Slack is where the team actually talks: decisions, asks and updates in channels and threads, gone from view in a day. Google Drive holds the files: docs, sheets and folders named by whoever made them. Someone asks in a channel for "the latest version of the proposal"; four people reply with four links to Google Drive, two of them to old copies.
Liaison reads Slack and Google Drive together, knows which file each thread is about, and answers the question from the document itself: what it says, which version is current, who changed it last.
On Professional we connect your tools, bring your data in and set up the first rules with you. Anything that moves money waits for your yes.

It answers when asked and posts only the kinds of replies you approved once. Nothing else.
Everything you give it access to in Google Drive, in the formats it can open. It tells you when it could not read a file rather than guessing.
