Which Digital Personal Assistant Is the Smartest?

Which Digital Personal Assistant Is the Smartest?

Last updated May 1, 2018 — This page now contains the 2018 update to our Digital Personal Assistants accuracy study. In this new edition of the study, we tested 4,942 queries on five different devices:

1. Alexa
2. Cortana Invoke
3. Google Assistant on Google Home
4. Google Assistant on a Smartphone
5. Siri

In today’s study, I’ll compare the accuracy of each of these personal assistants in answering informational questions. In addition, I’ll show how these results have changed from last year’s edition of this study, which was published on April 27, 2017. You can see this version of the study here.

For those of you who want the TL;DR report, here it is:

1. Google Assistant still answers the most questions and has the highest percentage answered fully and correctly.
2. Cortana has the second highest percentage of questions answered fully and correctly.
3. Alexa has made the biggest year-over-year gains, answering 2.7 times more questions than in last year’s study.
4. Every competing personal assistant made significant progress in closing the gap with Google.
