Google is going all-in on Gemini – its next-gen AI assistant – as the connective tissue binding together the entire Android ecosystem. At Google I/O 2025, the company announced an ambitious plan to make Gemini the default assistant across phones, TVs, cars, smartwatches, and even upcoming AR/VR headsets.
In short, Google wants Gemini to be everywhere Android is.
This aggressive expansion marks a reimagining of Android with AI at the core, aiming to solve a long-standing problem: our devices have been smart in isolation, but rarely smart together.
Google’s bet is that a ubiquitous, context-aware assistant can seamlessly unify the user experience across all your screens and gadgets – if users embrace it.
Key Takeaways
- Google is replacing Assistant with Gemini across Android phones, watches, TVs, cars, and future XR devices.
- Gemini offers cross-device memory, letting it retain context between your phone, watch, and other gadgets.
- It integrates deeply with Google and third-party apps, making it more proactive and useful than previous assistants.
- Gemini uses your personal data (with permissions) for personalized help, but privacy trade-offs are a concern.
- Users can manage or opt out of Gemini’s data collection, but some features may be limited as a result.
- Google’s goal is to create a seamless, AI-powered ecosystem that rivals Apple and OpenAI’s offerings.
Gemini as the Connective Layer Across Android Devices
Google has completely reimagined Android with Gemini at the center, starting with phones and expanding across the entire device ecosystem. Gemini now ships by default on new Android phones, and existing devices will soon auto-upgrade, replacing Google Assistant entirely – a clear sign of Google’s confidence in this AI transition.
At I/O 2025, Google detailed Gemini’s rapid rollout: it’s coming to Wear OS watches, Android Auto, Google TV, and even Android XR headsets.
- On watches, it offers a voice concierge
- In cars, it understands natural speech for smarter navigation
- On TVs, it helps surface kid-friendly content or educational videos.
- And in XR, Gemini will act as a contextual guide – say, planning a trip while immersing you in maps, videos, and tips in AR.
Gemini is also headed to tablets, Nest speakers, smart displays, and earbuds.
As Google put it, nearly every Android-powered device is being upgraded to tap into the same AI system. The goal: one assistant that moves with you, from workouts to commutes to your couch.
Why the full-court press?
It’s a play to set Android apart with AI continuity across screens – something Apple and OpenAI can’t match yet.
Gemini’s ubiquity boosts convenience and loyalty. Once it’s everywhere, leaving the ecosystem could feel like abandoning your digital sidekick.
Smarter, Contextual & Cross-Device – Gemini’s New Capabilities
Gemini isn’t just showing up on more devices – it’s a smarter, more capable assistant.
Cross-Device Memory
A standout feature is its cross-device memory. Unlike the old Google Assistant, Gemini can hold context across conversations and screens. Ask something on your phone, follow up later on your watch, and it remembers. You can even review past chats, delete them, or turn history off entirely. It’s designed to be a continuity layer, stitching together your digital life seamlessly.
App Integration & Proactive Assistance
It’s also far more proactive and app-integrated. Gemini can act in Google apps like Gmail and Docs, but now also in third-party apps like WhatsApp and Spotify.
On Pixel Watch, it can fetch info from your phone’s Gmail and show it on your wrist. Instead of being a separate tool, Gemini becomes a natural extension of the apps you already use.
Advanced AI & Multimodal Capabilities
Under the hood, Gemini runs on Google’s latest large language model, enabling stronger reasoning, multimodal input, and real-time visual help.
With Gemini Live, it can “see” through your camera or screen, guiding you through issues or offering visual search.
In the car, it handles freeform voice commands, can summarize long texts, and even translate replies on the fly. It’s smart enough to give a spoken overview of your day or narrate a quick summary of an audiobook while you drive.
Personalization Through Context Awareness
It’s also getting more personalized. Gemini taps into your calendar, email, routines, and more (with permissions) to offer help before you ask. It might reschedule a meeting conflict or suggest a playlist when you start running.
Over time, this could become a true context-aware assistant, proactively managing parts of your life based on patterns and data signals.
Most importantly, Gemini keeps the experience consistent. Whether you’re talking to your watch, phone, or TV, it’s the same assistant – same brain, same memory, tied to your Google account.
That coherence builds trust and makes it feel like one unified AI, not a different bot on every screen.
What Data Does Gemini Collect, and Can You Opt Out?
