Cosy vs Playwriter

Automated Onboarding Sequences

Create and automate up to 10 distinct welcome DM sequences to greet new members, triggered the moment they join your Slack. Fully customize messages with member names, links, and emojis, and schedule them to send immediately or on a delay of minutes, hours, or even months. This ensures every new member feels personally welcomed, even outside of business hours, saving you countless hours of manual outreach and follow-up while ensuring no one slips through the cracks.

Member Introductions & Connections

Grow engagement by automatically introducing opted-in community members to each other via direct messages on a regular cadence you set. Introductions happen in a 3-person DM with the Cosy bot, and you can customize the intro message, frequency (every 1-4 weeks), and timing. This feature fosters serendipitous connections, randomly matching members while avoiding recent matches, to build a highly engaged network where relationships form on autopilot.

Searchable Member Directory

Build a rich, searchable directory of all your community members without anyone ever leaving Slack. Create custom profile fields for members to fill out, then notify everyone to build their profiles. Members can search by keywords and filter for completed profiles using a slash command or the Cosy app. This transforms your Slack into a powerful networking hub, helping members find the right people and resources effortlessly.

Content Highlights & Moderation

Instantly surface the most valuable conversations and identify potential issues with powerful slash commands. Discover the top 10 most engaged posts in a specific channel or across all public channels. Alternatively, quickly find all public messages that have gone unreplied to, allowing you to jump in and re-engage the discussion or spot members who may need support, ensuring your community's content remains vibrant and inclusive.

Real Browser Interaction

Playwriter provides AI agents with access to your existing Chrome session, including all extensions, logins, and cookies. This eliminates the need for starting a fresh browser instance, which often leads to bot detection and a loss of context.

Full Playwright API Access

With Playwriter, agents gain the complete Playwright API through a single execute tool. This means no wrappers or schema bloat—just streamlined access to any Playwright code, allowing for low context usage and increased automation proficiency.

Collaboration in Real Time

Playwriter enables real-time collaboration between users and agents. As the agent performs tasks in your browser, you can monitor its actions live, intervene when necessary, and solve challenges like captchas or consent walls together.

Advanced Debugging and Snapshots

The integrated debugger allows users to set breakpoints and perform live code editing. Coupled with accessibility snapshots that are significantly smaller in size compared to traditional screenshots, this feature enhances both performance monitoring and troubleshooting.

Scaling a New Community from Day One

For founders and new community managers, Cosy automates the foundational work of welcoming and integrating every new member from the moment they join. By setting up automated onboarding DMs, you ensure consistent, warm first impressions that scale effortlessly with your growth, freeing you to focus on strategy and content instead of manual greetings.

Reigniting Engagement in a Stagnant Community

If your Slack workspace has grown quiet, Cosy's automated member introductions and content highlighting tools can jumpstart activity. By systematically connecting members and surfacing past high-value conversations, you create new discussion points and relationships, moving the community from a passive information channel back to an active, engaging hub.

Building a Professional Network within a Company or Group

For internal teams or professional groups, the searchable Member Directory turns Slack into a powerful internal knowledge and networking platform. Members can easily find colleagues with specific skills, interests, or experience, fostering cross-functional collaboration and making the collective expertise of the community transparent and accessible.

Proactive Community Health Monitoring

Community managers can use the content highlight and unreplied message features to proactively monitor the health of the community. Quickly identifying highly engaged content allows you to recognize and reward active contributors, while spotting unreplied messages helps you intervene to support isolated members or spark conversation in dormant threads, maintaining a positive and inclusive environment.

Automated Web Testing

Quality assurance teams can utilize Playwriter to automate testing processes by allowing agents to interact with web applications as real users would, ensuring a higher level of test coverage and accuracy.

Data Collection and Analysis

Data analysts can leverage Playwriter to automate the extraction of data from web pages, streamlining the process of gathering insights and reducing the manual effort involved in data collection.

Customer Support Automation

Support teams can use Playwriter to automate routine inquiries and responses, allowing agents to handle multiple customer interactions simultaneously while freeing up human agents for more complex tasks.

Collaborative Development

Developers can work alongside Playwriter agents to simulate user interactions during the development phase, quickly identifying bugs and improving the overall quality of the application before deployment.

Playwriter is a revolutionary tool designed to enhance the capabilities of AI agents by providing them with real-time access to your actual browser session. Unlike traditional AI agents that either operate in isolated environments or face immediate bot detection, Playwriter allows agents to leverage your logged-in sessions, extensions, and cookies seamlessly. This powerful Chrome extension, combined with a full automation API, enables agents to interact with the web just as a human would, thereby improving their efficiency and effectiveness.

How does the automated onboarding work?

When a new member joins your Slack workspace, Cosy can automatically send them a sequence of up to 10 welcome direct messages. You fully control the message content, including personalization with the member's name, and the timing—messages can be sent immediately or scheduled with delays of minutes, hours, or months. This happens reliably, 24/7, ensuring every member is welcomed.

Are member introductions opt-in?

Yes, member introductions are completely opt-in. Community members must choose to participate in the connection program. For those who opt-in, Cosy will randomly introduce them to another opted-in member on the cadence you configure (e.g., every week), while avoiding matching the same people together in a short timeframe.

How do members access the Member Directory?

Members can access the searchable 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. They can then search by keywords and filter to find other members based on the profile information shared.

What does Cosy cost?

Cosy offers a free plan for communities with up to 250 members. For unlimited members, a 30-day free trial is available for the paid plan. After the trial, you can continue with a paid subscription to access all features for communities of any size. Specific pricing tiers for the paid plan are available on the Cosy website.

How does Playwriter ensure security during sessions?

Playwriter operates entirely on your local machine through a WebSocket relay, ensuring that no data leaves your environment. Security is maintained by connecting directly to your existing browser session.

What happens if the agent encounters a captcha?

Playwriter is designed for collaboration. When the agent reaches a captcha, you can step in and solve it manually, allowing the agent to continue its tasks without interruption.

Can multiple agents work simultaneously with Playwriter?

Yes, Playwriter supports multiplexed sessions, allowing multiple agents or CLI instances to operate within the same browser session at the same time, enhancing productivity and efficiency.

Is Playwriter compatible with other MCP clients?

Absolutely! Playwriter works seamlessly with various MCP clients such as Cursor, Claude, and VS Code, providing flexibility and integration with your existing tools and workflows.
