01Adoption beats features

The best platform is the one people already open every morning. An agent in a tool nobody uses will not be used either.

02Integration and governance

Slack has a broad app ecosystem and flexible bots. Teams integrates tightly with Microsoft identity, SharePoint and compliance features. Both support threads, mentions and interactive approval messages.

03Mixed environments

Groups with subsidiaries on different tools benefit from agents that run in both. Switch agents run in Teams and Slack, so the workflow stays the same regardless of chat platform.

Frequently asked questions

Which is more secure?

Both offer enterprise-grade security; the bigger factor is how agent permissions are configured.

Should we switch chat tools for AI?

Rarely. Bring the agent to the tool instead.
