About Cosy

Imagine your Slack workspace, not just as a hub for work, but as the vibrant, beating heart of a true community. A place where new members feel instantly welcomed, connections spark effortlessly, and the best conversations are always within reach. This is the journey Cosy enables. Cosy is a powerful, Slack-native platform designed to transform your standard Slack workspace into a thriving, engaged, and self-sustaining community. It's built for community managers, founders, and leaders who believe in the power of human connection but are stretched thin by the manual tasks of onboarding, member introductions, and content curation. Cosy automates the heavy lifting, saving you hours every week, so you can focus on strategy and meaningful interactions. Its core value proposition is simple: foster deeper engagement and serendipitous connections directly within the tools your members already use every day, without anyone ever needing to leave Slack. From automated welcome sequences that never sleep to a searchable member directory and smart content highlights, Cosy wraps your community in the warmth and efficiency needed to grow organically and authentically.

Features of Cosy

Automated Onboarding Sequences

Craft the perfect first impression with up to 10 distinct, automated welcome DM sequences. Set them to trigger the moment a new member joins or on a custom delay—minutes, hours, or even months later. You can personalize messages with the member's name, links, and emojis, and choose to send them from yourself, a team member, or the Cosy bot. This ensures every newcomer feels personally welcomed and informed, 24/7, freeing you from the repetitive task of manual greetings and follow-ups, no matter the time zone or hour they arrive.

Smart Member Introductions

Foster meaningful one-on-one connections by automatically introducing opted-in community members to each other via direct message. You control the cadence—every 1, 2, 3, or 4 weeks—and can customize the introductory message. Introductions happen in a 3-person DM with the Cosy bot, allowing you to jumpstart the conversation. The system intelligently pairs members randomly to enhance serendipity while avoiding recent matches, mimicking popular tools like Donut but operating seamlessly within your Slack environment to grow engagement on autopilot.

Slack-Native Member Directory

Build a rich, searchable directory of your community members without anyone leaving Slack. Create custom profile fields (text, single-select, or multi-choice) and prompt members to fill them via a simple notification. Members can then search for keywords and filter profiles directly within Slack using the /member-directory command. This turns your Slack member list into a powerful networking tool, helping people find the right expertise, shared interests, and collaborators effortlessly, strengthening the community fabric.

Content Highlights & Moderation

Instantly surface the most valuable content and maintain a safe space with powerful slash commands. Use /most-engaged-messages to find top posts in a channel or across all public channels, and /unreplied-messages to discover conversations needing attention. Simultaneously, Cosy's moderation tools work in the background to instantly detect common spam techniques like duplicate posts and flag abusive language, helping you maintain a positive and respectful community environment with minimal manual oversight.

Use Cases of Cosy

Scaling a New Community

For founders launching a new Slack-based community, Cosy is the essential co-pilot. It automates the critical "first 90 seconds" for every new member with warm, automated onboarding DMs, ensuring no one falls through the cracks during rapid growth. The automated member introductions quickly build a dense web of connections, making the community feel active and intimate from day one, even with a small initial team managing hundreds of members.

Revitalizing an Established Workspace

Community managers overseeing a large, existing Slack workspace can use Cosy to inject new energy and rediscover value. The Member Directory unlocks hidden connections by making member skills and interests discoverable. Content Highlights slash commands allow managers to quickly identify and amplify the best discussions or rescue unanswered questions, demonstrating active stewardship and re-engaging lurkers with high-quality conversations.

Running Member-Driven Networks

For professional networks, alumni groups, or industry associations where peer connection is the primary value, Cosy's automated introductions are transformative. By consistently facilitating serendipitous 1:1 conversations between members based on shared membership alone, it drives the networking outcomes members crave, leading to higher retention rates and perceived value without constant manual intervention from organizers.

Ensuring Consistent Community Safety

Moderators of large, open, or public communities can leverage Cosy's automated moderation to maintain standards effortlessly. The instant detection of duplicate posts (a classic spam tactic) and abusive language acts as a first line of defense, flagging issues for review. This allows human moderators to focus on nuanced community building and complex situations, rather than constantly policing for basic infractions.

Frequently Asked Questions

How does the automated onboarding work?

When a new member joins your Slack workspace, Cosy triggers a pre-configured sequence of welcome DMs. You can create up to 10 unique sequences with fully customizable messages and scheduling delays (e.g., send a welcome immediately, a resource guide after 1 hour, and a check-in after 1 week). The messages can be sent from you, a team member, or the Cosy bot, ensuring a personal touch is maintained automatically.

Are member introductions opt-in?

Yes, member introductions are entirely opt-in. Community members must choose to participate in the connection program. For those who opt-in, Cosy automatically pairs them with another member on a regular cadence you set (every 1-4 weeks) and facilitates an introduction in a 3-person DM, helping to grow connections organically and respectfully.

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 direct link. Inside the directory, they can search for specific keywords and filter to show only profiles that have been filled out, making it easy to find people with relevant skills or interests.

What does Cosy cost to use?

Cosy offers a free plan for communities with up to 250 members. For larger communities, there is a paid plan with a 30-day free trial for unlimited members. This allows teams of any size to start transforming their Slack community without an upfront financial commitment and scale their usage as their community grows.
