What's the best ChatGPT app for team chat?
Last tested .
Slack, at 80/100. It is strongest at the thing chat is worst at — catching up. Summarizing channels after time off, finding a decision buried in a thread, and drafting replies in context. Microsoft Teams is the pick only if your workplace already runs on Microsoft 365.
Why this is the pick
Slack scores 80 against Teams' 73 and its catch-up workflows — channel summaries, thread archaeology, in-context replies — are the clearest payoff of putting team chat inside a conversation.
