Finish your AI prototype
You described an app, an AI builder gave you a project, and it almost works.
Micro · $249
A shared chore chart for your family
Paper charts get lost, fridge whiteboards get erased, and generic apps come with ads, subscriptions, and features no one asked for.
Tool · $749
A weekly meal planner that builds your grocery list
Planning dinners is one job and writing the grocery list is another, and the two rarely line up.
Tool · $749
A shared trip planner with an itinerary and a running tab
Group trips end up scattered across a group chat, a notes app, and someone's memory of who covered the rental car.
Tool · $749
An estimate request form with photo uploads for landscapers
Estimate requests often arrive as scattered texts, voicemails, and emails with a few blurry photos and no address.
Tool · $749
A simple photo proofing page for your clients
Many photographers collect picks over email threads, screenshots, or lists of file numbers.

How it works

  1. Step 1
    You describe it
    What should it do?

    Tell us what it should do, in plain English. A few sentences is plenty. If anything is unclear we ask before we build.

  2. Step 2
    We build it

    Our AI build system drafts the whole thing. Then a person reviews every screen, tests it, and fixes what the AI got wrong.

  3. Step 3
    It's yours

Yes, it's built with AI. That's the point.

Most software is built for everyone, which is why it does a thousand things you don't need. We use AI the other way around: to build exactly the thing you asked for and nothing else. A person reviews every screen, tests it, and fixes what the AI got wrong before you ever see it. You get a tool that fits your work, at a fixed price, in days, and you own the code.

Only what you need

Scoped tight, no bloat, no second screens you'll never open.

A person checks every build

AI drafts; a human reviews, tests, and fixes before you ever see it.

Yours to keep

MIT-licensed source code, hosted link, zero lock-in.

FAQ

Is hosting included?

Hosting is included for 12 months, then $9 per month, or you can self-host at any time. The source code is yours either way, with a step-by-step deploy guide at /self-host.

Who owns the code?

You do. We ship the source under an MIT license, so you can host it yourself, hand it to another developer, or extend it however you like. The repo is yours; we never gate it behind a subscription.

What if I need changes later?

Each tier includes tweak rounds during the build, so small changes before delivery are already covered. After delivery, order a new Micro for small changes; it is fixed-price and ships in a few days.

How do revisions work?

Each tier includes a set number of tweak rounds during the build. You review the preview, send us a list of changes, and we apply them before shipping. Larger reshaping, or changes after delivery, are a new order on whichever tier fits.

What can't you build?

Native mobile apps, heavy data pipelines, workflows that store regulated data such as health records or card numbers, and ongoing custom development. If what you need is a small, focused tool with a clear job, we can almost always build it. If it's closer to a full product, we'll say so before you pay.

Can it take payments or send texts?

Yes, through your own accounts. Payments run through your Stripe account and texts through your Twilio account. After delivery you paste your API keys into the applet's Connected accounts page, and from then on the money and messages go straight through your accounts, not ours. We never hold your funds or your customers' card numbers.

How exactly do you use AI?

AI drafts the whole thing from your description: screens, data, and the glue. A person then reviews every screen, tests the flows, and fixes what the AI got wrong before it ships. You get what AI is good at (speed) without the parts it is bad at (details, judgment, finishing).

What is your refund policy?

If we decide before work starts that we can't build what you described, you get a full refund, no questions asked. Once your build is underway there are no refunds; the deliverable is the hosted link and the source code.

ap·plet(noun)

A small, single-purpose piece of software: a form, a calculator, a tracker, a mini-dashboard, scoped tightly so it ships in days rather than weeks.

Applet Lab builds applets with AI, has a person review and test every one, and delivers them as a hosted link plus the MIT-licensed source code; prices start at $249 and typical turnaround is 3 to 10 business days.
