About

Imagine having a single, unified command center where your entire development and design workflow comes together seamlessly, powered by the latest in artificial intelligence. That's exactly what 9. Projekt offers: an unparalleled workspace built specifically for modern builders who are leveraging the power of AI agents. Forget juggling multiple windows, clunky interfaces, or being locked into proprietary systems. This tool is designed around your efficiency, allowing you to run several specialized AI coding agents concurrently. Picture this: you can have one agent handling front-end styling while another focuses on complex backend logic, all visible within a live preview that updates instantly as changes are made. This side-by-side execution environment drastically cuts down on context switching, letting you see the immediate impact of your agent's work, refine it with inline editing, and manage all associated files without ever leaving the main screen. It’s about creating a fluid, intuitive environment where human oversight meets machine speed, making complex development tasks feel surprisingly straightforward and fast.

What truly sets 9. Projekt apart is the commitment to keeping you in control of your resources and your destiny. We understand that relying on third-party APIs can be costly and restrictive, which is why we built this platform around a Bring Your Own Key, or BYOK, philosophy. This means you connect your own API keys for the underlying large language models, ensuring you only pay for what you use directly, eliminating vendor lock-in and unexpected subscription hikes. This flexibility is crucial for professionals who need predictable costs and the freedom to switch models based on project needs. It transforms 9. Projekt from just another tool into a strategic platform that respects your budget and technical autonomy. It’s the perfect synthesis of cutting-edge AI collaboration and essential developer freedom, wrapped up in a workspace that genuinely understands the rhythm of modern design and development.

Whether you are prototyping a complex application, iterating rapidly on user interface designs, or simply looking to accelerate your coding velocity, 9. Projekt provides the infrastructure to make it happen. It embraces the 'vibe coding' concept—that feeling when everything just clicks and progress flows effortlessly—by taking away the tedious administrative overhead. By centralizing agent management, live feedback, and file handling, this workspace empowers you to focus purely on creation. It’s not just about using AI; it’s about orchestrating a team of specialized digital assistants within one cohesive environment, giving you the ultimate advantage in delivering high-quality projects faster than ever before.