An AI that’s everywhere naturally raises privacy questions. To function as the connective tissue across your devices, Gemini needs to gather quite a bit of contextual data.
Google’s documentation reveals that the assistant collects your conversations and related info (like device type, language, and general location) and retains them for up to three years by default. These stored conversations may be reviewed (anonymously) by human annotators to help improve Gemini’s responses.
In plain terms: if you’re chatting with Gemini, assume that data is being saved on Google’s servers and could be looked at by Google staff or contractors.
Google even issues a blunt warning to users: “Please don’t enter confidential information in your conversations or any data you wouldn’t want a reviewer to see or Google to use to improve our products.” In other words, treat Gemini chats with the same caution you’d treat email – don’t spill secrets to it.
The good news is that Google offers some control over this data harvesting. In your Google My Activity settings, there’s a “Gemini Apps Activity” toggle that is enabled by default but can be turned off.
If you leave it on, all your interactions with Gemini are saved to your Google account (and potentially kept for that multi-year span). If you turn it off, Google says future chats won’t be retained for long-term analysis.
You can also manually delete specific questions or whole chat threads from your history at any time.
However – and this is a big however – even with history turned off, Google will still store your last 72 hours of Gemini conversations.
They claim this brief retention is necessary “to maintain the safety and security of Gemini and improve the apps.” Essentially, the system needs a short memory buffer to function (and to monitor for abuse or misuse), but it won’t remember anything beyond three days if you’ve opted out of history.
By contrast, if you leave history on, that memory stretches for years, enabling richer personalization (and more training data for Google).
Gemini also gathers behavioral and contextual data from your devices when it’s acting as the device assistant.
For example, it can access things like your precise location (if you grant permission), your calendar events, contacts, and even details like the names of your smart home devices or your Spotify playlists – all the little context crumbs that help it answer you more helpfully.
For users who are uneasy about all this, Google’s message is essentially: we give you controls, but the magic works best if you trust us with your data.
Disabling Gemini’s data collection or refusing key permissions might limit some of the most compelling features (like continuity across devices or ultra-personalized help). It’s the classic trade-off in modern AI assistants – privacy versus convenience. At least on paper, Google’s privacy stance with Gemini is roughly on par with other big AI providers.
Will Users Embrace Google’s AI Everywhere?
Google’s Gemini push is a massive opportunity. No other company is better positioned to deliver a true cross-device AI assistant. Apple’s “Apple Intelligence” is limited – privacy-focused, yes, but far less ambitious.
Apple is even expected to let iPhone users replace Siri with third-party assistants like Gemini to comply with EU requirements. All of these point to the fact that Apple’s AI lags behind Google and OpenAI.
For a lot of us power adopters of technology, if Apple can’t pull off some of these features Google is showing with Gemini, no amount of blue bubble lock-in will stop us from moving to Android—especially when those features come to smart glasses.

OpenAI’s ChatGPT is powerful and has a voice, but it’s stuck in a standalone app. It lacks native access to your calendar, contacts, or routines – things Gemini integrates by default.
If Google gets this right, Gemini could give Android a serious edge. Imagine an AI that drafts your email on your laptop, reminds you about it on your phone, reads it aloud in the car, and lets you reply from your watch.
That’s the fluid, cross-device experience AI has long promised. It would lock users into Android, yes, but also deliver real value. Google has a shot to set the standard for how AI assistants fit into daily life.
The Bottom Line
Still, the risks are real. AI fatigue is creeping in, and not every “AI” feature solves a meaningful problem. If Gemini feels like clutter, users may tune it out – or turn it off. Google will have to get the balance right: proactive, not pushy. And privacy will be a constant pressure point. Google promises transparency and offers data controls, but it’s asking for deep access across your digital life. A single misstep could sour trust.
Ultimately, it comes down to trust and execution. Gemini could feel like a loyal assistant – or an intrusive presence. Google wants it to be your personal AI, helping you navigate the day. But it’s also everywhere, watching. Some will embrace that. Others won’t.
Google’s bet is bold and well-timed. With Gemini, they’re aiming to do for AI what they did for search. If they can overcome privacy concerns, avoid AI fatigue, and actually make life easier, Gemini could be the connective tissue of the entire Android experience. Apple may have the polish. OpenAI may have various models. But Google has the platform – and it’s moving fast.
