Hi Product Hunt 👋
I built Gengo because I kept interrupting my workflow to search for commands, translations, formatting examples, and tiny snippets I could never remember.
The idea is simple:
1. Select text anywhere on macOS
2. Describe the transformation you want
3. Gengo instantly replaces the selected text
Some examples I use every day:
• Convert GitHub URLs into GitHub Pages URLs
• Turn terminal errors into fix commands
• Generate ffmpeg commands from plain English
• Convert JSON into TypeScript types
• Rewrite Japanese text into natural English
• Format messy SQL instantly
Instead of opening a browser or ChatGPT every few minutes, Gengo keeps the workflow inside the current app.
I’d love to hear what kinds of text transformations you’d want to use it for!
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.
The GitHub URL pages conversion example immediately clicked for me. Tiny repetitive tasks like that add up massively over time for developers.
