AITextTune

AITextTune is a paraphrasing tool. A Windows-only text improvement tool that triggers from a double Ctrl+C shortcut and applies correction, style rewriting, summaries, explanations, translation across 25+ languages, chat prompts and text-to-speech to selected text in any application. Requires a Google Gemini API key.

AITextTune is a Windows utility that puts an AI writing assistant one keyboard shortcut away from whatever application you happen to be typing in. Rather than asking users to open a separate chat window and paste their draft back and forth, it hooks into the copy action: you highlight text, press Ctrl+C twice, and a small menu appears offering correction, style changes, summaries, explanations, translation, a free-form chat prompt, and text-to-speech playback. The result replaces or sits alongside the original text without leaving the editor. The feature set is aimed at the everyday cleanup work that slows writers down. The correction mode targets spelling, grammar, clarity and flow, while the style mode reshapes the same passage toward formal, creative or custom presets, and users can save their own style definitions. Summaries and translations cover more than 25 languages, the explain function rephrases a passage at a level matched to the reader, and the listen option reads text aloud. Because the menu is triggered at the operating system level, it works in email clients, word processors, browsers and any other software where text can be selected, and it accepts input in any language. It suits people who write across several programs and do not want a browser tab in the middle of their workflow: office workers polishing reports and emails, students working through dense material in a second language, and anyone who regularly rewrites the same content for different audiences. The practical caveat is that output quality depends entirely on bringing your own Google Gemini API key, so the app is best understood as a front end for Gemini rather than a self-contained service. Readers comparing it with browser-based writing assistants should weigh that setup step and the Windows-only distribution against the convenience of having the tool available in any window.
