# Documentation

> CoPage is where people and AI agents work on diagrams and client decks: agents build them in an editor people can watch, checks catch what shouldn't reach the client, and people sign off. Start with the free CoPage CLI, which makes diagrams on your computer with no account; the CoPage app, for decks and teams, is in early access.

Start with the free CoPage CLI. It runs on your computer, does diagrams only, needs no account, and keeps your
diagrams in your project. Your coding agent (Claude Code, Codex, Cursor, GitHub Copilot) draws with it, and you
adjust the result in an editor in your browser. [Install it](/docs/cli#install).

For decks and teams there is the CoPage app. It holds decks and diagrams for you, your team and your agents, with
comments, checks, version history and exports to PowerPoint, PDF, SVG, PNG and draw.io. It works with the same
coding agents, and with Claude and ChatGPT as connectors. The app is in early access:
[request access](/#early-access).

## Pages

- [The CoPage CLI](/docs/cli): install it, start in a project, draw, check and export diagrams that reopen for
  editing, and what it contacts on a work computer.
- [Connect AI agents](/docs/agents): the CLI's local MCP server (`copage-local`), the CoPage app's (`copage`),
  setup for each agent, and the tools agents use.
- [Checks and check packs](/docs/checks): what checks catch, the built-in packs such as Client-ready, the check
  library, and how agents fix findings in a loop.
- [Diagrams](/docs/diagrams): AWS, Azure and Google Cloud icons, connectors, draw.io import and export, files for
  docs, and diagrams linked on slides.

## Questions

### What is CoPage?

CoPage is where pre-sales engineers, solution architects and developers work with AI agents on diagrams and client
decks. Agents build them, checks catch what shouldn't reach the client, and people sign off. Every file stays
editable.

### Is CoPage free?

The CoPage CLI is free and needs no account. The CoPage app, with decks and team features, is in early access.

### Do I need an account to use CoPage?

Not for the CLI. The CoPage app needs an account; you can request early access on copage.app.
