Feature Comparison

Cosy

Automated Onboarding Sequences

Save countless hours by automating how you welcome new members. You can create up to 10 distinct welcome message sequences that are sent via Direct Message (DM) when someone joins your Slack. These messages can be scheduled to send immediately or on a delay (minutes, hours, or even months later), and they can be sent from you, a team member, or the Cosy bot. Fully customize the messages with the member's name, links, and emojis to make every welcome feel personal and warm, even if you're asleep.

Automated Member Introductions

Grow engagement naturally by helping your members connect. Cosy can automatically introduce opted-in members to each other in a private, three-person DM (the two members and the Cosy bot). You set the frequency—every 1, 2, 3, or 4 weeks—and choose the day and time. Cosy randomly pairs members to enhance serendipity while avoiding recent matches, and you can customize the introductory message template to kickstart conversations effortlessly.

Searchable Member Directory

Help your community members find and learn about each other without ever leaving Slack. Create a custom directory by selecting up to 10 fields for profiles (like text, single-select, or multi-choice). You can then notify all members to fill out their profiles with one click. New joiners get a gentle nudge 24 hours after arriving. Members can search and filter this directory via the Cosy app or a simple /member-directory slash command.

Content Highlights & Moderation

Instantly surface the most valuable conversations and identify posts that need attention. Use simple slash commands to find the top 10 most engaged messages in a specific channel or across all public channels. You can also quickly pull up a list of public messages that have gone unreplied to, allowing you to jump in and re-ignite discussions. This feature helps you recognize contributors and ensure no great question or idea gets lost in the chatter.

WA Reminders

Seamless WhatsApp Linking

Linking your WhatsApp account is as easy as using WhatsApp Web. You simply scan a QR code with your phone, and you're connected. This secure process means WA Reminders acts as a bridge to schedule messages, but all conversations remain in your official WhatsApp app. You don't need to share passwords or use a separate phone number, keeping your communication personal and secure.

Schedule from Google Calendar

This feature integrates your scheduling directly into a tool you already use. You can schedule a WhatsApp reminder by just adding an internationally formatted phone number to the title or description of any Google Calendar event. When the event time arrives, WA Reminders automatically sends the message. It's perfect for those who already manage their appointments in Calendar, eliminating the need to switch between apps.

Schedule from the WA Reminders App

For more direct control, you can schedule messages from the WA Reminders app itself. A major benefit here is the automatic contact list import. The app pulls your full contact list from your phone, so you don't have to manually type in numbers. You can easily select a contact, type your message, set the date and time, and let the app handle the rest.

Recurring Message Scheduling

WA Reminders understands that many reminders happen on a regular basis. You can set up messages to repeat daily, weekly, monthly, or on a custom schedule. This is ideal for weekly class reminders, monthly payment follow-ups, or regular check-ins. You can set it once and forget it, ensuring your clients receive consistent communication without you lifting a finger each time.

Use Cases

Cosy

For Onboarding New Customers

If you use a Slack channel for customer support or success, Cosy ensures every new customer feels personally welcomed and guided from day one. Automate a sequence of DMs that introduces your team, shares key resources, and asks how you can help. This reduces the manual burden on your team while providing a consistent, high-touch onboarding experience that sets the tone for a great customer relationship.

For Building Internal Team Culture

Strengthen connections within your remote or hybrid company. Use Cosy's automated introductions to help employees from different departments meet each other regularly, fostering cross-collaboration and a stronger sense of belonging. The member directory also helps new hires learn about their colleagues' roles, skills, and interests, accelerating their integration into the team.

For Running a Paid Membership Community

Manage and grow your premium community efficiently. Cosy automates the initial welcome and orientation for new paying members, delivering immediate value. The member introductions feature encourages networking, which is a key benefit for members. Meanwhile, surfacing top content helps you identify and reward your most active members, keeping overall engagement high and churn low.

