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](https://app.devin.ai/settings/connections/slack) 2. On the **Integrate Devin with Slack** card, click **Connect** Slack connect 3. You’ll be prompted to install the Devin app for Slack in your workspace 4. Back on the Slack settings page, the connected workspace shows a "Slack is connected. Link your user profile" banner — click **Link user profile**. Every user in your organization needs to complete this step once to use Devin from Slack. Slack link user profile 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](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 Devin will respond in-thread to your session. Now, you can communicate back and forth as you would in the regular chat interface. To see it in action, watch [Devin tackle a bug in Slack](/tutorial-library/slack-bug-fix). Slack Chat *Note that Devin may make mistakes. Please double-check responses.* ### Inline Slack Keywords & Functions | Keyword | Function | | - | - | | `!ask` | get a quick codebase answer without starting a full agent. Must come first in the message, right after `@Devin` | | `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)](/work-with-devin/data-analyst) session for database queries, data analysis, and visualizations | | `!fast` | start the session in Fast Mode for quicker responses on simpler tasks | | `!ultra` | start the session in Ultra Mode for the most complex tasks | | `!lite` | start the session in Lite Mode | | `!fusion` | start the session in Fusion Mode | | `!swe`, `!swe2` | start the session on Cognition's latest SWE model (SWE-2 where available) | | `!normal` | switch an active session back to the default Devin mode | | `!new` | force the session to start in a new thread — or, where [code channels](#code-channels) are enabled, in a dedicated channel — 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) | | `!mac` | run the new session on a macOS VM (requires the macOS entitlement for your organization) | | `!outpost ` | run the new session on one of your [Outposts](/cloud/outposts/overview#starting-sessions-on-an-outpost) — by exact name, unique prefix, or ID. `!outpost` alone lists the outposts you can use | | `!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](#sync-sessions-with-slack-threads)) | | `![macro_name]` | Attach a playbook to a Session by referencing its Macro name | Apart from `!ask`, bang commands (`!fast`, `!lite`, `!ultra`, `!fusion`, `!swe`, `!swe2`, `!normal`, `!new`, `!channel`, `!windows`, `!mac`, `!outpost`, `!dana`, `!data`) 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](/work-with-devin/data-analyst) 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](/product-guides/using-playbooks), 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](/onboard-devin/environment/blueprint-reference) change, the Slack message includes the proposed diff and an **Apply** button so you can accept it without leaving Slack. ### Code channels A **code channel** is a Slack channel dedicated to a single Devin session. Instead of following the run in a thread, you get a channel whose name tracks the session title, a status chip showing whether Devin is working / blocked / done, a link back to the session in the webapp, chips and tabs for the pull requests it opens, and a live worklog of the thoughts and tool calls behind each message. Every message you send in the channel goes to that session — no `@Devin` mention needed. There are two ways a session ends up in a code channel: * **Start it there with `!new`.** `@Devin !new ` creates the channel and runs the session in it from the beginning. A `!new` from inside a code channel spawns a separate sibling channel for the new session. * **Let Devin move the conversation.** When a thread conversation turns into real work, Devin can move the session into a code channel itself. The original thread keeps its history and gets a "This session moved to #channel" notice; the session continues in the new channel, and further replies in the old thread no longer reach it. Devin won't move a session whose Slack sync you turned off (see [Sync sessions with Slack threads](#sync-sessions-with-slack-threads)). You can also create the channel from Slack's own affordance on a message. The first message in an empty code channel becomes the task that starts the session — and if Devin isn't a member of the conversation the channel was spawned from, it says so in the channel, since the quoted message is all the context it has. Code channels are enabled for every Devin organization. They also depend on Slack's own Code Channels feature, which Slack is rolling out to workspaces gradually — if you don't see them yet in your workspace, that rollout is still in progress and nothing needs to be enabled on Devin's side. ### Automations triggered from Slack [Automations](/product-guides/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](/product-guides/automations) for setup. ### 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. Channel ### 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. Rename ### Pricing If you don't yet have a Devin account, you can learn more about pricing and plans [here](https://devin.ai/pricing). 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. ### Privacy Our privacy policy is available [here](https://cognition.com/privacy-policy). ### Permissions Details | Permission | Description | Rationale | | - | - | - | | `app_mentions:read` | View messages that directly mention @Devin | Devin is summoned by @mention, so it has to receive mention events | | `assistant:write` | Act as an AI assistant in the Slack sidebar | Powers the AI assistant sidebar experience and its status updates | | `chat:write, chat:write.customize` | Send messages as @Devin or using a customized username and avatar | Devin has to be able to respond to user requests | | `commands` | Add shortcuts and/or slash commands that people can use | Powers `/ask-devin`, `/dana`, and the message shortcuts | | `files:read, files:write` | Upload, edit, and delete files as Devin | Devin needs to manage files in order to send and receive attachments to/from the user | | `channels:history, groups:history, im:history` | View messages and other content in channels, groups, and DMs that Devin is in | Devin has to access historical messages when it is launched inside of a message thread in order to retrieve the previous messages in the thread as context | | `channels:read, groups:read, mpim:read, im:read` | View basic information about channels, private channels, group DMs, and DMs Devin has been added to | Devin needs to resolve and list the channels it can post in (for example the channel picker and `!channel`) | | `channels:join` | Join public channels in a workspace | Lets Devin add itself to public channels configured for automations and incident response | | `im:write` | Start direct messages with people | Devin needs to be able to initiate DMs in order to send users notifications via Slack | | `reactions:read, reactions:write` | View, add, and edit emoji reactions | Devin adds emojis to messages to mark runs as completed or failed, and reactions can trigger automations | | `team:read` | View basic information about the workspace | Devin needs to map a Slack workspace to the right Devin organization | | `users:read, users:read.email`, `users.profile:read` | View people in a workspace as well as their emails and profiles | Devin needs to be able to match Slack users with Devin users based on their email address | We occasionally add scopes as Devin gains Slack capabilities. If your workspace's install is missing a required scope, Devin prompts an admin to reinstall the app from [Settings > Connections > Slack](https://app.devin.ai/settings/connections/slack).
