Slack is where your team thinks out loud — decisions get made, context gets shared, and institutional knowledge flows freely through channel threads. When you connect Slack to Hyper, those conversations become part of your shared AI memory layer. Agents can search across all your channels using native Slack syntax, retrieve full thread context, and surface relevant discussion history exactly when you need it. Hyper supports multiple Slack workspaces, so teams working across organizations can connect everything in one place.

​
Connect Slack

1

Open Settings in the Hyper desktop app

Launch the Hyper desktop app and click Settings in the navigation, then select Connections.
2

Click Connect next to Slack

Find Slack in the list of available integrations and click Connect. If you want to add multiple workspaces, you’ll repeat this step for each one.
3

Authorize with Slack OAuth 2.0

A Slack authorization window opens. Sign in to the workspace you want to connect and approve the requested permissions. Hyper uses a user token (not a bot token), which enables the search:read scope required for full message search. Your Slack password is never stored by Hyper.
4

Wait for the initial sync to complete

Hyper fetches recent threads from your channels and begins indexing them. Progress is visible in Settings → Connections.
5

Add more workspaces (optional)

To connect additional Slack workspaces, return to Settings → Connections and click Connect next to Slack again. Each workspace appears as a separate connection entry.
Hyper uses a Slack user token, not a bot token. This means it searches as you and can only access channels your account can already see — no elevated permissions are granted.

What Hyper Syncs

Channel threadsRecent threads from channels your account has access to
Multiple workspacesEach connected workspace is synced independently
DeduplicationContent-hash dedup prevents duplicate threads from appearing in search results
Source linksEach message links back to its Slack permalink
Hyper reads Slack message content only — it never posts, reacts, edits, or deletes any messages on your behalf.

​
Search Slack with AI Agents

Once connected, your AI agents can query Slack using native Slack search syntax or natural language. Hyper translates your intent into the right search query and returns relevant threads. Supported search operators:
OperatorExampleWhat it does
from:from:@aliceMessages from a specific user
in:in:#engineeringMessages in a specific channel
before:before:2024-06-01Messages sent before a date
after:after:2024-01-01Messages sent after a date
has:linkhas:linkMessages containing a URL
is:threadis:threadThreaded replies only
Example agent queries: 
Find the Slack discussion about the API migration in #engineering
Search Slack: from:@bob in:#product has:link
Show me threads about the new design system from last month
Read the full thread about the incident on March 5th
Find conversations mentioning "deployment freeze" in #devops
Agents can also read the complete content of a specific thread by providing its channel_id:message_ts identifier, giving full context for long discussions. What agents can do:
ActionDescription
SearchQuery across all indexed threads with Slack operators
Read threadRetrieve all replies in a specific thread by channel_id:message_ts
Multi-workspace searchSearch across all connected workspaces simultaneously

​
Reconnect Slack

If your Slack OAuth token expires or is revoked, Hyper will display a Reconnect prompt in Settings → Connections.
1

Go to Settings → Connections

Open the Hyper desktop app and navigate to Settings → Connections.
2

Click Reconnect next to the affected workspace

Each workspace has its own connection entry. Click Reconnect next to the workspace that needs re-authorization.
3

Complete the Slack OAuth flow

Authorize Hyper in the Slack window that opens. Your previously indexed messages are preserved — sync resumes from where it left off.

​
Disconnect Slack

To remove a Slack workspace from Hyper, go to Settings → Connections, find the workspace entry, and click Disconnect. This revokes Hyper’s token for that workspace and stops future syncing.
Disconnecting a Slack workspace removes all indexed message data for that workspace from Hyper’s memory layer. Other connected workspaces are unaffected.
