Quick Send
Send anything to Nebula from any app with one keyboard shortcut. Attach a screenshot of what you are looking at and let Nebula pick the right agent.
Quick Send puts a Nebula composer over whatever you're doing. Press ⌘ ` (Mac) or Ctrl ` (Windows / Linux), type, and send — without leaving the app you're in.
The Capsule expands into the composer and flies back to its corner when you send, so you land back where you started.
What would you like to do?
What happens when you send
Each send starts a fresh conversation. You don't pick an agent — Nebula reads what you sent and routes it to whoever should handle it, exactly like sending from Home.
The Capsule shows the send going out, then picks up the run and reports back when there's something to see. You can carry on with what you were doing.
What you can set on the way out
The composer carries a short row of controls.
Attaches a screenshot of the screen you're pointing at, so you can ask about what's in front of you without describing it. The shot is taken after the composer gets out of the way, so you capture your work rather than the Nebula window. It only appears when you've given Nebula access to your computer.
Whether the new thread is visible to your workspace or just to you. It remembers what you last chose.
Sends this one on the Nebula Max tier. See Model.
The shield toggles your approval gate for writes and deletes. It's the same account setting as in the web app, so changing it here changes it everywhere. See Approvals.
The paperclip attaches files — up to 8 at a time. Images preview as thumbnails. Uploading starts the moment you attach, and sending no longer waits for it to finish: the composer folds away immediately and the upload rides along in the background, so a big file doesn't hold you hostage. The Capsule card narrates Uploading… then Sending… so you can watch it land.
Screen aware is the reason to reach for Quick Send over a browser tab. Stuck on an error dialog, a chart, or a diff, hit the shortcut and ask "what am I looking at?" without switching windows or taking a screenshot yourself.
Screen aware is one screenshot, not live
Despite the name, Screen aware isn't continuous — it takes a single still image at the moment you send, attaches it to that message, and stops there. Your agent sees what your screen looked like then, not what it looks like now.
When you want an agent watching something that changes — stepping through a bug, walking a dashboard, reviewing a document together — share your screen on a call instead. There the agent can take a fresh look every time you ask.
Screen capture permission
The first time you use Screen aware on a Mac, macOS asks whether Nebula can record your screen. It's the standard system prompt, and you can change your mind later in System Settings → Privacy & Security → Screen Recording.
Nothing is captured unless Screen aware is switched on for that send. If a capture fails, your message still goes — it just goes without the picture.
Changing the shortcut
Both desktop shortcuts are re-recordable in Settings → Shortcuts in the desktop app. If another app already owns the combination you pick, Nebula keeps your previous one rather than silently doing nothing.
You can also reach Quick Send from the tray menu.
