Transform your casual gibberish into workplace poetry without paying Chrome's "developer tax"
ProMessage is your secret weapon against sounding unprofessional in workplace communications. This Chrome extension transforms your hastily typed, emoji-filled messages into polished, corporate-approved prose with just one click.
Why pay $5 to the Chrome Web Store gatekeepers when you can deploy this extension yourself in under 5 minutes? That's a whole $5 you can put toward your coffee fund!
✅ One-click conversion from casual to professional tone
✅ Works on any website with text inputs (email, LinkedIn, Slack, etc.)
✅ Powered by Google's Gemini AI (using your own API key, because privacy!)
✅ Minimalist black & white design that won't make your browser look like a clown car
✅ FREE to use (take THAT, Chrome Web Store!)
Already saved $5! That's like 45% of an avocado toast!
- Open Chrome (yes, the irony isn't lost on us)
- Navigate to
chrome://extensions/ - Toggle on "Developer mode" in the top right corner (the REAL developer mode, not the $5 version)
