Perhaps the most interesting feature exclusive to Google Pixel, at least officially, is Google Assistant. We have a review of Assistant's current functionality, but in a nutshell, it's essentially a conversation-based version of the former Google Now. XDA user brianelv has posted a short guide on enabling Assistant, and it should work on any Android 7.0 (or higher) device with the Google app 184.108.40.206 or newer.
If you have those prerequisites, the actual guide is fairly short. All you need to do is change your build.prop file, reboot, and clear Google app cache. Either root (to manually edit the build.prop) or a custom recovery (if you want to flash the zip) is required. In our own testing on a Nexus 6P, switching to the Google Now Launcher might be required to trigger the Assistant setup.
If you want to try this out for yourself, check out the guide on XDA Forums for the full instructions at the source link below.
