Send a screenshot to Claude Code on Windows, faster

Claude Code works best when it can see what you see. A stack trace you can paste, but a broken layout, a dialog with a code in it or a design you want to match are all easier to show than to describe. This post walks through a workflow for sending a screenshot to Claude Code on Windows without leaving the thing you are looking at.

The usual way

Take a screenshot, save it somewhere, switch to your terminal, point Claude Code at the file or paste it, and type what you want. It works, and you repeat it every time you want to show something new.

The shorter way with SnapPrompt

SnapPrompt is a Windows app that captures part of your screen and sends your question and the image to a Claude Code session in a project folder you choose.

1. Press Ctrl+Shift+2 (Full capture) and select the region. It opens the prompt on your default destination, Claude Code unless you change it, with folder and model choices. While you type, Ctrl+2 switches to Claude Code.
2. Pick a recent project folder, or set a default one.
3. Type what you want: this button is misaligned, fix this error, make it look like this.
4. Watch the session panel. It shows each step as it happens: files read, files edited, and commands run with their output.

Stay in control

You decide how much freedom Claude has. The permission levels are Ask first, Edit files itself and Plan only. When Claude wants to run a command or edit a file, the panel asks you to Allow, Always allow this command, or Deny. Always allow on a shell command is remembered for that project folder, and Settings lists those commands so you can revoke them.

When the session finishes, the right column shows the diff of every edited file. You can keep the changes or undo all of them, which puts the files back to how they were before the session started.

Tips

• Capture the smallest useful region. The error dialog, not the whole desktop.
• Say what you want changed. A capture shows the problem, but your sentence says the goal.
• Cover secrets first. If the capture shows keys or tokens, redact them before sending.
• Use follow-ups. Ask another question, or attach another capture in the same session.
• Choose the model per send. Ctrl+M in the prompt box picks the model, or set a default in Settings.

What you need

SnapPrompt needs the Claude Code CLI signed in on your computer, so you use your own Claude account. If the CLI is missing, the app can download and install the official build for you. SnapPrompt runs on 64-bit Windows only. For a quick explanation rather than edits, use the Quick answer destination instead, which runs in safe mode with no tools. Both are covered in Quick start.
