About Cosy

Cosy is a sophisticated Slack-native platform designed to transform static workspaces into vibrant, self-sustaining communities. It elegantly automates the foundational yet time-consuming tasks of community management, allowing leaders to focus on strategy and human connection rather than administrative overhead. By operating seamlessly within the familiar Slack environment, Cosy eliminates the friction of external tools, keeping engagement high and onboarding simple. The platform is engineered for community builders, managers, and leaders who oversee Slack-based networks—from professional associations and customer communities to internal company groups. Its core value proposition lies in fostering meaningful connections between members, automating personalized welcome sequences, creating a living member directory, and providing intelligent moderation, all while reclaiming hours of manual effort each week. Cosy ensures every member feels welcomed, connected, and valued from the moment they join, cultivating a thriving ecosystem of engagement and collaboration.

Features of Cosy

Automated Onboarding Sequences

Cosy empowers you to craft up to ten distinct, automated welcome DM sequences that trigger the moment a new member joins your Slack. These sequences can be personalized with the member's name, links, and emojis, and scheduled to send immediately or on a delayed timeline—minutes, hours, or even months later. You can choose to send messages from yourself, a team member, or the Cosy bot, ensuring a warm, human touch or a streamlined automated approach. This feature guarantees consistent, timely welcomes around the clock, ensuring no new member is ever overlooked, while saving you countless hours of manual outreach and follow-up.

Intelligent Member Introductions

Foster serendipitous connections by automatically introducing opted-in community members to each other via direct message. Cosy manages these introductions on a customizable cadence—every one to four weeks—at a day and time of your choosing. Introductions are made within a three-person DM including both members and the Cosy bot, complete with a customizable template message to kickstart the conversation. The system intelligently pairs members at random while avoiding recent matches, mimicking the serendipity of tools like Donut but within your dedicated community space, thereby systematically growing engagement and network density.

Native Member Directory

Build a rich, searchable directory of your community members without ever leaving Slack. Create custom profile fields—including text entry and multiple-choice options—and prompt members to fill them via a simple notification. Members can then search for keywords and filter profiles directly within Slack using a slash command or the Cosy app. This creates a powerful internal resource where members can find peers with specific skills, interests, or backgrounds, dramatically enhancing discoverability and strengthening the community fabric through better mutual understanding.

Content Insights & Moderation

Gain immediate visibility into your community's pulse with powerful slash commands that surface the top ten most engaging posts or highlight unreplied messages across any channel. Simultaneously, Cosy proactively safeguards your community by instantly detecting duplicate posts—a common spamming technique—and flagging abusive language. This dual functionality provides leaders with the tools to celebrate high-quality contributions and efficiently mitigate risks, maintaining a safe and valuable environment for all members without constant manual monitoring.

Use Cases of Cosy

Scaling Personalized Onboarding for Large Communities

For communities experiencing rapid growth, manually welcoming each new member becomes impossible. Cosy automates this process with personalized, multi-step DM sequences that make every individual feel personally acknowledged. Community managers can set up sequences that deliver essential resources, set expectations, and invite further conversation, ensuring a high-quality onboarding experience at any scale while freeing up leadership to engage in deeper, strategic discussions.

Facilitating Networking and Peer Connections

In member-based organizations or professional networks, the value is often in the connections between members. Cosy’s automated introduction system actively facilitates these valuable peer-to-peer relationships on a set schedule. This transforms a passive member list into an actively networking community, increasing retention and perceived value as members consistently form new, relevant connections without manual intervention from the community team.

Building an Accessible Internal Knowledge Hub

Companies using Slack for internal communication can leverage Cosy’s Member Directory to create a dynamic skills and expertise database. By having employees fill out profiles with their projects, skills, and interests, team members can quickly find internal subject matter experts, fostering cross-departmental collaboration and reducing silos. The searchable directory turns Slack into a powerful internal resource platform.

Maintaining Community Health and Quality

For public-facing communities, maintaining a positive and spam-free environment is paramount. Cosy’s moderation tools allow community managers to quickly identify and address spam through duplicate post detection and to curb negative interactions by flagging abusive language. Concurrently, the content highlights feature allows leaders to recognize and amplify positive contributions, encouraging quality discourse and reinforcing community standards effortlessly.

Frequently Asked Questions

How does the automated onboarding work?

When a new member joins your Slack workspace, Cosy automatically triggers a pre-configured sequence of direct messages. You can create up to ten unique sequences with fully customizable messages and scheduling delays. The messages can be sent from your own account, a team member's account, or the Cosy bot. If sent from a human account, the new member can reply directly as in a normal conversation. This ensures every member receives a timely, personalized welcome without any manual effort from your team.

Can members opt-out of automatic introductions?

Yes, the member introduction feature is entirely opt-in. Community members will only be automatically introduced to each other if they have chosen to participate. During the setup, you can configure how members are invited to opt-in. Furthermore, Cosy's algorithm intelligently avoids matching members who have been recently introduced, ensuring a fresh and varied networking experience for participants over time.

Where can members access the searchable directory?

Members can access the directory in two ways. They can open the Cosy app directly within Slack, or they can use the /member-directory slash command in any public channel to receive a quick link to it. The directory itself is fully searchable and filterable, allowing members to find others based on keywords or specific profile fields that have been completed, all without leaving the Slack interface.

What does Cosy cost to use?

Cosy offers a free plan for communities with up to 250 members. For larger communities or access to all premium features, a 30-day free trial is available for the unlimited members plan. After the trial, paid plans begin at a competitive rate, positioning Cosy as a more affordable and Slack-integrated alternative to similar platforms on the market. Specific pricing tiers can be found on the Cosy website.
