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.

Zovo

BeLikeNative

BeLikeNative is an innovative writing tool that helps users express themselves like native speakers. With one keystroke, it instantly rewrites text in 80 different languages, making it perfect for non-native speakers who want to improve their writing skills. This extension is designed to work seamlessly across various platforms, ensuring that your writing is polished and professional, no matter where you are.

Tab Suspender Pro

Tab Suspender Pro is a powerful extension aimed at saving memory by automatically suspending inactive tabs. By detecting which tabs are not in use, it reduces your browser's memory consumption, leading to a smoother and faster browsing experience. This feature is particularly beneficial for users who tend to keep many tabs open at once, as it helps maintain optimal performance without manual intervention.

JSON Formatter Pro

JSON Formatter Pro is essential for anyone working with JSON data. This tool formats, validates, and explores JSON files locally, providing a beautification option as well as minification. Users can also utilize a tree explorer feature to navigate complex JSON structures more easily. It supports YAML and CSV conversions, making it versatile for various data handling tasks.

Clipboard History Pro

Clipboard History Pro ensures that users never lose important copied text again. With the ability to store up to 10,000 clips, this extension allows for instant searching and smart pasting of previously copied content. This feature is ideal for users who frequently copy and paste information, providing them with a reliable history of their clipboard activity.

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.

Zovo

Enhancing Writing Skills

BeLikeNative is perfect for students, professionals, and anyone looking to refine their writing. Whether drafting emails, essays, or reports, users can rely on its real-time rewriting capabilities to achieve a native-like fluency in their writing, making communication clearer and more effective.

Managing Browser Memory

For users who work with numerous tabs, Tab Suspender Pro is a game-changer. It allows seamless management of browser memory, automatically suspending tabs that are not currently needed. This enhances overall browser performance, making multitasking more efficient without the frustration of sluggishness.

Working with JSON Data

Developers and data analysts will find JSON Formatter Pro indispensable. It simplifies the process of handling JSON files, allowing for quick formatting and validation. The tree explorer view makes it easier to understand complex data structures, streamlining workflow and facilitating better data manipulation.

Organizing Clipboard Data

Clipboard History Pro is particularly useful for writers, researchers, and anyone who frequently copies text. By keeping a detailed history of clipboard items, users can quickly retrieve and utilize past content without the fear of losing important information. This increases productivity and reduces time spent searching for previously copied text.
