Retext

Select text anywhere in Windows. Press a hotkey. Get it corrected in place.
Grammar, spelling, punctuation, capitalization — fixed in ~1 second.

How it works

Select text → Ctrl+Shift+R → text corrected in place

Retext sits in your system tray. When you trigger the hotkey, it:

1. Copies the selected text via Ctrl+C
2. Sends it to the Gemini API for correction
3. Pastes the corrected version via Ctrl+V
4. Restores your original clipboard

The language is auto-detected — works with any language Gemini supports.

Quick start

1. Download Retext.exe from Releases
2. Get a free API key at aistudio.google.com/apikey
3. Run Retext.exe — it appears in the system tray
4. Right-click the tray icon → Settings → paste your API key → Save
5. Select text anywhere → press Ctrl+Shift+R

Settings

Right-click the tray icon → Settings:

Setting	Default	Description
API Key	—	Your Gemini API key (get one free)
Model	gemini-2.5-flash	Any Gemini model name
Hotkey	Ctrl+Shift+R	Click Record to change

Config is stored in %APPDATA%\Retext\config.json. The API key is stored securely in Windows Credential Manager.
