Feature Comparison
Cosy
Automated Onboarding Sequences
Cosy eliminates the manual burden of welcoming new members by allowing you to create and automate up to 10 distinct welcome DM sequences. These can be triggered immediately or on a custom delay when a new member joins. You can fully customize messages with the member's name, links, and emojis, and choose to send them from yourself, a team member, or the Cosy bot. This ensures every new member receives a warm, timely welcome, even outside of business hours, saving you hours of effort and preventing anyone from slipping through the cracks.
Member Introductions & Connections
To combat the isolation that can occur in large communities, Cosy automatically introduces opted-in members to each other via direct message on a regular cadence you set (e.g., every 1-4 weeks). Introductions happen in a 3-person DM with the two members and the Cosy bot, fostering serendipitous connections. The system intelligently avoids recent matches, ensuring members meet new people each time. This feature automates relationship-building, driving deeper engagement and helping members build their network effortlessly.
Searchable Member Directory
Cosy solves the problem of members not knowing who's in their community or how to find help. It creates a simple, searchable directory entirely within Slack. You can customize up to 10 profile fields (text, single-select, multi-select) and prompt members to fill them out via automated notifications. Members can then search for keywords or filter profiles using the /member-directory slash command, making it easy to find the right people without ever leaving the Slack workspace.
Content Highlights & Moderation
Surfacing valuable conversations and identifying issues is a key community challenge. Cosy provides instant insights with simple slash commands. Use /most-engaged-messages to highlight the top posts in a channel, or /most-engaged-messages-all for top content across all public channels. The /unreplied-messages command helps you find posts that need attention. Additionally, Cosy allows community managers to instantly flag abusive or spam messages, helping maintain a positive and safe environment for all members.
WA Reminders
Seamless WhatsApp Integration
WA Reminders works by linking to your WhatsApp account—either Business or personal—via a secure QR code scan, similar to WhatsApp Web. This foundational feature ensures all scheduled messages are sent directly from your own verified phone number. Your clients receive reminders in a familiar, trusted chat thread, allowing for a natural continuation of the conversation. You maintain full control and context of all communications within your primary WhatsApp interface, eliminating the need to manage a separate, impersonal broadcast system.
Dual Scheduling Methods: App & Google Calendar
This feature offers unparalleled flexibility in how you manage reminders. You can schedule messages directly within the intuitive WA Reminders app, which automatically imports your full phone contact list for easy selection. Alternatively, for those who live by their calendar, you can schedule by simply adding an internationally formatted phone number to any Google Calendar event title or description. This dual approach adapts to your workflow, whether you prefer a dedicated tool or a hands-off, calendar-centric automation.
Automatic Contact List Sync
Eliminate the tedious and error-prone process of manually entering client phone numbers. When scheduling from the WA Reminders app, your device's full contact list is automatically imported and synced. This saves significant administrative time and prevents missed reminders due to typos or outdated numbers. It ensures your entire client database is readily available, making the scheduling process quick, efficient, and comprehensive.
Support for Recurring Events & Reminders
For businesses with repeating appointments, classes, or subscription services, this feature is a game-changer. WA Reminders allows you to set up recurring message schedules directly from the app. When integrated with Google Calendar, recurring calendar events automatically generate corresponding WhatsApp reminders. This "set it and forget it" functionality ensures consistent, reliable communication for ongoing client engagements without requiring manual intervention for each instance.
Use Cases
Cosy
Scaling Community Onboarding
For growing communities, personally welcoming dozens or hundreds of new members each week is impossible. Cosy automates this entire process with personalized, multi-step welcome sequences. New members feel immediately valued with timely messages that guide them, share important resources, and set the tone for engagement, all while freeing the community manager to focus on higher-level strategy and interaction.
Fostering Peer-to-Peer Networking
In large Slack groups, members often struggle to break out of their cliques or find relevant connections. Cosy's automated introduction system proactively connects members with shared interests or complementary skills on a regular schedule. This transforms a passive member list into an active network, increasing collaboration, knowledge sharing, and overall member satisfaction through facilitated, serendipitous meetings.
Building an Accessible Knowledge Hub
Communities lose valuable insights when great questions and answers get buried in busy channels. Cosy's content highlight features allow managers to instantly surface the most engaged-with posts and identify unanswered questions. This turns the community's own conversation history into a searchable knowledge base, rewarding contributors and ensuring helpful information doesn't go to waste.
Maintaining Community Health & Safety
Managing disruptive behavior manually is reactive and stressful. Cosy empowers community managers by providing tools to instantly flag spam or abusive messages for review. Combined with the ability to monitor engagement and unreplied posts, managers can proactively nurture positive discussions and quickly address issues, maintaining a respectful and valuable environment for all members.
