# Speed up with Sub0 AI

Sub0 AI is your built-in backend assistant. It helps you generate production-ready database models and APIs in minutes.

Describe what you want to build. Sub0 AI handles the syntax, structure, and starting point.

***

### From idea to backend

Sub0 AI can generate:

* Complete Sub0 database models
* API specifications
* Validated payload schemas
* Relationships, indexes, and policies

All from a plain-English prompt.

***

### How It Works

1. Describe your backend in plain English
2. Sub0 AI generates your database models
3. Sub0 AI generates your API specifications
4. You review, adjust (if needed), and deploy

No boilerplate. No setup. No guesswork.

***

### Environment variables

When Sub0 AI generates API specs:

* All required **environment variables** are automatically detected
* Variables are **created and recorded** in the **Custom Env** section
* Secrets and configuration values are never hardcoded

You don’t need to manually track or remember environment keys.

* Is fully editable after generation

You are always in control.

***

***

### Human + AI, Not Magic

Sub0 AI does not lock you in. It accelerates the starting point.
