AI agents - what are they and how do intelligent agents work?

Written by Persooa Team | Nov 14, 2025 8:28:51 AM

AI models have been used in business for years - from process automation to logistics to data analysis. Their evolution has meant that many companies can no longer imagine working without AI assistants, such as ChatGPT or customer service chatbots. Today, however, AI Agents are entering the scene - a new generation of autonomous systems that not only answer questions, but accomplish business goals on their own.

Find out how AI agents differ from assistants, what advantage they give you and where they can realistically support your business?

AI agent vs. intelligent assistant - they are not the same thing

To understand what all the fuss is about, you first need to understand the difference between commonly available assistants and personal AI agents.

  • An AI assistant is a reactive tool - it answers questions and executes single, clearly defined commands. Its role ends with generating a singular result.
  • An AI agent is a proactive system - it receives a goal from you and then takes steps on its own to achieve it.

 

How do AI agents work - what is it actually?

An AI agent is an autonomous system that functions like an additional employee of a company. It not only understands commands, but independently plans, predicts, determines the most effective actions, and then executes them. An AI agent is capable of performing multi-step tasks to achieve the overarching goal assigned to it.

An AI agent operates according to the scheme: Plan → Execute → Analyze → Adapt.

In order for it to work in this complex way, our agent must have its own "anatomy."

  1. Brain - usually a large LLM language model, responsible for planning and reasoning.
  2. Senses - the AI agent not only determines its path, but also explores it, checking its surroundings and context - it will not move to its destination in the dark. Internet access, integrations with databases / tools / applications, and reading files are responsible for this ability. The AI agent also has its memory: short-term - concerning the current task, long-term - the history of actions and the database.
  3. Hands - once the agent has the path taken, it's time to act. APIs and tools that the AI agent has access to are activated. These can be CRM systems, email inboxes and even other AI agents.

Revolutionizing business and e-commerce with your AI agents

AI agents can take over not only single tasks, but entire processes in a company. They operate 24/7 - ready to do their work in a target-optimized way. Where are AI agents already finding their uses in business?

AI agents in marketing

Marketing is all about speed and accuracy of decisions. An AI agent can analyze changes in your industry in real time, follow trends, watch the competition. A properly prepared AI agent executes the entire strategy: selecting key phrases, pre-creating briefs and recommending actions that increase conversions.

Unlike a classic assistant, an AI agent does not wait for you to ask it for analysis. It will actively look for opportunities itself - changes in the market and micro-trends, so that you can use them to your advantage.

 

Sell more effectively - even B2B - with an AI agent

In sales, especially in the B2B sector, it's not only quality that matters, but also personalization. AI agents can take the tasks of "cold mailing" and "lead nurturing" and take them to a more effective level. What might this look like in practice?

  • An AI agent searches company databases, social media (LinkedIn) or industry news, in search of potential customers.
  • It verifies the context, through which it determines whether the sales lead it finds is likely to be effective.
  • It provides a ready-made list for your salespeople, along with information about the lead and suggestions for action.

 

AI agents in logistics and e-commerce

AI agents can also become supply chain coordinators, operating at the interface of warehouse systems (WMS), ERP and courier platforms. They are specialists in historical data analysis, prediction and control of current product availability.

They can monitor shipment routes and identify possible optimizations, anticipate seasonal changes and adjust the warehouse to them - all this on an ongoing basis, 24/7 and without the intervention of an additional employee.

Customer service in a modern way

Personalization using AI can also be taken to a whole new level by using AI agents. They can analyze requests for returns and complaints, pull out the most important information, and automatically update systems - without unnecessary employee involvement.

If an order gets stuck or an error occurs, the AI agent can detect such problems on its own, inform the customer of the status of the order, and trigger the appropriate procedures within the company to resolve the complications.

What are AI agents for companies - artificial intelligence, and the future of business

With the development of AI agents, the way purchasing decisions are made is also changing. Increasingly, customers are using AI tools to automatically compare offers, analyze specifications, reviews and prices. This is the time to optimize and clean up your company website - stores that don't take care of product structural data, consistent descriptions, API access and optimization for machine readability may simply become invisible to customers.

This is a threat, but also a huge opportunity - a company that is ready for this change will gain an advantage that will soon be very difficult to catch up with.

AI agents are a great opportunity for your business. They are an additional employee who will relieve the workload of your team - reducing operational costs and increasing efficiency of operations. An AI agent can be a data analyst, a marketer, a logistics specialist - working without time constraints, performing tasks at a level that was unattainable just a few years ago.

If you want your business to operate faster, more efficiently and more predictably, now is the best time to hire your first AI agent.
