About the startup

CapyBro is a fast, native Windows productivity tool that seamlessly integrates Artificial Intelligence into your daily workflow. Unlike browser extensions, CapyBro works globally across your entire OS — whether you are typing an email in Outlook, writing code in VS Code, or chatting in Telegram. Key features: — Global Integration: Process any highlighted text via system-wide hotkeys. Defaults: Ctrl+Shift+E (improve), Ctrl+Shift+Q (prompt menu), Ctrl+Shift+Z (undo). — Model Flexibility: Connect to leading cloud models (GPT, Claude, Gemini, and dozens more) via OpenRouter, or run completely offline using Ollama. — Custom Prompts: Create tailored commands (e.g., "Fix Grammar", "Make Professional", "Summarize") with optional dedicated hotkeys. — Privacy First: API keys are encrypted via Windows Credential Manager (DPAPI). History stays on your machine. Using Ollama guarantees no data ever leaves your device. — Native Performance: Built with .NET 8 + WPF + Win32 P/Invoke. 49 MB installer, ~80 MB RAM at idle — five times lighter than typical Electron alternatives. — Open Source: Released under the MIT license. Full codebase available on GitHub for inspection and contribution. Free version is feature-complete for everyday use. Pro ($19 one-time, never subscription) adds usage statistics, history export to CSV/JSON, switch-model hotkey, and premium prompt packs.
