Feature Comparison

Cosy

Automated Onboarding Sequences

Stop manually welcoming every new face! Cosy lets you create and automate up to 10 distinct onboarding welcome DM sequences, sent from you, a team member, or the Cosy bot itself. Fully customize messages with member names, links, and emojis, and schedule them to send immediately or on a delay (minutes, hours, or even months later). This ensures every member feels personally welcomed the moment they join, even while you sleep, saving you hours of repetitive administrative work and never dropping the ball on a first impression.

Automated Member Introductions

Foster genuine connections and break the ice on autopilot. Cosy automatically introduces opted-in community members to each other via DMs on a regular cadence you control (every 1-4 weeks). Introductions happen in a 3-person DM with the Cosy bot, and you can customize the intro message. It randomly matches members to enhance serendipity while avoiding recent matches, effortlessly growing engagement and helping your community members build their networks without any manual effort from you.

Slack-Native Member Directory

Build a living, searchable directory of your community without anyone ever leaving Slack. Create custom profile fields (text, single-select, or multi-choice) and notify all members to fill out their profiles with one click. New joiners get a prompt 24 hours after arriving. 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 for people to find the right help and connections.

Content Highlights & Moderation Alerts

Instantly surface the best of your community and stay on top of conversations. Use quick slash commands to find the top 10 most engaged posts in a specific channel (/most-engaged-messages) or across all public channels. You can also instantly flag abusive or spam messages for quick moderation action. This feature helps you celebrate great content, identify trending discussions, and maintain a healthy, positive community environment effortlessly.
