Cosy

Cosy is the essential automation engine for building vibrant, self-sustaining communities directly within Slack. Designed for forward-thinking community managers, startup founders, and team leaders, Cosy eliminates the manual, repetitive workload that stifles growth and engagement. Its core mission is to automate the fundamental pillars of community building—onboarding, connection, discovery, and moderation—so leaders can focus on strategy and scale. By operating natively inside Slack, Cosy seamlessly integrates into your team's existing workflow, saving hours every week while fostering deeper member connections and surfacing actionable insights. From the moment a new member joins, Cosy delivers personalized welcome sequences, even while you sleep. It then continuously works to spark meaningful 1:1 introductions and provides a powerful, searchable member directory to break down silos. Beyond fostering connections, Cosy empowers leaders with tools to automatically highlight top-performing content and instantly flag spam. For any team looking to transform a simple Slack group into a thriving, productive, and cohesive ecosystem, Cosy provides the scalable infrastructure to drive engagement, streamline operations, and ensure every member feels valued from day one.

Automated Onboarding Sequences

Effortlessly welcome every new member with personalized, automated direct messages. Configure up to 10 distinct DM sequences that trigger the moment someone joins your Slack workspace. Fully customize message content, include member names and links, and set precise time delays—from immediate sends to follow-ups months in the future. Sequences can be sent from you, a team member, or the Cosy bot, ensuring a warm, consistent welcome 24/7. This automation saves countless hours of manual outreach and guarantees no new member is ever overlooked, laying the foundation for immediate engagement.

Intelligent Member Introductions

Foster serendipitous connections and grow engagement by automatically introducing community members to each other via DMs. Opted-in members are randomly paired on a customizable cadence—every 1, 2, 3, or 4 weeks—at a time you choose. Introductions happen in a 3-person DM with the Cosy bot, complete with a customizable template message to kickstart the conversation. The system intelligently avoids recent matches, ensuring fresh connections and enhancing the sense of a dynamic, interconnected community where relationships form on autopilot.

Searchable In-Slack Member Directory

Build a rich, searchable knowledge base of your community without anyone ever leaving Slack. Create a custom directory with up to 10 fields (text, single-select, or multi-choice) for members to fill out. Prompt all members to build their profiles with one click, and new joiners automatically receive a profile prompt 24 hours after joining. Members can then search for keywords and filter profiles directly within Slack using the Cosy app or a simple /member-directory slash command, making it easy to find the right people and expertise.

Content Highlights & Moderation

Gain instant visibility into your community's pulse with powerful slash commands. Surface the top 10 most engaging posts in a specific channel or across all public channels to recognize valuable contributions and trending topics. Alternatively, quickly identify unanswered questions or overlooked messages with the /unreplied-messages command. Cosy also provides automated moderation, instantly flagging abusive and spam messages to maintain a safe, positive environment, giving leaders superpowers to guide community health and highlight excellence effortlessly.

Scaling Startup Communities

For fast-growing startups, manually managing a burgeoning Slack community is unsustainable. Cosy automates the critical touchpoints of member onboarding and connection, allowing founders and small teams to scale their community operations effortlessly. By ensuring every new member is welcomed personally and introduced to peers, Cosy helps maintain a high-touch, engaged atmosphere even as member counts soar, turning the community into a powerful asset for product feedback, support, and advocacy without proportional increases in manual effort.

Boosting Engagement for Paid Communities

Community managers of paid memberships or premium Slack groups need to demonstrate clear value to retain members. Cosy directly drives engagement by automating 1:1 introductions, fostering networking that members love. The searchable member directory helps members find collaborators, clients, or mentors, enhancing the perceived ROI of their membership. Automatically highlighting top content also rewards active contributors and sets quality benchmarks, creating a more vibrant and valuable ecosystem that justifies the subscription cost.

Streamlining Internal Team Culture

Beyond external communities, Cosy is perfect for unifying remote or hybrid internal teams. Use automated onboarding sequences for new hires to integrate them smoothly into company culture and channels. Schedule regular intro DMs between employees across different departments to break down silos and encourage cross-functional collaboration. The member directory helps team members quickly find colleagues with specific skills or interests, fostering a more connected, cohesive, and productive organizational culture directly within the company's primary communication hub.

Managing Large-Scale Events or Cohorts

For organizations running cohorts, accelerators, or virtual events, Cosy efficiently manages participant integration. Automate a sequence of welcome and informational DMs as participants join the dedicated Slack workspace. Use scheduled introductions to encourage networking among attendees, maximizing the value of the event. The content highlight feature allows organizers to easily spot and amplify the best discussions and questions from the community, ensuring key insights don't get lost in busy channels.

How does Cosy handle privacy and data?

Cosy operates with a strong commitment to privacy. It only accesses and uses data from your Slack workspace that is necessary to provide its features, such as member profiles and public channel messages for highlights. Introductions are only made between members who have opted into the matching feature. You maintain full control over the data collected for the member directory, and all interactions comply with Slack's platform policies and best practices for data security.

Can I customize the onboarding messages?

Absolutely. Cosy offers deep customization for onboarding sequences. You can create up to 10 different message steps, fully customizing the text, including emojis, links, and personalization tokens like the member's first name. You also have complete control over the timing, setting delays between messages in minutes, hours, or even months, allowing you to design a sophisticated, multi-touch welcome journey tailored to your community's needs.

What happens if a member replies to an automated DM?

If your onboarding or intro DMs are configured to be sent from you or a team member (using a shared workspace token), the recipient can reply just like a normal DM, and the reply will go to that person's Slack inbox. This allows for genuine, human follow-up. If messages are sent from the Cosy bot, the bot is currently designed not to respond to replies, keeping the interaction simple and expectation-free.

Is there a free plan available?

Yes, Cosy offers a generous free tier. You can use Cosy for free for communities with up to 250 members. For communities that need to scale beyond that, there is a full-featured, unlimited members plan that starts with a 30-day free trial, allowing you to test all premium features with your entire community before making any commitment.
