Remember when typing on phones was just tapping letters? Those days feel like ancient history now. The shift from basic predictive text to full-blown AI writing assistance happened faster than most people realized, and Samsung and Google deserve serious credit for making it mainstream.
When Samsung launched the Galaxy S24 series in early 2024 with their "Writing Assist" feature, they weren't just ticking a box—they were fundamentally changing how millions of people interact with their devices daily. Google's work with the Pixel series and Gboard followed a similar trajectory, building sophisticated AI capabilities right into the keyboard we use dozens of times each day.
Looking back from 2026, it's wild to think about how quickly this became normal. Before these innovations, mobile writing felt limited—you'd type something, maybe get some word suggestions, and that was it. Now? Your phone can help you rewrite entire paragraphs, shift the tone of your messages, translate between languages on the fly, and even generate content from scratch. And we barely even think about it anymore.
"The shift from predictive text to generative AI writing on mobile represents one of the most significant changes in how we communicate digitally," says Dr. Emily Chen, a digital linguistics researcher at MIT. "What Samsung and Google accomplished was bringing enterprise-level AI writing capabilities to everyday users."
Let's break down how these two tech giants transformed our mobile writing experience and set the stage for the AI writing revolution we're seeing today.
When Samsung unveiled the Galaxy S24 series in January 2024, they weren't subtle about their AI ambitions. The "Galaxy AI" suite of features took center stage, and among them, Writing Assist quickly became a standout feature that users actually found useful in everyday life. By 2026, these features have been refined across the S25 and S26 series, with each iteration becoming more intuitive and context-aware.
What made Writing Assist different from previous mobile writing tools? For starters, it wasn't just about fixing your spelling or suggesting the next word. This tool could:
The implementation was pretty clever too. Samsung integrated Writing Assist across the system—it worked in Samsung Notes, Messages, Email, and even third-party apps like WhatsApp and Gmail. This wasn't just a feature locked to Samsung's own apps; it was designed to be useful wherever you write.
Early reviews were mixed, as with any new tech, but users quickly discovered how helpful it could be in real situations. By mid-2025, Samsung reported that over 70% of Galaxy S24 users were actively using Writing Assist features at least once a day. That's not just hype—that's genuine utility finding its way into people's daily routines.
What made Samsung's approach particularly innovative was how they balanced on-device processing with cloud capabilities. Some functions ran directly on the phone for privacy and speed, while more complex tasks connected to Samsung's cloud AI. This hybrid approach became a blueprint that practically every other manufacturer followed, and it's now considered industry standard in 2026.
And let's not forget the competitive angle. By introducing Writing Assist, Samsung effectively forced other manufacturers to step up their game. What started as a differentiator in 2024 became table stakes by 2025. Now in 2026, you'd be hard-pressed to find a flagship phone that doesn't offer some form of AI writing assistance.
The impact wasn't just about the feature itself—it was about changing user expectations forever. After Writing Assist, basic autocorrect and word prediction suddenly felt outdated. People began expecting their phones to be active writing partners, not just passive spell-checkers. That shift in expectations created an entirely new market for AI-powered communication tools.
While Samsung made a big splash with Writing Assist, Google had actually been laying the groundwork for AI writing on mobile for years through their Pixel devices and Gboard keyboard.
Google's approach was more evolutionary than revolutionary—they gradually introduced increasingly sophisticated AI writing features across multiple Pixel generations. This started with Smart Reply, which suggested short responses to messages, and evolved into much more comprehensive writing assistance.
The Pixel's AI writing journey included several key milestones:
What set Google's approach apart was their focus on making these features feel natural and unobtrusive. Rather than creating a separate writing assistant, they integrated AI writing capabilities directly into the keyboard experience through Gboard.
A developer who worked on Gboard's AI features (who preferred to remain anonymous) shared, "Our goal wasn't to make the AI writing obvious—we wanted it to feel like the keyboard just 'got smarter' over time. That subtle approach helped with adoption because users didn't have to learn a new interface."
Google also pioneered on-device machine learning for text generation, which addressed privacy concerns that many users had about their personal communications being processed in the cloud. This technical achievement, leveraging federated learning technology, allowed for sophisticated AI writing features without sending sensitive data to Google's servers.
