What Is an AI Agent?

From 'Conversational AI' to 'Action-Oriented AI'... The Digital Revolution Led by AI Agents in 2026

Recent analysis of search keyword trends across major portals like Google and Naver reveals a rapid shift in the core focus of Artificial Intelligence (AI) technology: moving from simple 'Generative AI' to 'AI Agents.' Going beyond the previous standard of merely answering user queries, agent technology—capable of autonomously formulating plans and executing tasks—has emerged as a critical topic across industries.

What Are AI Agent Services and How Do They Differ from Previous AI?

According to analyses of Google's AI models (Gemini) and the latest technological trends, an AI Agent service is defined as a 'system that autonomously makes judgments and utilizes tools to achieve goals set by the user.'

The core differences distinguishing them from previous AI (simple chatbots or search-based AI) are as follows:

• Passivity vs. Proactivity: Previous AI was a passive tool that reacted only to specific user prompts (commands). In contrast, when given a goal, an AI Agent breaks it down into detailed steps, autonomously establishing a plan and executing it.
• Information Provision vs. Execution (Action): While existing AI was limited to summarizing information or generating text, AI Agents directly perform actual work—such as sending emails, booking travel, or writing and deploying code—through external API integration, software manipulation, and data analysis.
• Environmental Adaptability: AI Agents possess the flexibility to learn in real-time from feedback generated during task execution and to self-correct when errors occur to reach the final objective.

Key Trends in the AI Agent Market for 2026 The major trends in AI Agent technology and changes in the industry, confirmed through recent search data, can be summarized in the following list:

Completion of Autonomous Workflows: In enterprise solutions, AI Agents have begun handling complex project management beyond simple repetitive tasks.

• Proliferation of On-device AI Agents: The deployment of agents functioning as personal assistants while maintaining security based on internal data within personal smartphones or PCs is accelerating.
• Multimodal Integration: Agents capable of simultaneously understanding and processing not just text but also images, video, and voice have emerged, increasing efficiency in customer support and design workflows.
• Multi-agent Systems Collaboration: Instead of a single massive AI handling everything, a structure where multiple AI agents with specialized expertise communicate to solve complex problems is becoming the standard.

The Evolving Digital Ecosystem and Future Outlook On Naver blogs and news communities, discussions regarding the proliferation of AI Agents are active, ranging from positive evaluations that "the era of true personal assistants has arrived" to debates concerning "liability issues regarding the autonomous judgment of AI."

Specifically, Naver is strengthening user-customized shopping and reservation services through AI Agents linked to its search service, while Google is innovating work productivity by advancing agent functions integrated with Workspace. Experts predict that within the next 1 to 2 years, the ability to utilize AI Agents will become a key indicator determining the competitiveness of both individuals and enterprises.
