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.

1I had no idea there was a LS Research Assistant. Thanks for pointing that out. It's only taken me like 5 years to discover this very handy feature! Apr 27, 2017 at 22:58

There is a way to manually consult that database without send the request? For example through a website? Feb 23, 2018 at 22:44
As described in
/System/Library/PrivateFrameworks/CoreParsec.framework/Versions/Current/Resources/Info.plist
it is location-based suggestions for Siri.

1@SimonWoodside 's quote is from the "Privacy - Location Usage Description" in the Info.plist. Although it doesn't mention Siri in that description, siri does show up in the "Bundle identifier" entry in that file: "com.apple.siri.parsec.CoreParsec"– jk7May 12, 2018 at 21:09

2even though i have siri off, location services for siri off, and using nexdns.io (which blocks api.smoot.apple.com)
parsecd
is still not giving up and going crazy eating the cpu. 18k requests were already blocked. excellent job apple.– minusfApr 20, 2020 at 10:02
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.

doesn't have an entry
