Thin client of the hosted InferenceHub chat (chat.inferencehub.tech). Unsigned builds — expect an OS trust warning on first run. macOS (Apple Silicon, ad-hoc signed, not notarized) Drag InferenceHub.app out of the dmg into /Applications, then clear the quarantine flag: xattr -dr com.apple.quarantine /Applications/InferenceHub.app (or right-click → Open → Open Anyway on macOS 15+.) A fully signed + notarized build (no workaround) is still pending an Apple Developer cert. System-wide shortcuts (they work while another app has focus): Ctrl+Shift+Z toggles click-through (clicks pass to the window underneath), Ctrl+Shift+↑ / ↓ raise/lower window opacity, Ctrl+T starts/stops meeting-audio transcription. Updating from an earlier version? macOS silently drops the app's Screen & System Audio Recording approval on every update (unsigned builds can't keep it), even though System Settings still shows it allowed. If meeting-audio transcription complains: System Settings → Privacy & Security → Screen & System Audio Recording → switch InferenceHub off and on, then quit and reopen the app. Windows (x64, NSIS installer, unsigned) Run InferenceHub__x64-setup.exe. SmartScreen will show "Windows protected your PC" — click More info → Run anyway. If the WebView2 Runtime is missing (rare), the installer downloads it automatically. The Windows build is chat + sign-in + tray only (no live transcription / Stealth Mode / window opacity / overlay hotkeys — those are macOS-only for now). A code-signed build (no SmartScreen warning) is pending an Authenticode / Azure Trusted Signing cert.
