Feature Comparison
Cosy
Automated Onboarding Sequences
Cosy automates up to 10 distinct welcome DM sequences for new members, triggered immediately upon joining or on a configurable delay. This feature allows for fully customizable messages, including personalization with the member's name, links, and emojis. Sequences can be sent from a community leader, a team member, or the Cosy bot, ensuring consistent, 24/7 onboarding that saves hours of manual outreach and follow-up. This guarantees no new member is overlooked, even outside business hours, setting the tone for immediate engagement.
Intelligent Member Introductions
This feature grows community engagement by automatically introducing opted-in members to each other via direct message on a customizable cadence (every 1-4 weeks). Introductions are made in a 3-person DM including both members and the Cosy bot, with a customizable template to kickstart conversation. The system intelligently avoids recent matches to maximize serendipitous connections, fostering a network effect and deepening relationships across the community without manual intervention from managers.
Slack-Native Member Directory
Cosy creates a fully searchable member directory that operates entirely within Slack, eliminating the need for external platforms. Community leaders can define up to 10 custom profile fields (text, single-select, or multi-choice) and prompt members to fill them via automated DMs. Members can then use a slash command (/member-directory) to search for peers by keyword or filter by completed profiles, facilitating easy connections based on shared interests, skills, or expertise.
Content Engagement & Moderation Tools
Cosy provides powerful slash commands to surface high-value content and maintain community health. Leaders can instantly retrieve the top 10 most engaged posts in a specific channel or across all public channels. Additionally, the tool can flag unreplied messages to ensure no query goes unanswered. Built-in moderation automatically detects and flags spam and abusive language, creating a safer environment and protecting the community's professional integrity with minimal manual oversight.
