## What you own with Kortix, layer by layer

Every layer an AI Operating System needs is a file in the repo you own.

### 1. One git repo is the company

Your agents, the skills they share, your company memory, and every connector live in one git repo you own.

`the project repo`

```
acme-co      your whole company, as files
agents/      who does the work
skills/      how your company does a job
memory/      what it has learned so far
kortix.yaml  what each agent may touch
```

### 2. Wire each tool once

3,000+ apps in a click, plus MCP, OpenAPI, Postman, GraphQL and raw HTTP.

`connector policy`

```
Set each tool to Allow, Ask or Block, down to the arguments of each call.
Connector credentials are brokered server-side and never enter the machine.
```

### 3. Any model, your keys

Any model provider with your own keys. Or the ChatGPT plan you already pay for.

`models`

```
Runs any model
Bring your own API key from any major provider, or use ours
Or sign in with the ChatGPT subscription you already pay for
```

### 4. One cloud computer per session

Each session has its own isolated machine and branch.

`sessions`

```
Each session gets its own isolated sandbox and its own branch.
Run thousands of sandboxes in parallel on the same config, each fully isolated.
```

Source: https://github.com/kortix-ai/suna

### 5. Work lands as a change request

Session work reaches main through a change request. Merge is default-deny for agents.

`change requests`

```sh
$ kortix cr ls
# review what the agents propose
```
