Frequently Asked Questions

Frequently asked questions

Everything you need to know about Relay's architecture, privacy, and models.

Relay is built natively in .NET 10 with Win32 interop rather than heavy Electron wrappers. It registers a global hotkey (Ctrl + Space) to freeze any multi-display setup in under 10ms, captures active process metadata, extracts text offline with Windows.Media.Ocr, and streams Gemini vision responses directly into a glassmorphic floating panel.
Relay processes screen snapshots strictly in-memory—images are never persisted to disk. API keys are encrypted at rest via Windows DPAPI, and an automatic process blacklist prevents accidental capture of password managers like 1Password, Bitwarden, or KeePass.
Relay supports Windows 10 (Version 19041+) and Windows 11 on x64 and ARM64 architectures. It includes native Per-Monitor V2 DPI scaling normalization across mixed-DPI multi-monitor configurations.
Yes. You can supply your own Google Gemini Flash-Lite API key or configure a local Ollama multimodal endpoint directly in Settings for 100% offline desktop intelligence.
The RelaySetup.exe installer installs cleanly into %LocalAppData% without requiring Administrator or UAC elevation. It starts minimized in the system tray on boot, idling at just ~10–15 MB RAM with 0% CPU consumption.