WA Reminders
Reducing Patient No-Shows for Medical Clinics
Physiotherapy clinics, dental practices, and therapy centers face significant revenue loss from missed appointments. WA Reminders solves this by automating appointment confirmations and reminders 24-48 hours in advance. Staff can manage everything from Google Calendar, sending gentle nudges directly to the patient's WhatsApp. This reduces administrative burden, decreases no-shows, and optimizes the practitioner's valuable schedule, leading to a more efficient and profitable practice.
Streamlining Appointment Management for Solo Professionals
Independent consultants, personal trainers, and beauty therapists often juggle client communication single-handedly. Manually texting reminders eats into their billable hours. WA Reminders automates this process, allowing them to schedule all reminders for the week in one sitting. Clients receive professional, timely messages, improving punctuality and satisfaction. The professional gets to focus on delivering their service rather than administrative follow-up.
Improving Payment Reminders for Small Businesses
Small shops, freelancers, and service providers frequently struggle with late payments. WA Reminders can be used to schedule polite payment follow-ups or invoice notifications via WhatsApp. By automating these sensitive reminders, businesses ensure consistent communication without the awkwardness of manual chasing. This leads to improved cash flow and maintains positive client relationships through professional, automated touchpoints.
Coordinating Team Schedules for Service Centers
For businesses like repair centers or tutoring services with multiple staff, coordinating client reminders can be chaotic. Using the Google Calendar integration, each team member's schedule can feed into a centralized reminder system. Managers or administrators can oversee all outgoing communications, ensuring every client receives a uniform reminder from the company's main WhatsApp number, improving brand consistency and operational coordination.

It seamlessly integrates with the world's most popular messaging platform, allowing clinics, independent professionals, and small shops to schedule messages for later delivery. You can schedule directly within the WA Reminders app or, for ultimate convenience, sync with Google Calendar to trigger reminders from your existing events. This ensures clients receive timely, personal reminders on the channel they use daily, dramatically reducing no-show rates. The value proposition is clear: reclaim lost hours, increase operational efficiency, and improve client reliability—all by automating a fundamental but time-consuming business task.
Frequently Asked Questions
Cosy FAQ
How does the automated onboarding work?
When a new member joins your Slack workspace, Cosy can automatically send them a sequence of welcome direct messages. You create and customize up to 10 messages, deciding the content, sender (you, a teammate, or the Cosy bot), and the timing delay between each message (from immediately to months in the future). This happens 24/7, ensuring every member is welcomed consistently, even if they join in the middle of the night.
How are members matched for introductions?
Opted-in members are randomly selected to be introduced to each other, similar to tools like Donut, to enhance serendipity. Cosy's algorithm avoids matching people who have been recently introduced to ensure fresh connections. You control the frequency (every 1, 2, 3, or 4 weeks) and the specific day and time (in UTC) when these introductions are sent out via a 3-person DM.
Can members opt-out of the introductions?
Yes. Community members have full control and can opt-out of receiving automated introductions at any time. The system only matches members who have chosen to participate, ensuring the connections are welcome and desired, which leads to more meaningful interactions and higher engagement rates.
Is there a free plan available?
Yes, Cosy offers a free plan that supports communities with up to 250 members. This allows you to experience the core automation features. For communities needing to support unlimited members, a 30-day free trial of the paid plan is available, after which you can choose to subscribe based on your community's size and needs.
WA Reminders FAQ
How will my WhatsApp reminder messages look?
Your reminders will appear in your client's WhatsApp chat list exactly as a standard message from you. They are sent from your linked phone number, so the client sees your name/profile picture. The message content is what you schedule—it could be a simple appointment time reminder, a confirmation request, or a personalized note. The client can then reply directly to that message thread, and the conversation will continue in your main WhatsApp inbox as normal.
Can I send reminders directly from Google Calendar?
Yes, absolutely. This is a core feature of WA Reminders. Once integrated, you can schedule a WhatsApp reminder by simply adding an internationally formatted phone number (e.g., +1234567890) to the title or description of any Google Calendar event. The system will detect the number and automatically send a reminder at the time of the event. This is perfect for users who already manage their appointments within Google Calendar.
Do you have a Calendly integration?
WA Reminders integrates with Calendly through Google Calendar. When a client books an appointment via your Calendly link, the event (with the client's details) is automatically added to your connected Google Calendar. WA Reminders will then read that calendar event and send the WhatsApp reminder based on the event time and the phone number pulled from the booking, creating a fully automated workflow from booking to reminder.
Which countries do you support sending messages from?
WA Reminders is designed to work with WhatsApp globally. As long as you have a valid WhatsApp account and phone number, you can use the service to send reminders. The app itself is accessible worldwide. The key requirement is that your recipient's phone number must be in an internationally formatted style (with country code) for the scheduling to work correctly, regardless of their location.
