# What is Sixth?

> An introduction to Sixth, the AI coding agent for VS Code.

Sixth is an AI coding agent that lives in VS Code. You describe what you want in plain language, and Sixth reads your project, plans the work, edits files, runs commands and checks its own results, asking for your approval wherever you want it to.

It works with the frontier models out of the box (Claude, GPT, Gemini, Grok, Kimi, DeepSeek and more) through your Sixth account, so there's no API key to set up unless you want to bring your own.

## What Sixth can do

<CardGroup cols={2}>
  <Card title="Build and fix code" icon="code" href="/features/chat-interface">

  <Card title="Design Studio" icon="palette" href="/features/design-studio">

## How you stay in control

* **Approvals.** Sixth asks before it edits files, runs commands or uses external tools, unless you've [auto-approved](/features/auto-approve) that kind of action.
* **Checkpoints.** Every change is snapshotted, so you can [compare and restore](/features/checkpoints) your files, the conversation, or both.
* **Rules.** [Sixth Rules](/features/sixth-rules) give Sixth your project's conventions on every task.
