Feature Comparison
Cosy
Automated Onboarding Sequences
Create and automate up to 10 distinct welcome DM sequences for new members, sent either from you, a team member, or the Cosy bot. Fully customize messages with member names, links, and emojis, and set precise time delays—from immediately to months in the future. This ensures every new joiner receives a warm, timely welcome, even outside business hours, saving administrators hours of manual outreach and follow-up while ensuring no one is overlooked.
Automated Member Introductions
Grow engagement by automatically connecting community members through direct introductions in DMs. Opted-in members are randomly paired on a customizable cadence (every 1-4 weeks) and introduced in a three-person DM including the Cosy bot. The system avoids recent matches to enhance serendipity. This feature automates the networking process, fostering relationships and building a highly engaged community where connections happen on autopilot.
Slack-Native Member Directory
Build a simple, searchable directory of all community members without ever leaving Slack. Administrators can create custom profiles with up to 10 fields (text, single-select, or multi-select). Members can be prompted to fill out their profiles via automated DMs or a manual nudge. Using a slash command or the Cosy app, members can then search and filter profiles to find the right people, strengthening community ties and discoverability.
Content Highlights & Moderation Tools
Instantly surface the most valuable conversations with slash commands. Use /most-engaged-messages to find top posts in a channel, or /most-engaged-messages-all for insights across all public channels. The /unreplied-messages command helps identify posts needing attention. Additionally, Cosy provides tools to instantly flag abusive or spam messages, helping maintain a healthy, positive community environment directly within Slack.

Use Cases
Cosy
For Scaling Online Communities
Community managers running growing Slack-based groups can use Cosy to automate essential but repetitive tasks. Automated onboarding ensures consistent welcome experiences for hundreds of new members.

For Professional Associations & Masterminds
Professional groups focused on networking and knowledge sharing benefit greatly from Cosy's structured introduction system and member directory.

The content highlight features also allow moderators to easily surface and celebrate insightful discussions, adding value for all members.
For Educational Cohorts & Courses
Instructors and program managers using Slack for course communities can employ Cosy to enhance the student experience. Automated onboarding sequences can deliver crucial resources, schedules, and welcome messages.
