Software, made from your words.
You write the spec and its scenarios. AI agents write the code and test it until it converges, with little to no human review.
It starts as a spec.
Say what you want in plain language: who it’s for, what it should do, the cases you already know about. That spec is the raw material: everything that follows is shaped from it.
Then say how you’ll know it works.
Scenarios spell out what should happen, step by step. They become the checks the software has to pass.
- Given
- an order is open
- When
- the customer cancels it
- Then
- they get a confirmation
Agents write the code.
Agents take the spec and the scenarios and build against them: front end, back end and everything in between.
The harness keeps them honest.
The agents run your scenarios through test harnesses. What fails goes back for another pass. What passes moves on.
Then it converges.
Write, test, fix, again — until every scenario passes and each line of your spec is met. The work converges with little to no human review.
Builders. Build the whole product.
For entrepreneurs and builders: front end, back end, marketing, design and more — each layer specified, built and checked on top of the last.
Product managers. Run the company’s code on your machine.
Make the improvement yourself, on the company’s own source, and bring your engineers a working suggestion. Stop waiting for your engineers to be proactive.
Small businesses. Make the tool your office is missing.
Build your own admin and productivity tools for the rest of the team — say, a front-desk app for a medical office that makes routine tasks faster and more organised.
Knowledge workers. Put your whole desktop to work.
Connect your mail app, Signal, Discord, Slack and the browser into workflows that make you more productive and more efficient. Take full control of a desktop that already holds all your files, securely, no cloud required.
Start with a sentence.
Describe what you want built, in your own words. That becomes the spec, and the spec becomes software.
