Feature Comparison
Cosy
Automated Onboarding Sequences
Stop manually DM'ing every new face that pops in. Cosy lets you set up to 10 different welcome DM sequences that fire off automatically when someone joins. You can make them come from you, a team member, or the Cosy bot itself. Fully customize the messages with their name, links, emojis—the whole shebang—and schedule them to send immediately or on a delay (think hours, days, or even months later). New member joins at 3 AM? They still get a warm welcome. It's the set-it-and-forget-it magic that saves you hours.
Member Introductions (The Connector)
Wanna spark those random, cool connections that make a community pop? Cosy's intro feature is your wingman. It automatically pairs up opted-in members in a 3-person DM (the two members and the Cosy bot) on a schedule you choose—every week, every month, you name it. It randomizes the matches to keep things fresh and avoids repeating recent intros. You get to customize the intro message template, pick the day and time, and then watch as your members start networking without you lifting a finger.
Searchable Member Directory
Forget clunky external databases or spreadsheets. Cosy builds a slick, searchable member directory right inside Slack. You create custom profile fields (up to 10 of them, with text or multiple-choice options), then nudge all your members to fill them out with one click. Members can use a slash command or the Cosy app to search for people by keywords or skills. It’s the easiest way to help your community members find the right person to ask for help, collaborate with, or just chat with.
Content Highlights & Moderation Alerts
Never let a banger post go unnoticed again. Cosy gives you instant slash-command superpowers to surface the good stuff. Use /most-engaged-messages to find the top 10 posts in a channel, or /most-engaged-messages-all to see what's trending across the whole workspace. You can also find /unreplied-messages to spot questions that got missed. Plus, it helps you keep the space safe by instantly flagging abusive or spammy messages, so you can moderate without constantly scrolling.

Frequently Asked Questions
Cosy FAQ
How does the onboarding automation work?
When a new member joins your Slack, Cosy can automatically send them a sequence of welcome DMs. You create up to 10 different message sequences that can come from you, a teammate, or the Cosy bot. You control the timing (send now or delay it), personalize the messages, and add emojis or links. It runs completely on autopilot, so you save time and no one gets a cold shoulder.
Are the member introductions random?
Yes, but smart-random! Cosy randomly pairs up community members who have opted into the introductions feature.

You set the frequency (like every week or month) and the time, and Cosy handles the matchmaking to create fresh, serendipitous connections.
Do people have to leave Slack to use the Member Directory?
Nope, that's the beauty of it! The entire member directory lives natively inside Slack. Members can fill out their profile via a DM from the Cosy bot and search for others using a simple slash command (/member-directory) right from any channel. No extra apps, no new tabs, no context switching.
Is there a free plan?
