# Desktop app

Download the desktop app from [thymer.com/desktop](https://thymer.com/desktop), install it, and sign in.

Two extra features the desktop app enables:

- [Markdown Mirror](../markdown-mirror.md) keeps a folder of Markdown files in sync with the workspace, both ways. Set it up in **Settings → Markdown Mirror**.
- The MCP server lets other AI apps read and edit your workspace using tool calls. Turn it on in **Settings → MCP (AI Agents)**. In the browser, the same is done with the `thymercli` companion. See [Connect an AI agent with MCP](../ai-agents-and-cli/connect-an-ai-agent-with-mcp.md).

The mirror runs while the app is open with that workspace selected. Both integrations work on the computer they run on; sign in on a second machine and set them up there separately.

## Updates

The app checks for updates by itself, downloads them in the background, and asks to restart with **Install Now** when one is ready. **Settings → Check for Updates**, or **Help → Check for Updates...** in the menu bar, checks right away.

## Menus

**View → Reload** reloads the window, and **Force Reload** reloads it without the cache. **Help → Documentation** opens these docs, and **Help → Web Inspector** opens the developer tools for plugin work. The accounts window, which lists your accounts, has **Troubleshoot...** in each account's menu: it opens the diagnostics page; see [The diagnostics page](../help/troubleshooting.md#the-diagnostics-page).
