Why Look for Cluely Alternatives?

What to look for in a Cluely alternative
Cluely popularised the idea of an invisible AI overlay, but its $20/month price, Electron footprint, and online-only design push many people to look elsewhere. When you compare alternatives, weigh four things: stealth (does it show up in screen share or recordings), footprint and speed, offline capability, and price.
Ofradr was built specifically to win on those axes — native C++ stealth, ~800KB size, local-model support, and a free Community Edition.
- Stealth: native overlay vs. a visible window or browser tab
- Footprint: ~800KB native vs. 50MB+ Electron apps
- Offline: local models vs. cloud-only assistants
- Price: free Community Edition vs. monthly subscriptions
How the main options compare
Cluely is polished but expensive and online-only. Interview Coder focuses on coding interviews at $19/month. Generic AI tools like ChatGPT aren't invisible at all on a screen share. Ofradr is the option that combines genuine system-level stealth with a free tier and offline support.
Frequently Asked Questions
What is the best free Cluely alternative?
Ofradr is the best free Cluely alternative. It offers a native, system-level invisible overlay, offline AI support, and a free Community Edition, where Cluely costs around $20/month.
Is Ofradr more stealthy than Cluely?
Yes. Ofradr uses a native C++ overlay rendered at the compositor level, so it stays out of screen shares and recordings, while Electron-based tools are easier to detect as visible windows or processes.
Can these tools be detected on Zoom or proctoring software?
Ofradr's native overlay is not captured by Zoom, Teams, or proctoring screen recording. Browser- or window-based assistants are far easier to detect.
