Feature Comparison

Cosy

Automated Onboarding Sequences

Cosy allows community managers to create and automate up to ten distinct welcome DM sequences for new members, eliminating the need for manual greetings. These sequences can be triggered immediately upon joining or on a customizable delay, and can be sent from the community leader, a team member, or the Cosy bot itself. Messages are fully customizable with member names, links, and emojis, ensuring a personal touch. This feature guarantees that every new member, regardless of when they join, receives a warm welcome and crucial information, saving administrators countless hours while ensuring no one is overlooked.

Automated Member Introductions

To foster deeper connections, Cosy automatically introduces opted-in community members to each other via direct messages on a regular cadence. Administrators can customize the frequency (every 1-4 weeks), the day, and the time. Introductions happen in a three-person DM involving the two members and the Cosy bot, with a customizable intro message template. The system intelligently pairs members randomly to enhance serendipity while avoiding recent matches, mimicking tools like Donut but within Slack, to automatically grow engagement and help members build their networks.

Slack-Native Member Directory

Cosy provides a simple, searchable directory of all community members that operates entirely within Slack. Leaders can create custom profiles with up to ten fields, including text entry and multiple-choice options. Members can be prompted to fill out their profiles via a notification from the Cosy bot, either manually by an admin or automatically 24 hours after joining. Members can then search for keywords and filter profiles using the Cosy app or a /member-directory slash command, making it easy to find and connect with the right people without ever leaving the workspace.

Content Highlights & Moderation Tools

This feature helps surface the most valuable conversations and maintain community health. With simple slash commands, admins can instantly retrieve the top 10 most engaged posts in a specific channel (/most-engaged-messages) or across all public channels (/most-engaged-messages-all). Additionally, the /unreplied-messages command surfaces posts that have not received replies, allowing leaders to spark conversation. Cosy also includes instant moderation tools to flag abusive and spam messages, ensuring a safe and positive environment for all members.

This feature allows users to navigate through connections and discover hidden relationships that may not have been apparent, enriching the research experience and understanding of the material.

Built-in Viewer