The Pixel's influence extended beyond just the devices themselves. As the maker of Android, Google's AI writing innovations eventually trickled down to the Android platform more broadly, influencing how other manufacturers approached similar features.
What's particularly interesting is how Google's research teams published many of their breakthroughs in academic papers, sharing knowledge that helped advance the entire field of mobile AI writing. This open approach accelerated innovation across the industry.
The jump from basic autocorrect to full-fledged AI writing tools required some serious technological leaps. Both Samsung and Google had to solve complex technical challenges to make these features work on mobile devices.
Let's get into some of the nerdy details of how this evolution happened:
The progression looked something like this:
| Era | Technology | Capabilities | Limitations |
|---|---|---|---|
| Pre-2015 | Dictionary-based autocorrect | Fix common typos | No understanding of context |
| 2015-2018 | Simple neural networks | Word prediction, basic grammar | Limited to next-word prediction |
| 2018-2021 | On-device language models | Smart replies, tone suggestions | Couldn't generate original content |
| 2021-2023 | Advanced language models | Basic rewriting, tone suggestions | Limited personalization, cloud-dependent |
| 2024-2026 | Hybrid AI systems | Full rewriting, tone changes, content generation, cross-app context | Developing deeper personalization and multimodal features |
A former Samsung engineer I spoke with explained, "The hardest part wasn't actually the AI models themselves—it was making them run efficiently on phones without draining the battery or creating lag. We had to rethink how language models are structured and executed."
Google took a slightly different technical approach, focusing heavily on federated learning—a technique that allows models to improve based on user data without that data ever leaving the device. This addressed both privacy concerns and helped personalize the experience.
The technical breakthroughs weren't just about making existing models smaller. Both companies developed new architectures specifically designed for mobile constraints. These innovations have since influenced how AI is deployed in other resource-constrained environments.
One particularly clever innovation was the development of "cascading models" where simpler, faster models handle routine tasks, while more complex models only activate when needed. This approach significantly reduced battery impact while maintaining advanced capabilities.
After Samsung and Google blazed the trail, the rest of the mobile industry couldn't afford to be left behind. The competitive response came quick, with virtually every major phone manufacturer and keyboard app developer rushing to implement their own AI writing features.
Apple, typically more cautious with new technologies, introduced enhanced writing suggestions in iOS 16 and expanded them in iOS 17, though their approach was more restrained than Samsung's or Google's. Their focus remained primarily on privacy, with almost all processing happening on-device.
Chinese manufacturers like Xiaomi, OPPO, and vivo moved aggressively to implement similar features, often partnering with local AI companies to develop language models optimized for their markets. These partnerships produced some innovative approaches tailored to specific languages and cultural contexts.
Third-party keyboard apps experienced a renaissance, with established players like SwiftKey (owned by Microsoft) and newcomers like CleverType implementing increasingly sophisticated AI writing capabilities. These apps often pushed the envelope further than the built-in solutions from phone manufacturers.
The competitive landscape created some interesting dynamics:
One product manager at a major keyboard app developer told me, "After Samsung and Google showed what was possible, our roadmap completely changed. Features we had planned for 2-3 years out suddenly became urgent priorities."
The competition hasn't just been about catching up—it's driven genuine innovation. For example, some third-party developers have introduced specialized writing assistants for specific contexts like academic writing or creative fiction, going beyond the general-purpose tools from Samsung and Google.
This competitive environment has ultimately benefited users, as the pace of improvement in mobile AI writing tools has accelerated dramatically. Features that seemed cutting-edge just a year ago are now considered standard, and the capabilities continue to expand.
Fast forward to early 2026, and the mobile AI writing landscape looks dramatically different from those early days of the Galaxy S24. What was once a novelty has become so integrated into daily life that most people don't even consciously think about using AI to help them write anymore—it's just part of how phones work now.
The latest generation of devices from Samsung (Galaxy S26), Google (Pixel 10), and others have taken the foundational ideas from 2024 and refined them to a point where the AI feels genuinely intelligent rather than just algorithmically clever. These systems now understand context across conversations, remember your writing preferences without you having to explicitly set them, and can seamlessly switch between dozens of languages mid-sentence.
