Feature Comparison

Cosy

Automated Onboarding Sequences

Create and automate up to 10 distinct welcome DM sequences for new members, sent from you, a team member, or the Cosy bot. Fully customize messages with names, links, and emojis, and set precise time delays—from immediately to months in the future. This ensures every new joiner feels welcomed personally, even if they join in the middle of the night, saving you hours of manual outreach and follow-up while ensuring no one is ever missed.

Smart Member Introductions

Grow engagement by automatically introducing opted-in community members to each other via DMs on a customizable cadence. Set the frequency (every 1-4 weeks), weekday, and time. Introductions happen in a 3-person DM with the Cosy bot, and members are randomly matched to enhance serendipity while avoiding recent connections. This feature fosters meaningful 1:1 connections on autopilot, turning a group of individuals into a tight-knit network.

Searchable Member Directory

Build a simple, searchable directory of all your community members without anyone leaving Slack. Create custom profile fields (text, single-select, or multi-select) and notify members to fill them out via a bot DM. Members can then search for keywords and filter profiles directly within Slack using the Cosy app or a /member-directory slash command, making it easy for people to find and connect with the right peers.

Content Highlights & Moderation

Instantly surface your community's most valuable conversations with simple 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 you spot posts needing attention. Cosy also helps maintain a safe environment by allowing you to instantly flag abusive or spam messages for quick moderation action.

WA Reminders

Easily link your WhatsApp account by scanning a QR code on your phone, similar to how WhatsApp Web operates. This hassle-free setup ensures you can immediately start scheduling messages without complicated installations or processes.

Schedule from Google Calendar

WA Reminders allows you to schedule messages directly from Google Calendar events. By simply adding an internationally formatted phone number in the event title or description, you can streamline your reminder system, ensuring no important message goes unsent.

Automatic Contact Synchronization

When scheduling messages from our app, your entire contact list is automatically imported from your phone. This feature eliminates the tedious task of manual entry and ensures you can reach out to your clients effortlessly.

Recurring Message Scheduling

With the ability to set recurring messages, WA Reminders saves you the time and effort of rescheduling reminders manually. This feature is particularly beneficial for regular appointments, ensuring your clients never miss a session.

Frequently Asked Questions

Cosy FAQ

How does Cosy handle data privacy and security?

Cosy is a native Slack app, which means it operates within Slack's robust security and compliance framework. It only accesses the data and permissions you explicitly grant during installation. All data is processed securely, and you maintain full control over your community's information. You can review the specific scopes and permissions before installing the app.

Can I customize the messages sent by Cosy?
