AI Slack Apps

62 tools in the catalog have a Slack app; 35 of them have a free plan and 30 also offer an API. Below are the top 60, ranked by Effect score — how much each tool is used and rated, how widely it is listed elsewhere, and whether it is alive.

These tools work inside Slack as an app or a bot: summarizing long threads and channels, answering questions from a team's documents, taking meeting notes, or turning a message into a ticket. Installing one is a workspace decision as much as a personal one, because a Slack app can read the channels it is added to.

What to check in a Slack app

  • Check the permissions it requests at install — public channels, private channels, direct messages, files — and whether they match what it does.
  • Find out whether a workspace admin has to approve it; many workspaces only allow approved apps.
  • Ask where messages are processed and how long they are kept. Slack history often holds things that never belonged in a third-party model.
  • Check whether it is priced per seat or per workspace; some Slack apps bill for every member of the workspace.
