Mac PowerTools is a small menu bar utility for macOS. It bundles the handful of things I reach for a dozen times a day behind global shortcuts that work in any app, including full-screen ones: screenshot to the clipboard, screenshot to text, a pinned floating screenshot, proofreading and other text actions on the current selection, a searchable clipboard history with a calculator, and window snapping.

Six tools, one menu bar icon

  • Screenshot to clipboard (⌘⇧S). The native crosshair and window picker, but the image lands on the clipboard instead of the desktop.
  • Screenshot to text (⌘⇧O). Capture any text on screen and get it back as editable text, recognized on-device with Apple's Vision framework.
  • Pinned screenshot (⌘⇧2). A capture that floats above every window as a reference.
  • Proofread (⌘⇧P). Select text in any app and replace it with the corrected version. The original stays on the clipboard, so ⌘V undoes the change.
  • Text actions (⌘⇧A). Translate, summarize, change tone, fix code, change case, sort or de-duplicate lines, and count words from a Spotlight-style chooser.
  • Clipboard history (⌘⇧C). Search text, images, and files you copied, pin favorites, paste as plain text, or type 15% of 80 and 10 km to mi for an instant answer.
  • Window shortcuts (⌃⌥ arrows). Halves, maximize, center, or move the focused window to the next display.

How it works

The app registers global hotkeys and drives the frontmost app with synthesized ⌘C and ⌘V, so text actions work in every app that supports copy and paste. Screenshots, OCR, history, and the calculator never touch the network. AI actions use Apple Intelligence when it is available, fall back to the macOS spelling and grammar checker when it is not, and can be pointed at OpenAI, any OpenAI-compatible endpoint, or a local Ollama or LM Studio server. API keys live in the Keychain, and clipboard content that password managers mark as concealed is never recorded.
