Nucleus brings Gmail, clipboard intelligence, markdown notes, a password vault, monthly bills, embedded tmux, and Funky alerts together across multiple Google accounts. Open the Dashboard for a morning greeting, Your day clipboard analysis, breaking news, and a clear summary of what needs attention before you dive in. Notes, passwords, and bills sync to iPhone, iPad, and Android through the App Store and APK companion apps — with Nucleus AI and sync via Nucleus Cloud or iCloud.
Native on Mac, iPhone & iPad
Nucleus keeps mail, bills, clipboard, notes, passwords, music, and tmux in one SwiftUI workspace on Mac — with a Dashboard that analyses your day. Notes, passwords, and bills stay with you on iPhone and iPad through the App Store companion.
Six workspaces
Nucleus is organized around native workspace panes — not buried settings menus. Drag sidebar items to match your routine; Settings and Accounts stay fixed at the bottom.
Morning command center
Start every day with a greeting, daily quote, and a read on what needs attention — unread mail, bills, passwords, clipboard patterns, weather, news, and payment prep on one screen.
Multi-account Gmail
Category tabs for Personal, Work, Client, and more — each Google account gets an isolated web session so personal, work, and school inboxes stay separate.
Capture memory
Automatic clipboard history with search, pinning, and quick paste — without leaving the app you are working in.
Knowledge vault
Markdown notes for meeting logs and daily capture, plus a structured password vault with username, email, URL, and password fields.
Monthly cash flow
Track recurring bills in multiple currencies, log full or partial payments, and see what is still due this month.
tmux inside Nucleus
Browse active tmux sessions, attach interactively inside an embedded terminal, and detach without losing running work.
Nucleus Dashboard
The Dashboard greets you with a daily quote, then layers intelligent workspace insight with clipboard-powered productivity analysis. It learns from what you copy throughout the day — not to store secrets, but to reveal patterns: where your attention goes, which apps you bounce between, and what is still sitting unfinished in your clipboard queue.
Clipboard productivity analysis
Every 30 minutes, Nucleus reviews today's clipboard captures and turns them into a personal productivity brief — category breakdown, a plain-language summary, data-driven insights, and concrete suggestions to improve how you work.
Workspace status at a glance
A dated narrative that weaves together unread mail, saved passwords, upcoming bills, and clipboard trends — so you know what needs attention before opening a single tab.
Seven-day clipboard trends
A bar chart breaks the last week of clipboard activity into Development, Communication, Research, Notes & drafts, Admin & text, and Data & numbers — making it easy to spot where your attention actually goes.
Context without clutter
Weather, live CPU and memory for Nucleus, Nucleus Cloud and iCloud sync status, the next public holiday, a scrolling news feed, breaking news banners, optional Nucleus AI panel, summary metrics, and payment preparation — all configurable from Settings → Dashboard.
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.
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.
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.
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.
New mail while you are on Dashboard, Notes, or Terminal shows the same modal overlay — preview the sender and jump to Inbox without losing your place.
Optional Dashboard panel for AI-assisted answers — collapsible with settings toggles, slow auto-scroll for long responses, and IPv4 fallback when local DNS misbehaves.
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.
Optional menu bar item for recent clips and passwords, password-save prompts, and clipboard access without bringing the main window forward.
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.
Nucleus remembers window size, position, and which monitor you used — including external displays — across relaunch and app switches.
Each Gmail account gets its own WKWebView cookie jar on your Mac. Web sessions stay local; external links open in your default browser.
Signed and notarized releases with in-app Check for Updates. What's New appears after each upgrade with highlights from the release notes.
SwiftUI shell with dock badges, hourly beep, refreshed Nucleus app icon, five-minute idle return to Dashboard (except Notes and Terminal), and Accessibility-aware clipboard hotkeys.
Nucleus is built in Swift with modular kits for mail, clipboard, notes, bills, and sync. Contributions and issue reports are welcome on GitHub.
