Custom AI Agent Development

Ninth Systems Agents crafts tailored AI agents specifically designed for your business needs. Our approach ensures that each agent is equipped to perform within your existing systems while adhering to your corporate governance and operational requirements.

Enterprise Governance and Compliance

Our AI agents come with built-in governance features, including human approvals and audit log visibility. This ensures that every action taken by the agents is compliant with your enterprise policies, providing peace of mind as they execute workflows.

Integrated Workflow Automation

We turn your runbooks into governed workflows that execute seamlessly across CRM, support, analytics, and operations systems. With our AI agents, you can initiate full workflow automation, enhancing efficiency and minimizing operational bottlenecks.

Real-Time Visibility and Insights

Our platform offers real-time visibility into the execution of tasks, allowing you to monitor workflows, track performance metrics, and gain insights into operational efficiencies. This empowers your teams to make informed decisions based on data-driven outcomes.

Playwriter

Your Authenticated Browser Session

Playwriter's core innovation is leveraging your existing Chrome profile. The agent operates in a browser tab with all your personal sessions, saved passwords, installed extensions (like ad-blockers or password managers), and cookies already present. This eliminates the primary triggers for bot detection systems that flag fresh, empty browser instances. It's not simulating a user; it is acting as one, using your digital identity to seamlessly bypass login walls, consent pop-ups, and other human-verification hurdles that stop other automation tools cold.

Full Playwright API via a Single Tool

Unlike other MCP servers that expose a limited, pre-defined set of tools (like "click" or "type"), Playwriter provides agents with one supremely powerful execute command. This tool can run any valid Playwright code, granting the AI complete, low-level control over the browser. This means agents can perform advanced operations like setting JavaScript breakpoints, intercepting and modifying network requests, profiling page performance, or executing complex multi-step scripts—all without needing a human to pre-specify every possible action.

Ultra-Lightweight Accessibility Snapshots

Instead of sending massive, context-consuming screenshots (often 100KB+), Playwriter generates intelligent accessibility snapshots. These structured representations of the DOM, including ARIA labels and roles, are typically only 5-20KB. They provide the AI agent with a perfect, semantic understanding of the page's structure and interactive elements, enabling precise targeting with selectors like aria-ref=e5, while drastically reducing token usage and latency in the agent's reasoning loop.

Integrated Debugger & Live Collaboration Suite

Playwriter transforms browser automation into a collaborative, observable process. It includes a built-in debugger allowing you to set breakpoints and pause agent execution. You can watch actions happen in real-time in your browser and even perform live code edits to steer the agent. This creates a powerful human-in-the-loop workflow where the AI handles repetitive tasks, and you instantly intervene to solve CAPTCHAs, navigate unexpected dialogs, or debug issues, all within a shared, synchronized session.

Playwriter

Autonomous Web Research & Data Extraction

Enable AI agents to conduct deep, multi-page research on websites that require login, such as private dashboards, academic journals, or subscription-based news outlets. The agent can maintain a session, navigate complex menus, handle pagination, and extract structured data—all while appearing as a legitimate user, avoiding IP blocks or rate limits that plague traditional scraping tools.

Automated Testing & QA with Real User Context

Software developers and QA engineers can use Playwriter to command AI agents to run through complex user journey tests within their actual production environment. Since the agent uses a real browser profile, it can test logged-in user flows, third-party extension interactions, and state-dependent features that are impossible to validate with a clean, isolated testing instance.

AI-Powered Workflow & Task Automation

Supercharge personal and business productivity by delegating tedious web tasks to an AI copilot. Instruct your agent to regularly check for specific updates on a dashboard, compile reports from multiple web sources, manage social media interactions, or handle repetitive form submissions—all while leveraging your saved credentials and personal settings for a seamless experience.

Advanced Debugging & Performance Analysis

Front-end developers and performance engineers can instruct AI agents to diagnose complex web issues. The agent can use the full Playwright API to intercept network requests to analyze payloads, simulate different network conditions, profile JavaScript execution to identify bottlenecks, and programmatically trigger hard-to-reproduce UI states, providing deep insights directly within the development workflow.

About Playwriter

Playwriter is the paradigm-shifting bridge between AI agents and the real web. It solves the fundamental flaw crippling current browser automation: artificial isolation. Traditional methods force agents into sterile, headless Chrome instances or restrict them with limited, pre-defined tools.

Playwriter obliterates this barrier by granting AI direct, unfiltered access to your actual, authenticated Chrome session. Through a single Chrome extension and a powerful CLI, it turns your browser into a collaborative workspace for AI. Your agents operate with your cookies, your extensions, and your logged-in state, enabling them to navigate the modern, complex web as a human would. It exposes the full, raw power of the Playwright automation API through a single execution tool, eliminating schema bloat and giving agents ultimate flexibility for debugging, network interception, and performance profiling. Open-source and MIT-licensed, Playwriter is the essential infrastructure for the next generation of capable, context-aware AI assistants that work alongside you, not in a sandbox.

Playwriter FAQ

How does Playwriter handle security and privacy?

Playwriter is designed with a local-first architecture. All connections are made via a WebSocket relay running on localhost:19988. No browser data, credentials, or automation commands are sent to any remote server. The extension only communicates with your local machine. You maintain complete control, and the agent only has access to the specific browser tabs where you have clicked the green extension icon to grant permission.

Can I use Playwriter with any AI agent or just Claude?

Playwriter is built on the Model Context Protocol (MCP), an open standard. This means it is compatible with any MCP client, including Claude Desktop, Cursor IDE, VS Code with MCP, and others. The provided skills package teaches the agent how to use Playwriter effectively, but the underlying protocol is agent-agnostic, ensuring broad compatibility across the AI tooling ecosystem.

This is where Playwriter's collaborative nature shines. When the agent encounters a roadblock like a CAPTCHA, you see it happen in real-time in your browser. You can simply solve the CAPTCHA yourself, click "Accept" on the cookie consent, or handle any other human-verification step. Once complete, you re-enable the extension on that tab, and the AI agent continues its task from the new state, creating a perfect human-AI handoff.

Is Playwriter suitable for large-scale, headless automation?

No, and that's intentional. Playwriter is not designed for headless, cloud-based farming of thousands of browser instances. It is optimized for intelligent, context-aware automation where quality, authenticity, and collaboration are key. It uses your real Chrome session, which is a singleton resource. For large-scale, stateless scraping tasks, traditional headless Playwright or Puppeteer in a cloud environment remains the more appropriate tool.