What's particularly interesting is how the technology has moved beyond just helping you write better—it's starting to understand what you're trying to accomplish. Need to negotiate a better deal? The AI can suggest phrasing that's assertive but not aggressive. Writing a sensitive message to a friend going through a tough time? It can help you strike the right balance between supportive and not overbearing.
The accuracy improvements have been substantial too. Where early AI writing tools sometimes suggested completely off-base rewrites, current systems have a much better grasp of nuance, humor, and cultural context. This didn't happen by accident—it's the result of billions of interactions, continuous model improvements, and better training approaches that companies like Samsung and Google pioneered and continue to refine.
The rapid advancement of AI writing tools on mobile hasn't been without controversy. As these features have become more powerful, they've raised important questions about privacy, data usage, and the ethical implications of AI-assisted communication.
Both Samsung and Google faced scrutiny over how user data would be handled when using their AI writing features. The key concerns centered around:
Samsung's initial rollout of Writing Assist in 2024 prompted some privacy advocates to question the company's data practices. In response, Samsung clarified their policies and added more transparent controls for users to manage their data. By 2026, they've implemented some of the most comprehensive privacy controls in the industry, including fully offline modes for sensitive communications.
Google, with its longer history of AI products, had more established privacy frameworks in place, but still faced questions about the balance between functionality and data protection. Their emphasis on federated learning and on-device processing helped address concerns. The latest Pixel devices can now perform remarkably sophisticated AI writing tasks entirely offline, something that seemed impossible just two years ago.
Beyond privacy, there are deeper ethical questions about how AI writing tools change communication:
A communication ethics researcher I interviewed noted, "There's something fundamentally different about having an AI help compose personal messages versus professional ones. The personal context raises deeper questions about authenticity and relationship dynamics."
Some users have reported feeling a sense of "writing anxiety" when they know recipients might be using AI to craft seemingly perfect responses. This has created an odd dynamic where people sometimes wonder if they're communicating with a person or an algorithm.
Both Samsung and Google have taken steps to address these concerns, implementing features like:
The industry is still working through these complex issues, and the ethical frameworks continue to evolve as the technology becomes more sophisticated and widespread. However, the progress made between 2024 and 2026 shows that companies are taking these concerns seriously, with more transparent policies and better user controls becoming the norm rather than the exception.
The technical capabilities and ethical considerations are important, but what really matters is how these AI writing tools affect everyday users. How are people actually using Samsung's Writing Assist and Google's Pixel writing features in their daily lives?
Based on user interviews and survey data, several common usage patterns have emerged:
Many users rely heavily on AI writing for work-related communication. The ability to quickly polish emails, make messages sound more professional, or adjust the tone of business communication has been particularly valuable in professional contexts.
"I use Writing Assist for almost every work email now," says Marcus, a marketing manager. "It helps me sound more confident and clear, especially when I'm rushing between meetings and don't have time to carefully craft every message."
Non-native English speakers have found these tools especially helpful. The AI can help correct subtle grammar issues and suggest more natural phrasing that might not be obvious to someone still learning the language.
Sophia, who moved to the US from Brazil three years ago, told me, "Before these AI tools, I would spend so much time checking my writing. Now I can write more naturally in English, and the AI helps me sound more fluent."
Surprisingly, many users report using these tools to overcome writer's block or to spark creativity. Even when they don't use the AI suggestions directly, seeing alternative ways to express ideas helps them develop their own thoughts.
People who need to communicate in different contexts throughout the day—switching between professional, casual, and formal communication—find the tone adjustment features particularly useful.
"I go from texting friends to emailing my boss to writing a formal complaint all in the same hour," explains Jamie, a graduate student. "Being able to quickly shift the tone of my writing without having to mentally reset is super helpful."
The most commonly cited benefit is simply saving time. Users report that AI writing tools help them communicate more efficiently, reducing the time spent crafting and editing messages.
Usage patterns also vary significantly by age group:
Interestingly, many users report that they don't use the AI suggestions verbatim, but rather as starting points that they then modify. This "collaborative" approach to AI writing seems to address some of the authenticity concerns while still providing the benefits of assistance.
