What is parsecd?

The internet is not very satisfactory when it comes to this question, I found one somewhat related question here where someone says allowing parsecd internet access via Little Snitch made their keyboard input smoother. But what the heck does parsecd actually do? I do see it pop up regularly via Little Snitch, and I would love to know what it does. Can anyone shed some light?

According to Little Snitch Research Assistent it is used for Suggestions in Spotlight, Messages, Lookup and Safari and usually connects to api.smoot.apple.com.

As described in

/System/Library/PrivateFrameworks/CoreParsec.framework/Versions/Current/Resources/Info.plist

it is location-based suggestions for Siri.

Okay, well I disabled that know-it-all Siri right after installing Sierra a week ago, and today is the first parsecd request I’ve seen.

Location services were disabled under under El Cap, but I now see a Siri entry that’s checked but greyed out. I suspected that was because she was disabled so I reenabled her. But her location service is still checked and grayed out - no way to disable it!

Guess I’ll just have to block connections with LS to silence the cunning little witch.
