Feature Comparison
Cosy
Automated Onboarding Sequences
Create and automate up to 10 distinct welcome DM sequences for new members, sent from you, a team member, or the Cosy bot. Fully customize messages with names, links, and emojis, and set precise time delays—from immediately to months in the future. This ensures every new joiner feels welcomed personally, even if they join in the middle of the night, saving you hours of manual outreach and follow-up while ensuring no one is ever missed.
Smart Member Introductions
Grow engagement by automatically introducing opted-in community members to each other via DMs on a customizable cadence. Set the frequency (every 1-4 weeks), weekday, and time. Introductions happen in a 3-person DM with the Cosy bot, and members are randomly matched to enhance serendipity while avoiding recent connections. This feature fosters meaningful 1:1 connections on autopilot, turning a group of individuals into a tight-knit network.
Searchable Member Directory
Build a simple, searchable directory of all your community members without anyone leaving Slack. Create custom profile fields (text, single-select, or multi-select) and notify members to fill them out via a bot DM. Members can then search for keywords and filter profiles directly within Slack using the Cosy app or a /member-directory slash command, making it easy for people to find and connect with the right peers.
Content Highlights & Moderation
Instantly surface your community's most valuable conversations with simple 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 you spot posts needing attention. Cosy also helps maintain a safe environment by allowing you to instantly flag abusive or spam messages for quick moderation action.