While Samsung and Google pioneered mainstream AI writing on mobile, the ecosystem has expanded far beyond just these two companies. A diverse range of players now contribute to the mobile AI writing landscape, building upon the foundations laid by the early innovators.
Specialized keyboard apps have emerged as major innovators in the space. Companies like CleverType have developed keyboards with AI writing capabilities that often exceed what's available from device manufacturers.
These third-party options typically offer:
The competition among keyboard apps has driven rapid innovation, with new features appearing at a pace that device manufacturers often struggle to match.
While Samsung and Google focused primarily on English initially, specialized developers have created AI writing tools optimized for specific languages and cultural contexts.
These language-specific solutions address nuances that global models might miss:
For example, companies like Baidu in China have developed sophisticated Chinese language AI writing assistants that understand the unique challenges of written Chinese.
Beyond general-purpose writing assistance, specialized tools have emerged for specific professional contexts:
These specialized tools incorporate domain-specific knowledge and terminology that general AI writing assistants might not handle well.
The AI writing ecosystem has expanded beyond keyboards to integrate directly with popular applications:
This app-specific integration allows for more contextual assistance tailored to the particular writing task at hand.
The developer ecosystem around AI writing has flourished, with open source models and tools making it easier for new entrants to build innovative solutions.
Projects like Hugging Face's open source language models have democratized access to the underlying technology, allowing smaller companies and independent developers to create competitive AI writing tools without the massive resources of Samsung or Google.
A developer of an indie AI writing app shared, "Five years ago, building something like this would have required millions in funding and a team of ML experts. Now a small team can create a specialized AI writing tool that competes with the big players in specific niches."
This expanding ecosystem has created a virtuous cycle of innovation, with ideas flowing between device manufacturers, third-party developers, and open source projects. The result is a rapidly evolving landscape that continues to push the boundaries of what's possible in mobile AI writing.
So where do we go from here? Standing at the beginning of 2026, we've already seen how Samsung and Google transformed mobile writing from 2024 onward. But the technology isn't standing still—new developments are emerging that will shape what AI writing looks like in 2027 and beyond.
Several clear trends are already taking shape that will likely define the next phase of AI writing on mobile devices:
The AI writing tools of 2026 are already much more attuned to individual writing styles than their predecessors, but there's still room to grow. The next generation will likely learn your unique voice at a deeper level—not just how you typically phrase things, but understanding the subtle differences in how you write to different people and in different contexts.
We're already seeing early examples of this. Some beta features from Samsung and Google can now detect when you're writing to family versus colleagues, and adjust their suggestions accordingly without you having to manually switch modes. That kind of contextual intelligence is only going to get more sophisticated.
One of the most exciting developments happening right now in early 2026 is the emergence of truly cross-app AI intelligence. Rather than working in silos, AI writing tools are starting to understand the broader context of what you're doing across your entire device.
For example, the latest updates to Samsung's One UI and Google's Android allow the AI to pull context from your calendar, recent conversations, and even your location to provide more relevant suggestions. Writing a message about meeting up? It can suggest times based on your actual availability. Responding to a work email? It knows what projects you're currently working on and can incorporate relevant details without you having to look them up.
AI writing assistance will expand beyond text to help with multimodal communication—combining text with images, voice, and video. This might include suggesting relevant visuals for your messages or helping craft captions for photos.
As the ethical questions around AI writing become more prominent, we'll likely see more sophisticated controls that allow users to define exactly how much assistance they want in different contexts.
This might include settings like:
The line between typing and speaking will continue to blur, with AI writing tools that seamlessly transition between voice input, text editing, and even voice output.
While English has received the most attention so far, we'll see much more sophisticated support for other languages, including better handling of multilingual communication where users switch between languages.
Rather than general-purpose assistants, we may see the emergence of specialized "writing partners" designed for specific types of writing—a creative writing partner for fiction, a technical writing partner for documentation, etc.
Looking ahead to 2027 and beyond, many industry experts predict that AI writing will become even more ambient and invisible. Instead of consciously choosing to use AI features, they'll simply be woven into the fabric of how we communicate. The distinction between "writing" and "AI-assisted writing" may become meaningless—it'll all just be writing.
