CapyBro

CapyBro brings AI to your everyday text without switching to a browser tab. Select text in any Windows app — Word, Outlook, a browser field, VS Code, Telegram — press a global hotkey (Ctrl+Shift+E), and AI rewrites, fixes grammar, translates, or paraphrases it in place.

Two backends: **OpenRouter** (cloud — GPT-4o, Claude, Gemini, DeepSeek, your own key) or **Ollama** (fully local/offline — text never leaves the machine).

Native .NET 8 / WPF, ~48 MB, no Electron, zero telemetry. Unlimited custom prompts with per-prompt models, diff preview, history. UI in English, Ukrainian, Russian.

Free and open-source core (MIT). Optional one-time $19 Pro (never a subscription) for prompt packs, history export, settings backup and usage stats. Windows 10/11 x64.
