Feature Comparison
Cosy
Automated Onboarding Sequences
Imagine welcoming every new member personally, regardless of when they join. Cosy allows you to create and automate up to ten distinct welcome DM sequences that can be sent from you, a team member, or the Cosy bot itself. You have full control, customizing messages with the member's name, links, and emojis, and setting precise time delays—from immediate greetings to follow-ups months in the future. This ensures no one falls through the cracks, providing a warm, consistent first touchpoint that saves you hours of manual effort and makes members feel valued from day one, even while you sleep.
Smart Member Introductions
What if meaningful connections could happen on autopilot? Cosy grows engagement by automatically introducing opted-in community members to each other via direct messages. You customize the cadence—every 1, 2, 3, or 4 weeks—and the introductory message template. Introductions happen in a three-person DM with the Cosy bot, allowing you to jumpstart the conversation. The system randomly pairs members to enhance serendipity while intelligently avoiding recent matches, fostering a web of relationships that strengthens your community's fabric without any manual intervention.
Searchable Member Directory
How do members discover who's who without leaving Slack? Cosy creates a simple, searchable directory right within your workspace. You can define up to ten custom profile fields—from text entries to multiple-choice options—and prompt members to fill them out via a gentle nudge from the Cosy bot. Members can then search for keywords or filter profiles to find the right people, expertise, or interests. This tool transforms your member list from names into known colleagues, making your community more discoverable and tightly knit.
Content Highlights & Moderation
Ever curious which conversations are truly resonating? Cosy surfaces your community's most valuable content instantly with simple slash commands. Use /most-engaged-messages to find top posts in a channel, or /most-engaged-messages-all to see highlights across all public channels. The /unreplied-messages command helps you spot posts needing attention. Furthermore, Cosy helps maintain a healthy environment by instantly flagging potentially abusive or spam messages, allowing you to nurture positive discussions and keep the community space safe and engaging.

Use Cases
Cosy
Scaling Community Onboarding
For growing communities, personally welcoming dozens or hundreds of new members each week is impossible. Cosy automates this critical first impression, delivering timely, personalized welcome messages and resources. This ensures every member receives a consistent, informative, and warm introduction, dramatically improving retention and freeing community leaders to engage in deeper, strategic work instead of repetitive administrative tasks.
Fostering Member-Led Engagement
Passive communities often struggle with low interaction. Cosy actively fosters connections by automatically introducing members with shared interests or complementary roles. This creates a self-perpetuating cycle of engagement where members build their own networks, start new conversations, and collaborate, reducing the burden on moderators to constantly spark discussion and leading to a more vibrant, member-driven ecosystem.
Building a Discoverable Network
In large Slack workspaces, valuable expertise and connections remain hidden. Cosy’s member directory solves this by making every member’s skills, interests, and roles searchable. A new member looking for a mentor, a founder seeking beta testers, or a developer needing advice can quickly find the right person, transforming your Slack from a chat app into a powerful, internal networking and knowledge-sharing platform.
Identifying & Amplifying Quality Content
Great insights can get lost in busy channels. Community managers can use Cosy’s content highlight features to easily identify the most engaging discussions, insightful questions, or popular announcements. This allows them to amplify this quality content, recognize contributing members, and guide future conversations, ensuring the community's best ideas get the visibility they deserve and set a positive tone for interaction.

Frequently Asked Questions
Cosy FAQ
How does the automated onboarding work?
When a new member joins your Slack workspace, Cosy can automatically send them a sequence of direct messages according to your configuration. You can create up to 10 distinct sequences with fully customizable messages and set time delays—from immediately to minutes, hours, or even months later. The messages can appear to come from you, a team member, or the Cosy bot, ensuring a personalized welcome for every joiner, 24/7.
Are member introductions opt-in?
Yes, member participation in the automated introductions feature is entirely opt-in. Community members must choose to be part of the matching pool. For those who opt in, Cosy will introduce them to another randomly selected member on a cadence you set (e.g., every 1-4 weeks), while avoiding recent matches to ensure fresh connections.
Where can members access the Member Directory?
Members can access the searchable directory in two ways: by opening the Cosy app within Slack or by using the /member-directory slash command in any public channel. This command provides a quick link to the directory, allowing members to easily search for others based on profile keywords or filter for completed profiles.
What happens if a member replies to an automated DM?
If your onboarding or introduction messages are configured to be sent from you or a team member (not the Cosy bot), the recipient can reply just like in a normal DM conversation, and you will receive their reply in your Slack DMs. If messages are sent from the Cosy bot, the bot does not currently respond to replies, keeping the interaction simple and straightforward.
