#10 Labs · Foil

From a half-formed idea to a clear brief.

Foil is an AI interviewer. You talk through an idea, out loud or typed. It asks the next question based on what you just said, and at the end it writes a project brief you check before anyone sees it.

What it is

A first call, whenever you're ready.

Most ideas start as a feeling: the store should do more, the site is wrong somehow. A form asks you to explain it in a box. Foil asks the questions we'd ask on a first call, one at a time, and keeps digging where your answer was thin. It's for anyone with a project they can't quite put into words yet. We built it for ourselves first, to think out loud on a walk, and now it's the first step for people who reach out to us.

How it works

Ask, listen, ask better.

The interview is a loop. Each question is written after your last answer, not picked from a list.

  1. 01Your idea

    Pick what it's about (a Shopify store, a WordPress site, design, search and AI) and how you want to talk: tell it all at once, answer questions, or a bit of both.

    1. 02Foil asks

      One question, read out loud and shown on screen.

    2. 03You talk

      As long as you need, up to two minutes. Say "I'm done" or tap Done. Silence never moves it on.

    3. 04It follows up

      The next question comes from what you said. It digs into thin answers and pushes back on easy ones.

    repeats 6 to 8 times
  2. 05The brief

    After six to eight questions, Foil writes a brief: what it is, what matters, open questions and what could go wrong.

  3. 06You confirm

    You read it, fix anything that's off and send it. Nothing reaches us until you do.

The interview that never interrupts

What Foil does while you think.

Being cut off mid-thought is the worst part of talking to a machine. So silence is never the signal to move on.

  1. 0sYou stop talking

    Foil waits. No beep, no prompt.

  2. 15sA gentle check-in

    "Take your time. Say I'm done when you're ready."

  3. 35sOne more check-in

    Still listening, still not moving on.

  4. 60sIt pauses

    Your answers are kept, and you can pick up later, on any device.

What a session looks like

A bakery, three questions, one brief.

An invented interview. The owner of a two-location bakery wants online orders for holiday pies. Watch how each question comes from the answer before it.

FoilWhat do you want to build, and why now?

OwnerEvery November our phones melt down with pie orders. I want people to order online and pick a pickup time.

Opens wide. You can say as much or as little as you like.

FoilWhen the phones melt down, what actually goes wrong: missed orders, wrong orders, or more pies than the ovens can bake?

OwnerMostly the ovens. We say yes to more than we can bake the day before Thanksgiving.

Follows up on your own words, "melt down", instead of moving to the next topic.

FoilSo the real limit is how many pies you can bake each day, not taking orders. Should the site stop selling a pickup day once it's full?

OwnerYes. That alone would save us.

Pushes back. It names the real problem before you've said it.

Listening. Say "I'm done" when you're finished.

The brief

Holiday pie preorders with pickup times

What it is
Online preorders for holiday pies, with pickup times at both locations.
What matters most
Baking capacity, not ordering, is the bottleneck. Each pickup day needs a limit that closes it when it's full.
Open questions
Do both locations share one bakery? Deposit or full payment up front?
What could go wrong
Limits set too high. Customers who miss pickup. Staff who can't see the day's orders at a glance.
Next step
A short call to size it up.

You see the brief first. Change anything, then send it. Your voice recording isn't kept: it's turned into text and deleted.

What makes it different

It listens like a good interviewer.

  • Follow-ups, not a form

    Every question is written after your last answer. Thin answers get a second look, and easy answers get pushed on.

  • It never cuts you off

    You decide when you're done. Silence, pauses and "um" are fine.

  • You confirm the brief

    Nothing reaches us until you've read the brief and sent it.

  • Talk or type

    Talking goes deeper than typing for most people, but the same interview works with a keyboard.

What we learned building it

Talking goes deeper than typing.

  1. Voice was the big bet, and it paid off

    The question that could have killed Foil was whether talking beats typing to a chatbot. In our first real session it did: talking went further, and it worked while doing something else, like watching TV or walking.

  2. Silence isn't a turn signal

    Our first version moved on after a short pause, and people started filling every gap with "um". Now only you end your answer.

  3. Waiting feels longer out loud

    A nine-second gap between your answer and the next question felt broken. We cut it to about five and play a short "Got it" right away, so it never feels like the line went dead.

  4. Shorter wins

    A long interview loses people. We aim for six to eight questions and cap each answer at two minutes, with a countdown, so a long recording can never be lost.

  5. The voice matters

    The first voice sounded robotic. We auditioned several and picked the one with the most personality, then had it speak each line in one or two pieces, because stopping after every sentence sounded jerky.

  6. iPhones start silent

    On iPhone the first version recorded nothing, and later the first question played silently. Both came down to how Safari handles audio before you tap. Fixed, but only by testing on a real phone.

One engine, many apps

Foil turned out to be an engine, not a product. Each use is a set of questions, an interviewer and a place for the result. The same loop turns a spoken brain-dump into a work ticket for our team, and runs a household inventory where you ask where something is.

The app we didn't build

NeatFreak was an older idea of ours: a voice app for cataloging what you own and where it is. Before building it, we tested demand. The answer was no. Free apps set the price people expect, voice capture is already common, and one wrong answer about where something is breaks trust in the whole thing. So we built a small version inside Foil, for our own house, and kept the lesson: test demand first, and reuse the engine you already have.

What it means for clients

The same patterns, on your site.

Foil is how we start projects now. The pieces inside it are the ones we bring to client work: an AI that asks good follow-ups, and a person who confirms the result before it goes anywhere.

  • Smarter intake

    A quote or project form that asks follow-ups and hands your team a brief instead of a paragraph in a box.

  • Product finders that listen

    Shopping help that asks the next question based on the last answer, not a fixed quiz.

  • Customer interviews at scale

    Ask every customer the same opening question, follow up where it counts and read the patterns.
