How is LucidArc different from the Windows Start Menu or PowerToys Run?

While the Start Menu and PowerToys Run are great for basic launching and searching, LucidArc goes much further. Our key differentiators are deep AI integration, powerful workflow automation, smart clipboard history, Web Mode access, Instant feature integration, and a highly polished, customizable user experience designed for speed. We’re not just a launcher; we’re an AI-powered command center.

What are the system requirements?

LucidArc is built for modern systems and runs on Windows 10 (version 2004 or newer) and Windows 11. It’s highly optimized for performance and uses minimal system resources in the background.

How does the AI integration work? Do you use my data?

Your privacy is our top priority. AI features are only activated when you explicitly request them through a specific command or prompt. We use LucidQuery’s AI models with zero-access architecture: all communication is end-to-end encrypted, we maintain no logs of your LucidArc usage, and your data is never stored or used for training. For features like file search, all processing happens locally on your machine. AI only runs when you ask it to, not in the background.

Can I cancel my Pro subscription anytime?

Yes! You can cancel your Pro subscription at any time. If you cancel, you’ll continue to have Pro access until the end of your billing period, then automatically switch back to the free plan. Your data and settings are always preserved.
