KI-Agent

An AI Agent is an AI system that autonomously plans, executes, and iterates on tasks — unlike simple chatbots that only respond to individual questions. Agents use LLMs as their "brain," combined with tools (web search, code execution, API calls, file access) to autonomously work through multi-step workflows.

Modern agent architecture: a planning module breaks tasks into steps, an execution module performs actions via tool calls, a memory module stores context across steps, and a reflection module checks results and corrects as needed. Frameworks like LangChain, CrewAI, and AutoGen simplify building agents.

Practical examples: coding agents like Cursor and GitHub Copilot navigate codebases autonomously, research agents search the web and synthesize findings, and marketing agents automate campaign setup, content distribution, and reporting. Automation platforms like n8n and Make enable agent-like workflows without programming.

The trend clearly points to Agentic Marketing — AI systems that don't just recommend but act independently. By 2027, forecasts suggest 30% of marketing operations will be handled by AI Agents. Humans shift from executors to supervisors and strategy providers.