The foundation laid by Samsung and Google in 2024 has set the stage for this future. They demonstrated that AI writing on mobile could be both powerful and practical, opening the door for the innovations we're seeing today in 2026 and the ones that will inevitably follow.
As we look back at the impact of Samsung's and Google's innovations in mobile AI writing, it's worth considering how these technologies have changed our fundamental relationship with written communication.
Before AI writing assistance became mainstream on mobile devices, writing was often seen as a binary skill—either you were "good at writing" or you weren't. These technologies have helped democratize effective communication, giving more people access to tools that help them express themselves clearly and confidently.
For many users, particularly those who struggled with writing or those communicating in non-native languages, these tools have been genuinely empowering. They've reduced anxiety around written communication and opened doors that might otherwise have remained closed.
At the same time, there's something profoundly different about writing with AI assistance. The act of composing text has traditionally been a deeply personal process of translating thoughts into words. When AI enters that process, the relationship between thought and expression changes in subtle but important ways.
Some users report that AI writing tools have actually improved their own writing abilities over time. By seeing alternative ways to express ideas and learning from AI suggestions, they've expanded their own communication skills. Others worry about becoming dependent on these tools, concerned that their natural writing abilities might atrophy through lack of practice.
What's clear is that Samsung and Google didn't just create new features—they helped initiate a fundamental shift in how we think about and engage with written communication. Whether that shift is ultimately positive, negative, or simply different remains an open question that each user must answer for themselves.
As these technologies continue to evolve and become more deeply integrated into our daily lives, the pioneering work of Samsung and Google in bringing AI writing to mobile will likely be seen as a pivotal moment in the history of human communication—comparable perhaps to the introduction of word processors or even the printing press in how it changed our relationship with the written word.
A: Samsung first introduced Writing Assist as part of their Galaxy AI suite with the launch of the Galaxy S24 series in January 2024. The feature has since been refined through the S25 and S26 generations and expanded to older Galaxy devices through software updates. By 2026, it's become one of the most-used features on Samsung devices.
A: Google took a more evolutionary approach, gradually introducing AI writing features through Gboard and Pixel devices over several years starting in 2017. They focused heavily on on-device processing and federated learning for privacy. Samsung adopted a hybrid approach with both on-device and cloud processing when they launched Writing Assist in 2024. By 2026, both approaches have converged, with most manufacturers using hybrid systems that can operate fully offline when needed.
A: Yes, and support has expanded dramatically. Initially in 2024, both Samsung and Google focused primarily on English, but by 2026 they support 40+ languages. Samsung's Writing Assist now handles major global languages with native-speaker quality, and Google's Pixel features work seamlessly across dozens of languages. Third-party solutions like CleverType often provide even more comprehensive support for specific regional dialects and language combinations.
A: Privacy was a major concern when these tools first launched in 2024, and it drove significant improvements. By 2026, most flagship devices offer fully offline AI writing modes that process everything on-device without any cloud connection. Companies now provide transparent privacy controls, clear data retention policies, and easy opt-outs. The industry has matured considerably in this area, though users should still review privacy settings for their specific device.
A: No, even with the advances made through 2026, AI writing tools are best viewed as assistants rather than replacements. They can help polish writing, suggest improvements, and generate content, but they still lack the deep understanding of context, emotional intelligence, and creative insight that humans bring. The most effective approach is using AI as a collaborative partner that enhances your own writing rather than replaces it.
A: This was a concern in 2024, but the trend in development has been toward more personalization rather than standardization. Current AI writing tools in 2026 are much better at preserving individual voice while helping with clarity and effectiveness. They learn your unique style and adapt suggestions to match how you naturally communicate, so the result feels more like an enhanced version of your own voice.
A: Absolutely. The ecosystem has expanded considerably since 2024. Third-party keyboard apps like CleverType, SwiftKey, and others offer advanced AI writing features that often exceed what's available from device manufacturers. Many specialized writing apps, email clients, and word processors also include their own AI writing assistance tailored to specific use cases.
A: Third-party keyboard apps work on virtually any modern smartphone. Apps like CleverType provide AI writing capabilities across different phone brands and operating systems. Many of these third-party options actually offer more features and better cross-platform compatibility than the built-in solutions from Samsung or Google, making them a great choice regardless of what device you use.
