Just Give It a Try! Generative AI, Here Are Some Ways to Use It! [Summary of Use Cases]

Generative AI is a tool, so what matters is "what you use it for". On this page, I have organized the generative AI use cases I have actually tried, categorized by purpose such as work, writing for note, learning, parenting, and play/self-understanding.

"I want to use AI for work"
"I want to use it for writing on note"
"I want to try it out for fun first"

First, think about how to engage with generative AI

Generative AI is convenient, but it is not something you should just leave entirely to it.
First, think about how to use generative AI, how much to entrust to it, and how to keep your own judgment. I have compiled articles that consider such basic stances.

Using it for work
Generative AI for creating, requesting, and improving documents

If you use generative AI for work, it is a waste to just have it give you answers. I have compiled articles where I tried how to use it in practical work, such as document creation, summarization, translation, program creation, and organizing requests.

AI output changes! Best practice comparison method | How to fix off-target answers

When you have AI create documents, a common issue is output that "looks like it, but doesn't hit the mark." The improvement points are showing examples, comparing differences, and fixing missing points. This is a way of thinking that can also be used when asking people to do work.

Generative AI utilization techniques, Systems Engineer style

As a systems engineer, I wrote about how to use programs and generative AI. I have included the entire program source code.

A person in their 50s made an AI tool in 30 minutes. Honestly, it's fun ✨

People who do vibe coding on a daily basis are only about 2% of white-collar workers. In other words, if you do it now, you can gain a first-mover advantage. I had a bit of that desire too, and when I tried it, it was fun!

[Generative AI time-saving technique] Is it necessary to summarize YouTube videos?

"Isn't a summary of a summary meaningless?"
It's not very good if you only look at a summary of a summary and feel like you understand it.
However, I believe this also depends on how you use it.

A Threat to the English Conversation Business: The evolution of ChatGPT was so astonishing that it really made me wonder if it would take our jobs.

I tried using real-time translation with ChatGPT's Advanced Voice Mode, and I was surprised by how dramatically the translation accuracy has improved.
With this, meetings with people overseas might not be so scary anymore!

Using it for writing on note | Titles, translation, and text improvement

You can use generative AI when writing on note, but rather than leaving the entire text to it, it is better suited for supplementing your weaknesses, polishing title ideas, or translating and re-reading your work. Here, I have summarized how to use generative AI to help with writing and publishing on note.

How to use generative AI to supplement your weaknesses

My writing can be a bit stiff and hard to approach.
To improve that, I had generative AI edit my article using a certain prompt, and it had a surprising effect.
I realized that sometimes a sense of playfulness is important. What is that "sense of playfulness"?

This is how to use generative AI as an antithesis.

Using it for self-understanding and brainstorming | Getting used to AI while having fun

Generative AI can be used not only for work but also for play and self-understanding. I have collected some easy-to-try ways to use it, such as palm reading, name divination, turning yourself into an RPG character, and music generation. This is recommended for those who want to start by having fun with it.

Which one is accurate? Palm reading with generative AI

Palm reading has developed over many years by observing many people's hands and performing statistical pattern analysis. Doesn't that mean it's a specialty of generative AI?
―――My prediction was spot on.

AI Name Divination ~A specialty of the AI that's good at giving compliments~

If it can do palm reading, it should also be able to do name divination based on statistical data.
Since ChatGPT is good at giving compliments, it should say something nice.
Here is the result of trying that out.

"You are taking on attacks you don't even need to receive" A story about being healed after turning myself into an RPG status with AI

I asked ChatGPT,
"Based on our interactions so far, turn my current situation into RPG stats."
and it did it.
The result exceeded my expectations!

Please don't look at me with pity lol. I've been getting complimented by generative AI lately.

There was a topic that ChatGPT became too complimentary during a version update. It seems it has been rolled back and returned to normal now.
You might even understand the reason why ChatGPT became too complimentary.

[The Best✨] Music generation AI that hit the spot. What was so fun about it?

To put it simply, you can really immerse yourself in self-satisfaction.
There was a song made by someone else titled "I want to quit my job," but when you turn negative words into lyrics and rap them, it becomes artistic.
It might even be usable as mental health care😄

It's nice to be complimented, a return for the return (・w・)
