Slack

Chat and collaborate with Devin directly in your company Slack

Tag @Devin in Slack as soon as bugs, feature requests, and questions come in. Devin responds in-thread with updates and questions when it’s tagged.

Get started

Installation

1. Go to Settings > Connections > Slack
2. Click “Connect”
3. You’ll be prompted to install the Devin app for Slack in your workspace
4. Make sure to link your individual user. All users in your organization will need to complete this step to use Devin.
5. Tag @Devin in Slack to start a session

Note: If your user account is not properly connecting, ensure that your Slack email is the same as your email in https://app.devin.ai/settings. If not, please authenticate the correct email on Slack.

How to use Devin from Slack

Once you’ve installed the Devin integration for Slack, simply trigger Devin with @Devin in any channel. You may include attachments to your message.

Devin will respond in-thread to your session. Now, you can communicate back and forth as you would in the regular chat interface.

Note that Devin may make mistakes. Please double-check responses.

Inline Slack Keywords & Functions

Keyword	Function
!ask	begin your message with !ask to get a quick codebase answer without starting a full agent
!deep	get a deeper research answer using advanced search
mute, @Devin mute	prevents Devin from seeing further Slack messages in thread. Natural phrasings also work (e.g. “be quiet”, “stop responding in this thread”)
unmute, @Devin unmute	reverses the above (also “start responding again”)
(aside), !aside	causes Devin to ignore the message (useful for commenting on Devin’s run directly in-thread)
sleep	puts Devin to sleep; to wake Devin up, send any message in the thread
archive, @Devin archive	puts Devin to sleep + archives the session
EXIT	ends the session
!dana	starts a Data Analyst (Dana) session for database queries, data analysis, and visualizations
!fast	begin your message with !fast to start the session in Fast Mode for quicker responses on simpler tasks
!ultra	begin your message with !ultra to start the session in Ultra Mode for the most complex tasks
!lite	begin your message with !lite to start the session in Lite Mode
!fusion	begin your message with !fusion to start the session in Fusion Mode
!swe	begin your message with !swe to start the session on SWE-1.7
!normal	begin your message with !normal to switch an active session back to the default Devin mode
!new	force the session to start in a new thread instead of replying in the current one
!channel #channel-name	post the session’s reply thread in a different channel (Devin must already be in it)
!windows	run the new session on a Windows VM (requires the Windows entitlement for your organization)
!data	alias for !dana
!discovery	only valid right after !dana / !data — catalogs the databases and schemas reachable through your connected MCP integrations
unsync, !unsync	stop syncing the session to the Slack thread (see Sync sessions with Slack threads)
![macro_name]	Attach a playbook to a Session by referencing its Macro name

Bang commands (!fast, !lite, !ultra, !fusion, !swe, !normal, !new, !channel, !windows, !dana) are recognized anywhere in your message, not just at the beginning — @Devin fix the bug !ultra !new works the same as @Devin !ultra !new fix the bug. They can be stacked in any order, and the keywords themselves are stripped from the prompt Devin receives. A bang command inside an inline or fenced code span is treated as literal text. Sending a mode keyword in an active Devin thread switches that session’s mode mid-session.

Slash commands

Command	What it does
/ask-devin [your question]	Quick codebase answer, without starting a full session. Devin replies in a new thread.
/dana [your data question]	Starts a Dana data-analysis session.

Run either command with no arguments (or with help) to get usage instructions back privately.

Message shortcuts

Right-click (or use the ⋮ overflow menu on) any Slack message to act on it without retyping it:

• Ask Devin about this — uses the message as the question for a quick codebase answer, same as /ask-devin.
• Create a new session — opens a modal pre-filled with the message text, where you pick the channel to post the session in, optionally attach a playbook, and edit the prompt before submitting.

Sync sessions with Slack threads

Sessions can sync bidirectionally with a Slack thread: messages you send in the webapp appear in the thread, and replies in the thread reach Devin. This means you can start a session anywhere and keep your team in the loop.

• Use the Slack toggle in the session composer to turn sync on or off for that session. The icon is colored when synced and greyed out when not.
• The first time you sync to a channel, Devin offers to make it your default so new sessions sync there automatically.
• Send unsync (or !unsync) in a synced thread to immediately stop syncing that session. Toggle sync back on in the webapp to resume.

A couple of related behaviors:

• Mentioning @Devin in the thread of an archived session unarchives it so you can continue the conversation.
• When Devin suggests an environment configuration change, the Slack message includes the proposed diff and an Apply button so you can accept it without leaving Slack.

Automations triggered from Slack

Automations can be triggered by Slack activity — for example a reaction added to a message, or Devin monitoring a channel and jumping in when it can help — and can post run results back to a channel you designate. See the Automations guide for setup.

Turn on Slack Notifications

You can enable Slack notifications for specific runs and Devin will privately message you whenever there’s a status update. To do so, simply click “Enable Slack notifications” in the menu at the top of any run.

Dedicated Devin channel

Set up a #devin-runs channel (or similar) to keep all Devin conversations in one place. This helps your team collaborate on Devin runs together and draw inspiration for different use cases from each other.

How to Rename Devin

You may change Devin’s name in your Slack workspace by going to your Slack Workspace Admin panel -> Configure apps -> Installed Apps -> Devin. Then click on App Details, and go to the Configuration tab of that page. If you scroll down you will find a section called ‘Bot User’ where you may change Devin’s name.

Pricing

If you don’t yet have a Devin account, you can learn more about pricing and plans here.

The AI assistant sidebar experience (app container) requires a paid Slack plan. All other Devin features — @mentions in channels and threads, /ask-devin, /dana, and message shortcuts — work on any Slack plan, including free workspaces.
