“Externalize” your design sense. Announcement of a major update to Meta-Prompt v3 (with Design Unit support). #217

This time it's the v3 update announcement for #129.
……But, since it would be a shame to just end it as a simple advertisement,

• What exactly is #129 anyway? (A recap)

• What can you do now in v3? (Additional features)

I'll write a proper summary of these points.

“Setting aside whether you buy it or not,”
the way of thinking alone might be helpful, so please read it when you have some free time.

Alright, here we go.

1. What is #129, really? (It's not a template)

There are tons of “templates to make a thumbnail in 5 minutes” floating around the world.
But what I'm making with #129 isn't that kind of “container”.

What I'm selling is not a container (template), but an engine (logic).

What makes it an engine?

Getting AI to “draw a pretty picture” is already standard.
But the hardest part is actually what comes before that.

Thinking about this from scratch every time is the most exhausting part.

That's why #129 is designed to have the AI read the context of the text and design the composition, protagonist, and atmosphere first.

It's not about “searching for spells,” but
“designing first, then casting” is the feeling.

2. The highlight of v3: Design Unit (Made it possible to externalize the look)

This is the biggest change I've included in this v3.

I separated the “content” from the “look” (design)

Up until now, you've always done it like this, right?

• Searching for a nice art style

• Adding fancy-sounding words

• Thinking 'this isn't quite right...' and redoing it

• Giving up and saying 'forget it...'

v3 has put an end to that.

The content (article summary) remains as is, and we've adopted a method where
the look (Design Unit) is simply snapped on at the end.

In programming terms, this is like separating HTML and CSS.
You can change the look without altering the content.

3. What is a Design Unit? (In a nutshell, a 'design standard')

Broadly speaking, a Design Unit is a block that summarizes 'visual rules' such as:

• background color

• text color

• tone (worldview)

• motifs

• typography vibe

like these.

And the rule for v3 is clear:

If a Design Unit and STYLE_MODE conflict, the Design Unit takes priority. (In other words, it's hard to break the 'consistency of the worldview'.)

4. How to use it: Just 'select and paste' (3 steps)

This is the important part.
What you do is really simple.

Step 1 | Drop in the SOURCE_TEXT (90% of the work)

First, put the article summary into SOURCE_TEXT.
It's more stable with shorter text than long passages.

Step 2 | Standard input (the bare minimum)

• STYLE_MODE: Base drawing mode

• PLATFORM_PROFILE: Usage (e.g., for note thumbnails)

• CANVAS: Aspect ratio (16:9 is reliable for note)

• TEXT_IN_IMAGE: Include text? (false recommended for beginners)

* You can just follow the template for this part. If you're unsure, just run it with the minimum configuration.

Step 3 | “Paste” the Design Unit at the end (follow this rule only)

This is the core of v3.

For the Design Unit, just copy the block starting with “Overall design settings:” and paste it as-is at the very bottom of your message.

The prompt also says, “Just copy the Design Unit from HP and paste it at the very bottom of your message.”

In other words,

5. What are the benefits? (What you can do with v3)

To put it very simply, here is what you can now do with v3.

✅ You can “unify” the world view of your thumbnails

Once you decide on one Design Unit, past and future articles will have the same tone.
This makes your articles start to look like assets.

✅ Design hesitation disappears

The time spent worrying about “What color should I use...” or “What art style should I use...” is reduced.
You only need to decide on the “content”.

✅ You can mass-produce (this is the main point)

Thumbnail production becomes operations rather than “creative work.”
This is the strongest part.

6. Who is this for? (People who will find it useful / People who won't)

For those who have read this far and are wondering, "Do I really need this?", I will be honest.

✅ People who will find this useful

• People who want their thumbnails to look different from others

• People who find searching for thumbnails to be a hassle

• People who are interested in trying their hand at making thumbnails

• People who want to be particular about design but want to spend less time tweaking prompts

• People with a logical, scientific mindset who want to control AI with logic rather than spells

❌ People who won't find this useful

• People who are satisfied as long as they get a decent-looking image
  → Free templates are fine. That's probably the right answer for you.

• People who are already satisfied with their thumbnails

7. Revision History (When was v3 added?)

As for the revision history,

• 2026/01/05: Paid version released, v2 added

• 2026/01/12: Generated images & usage instructions added

• 2026/01/14: Design Unit support (v3) added

That's how it's been going.

To those who purchased it previously,
I added the feature descriptions, but sorry for not announcing it...
I think v3 is pretty good, so please give it a try lol

8. About the price

Oh, by the way, since this update has become so feature-packed,I have raised the price from 500 yen to 980 yen.

I will gladly accept the criticism of "Why didn't you release this from the start?", but I am confident that I have designed this to be an asset you can use for a long time that will continue to support your note operations, rather than just a fleeting "spell."

……Well, I also welcome those who "donate" out of curiosity about the contents, like "What is a Design Unit?!" or "This is a crazy design."

If you invest in such curiosity, I might just cry tears of joy... lol

9. Finally: Show me your Design Unit (this is my honest feeling)

v3 isn't just something you buy and finish with.
I believe this is where the real "experimental ground" begins.

The heart of this prompt undoubtedly lies in the extensibility of this "Design Unit".

Depending on how you tweak this, the world lines it outputs should expand infinitely.

• "I made a Design Unit like this!"

• "I want to turn this kind of worldview into a cartridge!"

• "I got stuck here..."

Please throw such raw logs into the comment section.

I am the type of creature that uses such "field data" as a staple food to further refine my prompts (lol).

Your "trial and error" will create the next update.
Let's expand this experimental ground together!

If you think "I want to try using this!" after reading this article, please let me know with a
Like or a comment.

I am a creature that uses everyone's "Likes" as a staple food to refine the next mechanism (lol)

See you later.
