What Is an AI Agent? How It Differs from Traditional AI
Definition
An AI agent is an AI system that autonomously executes tasks. While traditional chatbots simply "answer questions," AI agents actually perform work on your behalf.
How AI Agents Differ from Traditional AI
| Aspect | Traditional AI (Chatbot) | AI Agent |
|---|---|---|
| Role | Advisor (gives recommendations) | Executor (acts on your behalf) |
| Behavior | Responds to questions | Autonomously executes tasks |
| Learning | Fixed rules | Learns and adapts to context |
| Integration | Standalone | Connects to multiple tools and systems |
Why AI Agents, and Why Now?
2026 is being called the "Year of AI Agent Implementation."
- AI is evolving from a "tool" to a "colleague"
- By 2028, the value created by AI agents is projected to expand to 29% (Bain forecast)
- Deloitte describes this as the rise of a "silicon-based workforce"
AI's role is shifting from automating simple tasks to handling work that requires judgment.

How to Choose an AI Agent: 5 Key Criteria
1. Define Your Objective
The right agent depends on what problem you're trying to solve.
| Goal | Recommended Agent Type |
|---|---|
| Automate customer support | Customer support-specialized |
| Internal knowledge search | RAG-enabled |
| Sales and marketing | CRM-integrated |
| Development and coding | Developer-specialized |
| Export control and compliance | Industry-specific specialized |
2. Security Requirements
When handling sensitive information, verify the following:
- Data storage location: Domestic or overseas servers?
- Security certifications: ISO 27001, SOC 2, etc.
- Data usage: Is your data used for model training?
From an economic security perspective, services running on domestic servers are recommended.
3. Integration with Existing Systems
Confirm compatibility with your current tools:
- CRM (Salesforce, HubSpot, etc.)
- Communication (Slack, Microsoft Teams, etc.)
- Storage (Google Drive, SharePoint, etc.)
4. Pricing Model
AI agent pricing varies considerably:
| Model | Characteristics |
|---|---|
| Pay-per-use | Pay only for what you use |
| Monthly flat fee | Easier budget management |
| Per-seat pricing | Scales with number of users |
5. Support
Post-deployment support matters:
- Japanese language support availability
- Implementation assistance
- Customization capabilities
