What We Support

Professional Review of AI-Written Code & Consultation

A professional engineer reads the business tools and macros your employees built with generative AI and points out what is risky before you rely on them. PowerShell, VBA, C#, Python, and more. First month free, then 100k JPY per month (excl. tax).

A professional engineer reads and reviews the business tools, scripts, and macros your employees built with generative AI such as ChatGPT, Claude, or Copilot. We find what is risky before you rely on it in production and work out the fixes with you. The first month is free.

Does This Sound Familiar?

An employee built a tool with AI, but nobody can judge whether it is safe to use in production
It works, but nobody in the company can explain what is inside
If the person who built it moves or leaves, nobody will be able to fix it
It handles customer data or internal files, and you are not sure it is safe
Asking the AI again after every error has made the code more and more complicated
There is nobody in the company to ask how to instruct the AI

Generative AI now lets people who never learned to program build tools that work. But working is not the same as being safe to keep using. Code written by AI looks plausible, and the person who built it cannot tell when something is wrong.

Common Problems in AI-Written Code

Failures go unnoticed

The code swallows errors, so when a step fails nothing is shown and the work moves on with data missing.

It calls commands that do not exist

The AI wrote functions or settings that do not actually exist, so the tool fails only under certain conditions.

Passwords or API keys are written in the code

The moment the file is handed to someone, the credentials go with it.

No check before overwriting or deleting

If the target is specified wrongly, the original data is deleted or overwritten.

It stops on conditions nobody tried

Blank cells, full-width characters, date formats, large volumes — input that was not tried when the tool was built makes it stop or produce wrong results.

Japanese text gets garbled

Differences in Windows character encodings garble Japanese file names and file contents.

These problems are often in use without the builder noticing, which is why it pays to have a third party read the code before it goes into production.

About the Founder Who Does the Work

Go Komura, our founder, has worked as a software engineer on the development and troubleshooting of device control, communications, and long-running systems. We also use AI coding assistants in our own day-to-day development, and we see first-hand where AI goes plausibly wrong.

Reviews are not subcontracted. The founder does them directly.

What We Offer

Review of AI-Written Code

We read the tools, scripts, and macros your employees built with generative AI and explain, in plain language, what is risky and why before you rely on them in production.

Fix Consultation and AI-Ready Fix Instructions

We work out how to fix each finding with you and also hand it back as instructions you can pass straight to your AI. We re-check the fixed code as well.

Consultation Before Building or Rolling Out

Talk through what to have the AI build and how, and how to distribute and keep using the finished tool inside your company.

Languages We Cover

  • PowerShell
  • VBA (Excel and other macros)
  • C#
  • Python
  • Please ask about other languages too

Pricing

First month

Free

Send us your actual internal code and try the review and consultation free of charge. There is no fine-grained cap on the number of reviews during the free month.

From the second month

Monthly, excl. tax100kJPY

The standard fee is 100k JPY per month (excl. tax).

The service does not switch to paid automatically when the free month ends. Decide whether to continue after seeing what the first month delivered.

How It Works

1
Consultation and NDA We ask what tools you have, what they are for, and how you use them. We sign an NDA before receiving any code.
2
Review We read the code and explain what is risky and why. Fixes also come back as instructions you can pass straight to your AI.
3
Fix it together We re-check the fixed code and also help with the next tool you want to build.
4
First-month summary We give you a summary of the problems found and what has been done about them. Use it to decide whether to continue from the second month.

Frequently Asked Questions

Can we use this service if we do not know how to program?

Yes. The service is mainly for tools built with AI by employees who are not engineers. We explain findings with as little jargon as possible and also return the fixes in a form you can pass straight to your AI.

Which languages do you cover?

Languages commonly used on Windows, such as PowerShell, VBA (Excel and other macros), and C#, plus Python. Please ask about other languages too.

How much does it cost?

The first month is free. From the second month, the standard fee is 100k JPY per month (excl. tax). The service does not switch to paid automatically when the free month ends. Decide whether to continue after seeing what the first month delivered.

Is it safe to hand over our internal code and information?

We sign an NDA before receiving any code, including during the free month.

Can we use this service if we do not use GitHub or similar tools?

Yes. Just send us the files you built as they are.

If you review our code, can you guarantee it will have no bugs?

No. A review is advice that states which code and which points we checked. Anything we did not check, we tell you we did not check.
