Software that grows.
You've felt this.
The blank editor. The project that was exciting for a day and exhausting by the end of the week. The gap between what you could imagine and what you could actually make.
You're not bad at this. The approach is just... wrong.
What if the hard part was never you?
// what is a seed?
A program that grows itself.
You give it instructions — plain language descriptions of what you want. Seed figures out how to get there, evolving across generations. Each generation builds on everything before it. What starts rough becomes real, working software — shaped by you, grown by Seed.
// evolution in action
Every generation is smarter than the last.
First sprout
The idea takes root. Structure begins to emerge.
Structure emerges
Patterns form. The shape becomes clearer.
Features work
Real capabilities appear. Something usable takes shape.
Something you couldn't have designed by hand
Polished, evolved, uniquely yours.
Seed doesn't just write code — it evolves it. Every generation learns from the ones before. Mistakes are remembered. Successes compound. The longer it grows, the better it gets.
One seed, infinite forms
It evolves into whatever you need.

// how it works
Three steps. No code required.
01
Describe
Tell your Seed what you want in plain English. No syntax, no configuration files, no technical knowledge required.
02
Grow
Your Seed evolves across generations. Each one is smarter than the last. You can see the progress in real time.
03
Shape
Redirect when needed. Refine what you asked for. The Seed responds and adapts. The result is uniquely yours.
// grown with seed
Real Seeds. Real software.
“I described a recipe organizer. 50 generations later it had features I never thought to ask for.”
“My budgeting tool started as three sentences. Seed turned it into something I use every day.”
“I don't write code. I just told it what I wanted and watched it figure things out.”

FAQ
Common questions
A Seed is a program that grows itself. You plant an idea — 'a personal budget tracker,' 'a recipe organizer,' 'a short story' — and the Seed evolves it across generations into working software. Each generation builds on everything before it.
A Shaper is what we call the person guiding a Seed's growth. You're not writing code or managing technical details. You're giving instructions, watching how the Seed evolves, and redirecting when needed. Think of it as the difference between building a house and growing a garden.
Most AI tools give you a single response and move on. Seed evolves — it grows across generations, remembering what worked and what didn't. Generation 20 is dramatically better than Generation 1 because it's learned from every generation in between.
Fertilizer is domain expertise packaged in a format your Seed can absorb. Want to grow a web app? Web Development Fertilizer gives your Seed a head start. Want to write a novel? Writing Fertilizer helps it understand narrative structure. Your Seed works fine without Fertilizer — it just grows faster with it.
No. You give instructions in plain language. Seed handles everything technical. If you can describe what you want, you can grow it.
A Mac with Apple Silicon running macOS 26 (Tahoe) or later, and an API key from an AI provider (OpenAI, Anthropic, Google, or xAI). Garden is free to download. A one-time $9.99 license unlocks unlimited Seeds and full size.
Yes. The full Seed engine — CLI, TUI, every feature — is free and open source on GitHub. Garden is the macOS app that makes growing Seeds visual and easy. You can use Seed without Garden, but Garden is the experience we recommend for most Shapers.
