A clear roadmap so you never wonder what to do next

The problem

You have the idea. You're just missing the document.

You've had this idea for months. Maybe years. You know it solves a real problem. But the moment you try to move forward - you hit a wall.

Where do I even start? How do I explain this to a developer? What do I build first?

Without a clear brief, developers make their own assumptions. They build the wrong thing. Budgets blow up. And the product that ships isn't the one you had in mind.

1 weekend

to have a complete brief in your hands

Five steps. One document. Ready to send.

Each worksheet builds on the last. By the time you reach the final one, the hard thinking is already done. You're just writing it up.

~30–40 min

Is This a Good Idea?

Write the problem in one sentence. Describe three people who have it. Score your idea honestly. Write your one-line pitch.

You walk away with A clear yes or no - and a one-sentence description you can say out loud.

~30–45 min

Who Is This Actually For?

Describe the specific person you're building for. Write down their frustrations in their own words. Map what changes before and after your app.

You walk away with A vivid picture of your buyer - so every decision has a person behind it.

~30–45 min

What Do I Build First?

List every feature idea. Score each one on how often it's used and how much pain it solves. The spreadsheet sorts your list automatically.

You walk away with Your 3–5 must-have features. Everything else parked for later.

~15–20 min

How Should I Build It?

Answer 8 plain-English questions about how your app will be used, your budget, and your timeline. The spreadsheet gives you a recommendation.

You walk away with A clear answer - web, mobile, or no-code - plus a cost range for quotes.

~45–60 min

The Developer Brief

Write out each feature in full. Describe what it does, who uses it, and what "done" looks like. Add how it should feel and what success means.

You walk away with The finished document. The one you send to a developer and say: build me this.

Every template comes with a filled-in example. See a complete, worked version for a fictional app called RentEasy before you start. Ten minutes reading an example will save you thirty minutes of guessing.

Why this kit exists

"I'm a Product Manager at Oracle. Friends kept coming to me with app ideas - smart people, clear problems, genuine potential. Every time, they'd hit the same wall: they couldn't explain what they wanted to a developer. I walked each of them through this exact process. It worked every time. So I packaged it up."

Lukáš Kostka

Senior Product Manager, Oracle

"I used this before talking to my developer and it saved us weeks of back-and-forth. He actually said it was the clearest brief he'd ever received."

- Michal, Marketing agency owner

"I'd been sitting on this idea for two years. After one weekend with these worksheets, I had something I could actually show people."

- Peter, Designer

Questions

Do I need any technical knowledge?

None at all. These worksheets are designed for people who have never built an app before. If you can fill in a form, you can complete this kit.

What tools do I need?

Just a free Google account. No subscriptions, no new software, no Notion. Everything works in Google Docs and Google Sheets - tools you already know.

How long does it actually take?

One weekend. About 3.5 hours spread across two days. Saturday covers the thinking work, Sunday covers the writing. By Sunday evening, you have a complete brief.

What do I actually walk away with?

A complete document you can send directly to a developer. It covers what to build, who it's for, what features matter, how to build it, and what "done" looks like. No more blank stares when they ask for your brief.

What if I get stuck?
