Feature Comparison
Cosy
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.

Cosy FAQ
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.
