# Introduction

> The editor whose AI actually understands your code.

V3Code is an intelligent code editor — a fork of VS Code — built by KandD Labs. It runs
locally, remembers what it learns across sessions, and exposes structural, LSP-backed
intelligence ("Context Bridge") to any agent over MCP.

## Why V3Code

* **It knows your code.** A local semantic index plus the Context Bridge mean the agent
  sees structure — symbols, references, types — not just text. Ask what breaks if you
  change something and it already has the map.
* **It remembers.** Persistent memory carries context across sessions, so the agent
  stops being a smart stranger every time you open it.
* **It runs on your machine.** Your code never leaves your hardware. No upload, no
  training on your work.
* **Bring any model.** Route work across fast, cheap models and reserve premium models
  for the hard calls — or bring your own keys.

## The four modes

V3Code has one agent with four modes you switch between:

| Mode       | What it does                                      |
| ---------- | ------------------------------------------------- |
| **Ask**    | Answer questions about the codebase.              |
| **Plan**   | Lay out an approach before changing anything.     |
| **Agent**  | Execute multi-step work with tools.               |
| **Design** | Generate on-brand UI from a locked design system. |
