Slack

Overview

With Cosine’s Slack integration, you can launch tasks directly from your Slack workspace by simply mentioning @Cosine. Start tasks, colloborate interactively, and get answers in real time — all without leaving Slack, so your team can stay seamlessly in-flow with its existing workflow

Configure

Cosine is now available as a first-class AI app in Slack, fully leveraging Slack’s new AI surfaces (top-bar entry, split-view container, Chat & History tabs).

To get started:

1. Navigate to the Integrations page in your Cosine team
2. Select Slack from available integrations
3. Click Enable to start the authorization process
   • Workspace Authorization: You’ll need to authorize your Slack workspace. You have to be a workspace admin to enable permissions
   • Personal Account Linking: We strongly recommend linking your personal Slack account as well. This enables Cosine
   • tasks to be directly assigned to you.

NOTE: A Slack workspace can only be integrated with one Cosine team at a time.

How it works

You can use Cosine in Slack in two ways:

1. @Cosine in Channels and DMs

Once your Slack workspace is successfully integrated:

• Mention Cosine: In any channel Cosine has been invited to, type @Cosine followed by your request.
• Thread context: If you invoke Cosine inside a thread, it will pull the entire thread into context for richer, more accurate task creation.
• Single-message context: If it’s a one-off message, only that message is used.

2. Chat-Based Working Sessions

Cosine now also lives in Slack’s split-view conversational UI under Apps & AI Agents, so you can now iterate on tasks in real time.

Configure:

If you don’t immediately see Cosine in the top navigation bar:

1. Open your Slack preferences:
   1. macOS: Slack menu > Settings
   2. Windows/Linux: Avatar > Settings
2. Under Navigation, scroll to App agents & assistants header and enable Cosine.

Tip (recommended)

Workspace admins can enable Cosine for everyone at once:

1. In Slack’s desktop app, click the admin settings icon -> select Apps and workflows

2. Next, under Installed apps, select the Cosine app

3. Lastly, select App settings, and under Show Cosine on Slack’s top bar click the Edit button. This will open up a modal allowing you to enable

NOTE: After changing either setting, you’ll need to close and relaunch Slack to see the new icon and functionality.

How it works:

When you message Cosine, a short task-setup form appears, prompting you to:

• Select the project to start your task in.
  • If your team has only one project, Cosine automatically assigns tasks to it, ensuring a frictionless experience.

Once configured, your conversation with Cosine continues directly within Slack, allowing back-and-forth interaction and immediate feedback. View all interactions in the History tab.

Commands and task settings:

Task settings apply per task and can be adjusted anytime within the conversation:
