Perplexity APIs deliver powerful AI to the world’s largest Android device maker

Perplexity is now integrated into Samsung Galaxy S26 phones at a deep level, powering search and reasoning for both the Perplexity assistant and Samsung's Bixby. That makes Perplexity the AI behind two of the three assistants on the device. 

We worked with Samsung to build the integration at the system level, with a dedicated wake word, access to physical controls, and the ability to read from and write to native apps like Notes, Calendar, Gallery, Clock, and Reminders. In fact, Perplexity is the first non-Google company to have OS-level access in a Samsung phone. Samsung had previously reserved this level of access for first-party assistants. Perplexity was selected for this access based on our commitment to accurate AI and our strength of orchestration across search, reasoning, and device-level actions.

How it works

Galaxy S26 users can say "Hey Plex" to launch the Perplexity assistant. They can also press and hold the side button. Because the integration runs at the system level, Perplexity can read from and write to Samsung's core apps directly. Users can:

• Ask questions and get sourced answers without opening a browser

• Save information directly into Samsung Notes from a Perplexity response

• Set reminders and add calendar entries through a single conversation

• Search across topics while staying inside whichever Samsung app they started in

The Perplexity app comes preloaded on every S26 with no download or setup required.

Perplexity powers Bixby's real-time answers

Samsung's Bixby uses Perplexity's APIs on the backend for its search and reasoning capabilities. The APIs combine real-time web search with large language model reasoning, so Bixby can deliver grounded, up-to-date answers rather than relying on static training data alone.

Samsung will also be integrating Perplexity's APIs into the Samsung Browser, with agentic browser capabilities perfected in our AI-first browser, Comet, and Perplexity as an optional default search engine. 

An open multi-agent model

Samsung designed the S26 around a multi-agent approach. Their internal data shows that 8 in 10 users already rely on more than two AI agents daily, and Samsung is the first major device maker to match the operating system to that behavior.

Across Perplexity Enterprise customers in 2025, no single AI model captured more than 23% of queries by year's end. People switched between models depending on the task. Samsung is applying the same principle at the device level, letting Galaxy AI coordinate between them.

Unprecedented access

Samsung is expected to ship hundreds of millions of devices this year, with Perplexity powering the assistants, browser agents, and search. No other AI company has this level of access on the world's most popular Android devices. Perplexity’s mission is to power the world’s curiosity, and with Samsung and Perplexity, more curious people with smart questions have access to the world’s knowledge than ever before.
