# Augment Code

> AI coding assistant built for large, real-world codebases — a Context Engine that indexes the whole repo, with agents, chat, and completions in IDEs and a CLI.

Augment Code is an AI coding assistant built for large, real-world codebases. Its Context Engine indexes the whole repo so agents, chat, and completions reason over your actual architecture rather than a few open files. It runs in VS Code and JetBrains IDEs and as the Auggie CLI. Proprietary, with a free trial and paid plans.

Augment Code is an AI coding assistant built for large, real-world codebases. Its defining feature is a **Context Engine that indexes the whole repository** — across many files and even multiple repos — so the model reasons over your actual architecture, call relationships, and conventions rather than just the files you happen to have open.

It is aimed at engineers working on big, established repos where generic completions lose the thread. Augment surfaces its agents, chat, and completions inside VS Code and JetBrains IDEs and through the Auggie CLI, so it fits an AI-assisted workflow whether you stay in your editor or drive tasks from the terminal.

## Highlights

- **Whole-repo Context Engine** — indexes large, multi-repo codebases and retrieves the slice a task actually touches, so answers and edits are grounded in your real architecture.
- **Agents for multi-step tasks** — agents can plan and carry out changes across files, with related products for automated code review and a CLI-driven workflow.
- **IDE extensions and a CLI** — runs as extensions for VS Code and JetBrains, plus the Auggie CLI that brings the agent and Context Engine into the terminal.
- **Codebase-aware chat and completions** — chat and inline completions draw on the indexed repo, so suggestions follow existing patterns instead of inventing new ones.

## In an AI-assisted workflow

Augment fits alongside your existing setup: install the IDE extension or the CLI, let it index the repo once, then ask it to explain, change, or complete code with full-codebase context. For more on how it sits next to other assistants, see [Cursor vs. Claude Code vs. Copilot vs. Windsurf (2026)](/guides/prompting/cursor-vs-claude-code-vs-copilot-vs-windsurf-2026).

```bash
# Install the Auggie CLI and run it in a repo (verify current command on the docs)
npm install -g @augmentcode/auggie
auggie
```

> [!TIP]
> The value of a context engine shows up most on large, unfamiliar repos — point it at a service you don't fully know and ask how a change ripples through callers before you start editing.

## Good to know

Augment Code is proprietary, not open source. It offers a one-time free trial and paid plans that have spanned individual, team, and enterprise tiers on credit-based usage; Augment has revised its plans and positioning over time, and has signaled changes to how its IDE extensions versus CLI are packaged, so confirm current plans, any free option, and supported surfaces on the official site before committing. For a broader comparison of in-editor assistants, see [GitHub Copilot vs. Cursor](/guides/comparisons/github-copilot-vs-cursor).
