How we compared them
All three apps answer questions and can help with everyday tasks, but they serve different purposes. Google Assistant focuses on voice commands and Google services; ChatGPT is a general-purpose conversational assistant; Perplexity is oriented toward answering questions with web research.
This comparison weighs their Google Play ratings, reach, pricing and declared features to help you decide which one fits your routine.
How we compared them
We compared the Google Play ratings and install counts, along with price, in-app purchases and ads. The figures were read on November 7, 2026, so they reflect the store information on that date rather than a hands-on performance test.
We also considered each app’s stated uses and the strengths and trade-offs described for it. Google Play data safety details are included only for ChatGPT: it declares sharing device or other IDs and collecting several categories of app, diagnostic and personal data, while also declaring encryption in transit and a way to request deletion.
