Download Stash for Mac and Windows: Install Guide

Which Stash Are You Looking For?

Start here, because "Stash" is a crowded name and Google mixes the products together. This Stash is a Mac and Windows clipboard and screenshot tool built for developers who work with AI coding agents. You copy, you screenshot, you paste into Claude Code or Cursor, and the capture carries real context the agent can read.

Here is how it differs from the other things called Stash, so you know you are in the right place:

• The self-hosted media organizer that ships stash-win.exe. Open source, runs a local server, catalogs a media library. Different product, different site. Not this.
• The rules-based network proxy app for routing traffic on mobile and desktop. Also not this.
• The investing service that helps people buy fractional shares. Same name, unrelated company. Not this either.

If you landed here searching "stash for windows" or "stash-win.exe" and you wanted the media organizer, this is not it, and there is no hard feelings in saying so. If you wanted a capture tool that makes your screenshots readable to an AI agent, keep reading. That is what this Stash does.

Download Stash for Mac

Grab the Mac app first, because it is where everything lives. Clipboard history, screenshot capture and annotation, screen recording, the local MCP server, and the structured capture reports are all in the macOS build.

Stash is distributed straight from yourstash.ai and updates itself through Sparkle, so once it is installed you get new versions without hunting for a download page again. It is a menu bar app. No Dock window, no clutter, just a click in the top-right corner when you want your history or a capture.

Download Stash for Windows

Stash ships a Windows build too, so a PC in your setup is not a dead end for captures. Download it from the same install page and run the installer.

Be honest about what you get: the Windows build focuses on capture. The Mac app is where the MCP server and the full AI capture bundle run today. If your agent workflow is centered on Claude Code or Cursor querying your captures, the Mac app is the one that talks to them. If you mostly need to grab a screenshot on a PC and get it into a chat, the Windows build does that.

The Chrome Extension

The Chrome extension captures what is in your browser tab. Full-page grabs, a region, the visible viewport, without leaving Chrome. It is the answer to the "full screen screenshot extension chrome" search, and it pairs with the desktop app rather than replacing it.

Install it from the Chrome Web Store link on yourstash.ai/install. Handy when the thing you want an agent to see is a rendered web page and you are already in the browser.

System Requirements

macOS asks for two permissions the first time you run Stash. Screen Recording lets it capture the screen. Accessibility lets it register global hotkeys and read the accessibility tree of the app you captured, which is a big part of how a Stash screenshot carries context an agent can use. You grant both once and forget about it.

Install on macOS

1. Download the .dmg from yourstash.ai/install.
2. Open the .dmg and drag the Stash icon into your Applications folder.
3. Launch Stash from Applications. Look for the icon in the menu bar, top-right.
4. Grant Screen Recording and Accessibility when macOS prompts you. If you skip a prompt, you can turn each on later in System Settings under Privacy and Security.
5. Sign in to activate your license. Your clipboard history and captures stay local; the account is for licensing.
6. Optional but worth it: run the one-command MCP installer at yourstash.ai/install-claude.sh to wire Stash into Claude Code, Claude Desktop, and Cursor automatically.

That is it. Press Command Control S to take your first screenshot and you will see the context banner render along the bottom of the image.

Install on Windows

1. Download the Windows installer from yourstash.ai/install.
2. Run the installer. If Windows SmartScreen warns on a fresh download, choose More info, then Run anyway.
3. Launch Stash and allow screen capture access when prompted.
4. Sign in to activate your license.

Capture, then paste into your chat the same way you would on a Mac.

Which Build Has the AI Features

Short version: the Mac app. If the reason you want Stash is that your screenshots and recordings should be readable by an AI agent, install the Mac app.

That is where the parts that matter for agent work live. Every screenshot carries a context banner and XMP metadata with the app, window title, URL, OS version, and display info. Editor and terminal captures include an accessibility tree and dev context like the active file path and cursor position. Every recording produces a structured report an agent can read instead of the raw MP4. And a local MCP server lets Claude Code, Cursor, and other clients list, search, and fetch your captures by ID.

Those pieces are current with the tools you already run. Claude Opus 4.8 and Claude Sonnet 5 read Stash captures through MCP, and Cursor 3.11 connects to the same local server. The Windows build and Chrome extension get captures out of more places; the Mac app turns them into context an agent can ground on. If you want the fuller picture of that setup, the best Mac tools for vibe coding rundown puts Stash next to the rest of the stack.

Rule of thumb: install the Mac app if you code with an AI agent. Add the Windows build or Chrome extension when you need to capture somewhere the Mac app is not.
