Slack integration

Connect Slack to bring your channels and DMs into Ion's context.

What it does

The Slack integration lets Ion:

  • Read messages from channels you select (read-only — Ion never posts without an automation).
  • Post messages via automations.
  • Index threads for AI search.
  • React to mentions and DMs.

Connecting

  1. Go to Integrations → Slack → Connect.
  2. Authorize Ion in your Slack workspace.
  3. Select which channels Ion should index.

Permissions

Ion requests the minimum Slack scopes needed:

  • channels:read — list channels.
  • channels:history — read messages in selected channels.
  • chat:write — post messages (only via automations you configure).
  • commands — enable the /ion slash command.

The /ion slash command

Once connected, you can use /ion in any Slack channel:

/ion What's blocking the launch?

Ion responds in a thread with citations from your workspace.
