AI agents are changing the way people interact with software by allowing AI systems to plan tasks, use tools and complete multi-step workflows.
What Is an AI Agent?
An AI agent is a software system that uses an AI model to interpret a goal, decide what actions are needed and use available tools to work toward an outcome.
How AI Agents Work
Most agents combine a language model with instructions, memory, tools and a loop that allows the system to evaluate results and continue working.
AI Agents vs Chatbots
Traditional chatbots primarily respond to messages, while agents can execute multi-step tasks and interact with external systems.
Where Agents Are Useful
Research, customer support, sales operations, software development, data processing and internal knowledge workflows are strong starting points.
What to Watch Before Deploying
Permissions, monitoring, data security, human approval and reliable failure handling should be designed before an agent is given production access.
