About Cosy

Cosy is a powerful, Slack-native automation platform designed to transform your workspace into a thriving, self-sustaining community. It directly tackles the most time-consuming tasks that community managers face, automating them so you can focus on strategy and genuine human connection. The core value proposition is simple: dramatically increase member engagement and belonging while saving you hours of manual effort every single week. Instead of juggling spreadsheets, manually welcoming members, or trying to force connections, Cosy handles it all within the familiar environment of Slack. It's built for community leaders, founders, and managers who run professional networks, customer communities, or internal teams on Slack and are tired of the administrative grind. By automating personalized onboarding sequences, facilitating serendipitous 1:1 introductions, building a searchable member directory, and highlighting top content, Cosy creates a warmer, more connected, and active community on autopilot. Frankly, if you're managing a community in Slack without a tool like Cosy, you're leaving both member satisfaction and your own precious time on the table.

Features of Cosy

Automated Onboarding Sequences

This is my absolute favorite feature and the first one you should set up. Cosy allows you to create up to ten distinct, automated welcome DM sequences that trigger when a new member joins. You can customize everything: the sender (you, a team member, or the Cosy bot), the message content (with personalization like their name), and the timing (immediately or delayed by minutes, hours, or even months). It ensures every member feels personally welcomed, even at 4:30 AM, saving you from the repetitive task of manual greetings and follow-ups. The ability to have replies go to a human inbox if sent from you is a brilliant touch that maintains authenticity.

Smart Member Introductions

Cosy fosters genuine connections by automatically introducing opted-in community members to each other via DMs on a schedule you control (every 1-4 weeks). It works like a smarter, more integrated version of Donut, creating a three-person DM with both members and the Cosy bot. The matching is random to enhance serendipity but intelligently avoids re-matching people who have recently been introduced. This feature is a game-changer for growing organic engagement and helping members build their network without you lifting a finger after the initial setup.

Slack-Native Member Directory

Forget clunky external directories or static spreadsheets. Cosy builds a fully searchable member profile directory right inside Slack. You can customize up to 10 profile fields (text, single-select, multi-select) and prompt members to fill them out via a simple bot notification. Members can then use a slash command (/member-directory) to search for people by keyword or filter for completed profiles. This creates a invaluable, living resource that helps members find the right people, skills, or interests, all without ever leaving their primary community hub.

Content Highlights & Moderation

Cosy gives you instant visibility into your community's pulse with powerful slash commands. Quickly surface the top 10 most engaging posts in a channel or across all public channels to identify trending topics and celebrate great contributions. Conversely, find unreplied messages to ensure no query goes unanswered. On the safety side, Cosy provides essential moderation by instantly detecting duplicate posts (a common spam tactic) and flagging abusive language, helping you maintain a positive and safe environment with minimal manual oversight.

Use Cases of Cosy

Scaling Personalized Onboarding for New Members

For communities experiencing rapid growth, personally welcoming each new member becomes impossible. Cosy automates this critical first touchpoint, ensuring every single person receives a timely, personalized welcome message sequence. This immediate engagement dramatically increases the likelihood of a new member becoming active and feeling valued from day one, without the community manager facing a crushing time burden.

Increasing Engagement in Stagnant Communities

If your community is quiet with members lurking but not connecting, Cosy's automated introductions are the perfect spark. By proactively connecting members with shared interests or complementary roles via scheduled 1:1 DMs, you create private spaces for conversation to flourish. This often leads to those relationships spilling back into public channels, increasing overall activity and creating a more vibrant, interconnected community feel.

Building a Discoverable Network Within a Large Slack

In large workspaces or communities, it's hard to know who does what. Cosy's member directory solves this by creating a searchable, internal "LinkedIn" directly in Slack. Members can find experts, potential collaborators, or people with specific hobbies. This transforms a chaotic list of names into a valuable professional and social network, unlocking the community's collective knowledge and fostering collaboration.

Proactive Community Health and Safety Management

Instead of constantly monitoring channels for spam or negative behavior, Cosy acts as a first line of defense. Its automated detection of duplicate posts and abusive language allows community managers to address issues quickly, often before they're widely seen. Simultaneously, using the content highlights to surface and celebrate top posts reinforces positive behavior and shows members what great contributions look like, guiding community culture proactively.

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 welcome DMs. You can set up to 10 unique sequences with fully customizable messages that can include the member's name, links, and emojis. You choose the sender (you, a teammate, or the Cosy bot) and schedule the messages to send immediately or on a delay (minutes, hours, or months later). If sent from a human, replies go to that person's DM inbox.

Are member introductions opt-in?

Yes, absolutely. Community members must explicitly opt-in to be part of the automated introductions. This ensures compliance and respects member preferences. Once opted-in, Cosy randomly pairs them with another opted-in member on your chosen schedule (e.g., every two weeks), avoiding recent matches to ensure fresh connections.

Where can members access the directory?

Members can access the searchable member directory in two ways: by opening the Cosy app within Slack or by using the /member-directory slash command in any public channel. The slash command provides a quick link to the directory interface where they can search by keywords or filter for profiles that have been filled in.

What does Cosy's moderation detect?

Cosy's moderation tools are designed to catch common community health issues automatically. It specifically detects duplicate posts, which is a frequent technique used by spammers, and flags messages containing abusive or harmful language based on its internal filters. This gives community managers an instant alert to review and take action, keeping the community safe with less manual monitoring.
