SnapRewrite

SnapRewrite is a flexible macOS AI writing assistant built around selected text. Highlight text in any app, trigger an action, and rewrite it in place without switching tabs or copying and pasting between tools. Beyond basic rewrite and polish, SnapRewrite lets you create custom AI commands for your own writing workflows. You can use built-in free models or connect your own OpenAI-compatible APIs, so the experience adapts to how you write.
