[Major Announcement] I'm holding a hands-on seminar on May 8th [Majin Agent]
Hello, this is Majin.
Recently, I created a "bomb" with Yamajin.
It's called "Majin Agent".
This is a pretty crazy system, so I've decided to hold a hands-on seminar that I've kept under wraps for a long time!
It's been half a year since the last seminar.
I only do these when the time is right.
I would love for all my followers to participate, so please let me introduce you to Majin Agent.
The current limitations of Gemini
First, take a look at this prompt.

I am sending such a complex request to Gemini all at once.
1. Analyze the video and create a manual with screenshots (HTML)
2. Convert it to PDF
3. Create a comprehension test from it using Google Forms
4. Put it all together and create a Gmail draft
For those of you who use Gemini regularly, you probably understand that...
there's no way it can do this.
When I actually sent it to Gemini, it shut down due to the overwhelming request.

Gemini: "Uh, that's impossible."
You can have Gemini create an HTML manual in Canvas, or write a Google Form outline or email text.
However, it is difficult toexecute this entire workflow in one go.
This is a feat that only a so-called "AI agent" can accomplish.
Sending the same request to Majin Agent
Now, I would like to introduce the "
Majin Agent" that Team Majin has developed independently.
I will send the same prompt as before to a dedicated Gem.
Then, this screen appeared on Canvas.

When I opened Gmail, the draft email was finished,

and inside it, thePDF manual with screenshotsand thelink to the comprehension test Google Formwere already embedded in the body.

All of this is completed withjust a single promptsent to the Gem called "
Majin Agent".
Can you feel how incredible this is...?
Writing from a photo to an existing spreadsheet
This isn't the only use case.
Next is this.
Take a photo of a business card with the Gemini app on your smartphone,
and request, "Record this in the spreadsheet."
Majin Agent wrote the contents of the business card into the specified spreadsheet for me.

It seems a bit plain, doesn't it? lol
But everyone, please remember.
Gemini can extract text from images.
It can alsocreate a newspreadsheet based on that.
However, could youwrite to an existing spreadsheet?
You actually can't do this.
By the way, it doesn't have to be a business card; you can apply the same method to anything you can take a photo of, such as receipts, forms, or pages of contracts.
For example, if you send a photo of a food nutrition label,
you can also create a nutrition management database.

Please try to imagine this in your own work.
Don't you have various ideas for how to use it?
Majin Agent makes possible the "final step" that is impossible with Gemini alone.
Not a specialized tool, but a foundation for controlling Google Workspace
There are many other use cases. This is just one example.

「紙の行事予定表からGoogleカレンダーに「新しいカレンダー」を作成し、すべての予定を登録する。」
@連携で自分のカレンダーに登録はできるけど
「カレンダーを追加」はできないよね。
Majin Agentならそこまでできる。

Majin Agent is not a tool specialized for a specific task, but a mechanism that
allows you to freely control Google Workspace.
Depending on your ideas, the ways to use it are infinitely expandable.
It's all contained within Google Workspace, so you can use it immediately
What on earth is the principle behind this...?
Some of you might have thought that.
Is it a newly announced Google feature?
Are they linking it with some external service?
Are they using a special API key?
None of the above.
It only uses standard Google Workspace features.
No additional tools or contracts required.
That is whyyou can reproduce it in your own workplace immediately.
This is a big deal.
No matter how smart an AI agent appears,
most of them are things you aren't allowed to use at work.
Even the popular ClaudeCode is only allowed in a handful of companies on corporate PCs.
But,Majin Agent only uses GWS.It doesn't even use the Gemini API.
That is why you can apply it to your work starting tomorrow.
This is Team Majin's greatest commitment, our philosophy.
However, I think few people can master a tool just by being handed it.
It is not a simple and clear mechanism like the "Majin Style".
(Of course, once you learn how to use it, even non-engineers can handle it)
I want you to actually work with me and take home one experience of "It works!".
Because that will become a real "skill" you can use in your practical work.
Therefore,we are holding a hands-on seminar for the first time in about half a year!
I will show you everything about this mysterious mechanism at the hands-on seminar.
We have decided to hold a hands-on seminar so that everyone can actually use "Majin Agent".
