Highlight text in any app, hit a shortcut (⌘⌥⌃I by default), and your selected text is replaced in place. No chat window, no copy-paste, no context switch.
About Spackle
Spackle is a macOS menu bar app for inline AI rewrites. Select text in any app, press a keyboard shortcut, and Spackle replaces your selection with an AI-rewritten version — right in place. You never leave the app you're working in.
It works anywhere macOS Accessibility can reach: Mail, Notes, Slack, browser text areas, and more.

Hit the Shortcut
