Lovingly nurtured over time—our AI copywriter, Tetra-X.ai. We’ll sell—just a little.

Dear believer in the power of words,
 

We’re offering Tetra‑X.ai—just a little.

We hate hard sells and sales calls.
We’ve never done them, and we never will.
 

We invented this system to help build a future where advertising isn’t the “bad guy.” That’s the whole point.
 

Tetra‑X.ai—the product we’re building—is a completely new system for creating brand messages that resonate.
We’ve secured a patent.
 

—That said,
as we kept asking what would make the most people happy and what approach would be best,
time passed—without even a price set.
 

Fortunately, thanks to the relationships we’ve been lucky to build, we’ve met strong partners and companies.
Behind the scenes, a robust future is steadily taking shape.

So this time, we’ve prepared a simple trial plan—
a step just before the finished form we call “co‑creation.”

First, please judge only the skill of the AI copywriter.
 

If either of the following sounds like you—

1. Shop owners
   　→ Let’s build a bank of ready‑to‑use copy.

2. Startups & new ventures
   　→ Use it to brainstorm and sharpen your value proposition.

Price: ¥50,000 for 10 options to start.
We’ll redo it as many times as needed until you’re satisfied.
If it still doesn’t meet your needs, we’ll refund you in full.
