Feature Comparison

Cosy

Automated Onboarding Sequences

Stop manually welcoming every new face! Cosy lets you create and automate up to 10 distinct onboarding welcome DM sequences, sent from you, a team member, or the Cosy bot itself. Fully customize messages with member names, links, and emojis, and schedule them to send immediately or on a delay (minutes, hours, or even months later). This ensures every member feels personally welcomed the moment they join, even while you sleep, saving you hours of repetitive administrative work and never dropping the ball on a first impression.

Automated Member Introductions

Foster genuine connections and break the ice on autopilot. Cosy automatically introduces opted-in community members to each other via DMs on a regular cadence you control (every 1-4 weeks). Introductions happen in a 3-person DM with the Cosy bot, and you can customize the intro message. It randomly matches members to enhance serendipity while avoiding recent matches, effortlessly growing engagement and helping your community members build their networks without any manual effort from you.

Slack-Native Member Directory

Build a living, searchable directory of your community without anyone ever leaving Slack. Create custom profile fields (text, single-select, or multi-choice) and notify all members to fill out their profiles with one click. New joiners get a prompt 24 hours after arriving. Members can then search for keywords and filter profiles directly within Slack using the Cosy app or a simple /member-directory slash command, making it easy for people to find the right help and connections.

Content Highlights & Moderation Alerts

Instantly surface the best of your community and stay on top of conversations. Use quick slash commands to find the top 10 most engaged posts in a specific channel (/most-engaged-messages) or across all public channels. You can also instantly flag abusive or spam messages for quick moderation action. This feature helps you celebrate great content, identify trending discussions, and maintain a healthy, positive community environment effortlessly.

Zovo

Privacy-First, Local-Only Processing

Every Zovo extension is engineered with an uncompromising privacy-first architecture. All processing happens directly on your device—your data, browsing history, clipboard content, and sessions never leave your computer. There are no backend servers, no cloud calls, and absolutely zero data collection or telemetry. This eliminates the risk of data breaches and ensures your digital activity remains truly yours, a stark contrast to the data-harvesting norm of most modern extensions.

Community-Driven Roadmap & Development

Zovo flips the traditional development model on its head. You are not just a user; you are the product manager. Users submit feature requests directly to the developer, who reads every single one. The community then votes on what gets built next, ensuring the most requested and valuable features are prioritized and shipped. This creates a powerful feedback loop where the tools evolve based on real user needs, not corporate guesswork.

Flagship AI Writing Tool: BeLikeNative

BeLikeNative is the standout tool in the suite, empowering over 3,300 users to communicate with confidence. It provides instant, one-keystroke rewriting and polishing of text directly in your browser across 80 languages. Whether you're crafting an email, posting on social media, or writing a document, it helps you sound fluent and natural, effectively bridging the gap for non-native speakers and anyone seeking more polished prose.

Comprehensive "Pro" Power Features

While all core extensions are free forever, the one-time Pro subscription unlocks a deep tier of advanced functionality across the entire suite. This includes powerful tools like Focus Mode for tab management, unlimited clipboard history with cross-device sync, session snapshots with auto-save on crash, advanced data export formats (CSV, YAML), custom themes, and priority direct support. One payment grants access to all current and future Pro features.

Frequently Asked Questions

Cosy FAQ

How does Cosy handle privacy and data?

Cosy is built with privacy as a core principle. It only accesses and uses data from public Slack channels and information from members who have opted into features like the directory or introductions. All data is handled securely, and Cosy complies with major data protection regulations. You maintain full control over what data is collected in your member directory.

Can I customize the automated messages?

Absolutely! Every automated message, from onboarding welcomes to member introductions, is fully customizable. You can insert member names, use emojis, include links to important resources, and set specific time delays for when messages are sent, allowing you to maintain your community's unique voice and tone.

What happens if a member replies to an automated DM?

If the onboarding DM is sent from you or a team member's account, the recipient can reply just like a normal DM, and the reply goes to that person's Slack inbox. If the message is sent from the Cosy bot, the bot does not currently respond to replies, keeping interactions clean and intentional.

Is there a free plan or trial?

Yes! Cosy offers a generous free plan for communities with up to 250 members. For larger communities, there is a full 30-day free trial for the unlimited members plan, allowing you to test all premium features thoroughly before making any commitment.

Zovo FAQ

Yes, absolutely. Privacy is Zovo's foundational principle. Every extension is designed to run entirely locally on your device. Your data—whether it's your browsing tabs, clipboard history, written text, or cookies—never leaves your computer. There are no analytics, no telemetry, and no servers sending your information elsewhere. You can verify this as many extensions are open source.

How does the pricing work?

Zovo operates on a transparent "free forever, Pro when you're ready" model. All 16+ core extensions and their basic features are completely free to install and use indefinitely, with no account required. A single, one-time payment of $99 unlocks the "Pro" tier across the entire suite, granting access to advanced power features like cross-device sync, unlimited history, session snapshots, and all future extensions.

How do I suggest a new feature or extension?

You have a direct line to the developer. Feature requests are actively encouraged and are the primary driver of Zovo's roadmap. You can submit your ideas through community channels, and all members get to vote on which suggestions are built next. The most popular requests are prioritized, making Zovo a truly user-shaped product.

What happens if I need help or have a problem?

You get to talk to a human—the developer himself. Zovo promises no bots and no ticket queues. Support is provided via direct email or through the active Discord community. This ensures personalized, prompt, and effective help for any issues or questions you may encounter.
