Press Option+Space in any app and Ghost drops out of the notch. Ask it something and it answers on the model you choose. Ask it to do something and it does: it writes the file, books the meeting, texts your friend or checks on your coding agents.
One keystroke, then Ghost builds a web page, makes a PDF and takes it back, books lunch, sets a reminder, answers from your own files and runs your coding agents.
All of this happens in the same bar under your notch, inside the apps and files you already use.
Run Ghost on your Claude Code, Codex or Antigravity plan, on an API key for Claude, Gemini, DeepSeek or any OpenAI-compatible server, or on a model in LM Studio or Ollama that never leaves your Mac. You switch between them from one menu.
Ask for a PDF, a Word document, a slide deck, a spreadsheet or a web page and Ghost saves it where you ask, such as your Desktop. Every file Ghost makes, moves or edits gets an Undo button, and by default it asks before it changes anything.
Type “lunch with Sam Friday at 1pm” and the event goes into whichever calendar you name, Google calendars included. Reminders and notes work the same way with Undo, and “text mom: running late” finds the right contact and asks before it sends.
Point Ghost at a folder and it builds a search index on your Mac. Each answer names the file and page it used, and one click opens it. Tell it “when I ask about my classes, read timetable.xlsx” and it reads that file every time.
Paste a screenshot with ⌘V, or capture the whole
screen with one button, and ask about it. Drag over any part of
the screen and Ghost reads the text off it in about a tenth of a
second, on your Mac.
Claude Code, Codex, opencode and DeepSeek Harness sessions from any terminal show up in the Agents tab, and when one needs permission it asks you from the notch. You can chat with Claude, Codex or opencode right there, give Claude a subagent on another model, and see what each task cost and which files it changed.
Ghost hangs from the notch, or floats near the bottom of the screen if you prefer. On a monitor without a notch, it draws one.
claude, opencode, vim and ssh run inside Ghost as they would anywhere else, and the notch shows when an agent is working and when it is done.
What came due, what arrived unread and what is coming in the next two days, gathered from Calendar, Reminders, Mail and Messages on your Mac. Add a short news briefing on up to three topics.
Days until the trip, the exam or the launch, taken from Calendar and Reminders, plus any you add yourself.
A pomodoro that runs in the notch and keeps a log of what you studied and for how long.
Say “remember that my flight is Tuesday” and Ghost keeps it in mind for every question after that.
Maths, unit conversions, dates and time zones come back at once, offline, without asking a model.
Check battery health, quit an app, change the brightness, run a Shortcut or get a full system report.
Turn on the web console and use Ghost's chat and terminal from your phone's browser. It only answers on your own network.
Ghost can reach a lot of your Mac, so you decide how much. Your API keys stay in the macOS Keychain, and every release is notarized by Apple.
Web, files, Mac automation, Messages, screen capture and the terminal are six separate switches, and each stays off until you turn it on.
Messages, Notes, Mail and Contacts are only ever read by a model running on your Mac. Ghost refuses to pass them to a cloud one.
Write a boundary once, such as a folder Ghost must never touch, and it is checked before every action. The action log shows what Ghost tried, what you allowed and what it refused.
A native Mac app, notarized by Apple. It stays out of the Dock and out of your way until you call it.
