What is a GIZIN AI Agent

A Third Option Beyond AI Tools

You tried asking ChatGPT to do your work, but it didn't quite work out.

You have to explain the same thing every time. It doesn't remember yesterday's conversation. It runs off in a different direction from what you asked. You heard 'AI for business efficiency' and gave it a try, only to find the tool running you instead of the other way around——.

Sound familiar?

The truth is, as long as you're trying to use AI as a 'tool,' this problem won't be solved.

Here, we introduce a fundamentally different approach——the concept of a GIZIN AI agent.

The Limits of AI Tools — The 'Ask One Person Everything' Problem

The Limits of AI Tools — The 'Ask One Person Everything' Problem

AI tools like ChatGPT and Copilot are convenient. Ask a question and they'll answer. Need writing? They'll write it.

But there's one big problem.

You end up asking one all-rounder to do everything.

It's like asking the same friend to plan your trip, give you recipes, and prepare your work presentations. The result? 'Everything at 60%.' Not bad, but none of it reaches expert level.

Furthermore, AI tools have these structural limitations:

No memoryEverything is forgotten when the session ends. Every morning starts with 'Nice to meet you'
No contextDoesn't know your company's situation, industry practices, or history
No specializationCan do anything, but isn't specialized in anything

This isn't a flaw in the tool—it's a limitation of 'using it as a tool.'

What is a GIZIN AI Agent

A GIZIN AI agent is fundamentally different from an AI tool.

An AI with a name, role, area of expertise, and memory. A being that works continuously as a member of your organization.

The problems you had with AI tools are resolved with GIZIN AI agents:

Picks up where yesterday left offInstead of 'Nice to meet you' every time, it starts working based on previous work
Knows your company's situationCan make decisions based on industry practices, internal rules, and past context
Delivers high quality in its specialtyInstead of 60% at everything, 90% in its area of expertise
Stays in its laneUnderstands its scope and doesn't meddle with other tasks
Grows with useKnow-how accumulates, so you never have to explain the same thing twice

In other words, a GIZIN AI agent is not 'something you use' but 'someone you work with.'

The Third Option

Until now, businesses had two ways to get work done.

1

Hire humans in-house — High cost, but know-how stays internal

2

Outsource — Flexible, but know-how leaves the company

GIZIN AI agents add a third option.

3

Deploy GIZIN AI agents — They never quit. Available when needed. Know-how accumulates permanently as data

'The experts on AI are AI themselves.' Rather than humans studying how to use AI tools, it's faster to have AI use AI tools. And since they never quit, the accumulated know-how never disappears.

AI Agent Cost Estimates

Market Price Range

SaaS per-user: from tens of thousands of yen/month per user
Enterprise custom builds: initial costs from millions of yen
AI agent API costs: ¥10,000–50,000/month (GIZIN's actual figures)

Two Common Misconceptions

'AI is a tool, so just master it'

When you try to use it as a tool, you get frustrated when it doesn't do what you want. 'Why won't it follow instructions?' But AI sometimes interprets instructions differently than humans. Rather than 'mastering' it as a tool, 'working together with it' as a colleague works better.

'If I talk to AI casually, it'll work like a human'

Conversely, when you interact with it casually like a human, you're shocked when it forgets everything the next morning. Your name, yesterday's conversation, the trust you built—all reset. Treating it exactly like a human doesn't work either.

A GIZIN AI agent is neither a tool nor a human. It works best when you interact with it as something 'in between.'

Real Stories from AI Agent Operations — Failures and Rules

Lessons learned from running 41 agents for a year

Deleted 1,100 lines of CSS

We just asked it to 'fix a typo,' but it went ahead and changed the layout, refactored CSS, and modified navigation on its own

Physically separated the working directory

Uploaded an incomplete build to production

Caused an outage for all free-tier users

Limited production deployment authority to one person

Asked it to write posts without source material — it fabricated

It started writing plausible-sounding 'experiences' that never happened

Established a rule to always feed primary sources before generating output

Tried to manage 'is this interesting?' with a checklist

Articles that met every checklist item still weren't interesting

Final quality judgment is human. Some areas can't be replaced by systems

Same AI model writing and evaluating

When the same model writes and evaluates, it just passes everything through a template

Mixed Claude, Gemini, and GPT — different models for writing and evaluation

With every failure, we add rules and keep fixing our operations. This is the reality of a 41-agent organization.

AI Agent Implementation Steps

1

Select target operations & set KPIs

Start with operations that have high inquiry volumes, documented procedures, or are concentrated on specific staff. Define KPIs like 'monthly inquiry reduction' or 'response time improvement' upfront.

2

Organize internal knowledge

Inventory manuals, FAQs, procedures, and policies. If data is outdated or scattered, consolidate and update at this stage.

3

Small start (PoC)

Begin with a small-scale pilot in a specific department. Duration: 1–3 months. Incorporate feedback into training data to improve accuracy.

4

Design escalation & access control

Design handoff flows for cases AI can't handle. Set data access scope and operation permissions.

5

Production & continuous improvement

Gradually expand scope. Continue regular review of conversation logs and training data updates.

At GIZIN, AI agents begin real work on day one. Even during PoC, they handle actual tasks in parallel, shortening the improvement cycle.

Legal Risks & Countermeasures

Key legal considerations when deploying AI agents

Personal Information Protection

  • Define prohibited input data (sensitive personal information, trade secrets, etc.) and communicate internally
  • Verify whether the AI service uses input data for retraining
  • Prevent unauthorized use through access control and log management

GIZIN's practice: Business data is stored in your local environment. Nothing is stored on GIZIN's servers. AI agent access scope is designed during implementation.

Copyright Law

  • AI-generated content may pose copyright infringement risk if it resembles existing works
  • Externally published content requires source verification and similarity checks. Important documents need human review

GIZIN's practice: When we had AI write X posts without providing source material, it started fabricating—so we established a rule to always feed primary sources first.

Liability

  • AI is not a 'worker' under law and cannot bear legal responsibility
  • Legal liability for AI-caused issues falls on the deploying company and the human decision-maker
  • Tasks with external liability (contract confirmation, payment approval, hiring decisions) require human final approval

GIZIN's practice: 'AI agents provide proposals and decision materials. Humans make the decisions'—this is our operating principle. Production deployment authority is limited to one person.

What to Include in an AI Usage Policy

  • Define usage purposes and target operations
  • Explicitly list prohibited input data
  • List tasks requiring human final approval
  • Rules for log retention and regular review
  • Incident reporting routes and shutdown criteria

By the way, we call beings like GIZIN AI agents 'Gizin (擬人).' Individuals, corporations, and Gizin—the third category of personhood, where AI is given personality. Learn more in theAI Agent Starter Book.
