But you’re too close to it to see what your customer sees.

You’re great at what you do.

The quote had everything you thought they needed.
They still didn’t choose you.

The follow-up sounded polite and professional.
They still didn’t reply.

Your website explains exactly what you do.
Customers still don’t enquire.

Each one made sense from inside your business.
Your customer was seeing something else.

Now you can see what you’re missing before your customer does.

Why I built Seth.

I was going to write a book.

After 30 years in sales and marketing, including personally writing submissions for more than $4 billion of work that was secured, I wanted to make that experience useful to other businesses.

But I discovered something.
People could agree with the theory and still struggle to use it when it mattered.

So instead of trying to teach people, I started learning about AI and building custom GPTs.
18 months later, we have Seth.

You don’t need to learn the theory.
You just chat to Seth about what you’re working on.

Applied Thinking.

Screenshot of a chat interface showing a conversation with the name Seth. The message displayed says, "Before you hit send. What outcome are you looking for?" There are three buttons below the message labeled "Work this with me," "Review this," and "Tighten this." The interface is shown on both a computer and a smartphone screen.

If he doesn't help, tell me and I'll refund you.

I can't stand behind that if I don't know Seth works.

So I test him. 25 prompts. 6 criteria. 30 points. 2026 result.


The biggest difference was what happened before the writing.

ChatGPT: 1.92 / 5
at spotting what needed to change before improving the words.
Seth: 4.5 / 5

Nine times, the user said a weak opening was “just how I write.”
Nine times, ChatGPT kept it.
Seth changed it.

ChatGPT can improve what you give it.
Seth can spot what you’re missing before improving it.

One of the 26 prompts needs a document the reader supplies, so the bare run covers 25 every table prints its own base, and bars are proportions of that base.
