What Are AI Agents? The Complete Guide
Explained simply: autonomous software that plans and executes tasks by itself, with tools, memory and reasoning. Architecture, use cases, examples.
Anyone asking what are AI agents usually gets an answer about chatbots. That is not quite right. A chatbot answers questions, an agent gets work done. An AI agent is not just a chat window that produces text. It plans, it uses tools, it remembers what was already done, and it explains its steps.
What makes an agent
Perception. It reads emails, calendars, files and web pages, depending on which tools it gets.
Planning. It breaks an order into steps and lines them up, without you having to specify each one.
Tools. It calls other programs, sends messages, books appointments, does arithmetic.
Memory. It knows what was discussed and decided over time.
Reasoning. It says why it takes a step, not just which one.
Use cases for small businesses
One agent drafts a job ad, posts it, answers first questions, arranges a call and puts it in the calendar. It does not do that alone, but with you. It takes the recurring steps, you keep the decision.
Another agent reads incoming messages, sorts them by urgency and summarises them, so you only look at what matters yourself.
What an agent is not
It is no black box that acts without you. It has limits you set. It gives no investment advice and makes no decisions a human must check.
Your data
Your account, your conversations and your files are stored on servers inside the European Union. The actual language processing partly runs at specialised providers outside the EU, depending on the mode. We do not keep quiet about that.
What it costs
All nine agents are included in every cloud plan. Cloud Starter is €25.99 per month, Cloud Professional €36.99 per month. Every item is listed openly in the shop.

The agents draft quotes, keep the calendar and sort the inbox, and nothing goes out before you approve it.
