What I built:
ZupFlash — an AI desktop agent for Windows. Press Alt + Space anywhere and an AI overlay appears on top of your current app. It can read your clipboard, paste into any window, open apps, capture screenshots, read/save files — 9 agent tools total. Your API keys, your models. No accounts, no subscriptions.
How Cursor helped:
Everything — the app, the website, and all agent tools were built entirely with Cursor. The stack is Tauri v2 + React frontend + Rust backend with a custom agent loop, tool registry, consent flow, and provider integrations (OpenAI, Claude, Gemini, Grok, Mistral, Ollama, LM Studio). Cursor handled the Rust agent system, Windows API integrations, multi-provider streaming, and the full Next.js marketing website.
Wouldn’t have shipped this fast without it.
