I tried Gemini, Perplexity, and Copilot for a month on Android, and the verdict is in

We have been used to the ‘Hey Google’ experience on Android for years.

But over the last month, my home screen became a digital battlefield. I spent 30 days rotating between Gemini, Perplexity, and Microsoft Copilot as my primary mobile AI.

From the seamless deep-hooks of Gemini 3.1 to the clinical research precision of Perplexity and the Office 365 muscle of Copilot, I have pushed these apps through every real-world scenario.

And after four weeks of testing, only one of these assistants actually earned its spot on my Pixel home screen.

It became a crucial part of my Android workflow

Microsoft Copilot

Enterprise productivity powerhouse

Microsoft Copilot is a beast when it comes to raw utility, largely because it’s backed by class-leading OpenAI models. It feels like a creative agency living in my pocket.

I found myself leaning on it for everything from generating high-quality images to drafting quizzes and even spinning up podcasts based on my notes.

The cross-platform reach is its biggest selling point. I connected both my Microsoft and Google services, and allowed Copilot to reach out and pull files from my cloud storage regardless of which ecosystem they were in.

If you are already paying for a Microsoft 365 subscription, the value proposition here is insane. It’s clearly designed to be the ultimate companion for desktop users who spend their lives in Word, Excel, PowerPoint, and OneNote.

However, the overall experience isn’t without its frustrations. Despite its power, Copilot still struggles with the small stuff that makes a mobile assistant truly useful.

While it can find my files, I still can’t ask it to pull a specific piece of information from within a document yet.

As someone who lives in digital notebooks, the lack of direct integration with OneNote was a bummer, too.

Even the Copilot reminders don’t sync with Microsoft’s own To Do app.

Overall, it’s a solid, high effort from Microsoft, but I would like to see better integration of Office apps in the future.

Perplexity

Source-backed research genius

Perplexity is my favorite librarian on Android. If I’m deep-diving into a complex technical topic for a new article or researching the historical background of a landmark in Ninh Binh, Perplexity is unmatched.

Every claim is backed by a citation, which is vital for the kind of fact-heavy writing I do.

The standout feature for me this month has been Spaces. It’s basically a collaborative brain for specific projects.

Perplexity recently introduced its much-awaited Computer feature — an agentic mode that can actually navigate the web and use tools on your behalf.

While it sounds like the future, I quickly found that it’s a feature best enjoyed on the desktop only. On a mobile screen, it feels cramped and prone to errors.

Although Perplexity doesn’t have connectors with Google or Microsoft services, it comes with some surprising capabilities.

For instance, you can ask it to play the final song from Skyfall, set intelligent reminders like remind me to watch the next season of Virgin River, book an Uber ride, and more. However, these are still niche use cases for me.

Google Gemini

Native Android OS power

If there is one thing I realized after 30 days, it’s that Google Gemini has nailed the basics of what a mobile assistant should be.

Because it’s a first-party citizen on Android, the integration with the Google apps I use daily is nothing short of superior.

I can have a long brainstorming session and, with a single tap, save the best parts directly into Google Keep. I can even create Google Tasks via voice without breaking my stride. It even has deep hooks into YouTube Music to let me spin up custom playlists on the fly.

But the real wow moments for me happened with Google Photos and Docs.

For example, I ran a prompt asking it to ‘Find my best four pictures from Hanoi and give a caption for Instagram,’ and it went through my library to find the best shots and drafted the copy in no time.

The same magic applies to Gmail and Docs, where I can ask it to find a specific flight detail or a buried clause in a contract, and Gemini surfaces the info instantly.

There is a trade-off, though. Gemini works best with Google’s ecosystem only. If you use OneNote or Word, or another cloud service like Box, you will soon run into limitations.

Android assistant face-off

I have found that the ‘best’ AI depends entirely on whether you want a researcher, a creator, or a personal secretary.

Each of these three AIs brought something unique to my Android experience, but only one felt like it actually belonged here.

Perplexity remains the gold standard for pure research. Its ability to cite sources and provide a trail of information is unmatched.

Microsoft Copilot is a powerhouse for anyone living in the Microsoft 365 world. It can search, read, and analyze my files in OneDrive, glance over my Outlook inbox and calendar, and even works with Google’s services like Drive, Contacts, Calendar, and Gmail.

If you live and breathe in the Office apps, Copilot is an obvious choice. However, if you prefer Google’s productivity apps like Tasks, Keep, Docs, and more, no one can beat Gemini’s implementation.

I was also surprised to see a robust Google Photos integration with Gemini. As of now, I’m switching between Gemini and Copilot to get the job done.
