Connect the Contrast Slack app, choose where Contrast answers, and understand whose access it uses.
Contrast answers data questions in Slack. Connect it during setup, then ask in a direct message, by mentioning @Contrast in a channel, or in a thread Contrast is already in. You can also ask on Home in Contrast. See Ask Contrast for how to ask good questions and correct answers.
A workspace owner or admin in Contrast selects Connect Slack in setup, or Connect Slack in the Set up your workspace checklist on Home, and approves the Contrast app in Slack. If your Slack workspace restricts app installs, a Slack admin may need to approve the request.
Then select Open Contrast in Slack on the last setup screen. This turns on answers. It appears once a source and Slack are both connected. Until Contrast is turned on, it replies that setup isn't finished.
You can also add Slack from Sources under Chat. That installs the app but does not turn on answers; finish from the Set up your workspace checklist.
| Where | How |
|---|---|
| Direct message | Every message to Contrast gets an answer. |
| Channels | Mention @Contrast. Add Contrast to the channel first, for example with /invite @Contrast. |
| Threads | Once Contrast replies in a thread, follow-ups meant for Contrast don't need another mention. Contrast skips replies that are clearly for someone else. |
Contrast doesn't answer in shared channels, including Slack Connect channels, or answer bots or people outside your Slack workspace. Contrast reads message text only; it doesn't open attached files, and it ignores edits to a message it has already seen.
If your Slack workspace is connected to more than one Contrast workspace, mention @Contrast switch workspace in a channel to choose which one that channel uses.
Contrast answers with the access of the owner or admin who connected Slack. Anyone in your Slack workspace who can message Contrast can get answers drawn from every source that person can see, whether or not they have a Contrast account.
Before you connect, check that the sources in your workspace are ones everyone in your Slack workspace may see. Keep sensitive data in a separate Contrast workspace that isn't connected to Slack.
If the connecting admin leaves the workspace or loses the admin role, Contrast stops answering and replies that its workspace access needs attention. Contact support@embrasure.ai to move Contrast to another owner or admin.
Opening How Contrast answered requires a Contrast account linked to your Slack user, and access to the answer.
Contrast can also post insights it finds in your data on its own. In Settings → Alerts, choose whether insights go privately to the person who connected Slack, to a shared channel, or nowhere.
