Captain for Mac New in 0.8.8

Hold fn. Say what you need.

In Mail, a PDF, a spreadsheet, a terminal, anywhere. Captain reads what's on screen, takes your selection as what you mean, and sends it with what you type or say to the agent that knows the work. The answer comes back in a panel beside you, and Paste into Mail puts it where you were.

A menu-bar app for macOS 14 and later, Apple silicon and Intel. It talks to your own Flight Deck.

Captain's panel over Mail: the reply to Harbour Logistics, chips for the selection, the screen text and what's under the pointer, and the task: Yes to both, telematics from the month they join, friendly and short

One key, wherever you are.

  1. 1

    Hold fn

    Alone, for 3 seconds. A ring fills by the pointer. Any other key cancels it, so fn shortcuts keep working. Or click the menu-bar icon, or a floating button.

  2. 2

    It reads

    The app you were in stays the active one. The panel shows what Captain read, as chips you can switch off or look at.

  3. 3

    Say it, or type it

    The mic, or have it listen as it opens. A pause ends it, or letting go of the key. Left empty, the agent decides what's useful.

  4. 4

    The answer

    Its steps and the answer as it's written. Copy it, paste it back where you were, or ask a follow-up.

The key, the hold time (half a second to five) and the voice are in Settings. One-click actions: Explain, Summarize, Draft a reply, Improve, Translate, What's wrong?, Make tasks, Remember, Save it.

What it reads Through Accessibility

Your selection first. The rest is context.

  • The selection, sent first as the part you mean, so "explain this" means the clause you highlighted.
  • What's under the pointer, and the line around it: point at the figure you're asking about.
  • The window's text: what's on screen first, the rest of the document after. It works in Chrome and Electron apps too, and in a terminal it keeps the end of the scrollback.
  • A screenshot of the window or the whole screen, if you turn it on, and text read off the screen on the Mac itself (OCR) when an app shares none.

It lands in your vfs:screen-clips/ shared folder and in the agent's chat, as your words. The capture is marked as screen content, never your instructions.

Captain's panel over a policy wording PDF in Preview: chips for the selection, 47,000 characters of screen text, the pointer on clause 4.3 Unattended vehicle, and a screenshot

The answer, back where you were.

A draft for the email you were answering, pasted into your reply. The clause you selected, in plain words, with what to watch for. Ask a follow-up about the same capture, or press fn again for a new one.

Install it in a minute.

Download it from GitHub or from your deck's Connections → Browser. It needs a Flight Deck on 0.8.8 or later.

  1. 1

    Download

    Captain for Mac 0.1.1 (.zip, 2 MB, from the GitHub release), or Connections → Browser → Download Captain for Mac. Unzip it and move it to Applications.

  2. 2

    Open Anyway

    It isn't notarized yet. If macOS won't open it, go to System Settings → Privacy & Security and press Open Anyway.

  3. 3

    Allow Accessibility

    That's the one it needs. Screen Recording, the microphone and speech recognition only for the screenshot, OCR and voice.

  4. 4

    Connect

    Type your deck's address in its Settings and approve the code in Flight Deck. The token sits in your Keychain; disconnect it any time.

Where your words go: speech is Apple's recognition, on the Mac when you tick Only on this Mac and the language allows it. What Captain read goes to your own deck and agent, nowhere else, and only when you send it. Each piece is a chip you can leave out.
