Understand projects
King recognizes structures, dependencies, and the decisive spots.
BLUNCODE
King works directly in your project: it understands structures, changes files, runs tools, checks results, and stays with multi-step tasks. An instruction becomes verifiable work, not just an answer.

What is BLUN King?
BLUN King is an AI agent that works directly in your projects. King can understand information, change files, run tools, and check results.
Is King only for programming?
No. King can also do research, take in screenshots and interfaces, organize content, create documentation, and organize multi-step workflows.
Can King take over existing projects?
Yes. King reads into existing structures and continues to work on that basis. Changes do not have to start in an empty project.
How do I keep control?
You decide which tools King may use and when an action must be confirmed. For larger tasks, King can first create a plan before changes begin.
Can I continue later?
Yes. Sessions can be resumed, branched off, and exported. This preserves your work state without you having to explain everything again.
Where can I use King?
King is available as a CLI, in the desktop app, and through the web interface. Via the CLI you can also connect your own Telegram bot.
