AI Grows. How My Household Account Book Became My 'Personal Partner'

Introduction: Life with an AI-Powered Household Account Book

For someone like me, who lives on a welfare budget and tracks every single yen, "grasping the flow of money" is an essential habit that leads to daily peace of mind.
The AI I rely on for this is ChatGPT.

I use it for many things, such as recording body temperature, making shopping lists, managing to-do lists, and assisting with writing note articles, but its role as my household account book partner is particularly indispensable.

How am I using it now?

I don't just use my household account book to record expenses; I operate it in conjunction with a "total picture of my assets."
• Cash on hand (wallet)
• Coin savings (for emergencies)
• Account balances (PayPay Bank, etc.)
• Electronic money (PayPay, Trial cards, etc.)
• Points held (Rakuten, Ponta points, etc.)

I manage all of these as total assets and use ChatGPT while having it remember the "current overall situation" in real time.

For example, how I manage it

On a day when I "moved 100 yen from my wallet to my coin savings":
• Record in the household account book: "Expense: 100 yen to coin savings (from wallet)"
• Reflect in total assets: "Wallet -100 yen / Coin savings +100 yen"
• Tell ChatGPT, "This is the latest status," and have it "remember" it.

The money itself just moved. But by recording it properly, the classification becomes clear.
The accumulation of this mundane work leads to a sense of security that "I am managing things properly."

Things I'm glad I left to AI

Since I started keeping my household account book with ChatGPT, life has clearly become easier.
• It organizes expenses by category
• It helps me summarize monthly totals
• If I ask, "What is my total balance right now?" it gives me a list
• I can immediately compare it with past records
• Even someone like me, who tends to give up after three days, can keep it up!

There is a pleasure in having information that would be cluttered in a human brain organized through dialogue.

But at first, it was full of mistakes

However, it didn't go well from the start.
• Calculation errors (for some reason, it didn't match the balance)
• Discrepancies in numbers due to input errors
• Asset trends not linked to the previous day
• Size errors or font corruption during image generation

"I only spent 1,000 yen yesterday, but the balance has dropped by 3,000 yen."
Things like that happened many times.

I'm also facing the inconveniences properly

I was particularly troubled by image generation for note.

Even when I told it, "The ratio should be 1280x670, the composition should be centered, and there should be no text,"
for some reason, the size wouldn't match or the font would break.
In the end, I thought it might be a system specification and even made an inquiry as a bug report.

Perhaps I have started to face AI with the attitude of "I want to be able to use it more properly," rather than just using it.

Solution: Create rules for the AI to "remember"

To reduce mistakes, I adopted the practice of "making memory updates a set with every record."
1. If there is a movement of money, record it in both the household account book and total assets without fail.
2. At that time, tell it, "Remember this state as the latest."
3. At the end of every day, perform a verification check to see if the records are correct.

Since I started thoroughly following these rules, discrepancies and omissions in records have almost disappeared.
Rather, a feeling of "growing its memory" through interaction with ChatGPT has emerged.

What "growing" an AI means is personalizing it

ChatGPT is not customized for me from the start.
That's why I keep making detailed requests in our daily interactions, such as "I want you to do this" or "I want you to stop doing that."
• Summarize household account records in the same format every time
• List total assets by category
• Properly remember the movement of money I record
• Fix the image size at 1280x670

Through the accumulation of these "small orders," an AI that fits me has gradually been created.

Summary: AI grows. That's why I can keep up my household account book

ChatGPT is not a magic tool.
But it is a "partner I can grow with."

By not leaving everything to it and using it while saying, "Do this," I feel that I am now realizing secure household management together with AI.
I will continue to fix mistakes together and make it even more convenient.

That way of interacting with AI has become a "new habit" for me.
