market and carrier, and Samsung is very clear that it isn’t guaranteeing the accuracy or reliability of any AI output. And with more agents in the mix, issues like privacy, data sharing between services and who sees what context when you talk to “Hey Plex” versus Bixby or Gemini will become important questions for power users to interrogate.

Zoomed out, though, this Perplexity integration feels like one of those small announcements that ends up being a big line in the sand. Smartphones started as app platforms; then they became camera platforms; now they’re turning into AI platforms where the OS decides which model or agent to call for any given moment. Samsung opening Galaxy AI to Perplexity and framing it as the first step in a broader multi‑agent ecosystem is a clear signal of where it thinks the next phase of the phone wars will be fought – not on who has the loudest assistant voice, but on who can quietly orchestrate the smartest mix of them behind the scenes.
