Platform features across every workspace
Beyond the seven sidebar panes, Nucleus layers sync, alerts, AI, news, and macOS-native polish so the app stays useful whether you are in mail, music, or a tmux session.
☁️
Nucleus Cloud & iCloud sync
Sync notes, bills, dashboard analysis, and settings through Nucleus Cloud. iCloud CloudKit keeps notes and bills on your Apple devices — with manual sync and status on the Dashboard.
🔔
Smart notifications
Per-message email alerts with sender and subject, bill due reminders, breaking news banners, and clipboard password prompts — with per-account Funky, Nucleus Mail, or system sounds.
🚨
Breaking news alerts
Urgent headlines slide in as a macOS-style top banner from any workspace — with Open story, auto-dismiss, and mood-aware news cards on the Dashboard.
📬
Incoming mail overlays
New mail while you are on Dashboard, Notes, Music, or Terminal shows the same modal overlay — preview the sender and jump to Inbox without losing your place.
🤖
Nucleus AI
Optional Dashboard panel for AI-assisted answers — collapsible with settings toggles, slow auto-scroll for long responses, and IPv4 fallback when local DNS misbehaves.
📰
News feed
Headlines from your location and holiday countries, with mood-aware color coding, plain-language In brief summaries, and short notes on why each story feels urgent, concerning, or positive.
📎
Menu bar companion
Optional menu bar item for recent clips and passwords, password-save prompts, and clipboard access without bringing the main window forward.
↕️
Reorderable sidebar
Drag workspace items to match your daily flow — like DiskWise. Compact sidebar mode saves horizontal space; badges show unread mail, bills, notes, tmux sessions, and now playing.
🪟
Window layout memory
Nucleus remembers window size, position, and which monitor you used — including external displays — across relaunch and app switches.
🔒
Isolated Google sessions
Each Gmail account gets its own WKWebView cookie jar on your Mac. Web sessions stay local; external links open in your default browser.
⬆️
Sparkle auto-updates
Signed and notarized releases with in-app Check for Updates. What's New appears after each upgrade with highlights from the release notes.
🍎
Native macOS polish
SwiftUI shell with dock badges, hourly beep, refreshed Nucleus app icon, five-minute idle return to Dashboard (except Notes, Music, and Terminal), and Accessibility-aware clipboard hotkeys.
