Slack is where the team actually talks: decisions, asks and updates in channels and threads, gone from view in a day. Notion holds the docs and the databases teams build around them: roadmaps, wikis, trackers. The gap between them is every request that was made in a thread and never written down, and every item in Notion whose real status is three messages deep in Slack.
Liaison reads Slack and Notion together, the way the one person who tracks everything would, and tells you what was asked, what was promised, and which of the two systems is out of date.
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 can post, and it does so only for the kinds of messages you approved once, such as a weekly status in a channel you chose. It never creates Notion items without your confirmation on each.
No. It reads the channels you give it access to, in full, and works out which messages are asks. You can also ask it directly in Slack.
Only after a yes. It drafts the item or the status change and shows you the thread it came from; you confirm, it writes.
