Korso uses these companies to run the Service. This page names each one that can
receive personal information about you, what it does for Korso, what it receives and
where it processes it. It follows the categories in Section 4 of our
Privacy Policy, which says more about each one. We update this
page when we add, replace or remove a provider.

attached files, the conversation so far and the results of actions you
approve. For dictation, the transcript and the name and window title of the

answer.

Checks each action Korso is about to take, on your computer or in a connected

and the action it is about to take, with their inputs: the app and window
title, the name of the control on screen, and any text the action would
change. Not your screenshot or Korso's answers.
