Feature Comparison
Cosy
Automated Onboarding Sequences
Create and automate up to 10 distinct welcome DM sequences for new members, sent either from you, a team member, or the Cosy bot. Fully customize messages with member names, links, and emojis, and set precise time delays—from immediately to months in the future. This ensures every new joiner receives a warm, timely welcome, even outside business hours, saving administrators hours of manual outreach and follow-up while ensuring no one is overlooked.
Automated Member Introductions
Grow engagement by automatically connecting community members through direct introductions in DMs. Opted-in members are randomly paired on a customizable cadence (every 1-4 weeks) and introduced in a three-person DM including the Cosy bot. The system avoids recent matches to enhance serendipity. This feature automates the networking process, fostering relationships and building a highly engaged community where connections happen on autopilot.
Slack-Native Member Directory
Build a simple, searchable directory of all community members without ever leaving Slack. Administrators can create custom profiles with up to 10 fields (text, single-select, or multi-select). Members can be prompted to fill out their profiles via automated DMs or a manual nudge. Using a slash command or the Cosy app, members can then search and filter profiles to find the right people, strengthening community ties and discoverability.
Content Highlights & Moderation Tools
Instantly surface the most valuable conversations with 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 identify posts needing attention. Additionally, Cosy provides tools to instantly flag abusive or spam messages, helping maintain a healthy, positive community environment directly within Slack.
WA Reminders
Link WhatsApp with a QR Code
WA Reminders allows users to link their WhatsApp account effortlessly by scanning a QR code on their phone, functioning similarly to WhatsApp Web. This feature provides a simple and quick way to get started with scheduling messages.
Schedule from Google Calendar
Users can conveniently schedule messages directly from their Google Calendar events. By inserting an internationally formatted phone number in the event details, reminders can be sent automatically, ensuring that clients receive timely notifications.
Full Contact List Sync
The application imports the user's entire contact list automatically, making it easy to schedule messages without having to manually enter each contact. This feature saves time and minimizes the chances of errors in contact information.
Recurring Message Scheduling
WA Reminders supports the scheduling of recurring messages, which is particularly beneficial for businesses that rely on regular appointment reminders. This capability ensures that clients are consistently informed about their upcoming appointments without manual intervention.
Use Cases
Cosy
For Scaling Online Communities
Community managers running growing Slack-based groups can use Cosy to automate essential but repetitive tasks. Automated onboarding ensures consistent welcome experiences for hundreds of new members. Simultaneously, automated introductions and a searchable directory help prevent the community from feeling impersonal as it scales, maintaining high engagement and retention rates without proportional increases in manual management time.
For Founder-Led Networks & Startups
Founders building networks for customers, peers, or beta testers can leverage Cosy to foster a tight-knit environment efficiently. The tool allows them to automate initial touchpoints and connections, making members feel personally welcomed and connected from day one. This helps build strong founder-member relationships and a loyal community, which is crucial for feedback, advocacy, and product development, all without the founder being constantly online.
For Professional Associations & Masterminds
Professional groups focused on networking and knowledge sharing benefit greatly from Cosy's structured introduction system and member directory. By automatically facilitating 1:1 connections between members with shared interests (via profile data), Cosy transforms a static Slack into a dynamic networking engine. The content highlight features also allow moderators to easily surface and celebrate insightful discussions, adding value for all members.
For Educational Cohorts & Courses
Instructors and program managers using Slack for course communities can employ Cosy to enhance the student experience. Automated onboarding sequences can deliver crucial resources, schedules, and welcome messages.
