About Cosy

Cosy is a powerful Slack-native application designed to transform standard Slack workspaces into vibrant, self-sustaining communities. It automates the manual, time-consuming tasks of community management, enabling leaders to foster connection and engagement without constant hands-on effort. The tool is built specifically for community managers, founders, and team leaders who use Slack as their primary community hub and want to enhance member experience, improve retention, and scale their operations efficiently. Cosy's core value proposition lies in its deep integration with Slack, allowing all its powerful features—from automated onboarding to member introductions—to operate seamlessly within the familiar Slack interface. This eliminates the need for members to switch between platforms, creating a more cohesive and "cosy" environment. By automating welcome sequences, facilitating member-to-member connections, providing a built-in directory, highlighting valuable content, and offering moderation tools, Cosy saves administrators hours of manual work each week while systematically growing community health and engagement from within Slack itself.

Features of Cosy

Automated Onboarding Sequences

Create and automate up to ten distinct welcome DM sequences to greet new members the moment they join your Slack workspace. You can configure these messages to be sent from you, a team member, or the Cosy bot, with fully customizable content, links, emojis, and personalized name tags. Schedule messages to send immediately or on a delay (minutes, hours, or even months later), ensuring consistent and timely engagement even while you sleep. If sent from a human profile, members can reply directly, allowing for genuine conversation. This feature replicates complex onboarding automation tools but in a simpler, more affordable package integrated directly into Slack.

Automated Member Introductions

Foster deeper connections by automatically introducing opted-in community members to each other via direct messages. You control the cadence, setting introductions to occur every 1, 2, 3, or 4 weeks on a specific weekday and time. Introductions happen in a three-person DM involving the two matched members and the Cosy bot, with a customizable template to kickstart the conversation. The system intelligently pairs members randomly to encourage serendipity while avoiding recent matches. This automated networking builds engagement and helps members form valuable relationships without manual intervention from community managers.

Slack-Native Member Directory

Build a fully searchable member directory without ever leaving Slack. Administrators can create custom profiles with up to ten fields, including text entry and multiple-choice options. With one click, you can prompt all members to fill out their profiles via a DM from the Cosy bot. Members can then search the directory by keyword and filter for completed profiles using the /member-directory slash command or the Cosy app. This centralized resource helps members discover each other's skills and interests, fostering a more connected and helpful community environment directly within their primary communication platform.

Content Highlights & Moderation Tools

Surface your community's best content and maintain safety with powerful slash commands and automated monitoring. Use /most-engaged-messages to find the top posts in a channel, or /most-engaged-messages-all to see highlights across all public channels. The /unreplied-messages command helps identify posts needing attention. For moderation, Cosy automatically detects duplicate posts (a common spamming technique) and flags abusive language, providing instant alerts to help keep the community safe and high-quality with minimal manual oversight.

Use Cases of Cosy

Scaling Professional Networks & Communities

For paid or professional communities built on Slack, Cosy automates the critical first impression through structured onboarding, ensuring every new member feels personally welcomed and informed about community rules and resources. The automated member introductions facilitate networking among professionals, leading to spontaneous collaborations, mentorship, and business opportunities. The searchable member directory allows members to easily find experts, potential clients, or partners based on their listed skills and roles, directly increasing the community's value proposition.

Boosting Engagement in Large Member-Based Organizations

Non-profits, alumni groups, or large course cohorts with hundreds of Slack members can use Cosy to prevent the community from becoming a passive broadcast channel. By automatically connecting members with shared interests or goals, Cosy transforms a large audience into an interactive network. Community managers can use the content highlight tools to identify and amplify high-value discussions, encouraging more of that behavior, while moderation features help manage the increased volume of interactions efficiently.

Streamlining Onboarding for SaaS & Product-Led Communities

Companies with product-led communities can integrate Cosy to guide new users from sign-up to active participation seamlessly. Automated DMs can deliver tutorial links, invite users to key channels, and gather initial feedback. The member directory helps users find peers facing similar challenges or using complementary features. This structured, automated approach reduces the support burden on the team while increasing user activation, retention, and product advocacy through stronger peer connections.

Maintaining Safe & Valuable Support Forums

For communities centered around support, such as those for developers, creators, or specific software, Cosy helps maintain a high signal-to-noise ratio. The moderation tools automatically curb spam and abuse, protecting the community's helpful atmosphere. Meanwhile, the ability to quickly surface "unreplied messages" allows moderators or eager members to ensure no question goes unanswered, fostering a culture of mutual aid and reliability that keeps members coming back.

Frequently Asked Questions

How does the automated onboarding work?

When a new member joins your Slack workspace, Cosy triggers your pre-configured onboarding sequence. You can set up to 10 messages with custom text, emojis, and links, which can include the member's name for personalization. These messages can be scheduled to send immediately or on a delay of minutes, hours, or months. They can be sent from your profile, a teammate's profile, or the Cosy bot. If sent from a human profile, the new member can reply directly to continue the conversation.

Are member introductions opt-in?

Yes, member introductions are entirely opt-in. Community members must choose to participate in the automated introductions feature. For those who opt in, Cosy will randomly pair them with another opted-in member on a cadence you set (e.g., every week). The system is designed to avoid matching the same people together in quick succession to maximize serendipitous connections within the community.

How do members access and search the Member Directory?

Members can access the directory in two ways: by opening the Cosy app within Slack or by using the /member-directory slash command in any public channel, which provides a quick link. Inside the directory, they can search for specific keywords (like "marketing" or "Python") across all member profiles. They can also filter the view to show only members who have completed their profiles, making it easier to find people with available information.

What does Cosy do when it detects spam or abusive language?

Cosy proactively monitors public channels for duplicate messages (a common spamming technique) and for language flagged as abusive. When such content is detected, Cosy instantly alerts the community administrators or moderators within Slack. This allows the human team to review and take appropriate action quickly, helping to maintain a safe and positive environment without requiring them to constantly read every message.
