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.
