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.
