How to put together a brief anyone can work from

Five common cases where you have to explain to another person what you want — from a kitchen renovation to choosing a job. About twenty minutes of conversation, and at the end a document you can send to whoever is doing the work. It's free right now.

How to explain to a contractor what exactly needs doing

You say “I need the kitchen redone” and get three quotes you cannot compare: each one priced something different. The conversation takes twenty minutes and ends with a document you send to all three.

With eXtellactREQUESTTHREE DIFFERENT QUOTESBRIEFTHE SAME FIELDS FOR ALL THREE
The quotes are finally comparableThis is how eXtellact works
What gets established
Where the work stops, what stays from the old kitchen, who buys materials, what “done” means to you
What you end up with
A one-page brief: what is decided, what you are assuming, what is not established
Why it matters
Quotes become comparable on substance, not only on price
The engine

Is the strip-out part of the job, or are you doing that yourself? Both the timeline and half the quote hang on it.

P2 · A website, an app, automation

How to write a spec when you are not a technical person

“Build us a website” is the kind of request an honest supplier answers with a five-fold range. The questions are about people and what they need to do, not about technology, so you can answer in plain words.

Why it matters
Pricing becomes possible, and “we understood it differently” shows up early

Who exactly will come back here more than once? Until I know that, any list of pages is a guess.

P3 · A choice where being wrong is expensive

How to decide when the options look equally good

A job, a move, a school, any large choice. The product does not advise and does not vote — it pulls into the open what you know for certain, what you are assuming, and what you have never checked.

I thought it was a choice between money and interest. It turned out to be between six months of risk and three months of savings.

P4 · A big purchase or equipment

What to establish before you walk into the showroom

A seller asks questions that fit their catalogue — that is how their job works. Here the questions fit your task, and you arrive with a list of requirements instead of hoping to be advised.

How many people will be working on this at the same time a year from now? Until that is known, picking capacity is a lottery.

P5 · Your own idea with no structure

The idea is there, the structure is not — where to start

An idea arrives whole, with not one detail in it. It gets taken apart, and what you do not know is marked as unknown — instead of being filled in with a plausible guess.

What gets established
Who needs this, what has to be true for it to work, what gets tested first

Sometimes the answer is no — and that is the best outcome: the plan falls apart before the money goes in

I checked. In our case you need a separate certified kitchen — a home one does not qualify.

Frequently asked questions

Is this only for IT projects?
No. It applies anywhere you are buying a service and have to explain what you want: renovation, a lawyer, an accountant, a designer, a move, training, equipment.
How long does it take?
About twenty minutes, one question at a time. You can leave and come back — the idea is kept.
How is this different from just chatting with an AI?
A chat model answers confidently even where it does not know. Here it is the other way round: a gap is marked as an open question and reaches the brief as a gap, not as a plausible guess.
What do I get at the end?
A one- to two-page brief: what is known for certain, what is assumed, what is still to be established. It downloads as a file and opens by link.
What does it cost?
Free right now. There is no payment, only a daily limit on conversations so the service doesn't get overwhelmed. When paid packages appear, we'll say so in advance.
What if it turns out the idea does not work?
That is the most valuable result there is. The plan falls apart in twenty minutes instead of six months, and not at your expense.
