Gengo is a macOS utility that transforms selected text instantly using AI. Select text anywhere on your Mac, describe what you want, and Gengo replaces it in place. Turn GitHub URLs into GitHub Pages URLs, convert Japanese into natural English, generate terminal commands, format SQL, create TypeScript types from JSON, and much more — without switching apps or breaking your workflow.
Replacing the selection in place is the part that'd make me nervous — if I select a paragraph and the transform isn't what I expected, is there a clean undo, or am I trusting Cmd+Z to walk back exactly what got swapped? A diff-preview before it commits would calm that a lot.

That’s a great question — by default, Gengo does not automatically replace the selected text immediately.
Instead, it first shows the generated replacement candidate, and the user explicitly decides whether to apply it:
• Cmd+Enter → apply replacement
• Esc → cancel
So the workflow is designed to keep the user in control before committing any change.
For users who prefer a faster workflow, there’s also an optional auto-replace mode.
And of course, standard undo (Cmd+Z) still works as expected, so please feel free to experiment without fear 🙂
The GitHub URL pages conversion example immediately clicked for me. Tiny repetitive tasks like that add up massively over time for developers.
@eugene_marshall Exactly — that was one of the main motivations behind Gengo.
Not the huge once-a-month tasks, but the tiny “I know I’ve done this before…” moments that constantly interrupt flow.
Individually they take only seconds, but over hundreds of repetitions they become real cognitive friction.
I wanted Gengo to feel less like “opening an AI app” and more like giving macOS a native text transformation layer.