For Moderating Large Public Communities

Keep your large community safe and positive with less manual oversight. Use the content highlight tools to quickly identify highly engaged (or contentious) threads. While Cosy provides tools to flag spam, its automation of welcome and connection tasks frees up your time to focus on proactive community management, nuanced conflict resolution, and fostering healthy discussions instead of just administrative chores.

WA Reminders

Reducing No-Shows for Appointments

Clinics, salons, and consultants can dramatically reduce missed appointments. By scheduling a friendly reminder message for the day before or a few hours before an appointment, clients are much more likely to confirm, reschedule, or show up on time. This saves lost revenue and keeps daily schedules running smoothly for the business owner.

Automating Payment Follow-Ups

Freelancers, coaches, and small service providers can use WA Reminders to send polite payment reminders. When an invoice is due, a scheduled message can be sent directly to the client's WhatsApp, providing a convenient and personal nudge that often leads to faster payments, improving cash flow without awkward conversations.

Managing Class or Workshop Reminders

Fitness trainers, tutors, and workshop organizers can schedule recurring reminders for their weekly sessions. A message sent to all registered participants a day before the class improves attendance rates. This ensures everyone is prepared and informed, leading to better engagement and client satisfaction.

Streamlining Customer Follow-Ups

Small shops or service businesses can schedule follow-up messages after a purchase or service is completed. A simple "How was your experience?" or "Thank you for your purchase!" message sent a day later shows customers you care, helps gather feedback, and encourages repeat business, all through automated yet personal communication.

Frequently Asked Questions

Cosy FAQ

How do I install Cosy?

Installing Cosy is simple and takes just a few minutes. Just visit the Cosy website and click the "Install to Slack" button. You'll be guided through the standard Slack app authorization process, where you choose which workspace to add it to and grant the necessary permissions. Once installed, you can immediately start configuring your onboarding sequences and other features from the Cosy dashboard.

Is there a free plan?

Yes! Cosy offers a very generous free plan that supports communities with up to 250 members. This includes access to core features like automated onboarding, member introductions, the member directory, and content highlights. You can use the free plan indefinitely. For communities larger than 250 members, you can start a 30-day free trial of the unlimited members plan to test all features.

Can members opt-out of automated messages?

Absolutely. Member consent and comfort are important. For automated introductions, members must actively opt-in to participate. For onboarding messages and profile prompts, members can simply ignore the initial DM from Cosy. The tool is designed to be helpful, not intrusive, and gives you full control over how and when automated communications are sent.

Does Cosy work outside of Slack?

No, Cosy is built exclusively for Slack. It is a native Slack app, which means all its features—like sending DMs, reading public channel messages for highlights, and creating the directory—operate entirely within your Slack workspace. This ensures a seamless experience for both you and your community members without the need to switch between different platforms or log into a separate dashboard.

WA Reminders FAQ

How will my WhatsApp reminder messages look?

Your messages will appear to the recipient exactly as if you sent them manually from your own WhatsApp account. They will see your name, profile picture, and the message content you scheduled. The conversation will continue in your main WhatsApp chat thread, allowing you to reply naturally to any responses they send back.

Can I send reminders directly from Google Calendar?

Yes, absolutely! This is a key feature. You can schedule a WhatsApp message by simply creating an event in your Google Calendar and including a phone number (in international format, like +1234567890) in the event title or description. WA Reminders will detect this and send the reminder at the event's scheduled time.

Do you have a Calendly integration?

Yes, WA Reminders works with Calendly through Google Calendar integration. When you connect your Calendly to your Google Calendar, any appointment booked will create a calendar event. As long as the client's phone number is included in that event (which Calendly can be set up to do), WA Reminders will automatically send a WhatsApp reminder based on that event.

Can I import or use the contacts from my phone?

Yes. When you use the WA Reminders app to schedule a message, it automatically imports and syncs your phone's full contact list. This means you can easily select any contact to send a reminder to without having to manually enter their phone number, saving you time and preventing errors.
