Some of the best answers in your organisation are not in any knowledge base. They are in Slack threads. The engineer who explained that bug fix in #engineering. The CS lead who wrote out the correct refund process in #support. The onboarding doc someone shared in #general six months ago.
Connecting Slack as a source lets your agent learn from those conversations. The institutional knowledge that usually lives and dies in a chat thread becomes something your agent can use to answer questions - and your team stops having to re-explain the same things every time someone new asks.
In this article, you'll learn:
- What gets synced when you connect Slack as a source
- How to connect your Slack account
- How to manage the connection
What Gets Connected
When you connect Slack as a knowledge source, Outlearn syncs messages and conversations from the channels or threads you authorize. Your data stays in Slack - Outlearn reads it, it never modifies or moves it.
Note: Connecting Slack as a knowledge source is different from deploying your agent inside Slack. This article covers using Slack as a source only. To deploy your agent to Slack, see Deploying to Slack.
How to Connect Slack
- Go to the Sources tab.
- Click + Add Knowledge.
- In the Add Knowledge Sources modal, click Team Chats in the left panel.
- Select Slack.
- Log in to your Slack account when prompted and authorize Outlearn to access your messages.
- Follow the on-screen steps to select which channels or conversations to sync and set accessibility.
After Connecting
Once connected, Slack will appear in your Sources list and Outlearn will keep it in sync automatically.
From the Sources list you can:
- Change accessibility using the dropdown next to the source.
- Toggle it on or off using the In Use toggle.
- Resync manually using the three-dot menu.
- Delete the connection using the three-dot menu.
Best Practices
- Be selective about which channels you connect - not every conversation is useful as a knowledge source. Focus on channels where team members share answers, guides, or resolved issues.
- Set accessibility to Internal - team chat content is almost always internal knowledge not suited for public-facing agents.
- Avoid connecting channels with high noise-to-signal ratios (e.g., general chat, off-topic channels) as this can dilute answer quality.
