Feature Comparison
Cosy
Automated Onboarding Sequences
Cosy automates the initial welcome and integration process for new community members through fully customizable Direct Message (DM) sequences. Community managers can create up to ten distinct onboarding flows, which can be triggered immediately upon a member joining or on a configurable delay. Messages can be personalized with the member's name, include links and emojis, and are sent from either a human team member's account or the Cosy bot. This ensures every new member receives a consistent, warm welcome at any hour, significantly reducing the manual burden on community leaders and preventing any newcomer from being overlooked.
Automated Member Introductions
To foster connections and serendipitous networking, Cosy automatically introduces opted-in community members to each other via DMs on a regular, customizable schedule. Introductions occur in a three-person DM involving the two members and the Cosy bot, with a template message that can be tailored by the admin. The system intelligently pairs members randomly while avoiding recent matches, similar to platforms like Donut. Administrators control the frequency (every 1-4 weeks) and the specific weekday and time (in UTC) for these introductions, systematically driving engagement and relationship-building on autopilot.
Searchable Member Directory
Cosy provides a fully integrated, searchable member directory that operates entirely within Slack, requiring no external apps or logins. Admins can create custom profile fields (up to ten), including text entry and multiple-choice options. Members can be prompted to fill out their profiles via a one-click notification, and new joiners automatically receive a prompt 24 hours after entering the workspace. Members can then search this directory by keyword or filter for completed profiles using a slash command (/member-directory), making it easy to find relevant peers and expertise without leaving the Slack interface.
Content Highlights & Moderation Tools
This feature empowers community managers to surface valuable content and monitor conversations efficiently. Using slash commands, admins can instantly retrieve the top 10 most engaged posts within a specific channel (/most-engaged-messages) or across all public channels (/most-engaged-messages-all). Additionally, the tool can list public messages that have received no replies (/unreplied-messages), helping to identify discussions that may need a boost. Cosy also includes instant flagging for abusive or spam messages, providing essential moderation capabilities to maintain a healthy and respectful community environment.

Frequently Asked Questions
Cosy FAQ
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 that can include the member's name, links, and emojis. These messages can be sent immediately or on a delay (minutes, hours, or even months later) and can appear to come from your account, a team member's account, or the Cosy bot. This ensures every new member is properly welcomed and onboarded without any manual effort, even outside of business hours.
Can members reply to automated messages?
Yes, but it depends on the sender configuration. If the onboarding or introduction messages are sent from a human team member's Slack account, recipients can reply directly as they would in a normal DM conversation. However, if the messages are configured to be sent from the Cosy bot, the bot is currently designed not to respond to replies. This allows for human-like interaction when desired while maintaining clarity when communication is purely automated.
How does the member directory get populated?
Community managers can notify all existing members to create their profiles with a single click, sending a DM prompt via the Cosy bot. Additionally, Cosy automatically sends a profile-editing prompt to every new member 24 hours after they join the Slack workspace. Members simply click 'Edit Profile' in the DM to fill out the custom fields you have set up, which can include text, single-select, or multi-select options. This dual-trigger system ensures high directory participation with minimal administrative effort.
Is there a free plan available?
Yes, Cosy offers a free plan that supports communities with up to 250 members. This allows smaller groups or teams to access core features and evaluate the tool's impact. For communities requiring unlimited members, Cosy provides a 30-day free trial of its paid plans, allowing full access to all features before any commitment is required. This tiered approach makes it accessible for communities of all sizes to begin enhancing their Slack engagement.
