About this app
Text confidently in English — in every app on your phone.
ControlG fixes your writing right where you type it. Write your message the way it comes naturally, add a short trigger like "gg" at the end, and ControlG instantly rewrites it into clear, correct, natural English — inside WhatsApp, Gmail, Messenger, Facebook, or any other app. No copy-paste, no switching apps.
HOW IT WORKS
1. Type your message anywhere
2. Add your trigger (like "gg") at the end
3. Watch it become polished English before you send
WHY CONTROLG IS DIFFERENT
• Your own AI key — ControlG connects directly to Google Gemini (free tier works), OpenAI, or Claude using your own API key. No subscription to us, ever.
• Radically private — there is no ControlG server. Your words go straight from your phone to the AI provider you chose. We never see, store, or route your text. The app collects no data at all.
• Open source — every privacy claim is verifiable in our public code.
• Works everywhere — any app with a text field, in any language, rewritten into English.
• Custom actions — create your own triggers and prompts: translate, make formal, shorten, fix grammar only… you decide.
FREE TO TRY
You get 200 free rewrites — no card, no account. After that, a one-time lifetime license unlocks unlimited rewrites on Android, Windows, and Mac together.
SETUP IN 2 MINUTES
Add your free Gemini API key (the app shows you how), switch on the ControlG accessibility service, and type your first "gg".
ABOUT THE ACCESSIBILITY PERMISSION
ControlG uses Android's Accessibility Service for exactly one job: reading the text you typed in the field you're editing and writing the improved version back into that same field when you use your trigger. It is never used to collect data — there is nowhere to send it, because ControlG has no server.
