AI agent is changing the way companies handle repetitive tasks. Unlike classic automation, an AI agent can process unstructured data and decide independently — without fixed rules.
What Is an AI Agent?
An AI agent is intelligent software that uses artificial intelligence to autonomously perform business tasks. Key capabilities of an AI agent:
- Understands context — analyzes meaning, not just keywords
- Decides independently — evaluates situations without human intervention
- Learns from data — improves performance based on experience
- Processes unstructured data — emails, PDFs, scanned documents
- Integrates with systems — connects ERP, CRM, databases
Classic Automation vs. AI Agent
| Aspect | Classic automation | AI agent |
|---|
| Rules | Fixed | Adaptive |
| Data | Structured | Any |
| Decision-making | Yes/No | Contextual |
| Example | "If an email contains 'invoice', move it" | "Identify the invoice, extract data, enter it into the system" |
How an AI Agent Works: 5 Phases
1. Perception — the AI agent collects data from emails, documents, databases
2. Processing — analyzes with AI models (GPT-4, Claude)
3. Decision — evaluates context and chooses the optimal step
4. Action — performs actions (data entry, sending email, updating systems)
5. Learning — improves based on results
Which Tasks Does an AI Agent Automate?
An AI agent works best for tasks that are:
- Repetitive — recur regularly
- Time-consuming — 30+ minutes per case
- Rule-based — clear criteria
- Data-heavy — hundreds of cases per month

How to Implement an AI Agent: 5 Steps
1. Identification (1-2 weeks)
Find tasks suitable for an AI agent:
- Do they recur regularly?
- Do they take hours of time?
- Are there clear rules?
2. ROI Analysis (1 day)
Calculate AI-agent ROI:
Current costs - Costs with an AI agent = Savings
Investment in an AI agent / Monthly savings = Payback
Example: An AI agent for invoices saves 35,000 Kč per month
3. AI Agent Pilot (2-3 months)
- Deploy the AI agent on 20-30% of the volume
- Measure the AI agent's performance
- Optimize weekly
4. AI Agent Evaluation
- Has the AI agent reached 60% automation?
- Is the AI agent's output quality OK?
- Are users satisfied with the AI agent?
5. Scaling the AI Agent
After success, expand the AI agent to other processes.
Most Common Mistakes When Deploying an AI Agent
Mistake 1: Expecting 100% automation from an AI agent
Reality: 80-90% is an excellent result for an AI agent
Mistake 2: Deploying an AI agent without measurement
Solution: Define KPIs before launching the AI agent
Mistake 3: Too much ambition at once
Solution: Start with one AI agent for one process
Mistake 4: Not informing employees about the AI agent
Solution: Involve people from the start of the AI agent implementation
Mistake 5: Poor data quality for the AI agent
Solution: Clean data before launching the AI agent
