CapyBro is a Windows tray utility that brings AI to any text on your PC via a global hotkey. Select text in any application (Word, Telegram, Outlook, browser, code editor) and press Ctrl+Shift+E - AI rewrites it in place. Fix grammar, translate between languages, paraphrase, formalize tone, or run your own custom prompts. Two AI modes: cloud-based via OpenRouter (one API key gets you GPT, Claude, Gemini, DeepSeek and dozens of other models) or fully local via Ollama - your text never leaves your computer. The core application is open-source under the MIT license. A Pro tier (one-time payment) unlocks usage statistics, settings backup, history export, a model-switch hotkey, and curated prompt packs. Native .NET 8 WPF application - lightweight, no Electron. Available in English, Ukrainian, and Russian.
