AI Work Assistants & Office Copilots
Built-in AI for Slack that summarizes channels and threads, answers questions from your message history, and generates daily recaps.
Slack AI adds native AI features to the Slack messaging platform. It generates summaries of channels and threads so people can catch up without scrolling, produces recaps of recent activity, and answers natural language questions using the organization’s Slack message history as the source.
Because years of institutional knowledge often sit in Slack conversations, the search and Q&A features can surface decisions and context that are otherwise hard to find. Summaries include references back to the original messages so users can verify the source.
It is an assistant for communication rather than for documents or email, so it complements rather than replaces a suite copilot. Its usefulness tracks directly with how central Slack is to a company’s daily communication.
The concrete work teams hand to Slack AI.
Slack-centric organizations where significant knowledge and decision-making lives in channels and threads.
Teams that do not use Slack as their primary communication tool, or buyers wanting an assistant that works inside documents, spreadsheets, and email.
Available on Slack paid plans, which are billed per user; AI feature availability varies by plan tier.
