What is CapyBro?

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.

CapyBro supports two AI modes: cloud-based via OpenRouter (one API key gets you GPT, Claude, Gemini, DeepSeek, and dozens of other models) and fully local via Ollama (your text never leaves your computer — true privacy). The core application is open-source under MIT license. A Pro tier ($19, one-time payment, never subscription) unlocks usage statistics, settings backup, and curated prompt packs for legal, marketing, and development workflows.

Native .NET 8 + WPF application — lightweight, fast cold start, no Electron overhead. Available in English, Ukrainian, and Russian.
