AI agents are clever virtual assistants that automate difficult decision-making processes. Unlike ordinary chatbots, they grasp context, learn from encounters, and carry out multi-step procedures. Businesses utilize them for customer service, IT helpdesks, and sales lead qualification. They link with CRM, ERP, and databases to obtain real-time data. In ticket resolutions, AI agents shorten response times from hours to seconds. NLP can handle voice and text questions in many languages. They automate back-office processes such as contract reviews and cost approvals. Machine learning gradually enhances their accuracy and autonomy. Companies that use AI Agents report efficiency benefits of 30-50% in operations.
