CapyBro: AI text rewriter for Windows on a single global hotkey

Hey Product Hunt 👋 I'm Roman, solo dev from Ukraine, and CapyBro is what I've been building for the past 4 months of nights and weekends. The story: I was Alt+Tab-ing to ChatGPT 30+ times a day for tiny text fixes — one comma in a Slack message, a paragraph translation, a passive-aggressive DM rewrite. AI was trapped in a browser tab while every other Windows utility lives one hotkey away. So I built it. What CapyBro does: Select text anywhere on Windows → press Ctrl+Shift+E → AI rewrites it in place. Word, Telegram, VS Code, your browser, Notepad — anywhere. Two backends: ☁️ Cloud via OpenRouter (one API key gets you GPT, Claude, Gemini, ~300 models) 🔒 Local via Ollama (text never leaves your machine — true privacy) Tech choices: • Native .NET 8 + WPF (not Electron) — 49 MB installer, <1s cold start • MIT-licensed core. The Pro features (curated Prompt Packs, settings backup, usage stats) are $19 one-time. Never subscription. I hate productivity-tool subscriptions. What I'd love feedback on: 1. Is the workflow obvious from the homepage? 2. What prompts would you add to the built-in library? 3. Mac users: Avalonia port is ~2 months out. Would you use it?
