Slack trains AI features on user messages and files by default
Slack uses user messages, files, and data to train its machine learning features such as channel recommendations and emoji suggestions. Users are opted in by default and cannot individually opt out; only workspace administrators can request exclusion via email. A user publicly criticized the practice, and Slack acknowledged the policy but did not change it.
