Download

Quick start

From download to your first answer.

Before you start

  • Windows 10 or 11 (64-bit), macOS 12.3 or newer (Apple Silicon or Intel), or Linux x64 (tested on Ubuntu 22.04, X11 and Wayland). See the download page for each system's requirements.
  • A license key. The free trial lasts 3 days, and its key is sent to your email address. Get it on thedownload page.
  • Your own Claude account, through the Claude Code CLI signed in on your computer. Quick answers and the Claude Code destination need it. The Claude chat destination works without it.

1. Install

Download SnapPrompt for your system from the download page.

  • Windows: run the installer. SnapPrompt sits in the tray and can start when you sign in to Windows, which you can change in Settings.
  • Mac: open the .dmg and drag SnapPrompt to Applications. The app is not notarized by Apple, so macOS blocks the first launch: open System Settings › Privacy & Security and clickOpen Anyway (on macOS 14 or older, right-click the app in Finder › Open also works). If macOS says the app is damaged, run xattr -dr com.apple.quarantine /Applications/SnapPrompt.app once in Terminal. Grant Screen Recording and Accessibility when asked, then restart SnapPrompt. It sits in the menu bar and can start at login.
  • Linux: install WebKitGTK 4.1, an AppIndicator library and Tesseract (on Ubuntu:sudo apt install libwebkit2gtk-4.1-0 libayatana-appindicator3-1 tesseract-ocr tesseract-ocr-vie xdg-desktop-portal), make the .AppImage executable and run it. Or, once it is published, install the .deb withsudo apt install ./SnapPrompt_*.deb, which pulls in WebKitGTK, the AppIndicator library and Tesseract (add tesseract-ocr-vie and xdg-desktop-portal yourself). On GNOME the tray icon needs the AppIndicator extension, which Ubuntu enables by default. SnapPrompt can start when you sign in.

2. Activate your key

Without a license the app stays locked and shows the license screen. Paste your key there. Full steps, including offline activation, are in Activate a license.

3. Connect Claude

SnapPrompt uses the sign-in that Claude Code already has on your computer and stores no passwords. In Settings, the Claude page shows the connection status, offers a one-click install of the Claude Code CLI if it is missing, and helps with signing in. The CLI is downloaded from the official build.

4. Take your first capture

  1. Press CtrlShift1 (Capture and ask). On a Mac this is Control+Shift+1 too.
  2. Drag to select a region. Press Space to pick a window, or F for the full screen. On Linux with Wayland, your desktop shows its own picker instead; use its options.
  3. Type a question, or tap a chip such as What is this? or Explain simply.
  4. Read the answer in the card beside the capture, then ask a follow-up if you want.

5. Try the other destinations

  • CtrlShift2 (Full capture) opens the prompt on your default destination, Claude Code unless you change it, with folder and model choices. SeeSend to Claude Code.
  • While you type, Ctrl1, Ctrl2 and Ctrl3 switch between Quick answer, Claude Code and Claude chat.
  • AltE opens the image editor, where you canredact before sending. On a Mac, open it with Edit captureon the answer card instead (see Shortcuts).
