Cosy vs Perkoon

Automated Onboarding Sequences

Eliminate the manual grind of welcoming every new member. Cosy allows you to create and automate up to 10 distinct welcome DM sequences, sent either from you, a team member, or the Cosy bot itself. 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 at 4:30 AM, saving you hours and guaranteeing no one is ever overlooked. If sent from a human profile, members can reply naturally, kickstarting genuine conversation from day one.

Automated Member Introductions

Foster deep connections and combat isolation by automatically introducing opted-in community members to each other via DM. Cosy handles the entire process, creating a 3-person DM with the two members and the Cosy bot on a regular cadence you control (every 1-4 weeks). It randomly selects members to enhance serendipity while avoiding recent matches. You can fully customize the intro message template, weekday, and time (UTC). This feature builds a highly engaged network on autopilot, driving the meaningful interactions that define a true community.

Slack-Native Member Directory

Build a searchable knowledge base of your members without anyone ever leaving Slack. Create a custom directory with up to 10 fields (text, single-select, or multi-choice) and prompt members to fill out their profiles via a one-click notification. Members can then search for keywords and filter profiles directly within the Cosy app or via a /member-directory slash command. New joiners are automatically prompted after 24 hours. This turns your Slack into a powerful, internal network where members can easily find and connect with the right people.

Content Highlights & Moderation Alerts

Surface the most valuable conversations and maintain community health instantly. Use simple slash commands to pull the top 10 most engaged posts in a specific channel (/most-engaged-messages) or across all public channels (/most-engaged-messages-all). Identify unanswered questions with /unreplied-messages to ensure nothing slips through the cracks. Furthermore, Cosy proactively flags abusive and spam messages in real-time, allowing moderators to act swiftly to maintain a positive and safe environment for all members.

Peer-to-Peer File Transfer

Perkoon’s flagship feature allows users to transfer files directly between browsers with no size limits and without creating accounts. This P2P method ensures that data privacy is maintained, as files do not pass through a central server, making file sharing seamless and secure.

Encrypted Cloud Storage

When sending files to offline recipients, Perkoon provides an encrypted cloud storage option. This feature is essential for securing your data while it is temporarily held until the recipient can access it, ensuring that privacy and security are never compromised.

Built-in Automation Tools

Designed for the modern user, Perkoon includes native automation tools that enable AI agents to interact with the service directly. This eliminates the need for screen-scraping and enhances the efficiency of file transfers, making it a powerful tool for tech-savvy users.

User-Friendly CLI Tool

Perkoon offers a simple command-line interface (CLI) tool that allows advanced users and developers to interact with the service effortlessly. This feature is perfect for those who prefer a more technical approach to file transfers, enhancing customization and control over the transfer process.

For Scaling Startup Communities

Startup founders and early community managers are stretched thin. Cosy is essential for automating the foundational engagement tasks that make a community feel alive as it grows from 50 to 500+ members. It ensures every new member gets a personalized welcome, helps them find relevant peers automatically, and allows them to explore a member directory—all without constant manual intervention, freeing up leadership to focus on strategy and high-touch interactions.

For Professional Network & Membership Groups

Professional networks require meaningful connections to deliver value. Cosy automates the serendipitous networking that members join for, via its automated 1:1 introductions. The searchable member directory becomes a vital resource for finding expertise, potential collaborators, or mentors within the community, directly within the Slack platform they already use daily, dramatically increasing the network's utility and stickiness.

For Internal Company Engagement & Culture

Team leaders and HR professionals can use Cosy to transform internal Slack workspaces into more connected company cultures. Automate onboarding for new hires with tailored sequences from their manager or team. Foster cross-departmental relationships with automated introductions to break down silos. The member directory helps employees discover colleagues' skills and interests, building a more cohesive and collaborative internal community.

For Moderating Large, Public Communities

Managing large, active public Slack communities is a constant challenge for moderation. Cosy is a necessity for maintaining safety and quality. Its instant alerting for abusive or spam messages allows moderators to act before issues escalate. Meanwhile, features like highlighting unreplied messages help community managers ensure questions get answers, and surfacing top content rewards valuable contributions, guiding community culture positively.

