What is Galaxy AI and which Samsung phones support it?

With AI tools like ChatGPT growing in popularity, it was only a matter of time before tech giants would begin incorporating the tech into smartphones. Google kicked off the trend, but now virtually all modern smartphones boast built-in AI features. Samsung was among the first manufacturers to embrace AI features and it’s now the centerpiece of its flagship devices like the Galaxy S25 series. Dubbed Galaxy AI, the software package replicates some of the features we’ve seen on rival smartphones while also introducing a host of new and exciting ones.

So what does Galaxy AI bring to the table and which of these new features are trickling down to older Samsung smartphones? Let’s break it down.

What is Galaxy AI and how does it work?

Modern phone chips like the Snapdragon 8 Elite are now capable of running generative AI models completely on-device. Samsung has collaborated with a host of partners, including chip maker Qualcomm and Google, to bring those capabilities to its smartphones under the Galaxy AI umbrella.

Having said that, even the latest SoCs won’t be able to run cutting-edge large language models like the one powering ChatGPT. So for the best results, some of Galaxy AI’s best features will rely on Samsung’s servers in the cloud for processing.

We’ve seen Google employ a similar strategy with its Pixel 9 series, where many features like Magic Editor don’t work without an internet connection. Having said that, Galaxy AI will allow you to choose between cloud-based and on-device models. You’ll get lower-quality results from the latter, and some advanced features might not be available, but it’s a small win for the privacy-conscious among us.

Galaxy AI features: What’s new?

Samsung has crammed several features under the Galaxy AI umbrella, and learning how to use them is one of the best Galaxy S25 tips we can provide. In short, we’ve grouped these features into two distinct categories. We’ll start with photography, arguably the centerpiece of the S25 series and Galaxy AI’s raw potential.

Photography and video

From the outset, Samsung says it turned to AI to improve the image quality of the Galaxy S24 series’ cameras. Dubbed ProVisual Engine, the software suite incorporates AI during the capture process and also while editing shots after the fact.

Galaxy AI first stretched its legs with the S24 series, which produces better shots in low-light conditions. Digital zoom quality improved, too, allowing the S24 Ultra to get an additional boost from a new 50MP sensor with 5x optical zoom. According to Samsung, the phone only relies on hardware to deliver shots at 3x and 5x zoom. At 2x and 10x zoom, shots combine the phone’s optics with Galaxy AI-driven enhancements for “optical-equivalent image quality”.

Galaxy AI plays an equally prominent role after you’ve captured your shot. Like Google’s Magic Editor on the Pixel, activating Samsung’s AI editing tool via the button pictured below will let you erase and move objects within photos. This Generative Edit feature will seem familiar if you’ve ever used an AI image generator like Midjourney. It can also fill in or expand an image beyond its original size, a practice commonly referred to as “outpainting” in AI circles.

Finally, Instant Slow-mo will let you transform a video shot in standard mode into a slow-motion clip. The feature will use AI to generate additional frames as slow-mo typically requires you to shoot at 120, 240, 480, or even 960 fps. This technique of adding new frames is already known as motion interpolation and is commonly used in televisions to make motion look more fluid. The non-AI approach is known to exhibit visual artifacts, so Galaxy AI has some heavy lifting to do here.

Samsung says the Gallery app will automatically add a watermark to any images modified using Generative Edit. This will signal to others that an AI edit was performed on the image.

Language, voice, and more

Galaxy AI includes a range of language-based features that work across both written text and voice. Here’s a quick rundown:

• Live Translate: Samsung’s built-in Dialer app is now capable of translating phone calls in real-time. The feature uses AI to generate voice and text translations of live phone calls both ways. In fact, the person you’re calling doesn’t even need a Samsung phone for Live Translate to work. The fine print notes that you’ll need an internet connection to use this feature, but Samsung also said the feature uses on-device AI to keep conversations private. We’re not completely sure if it’s usable offline.
• Interpreter: Similar to the Interpreter mode on Google’s Pixel Fold, this feature can transcribe and translate conversations in a split-screen view. And since it relies on an offline language model, it doesn’t require a network connection.

• Chat Assist: The Samsung Keyboard app is getting a number of AI features, ranging from translation to changing the tone of your messages. The latter will rewrite or edit your messages to suit different conversations. You’ll be able to choose from options like professional, casual, polite, and witty. On the cover display of the Galaxy Z Flip series, you’ll also see AI-generated reply suggestions based on the chat’s context, likely using Google’s Gemini Nano language model.
• Summarization and Note Assist: Galaxy AI will offer an option to summarize documents and websites as well as notes in the Samsung Notes app. The latter is part of a broader AI feature called Note Assist that will also offer pre-made templates, auto-generated covers, and transcription of voice notes.

• Transcript Assist: Samsung’s Voice Recorder app will now use AI to generate transcriptions, summaries, and translations of files and phone calls up to three hours in length. It is pretty similar to the Pixel-exclusive Google Recorder app.
• Sketch to image: Ever wished you could turn your simple doodles into full-blown art? Galaxy AI can do that for you, thanks to a built-in AI image generator.

• Circle to Search: To activate the feature, press and hold the home button (or the navigation bar if you use gesture navigation) and circle or tap any part of your screen. It will then perform a search related to your highlighted content and surface relevant results. Even though Circle to Search launched alongside the Galaxy S24 family, Samsung collaborated with Google to make it possible. Consequently, you’ll find Circle to Search on many other Android devices.
• Android Auto: This feature allows your phone to summarize incoming messages and suggest relevant actions. For example, the AI can suggest replying to an incoming message with your estimated arrival time.

Which Samsung phones support Galaxy AI?

All Samsung phones and tablets released this year support Galaxy AI. The suite was first rolled out to 2023 Samsung flagship phones and tablets with the One UI 6.1 update. This included the Galaxy S23 series and the Tab S9 family as well as foldables like the Galaxy Z Flip 5 and Z Fold 5. If you own an older Samsung device, you may have to head into the Settings app and check for updates.

In an unexpected turn of events at the time, Samsung announced that it would also bring its AI features to the Galaxy S22 series and other 2022 flagships like the Z Flip 4 and Tab S8. The One UI 6.1 update, which started rolling out in May 2024, brought Galaxy AI to these older devices. Future updates like One UI 8 will continue to deliver new AI features to older devices.

It’s a positive sign that Samsung continues to bring its latest AI features to previous year’s flagships. We’ve seen Google do the opposite with the Pixel series, after all. It also bodes well for future releases as you can take solace in the fact that you’ll likely get some of next year’s features if you buy a flagship Galaxy today.

Is Galaxy AI free for Samsung phones and tablets?

Yes, you can use Galaxy AI for free as long as you own a Samsung device that supports it. Whether you buy the flagship Galaxy Z Fold 7 or the more affordable A-series, you don’t have to pay a monthly subscription for the AI software suite.

The company’s mobile chief has outright said that it doesn’t intend to charge for Galaxy AI. And even a potential paid subscription tier will only introduce new advanced features instead of locking currently free features behind a paywall. Still, the roadmap for Galaxy AI’s pricing remains undecided for now. Given that a number of AI features rely on cloud processing, it’s only a matter of time before Samsung needs a way to monetize it.
