The overlay

A window only you can see

You are showing your software on a call. The client asks something you did not prepare for. GhostCue has heard the question, and one sentence to say, with the points behind it, is already on your screen. Nobody else can see it: the window is left out of every screen share, recording and screenshot by Windows itself.

Which is also why this is a drawing: a screenshot of the overlay comes out without it.

CLIENT What would fifty drivers cost us on the annual plan?

On the annual plan it comes to 510 dollars a month for fifty drivers, billed as 6,120 for the year.

The pricing page lists 12 dollars per driver per month

Annual billing takes 15 percent off, which the same page shows

Not in brief: whether a fleet this size gets a volume discount

  1. State. Listening, starting, off, or an error, which then fills the window with what went wrong.
  2. What it is doing. The devices it listens to, or "Thinking…", "Reading the window…" while an answer is on its way.
  3. The capture check. Says the window is hidden from screen shares, and turns into a red VISIBLE TO SCREEN SHARE if Windows would not hide it.
  4. Buttons. The same as the hotkeys. Clicking them never takes the keyboard from the app you are demoing; history lists the call's earlier answers.
  5. The question it is answering. ASKED in place of CLIENT is the question as the assistant understood it, on Urdu calls.
  6. What to say, in your own voice, ready to read out.
  7. The points behind it: facts, figures and where they came from.
  8. Not in brief: your material did not cover this, so the sentence above is a holding answer, not a promise.
  9. What it heard last, or here, the window you captured with Ctrl+Alt+W, and whether the whole page came with it.
  10. The hotkeys, all with Ctrl+Alt, so you never have to reach for the overlay mid-call.
  11. Drag anywhere to move it; drag this corner to resize. Size, position, text size and opacity are kept.
For live calls

The assistant

Listens to the call and tells you what to say when the client asks a question, drawing on your brief and your own documents.

 For recorded demos

The teleprompter

Walks you through a timed script while you record a demo video: what to show, what to do, and the words to say.
The assistant

From the client's question to your answer in seconds

An answer starts to appear about two to four seconds after the client stops speaking: the question, one sentence to say, and up to three supporting points.

  1. ContextWrite the brief: what you are showing, who the client is, what they care about, and what you must not promise.
  2. KnowledgeAdd FAQs, pricing or specification files for the answers to draw on, and a project folder to dig into.
  3. AudioPlay a sound and speak, and check that both level bars move.
  4. Start listeningPress it before the call. The first start takes about ten seconds while Claude Code starts.

Answer from what is on screen

Asked about a web page, an email or what the client is showing you? Press Ctrl+Alt+W on that window. A page in your browser goes with its whole text, scrolled or not; anything else, such as the client's shared screen, goes as a screenshot, so the answer knows what you can see and no more.

Answers that know their limits

A point marked Not in brief: means your material did not cover the question, and the sentence above it is a holding answer rather than a fact.

As long as you need

Answer length runs from one sentence to a full explanation. A question about a set of things gets every member, and a request for code gets the code.

Look back through the call

Every answer stays until the next call. Step back with Ctrl+Alt+, or open the history and pick a question. A new answer waits for you instead of pushing away the one you are reading.

Urdu and English

For Urdu-speaking clients, answers come in the client's language, with Urdu in Roman letters. The overlay shows the question as it was understood, so you can tell when it misheard.

How it works

On your computer, with your own Claude

Both sides of the call

The client is whatever your speakers or headphones play, captured with WASAPI loopback. You are the microphone. Wear headphones: GhostCue drops microphone speech that overlaps the client's.

Transcribed locally

Speech is turned into text on this computer with faster-whisper. In English the base model takes about 0.7 seconds a sentence on a six-core CPU.

Answered by your Claude Code

Answers come from your own Claude Code, kept running for the length of the call so each answer starts in under a second. The transcript, and any window you capture, is sent to Anthropic to be answered and counts towards your plan's usage.

Kept to yourself

Settings and call transcripts stay in %APPDATA%\GhostCue, and transcripts can be turned off. No Claude Code session is saved.

The teleprompter

Record a demo without losing your place

Write the demo as a plain-text script of timed cues. The overlay shows each cue's directions on the left and the words to say on the right, and moves on by the clock or when you press a key.

[0:12] Sign in
DO: Type the email and password, then click "Sign in".
SHOW: The dashboard, with the three summary cards.
SAY:
  I'll start by signing in with a demo account.
  This is the dashboard.
NOTE: If the login is slow, keep talking.
Spacestart or pause the clock
XZnext or previous cue
Rrestart from the first cue
Mauto or manual advance
↑↓bigger or smaller text
Hhide or show

In manual mode, cues change only when you press Next or Previous, and the countdown turns red when you fall behind the script. The teleprompter uses only the Python standard library.

Install

Get started

Needs 64-bit Windows 10 version 2004 or later and, for the assistant, Claude Code, installed and signed in.

Download for Windows The installer needs no administrator rights. A zip that runs without installing is on the same page.

GhostCue is not code-signed yet, so Windows SmartScreen says "Windows protected your PC". Click More info, then Run anyway. The speech model downloads once, the first time you start listening.

Or run it from source, with Python 3.10 or later

# get the code
git clone https://github.com/Blankscreen-exe/ghostcue.git
cd ghostcue

# install
python -m venv .venv
.venv\Scripts\python -m pip install -r requirements.txt

# run: the assistant lives in the system tray
GhostCue.bat

The teleprompter is on the tray menu and in the Start menu, or run python -m ghostcue prompter my_script.txt.