Everyday File Sharing

Perkoon is ideal for everyday users who need to send files quickly to friends or colleagues without the hassle of signing up for accounts. Whether it’s sharing vacation photos or work documents, Perkoon simplifies the process.

Large File Transfers

For professionals working with large files, such as designers or videographers, Perkoon’s P2P service allows for the transfer of hefty files without worries about size restrictions or costs, making it a reliable choice for creative industries.

Secure Business Communications

Businesses can utilize Perkoon for secure file transfers, ensuring that sensitive documents are sent privately and efficiently. The encrypted cloud storage feature provides an extra layer of security for important data.

Integration with AI Systems

Developers can leverage Perkoon’s built-in automation tools to integrate file transfer capabilities directly into their AI systems. This allows for streamlined workflows and enhances the productivity of AI-driven applications.

Perkoon is a revolutionary file transfer service designed to simplify your digital life by providing a straightforward way to move files from one point to another without unnecessary complications. It is tailored for individuals and businesses alike who are weary of cumbersome restrictions, obligatory sign-ups, and services that commoditize personal data. At the heart of Perkoon are two fundamental methods for file transfer: a free peer-to-peer (P2P) system that enables users to send files directly between browsers in real time, and a secure cloud storage option for offline transfers. The P2P feature ensures that there are no size limitations and no need for accounts, making it a hassle-free experience. Your data remains private, as it never touches a central server, allowing Perkoon to operate at no cost to users. For offline recipients, the paid cloud storage service provides necessary encryption to keep your files secure. Perkoon is uniquely positioned for the AI age, featuring built-in automation tools and a simple command-line interface, making it an ideal solution for both everyday users and AI systems.

How does the automated onboarding work?

You can create up to 10 distinct welcome message sequences in Cosy. When a new member joins your Slack, Cosy automatically sends these DMs based on your configuration. You choose the sender (you, a teammate, or the Cosy bot), fully customize the message content, and set precise time delays (e.g., send immediately, after 24 hours, or a week later). This happens automatically, 24/7, ensuring consistent onboarding for every single member without any manual effort from your team.

How are members matched for introductions?

Opted-in community members are randomly selected and introduced to each other in a 3-person DM that includes the Cosy bot. The matching is designed for serendipity, similar to tools like Donut. Cosy's algorithm avoids matching people who have been recently introduced to each other 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.

Can members access the directory without leaving Slack?

Absolutely. This is a core benefit of Cosy's Slack-native design. Members can access the full, searchable member directory in two ways: by opening the Cosy app within Slack, or by using the /member-directory slash command in any public channel, which provides a quick link. All searching and filtering of profiles happens directly within the Slack interface—no external websites or logins are required.

What does Cosy do with flagged spam or abusive messages?

Cosy proactively monitors conversations and uses systems to instantly flag messages it identifies as potentially abusive or spam. These alerts are sent to community moderators or admins within Cosy, allowing for swift review and action, such as deleting the message or addressing the member. This helps maintain a safe and positive community environment by catching issues early, often before they are widely seen or cause harm.

Why is Perkoon free?

Perkoon operates its P2P transfer service free of charge because it incurs minimal costs. The cloud storage option, which is a paid feature, covers the necessary expenses for server maintenance, ensuring users can enjoy free transfers without hidden fees.

Can I transfer files if the recipient is offline?

Yes, Perkoon holds files for offline recipients using its encrypted cloud storage service. This allows users to send files even when the recipient is not currently available, ensuring that file transfers are convenient and flexible.

What browsers are compatible with Perkoon?

Perkoon works seamlessly with Chrome, Edge, and Brave browsers, which support unlimited file transfers. However, users of Firefox and Safari may experience certain restrictions due to browser limitations, so using a compatible browser is recommended for the best experience.

How does Perkoon ensure my privacy?

Perkoon prioritizes user privacy by employing a P2P model where files do not pass through central servers. In addition, the cloud storage service encrypts files, ensuring that even the company cannot see the contents of your transfers. Your data remains yours at all times.
