Will It Sell?

Know if your digital product will sell before you create it.

You gather real evidence that someone wants it and figure out how much each sale would leave you. In 7 days, one hour a day, you end up with your Verdict: go, adjust, or drop it.

Find out if your digital product will sell, and how much it will make you, before you create it. A 7-day system: a 48-page PDF, an Excel worksheet with a Demand Radar, a Real Profit Calculator, and a Viability Verdict, plus a prompt kit.

  • One-page Viability Verdict that fills itself in
  • Calculator with Hotmart, Stripe, and Mercado Pago fees
  • Script for 5 conversations that asks about facts, not opinions

The problem

What if you spend weeks creating something nobody buys?

Making a digital product with AI takes an afternoon now. That's why there are thousands, and most sell little or nothing: they were made without knowing if anyone wanted them and without running the numbers on what each sale costs to get. Asking AI what to sell gives you the same answer it gives everyone.

The result

What changes once you have it.

Evidence, not hunches

Searches, ads that have been running for months, real market complaints, and 5 conversations with people living the problem.

Your numbers before you invest

How much you keep per sale after IVA (Mexican VAT), fees, and ISR (Mexican income tax), and how many visits you need to hit your goal.

A clear decision

Your Verdict says go, adjust, or drop it, with the rule written down before you see the results so you don't fool yourself.

What's included

Three files, one decision

48-page PDF

The system in 10 chapters, one step a day, with “Done when” at every step and illustrative examples.

Excel worksheet

Demand Radar, ads, complaints, interviews, Real Profit Calculator, and Verdict. Also works in Google Sheets.

Prompt and template kit

8 AI prompts and 6 templates to copy: interview, invitations, waitlist, and post-mortem.

Real Profit Calculator

Hotmart, Stripe, and Mercado Pago fees and 2026 ISR withholding already loaded, editable if they change.

Future editions included

If I update fees or rules, the new version shows up in your account at no extra cost.

Here's what it looks like inside, before you pay.

Actual excerpt

Template T04: problem conversation script

QUESTIONS (in this order) 1. Tell me about the last time you had to deal with [PROBLEM]. What happened? 2. What did you try to solve it? What worked and what didn't? 3. Did you pay for anything to solve it (a course, a book, a person, an app)? Roughly how much? 4. What was the most frustrating part of the whole process? 5. How much do you care about solving it now, from 1 to 10? Why isn't it a 10? 6. If you had a magic wand today, which part would disappear? 7. Do you know anyone else going through this who I could talk to?

Inside

Real pages, exactly as you'll download them.

Four real pages: the 7-day plan, the decision table, the Calculator with its example, and a prompt. Click any of them to see it full size.

Who it's for

It's for you if you're:

  • Professionals and skilled tradespeople who want to turn what they know into a digital product
  • People with a product idea who want to know if it's worth it before investing weeks
  • People who already launched something that didn't sell and want to know if the idea was the problem

It's not for you if:

  • People looking for a “done-for-you” product to resell without creating anything of their own
  • People who aren't willing to talk to 5 people living the problem
  • People expecting an income promise: here you decide with evidence, not faith

How to use it

  1. 01

    Research

    Days 1 to 4: your advantage, what people search for, who already charges for something similar, and what the market complains about.

  2. 02

    Ask and calculate

    Days 5 and 6: five conversations that ask about facts, not opinions, and your real numbers in the Calculator.

  3. 03

    Decide

Questions

Before you buy.

Do I need to already have a product idea?

No. Chapter 2 helps you come up with 3 candidate problems based on what you already know how to do. If you already have an idea, the system puts it to the test.

Do I need to pay for tools or ads?

No. Everything is done with the free version of ChatGPT, Claude, or Gemini, Google Trends, the Meta Ad Library, and Excel or Google Sheets. You do need a computer and one hour a day for 7 days.

Does it guarantee my product will sell?

No, and nobody honest can. What it gives you is evidence and numbers to decide before you invest. If your verdict says “drop it,” you still win: you saved yourself weeks of work on something that wasn't going to work.

What if it doesn't work for me?

You have a 15-day guarantee, under the site's refund policy. Write to me at [email protected] and we'll sort it out.
