Slack Setup
Use this guide if your team works in Slack. Clark can answer in direct messages, respond when mentioned in channels, keep channel context, process files, reply in threads, and provide slash commands for common workflows.
Add Clark To A Workspace
- Open your Clark dashboard or ask the workspace owner to install Clark.
- Choose Add to Slack.
- Approve the Slack permission screen.
- Open one Slack channel where your team works.
- Invite Clark to that channel.
- Send a test message:
@Clark hello, what can you help this channel with?
Start with one channel. Once the team understands how Clark behaves, add more channels.
Direct Messages
In a Slack DM, you do not need to mention Clark. Just type normally:
Summarize the document I just uploaded.
DMs are useful for private questions, quick document checks, or testing before inviting Clark into a team channel.
Channels
In a channel, Clark stays quiet until mentioned. This keeps busy Slack channels clean.
Good channel requests:
@Clark summarize today's discussion and list open questions.
@Clark turn the last decision into tasks.
@Clark what do we know about Acme from this channel?
Threads
If you ask Clark inside a thread, Clark replies in the same thread. Use threads for document reviews, long summaries, or follow-up questions so the main channel does not become noisy.
Slash Commands
Slash commands are shortcuts. They are useful when you do not want to write a full prompt.
| Command | Use it for |
|---|---|
/clark <message> | Ask Clark directly from Slack. |
/tasks | List tasks in the current channel. |
/tasks all | List tasks across connected chats. |
/summary | Generate a daily channel digest. |
/summary week | Generate a weekly channel digest. |
/summary all | Generate a cross-chat digest. |
/memory | Show remembered entities for the channel. |
Automatic Summaries
Workspace admins can enable automatic summaries in the dashboard chat settings. Clark creates a daily /summary from Monday to Thursday at the local end-of-day time only when the channel had messages in the previous 24 hours. Every Monday at 10:00 in the CEO/admin timezone, Clark creates /summary week for the previous week. Results can be posted to Slack or routed privately to the CEO/admin, and are saved in Memory.
Supported Slack Files
Clark can process:
- PDF, DOCX, XLSX, CSV, TXT, and similar office files;
- images with text, screenshots, receipts, whiteboards, and photos;
- audio files such as MP3, WAV, OGG, M4A, and WebM.
Document results can include type detection, summary, extracted entities, document history, and reusable memory for later tasks.
What To Tell Your Team
Send this message in your first Clark channel:
Clark is our AI assistant. Mention @Clark when you need a summary, task list, document check, remembered fact, or customer note. It will stay quiet unless we call it.
For Workspace Admins
If your Slack app is installed manually instead of through the Clark dashboard, the app should receive Slack events and slash commands through Clark's backend. Most teams do not need this section; use the dashboard installation flow when available.
