Glass Prompter
A see-through teleprompter that sits right under your webcam.
It follows your voice word by word, reads your script aloud, and stays off the screen share.
New in 2.7: a meeting copilot that transcribes both sides of a call, tells you what to say (Ctrl+Alt+Enter from any app) and writes your notes and follow-up email, all invisible on screen share. Plus the 2.6 AI assistant that works with any AI provider and can see your screen.
Free and open source (MIT) for Windows and Mac. Public beta: feedback is very welcome.

Install
The quickest way is the website. It detects your computer and gives you the right download button.
Not sure which Mac you have? Open the Apple menu › About This Mac. If it says Chip: Apple M…, you have Apple silicon. If it says Processor: Intel, you have an Intel Mac.
Windows
- Download
GlassPrompter-Setup-x.y.z.exe from the website.
- Double-click it. It installs just for you, so no admin password is needed.
- If you see "Windows protected your PC", click More info, then Run anyway. The app isn't code-signed yet, which is why Windows shows this warning for new apps.
- Glass Prompter opens and appears in your Start menu. Choose Start at login in Settings if you want it to open with Windows.
With winget, which comes built into Windows 11. Open Terminal and run:
winget install TokunboAjayi.GlassPrompter
winget will work once Microsoft approves the listing (pull request). Until then, use the installer.
Mac
- Download the .dmg for your chip from the website.
- Open it and drag Glass Prompter into Applications.
- The first time only: right-click Glass Prompter in Applications and choose Open, then Open again.
On macOS 15 or later, open System Settings › Privacy & Security, scroll down, and click Open Anyway.
(This is needed because the app isn't notarized by Apple yet.)
- Click Allow when it asks for the microphone, so Voice Follow can hear you.
With Homebrew. Open Terminal and run:
brew install --cask tokunboajayi/tap/glass-prompter
Linux (from source)
Linux works, but some features aren't available there: there's no screen-share hiding and no global shortcuts. You need Python 3.10 or newer.
git clone https://github.com/tokunboajayi/glass-prompter.git
cd glass-prompter
python3 -m pip install -r requirements.txt
python3 glass_prompter.pyw
For Voice Follow you also need the free offline speech model. CONTRIBUTING.md explains where to put it.
First five minutes
- Place it. Drag the prompter right under your webcam, so your eyes stay near the lens while you read. Drag its edges to resize it.
- Add a script. Click the Scripts button (or press E), then paste text or import a
.docx, .md or .txt file. You can also drop files into the Documents/Glass Prompter folder.
- Read. Press Space to scroll at your chosen pace. Use ↑ and ↓ to go faster or slower.
- Or let it follow your voice. Press V, then Space, and start talking. The text scrolls as you speak, and it runs entirely offline.
- Check the privacy badge in the bottom-left corner before a call.
- Green "Private": viewers can't see the prompter on screen share.
- On macOS 15+: share a single window, not your entire screen.
Script tips:
| Write this on its own line | What it does |
|---|
# Opening | A section. Jump between sections with PgUp/PgDn or from your phone. |
[PAUSE] | Scrolling stops here until you press play. |
[SMILE], [SHOW SLIDE 3] | A cue for you, shown in amber. It's never read out. |
Everything else is one click away in the ⋯ menu: text size, mirror text, ghost mode, phone remote and settings.

Phone remote
Control the prompter from across the room. You don't need to install an app on your phone.
- On your computer, open ⋯ › Phone remote.
- Scan the QR code with your phone's camera. Your phone and computer must be on the same Wi-Fi.
- Enter the 6-digit PIN shown on your computer.
From the phone you can:
- play, change speed and jump between sections;
- set the ghost level and start Read Aloud;
- type or upload new scripts;
- see your computer's screen live (Screen tab);
- chat with an AI that can see your screen and script (AI tab).
It works over your Wi-Fi only and never goes through the internet. On Windows, click Allow on the firewall prompt the first time.
Screen view and AI assistant
-
Screen tab: your computer's screen, refreshed about every 1.5 seconds. Tap it for full size and pinch to zoom. On Windows the prompter never appears in it. On a Mac, allow Glass Prompter under System Settings › Privacy & Security › Screen Recording. Turn it off in Settings › Privacy › Phone can view my screen.
-
AI assistant on the computer: press A on the prompter or choose ⋯ › AI assistant. Same chat, on your PC. Turn on Listen to meeting and it follows the call through the meeting copilot (offline transcription; the meeting, notes and follow-up email are saved to Meeting history when you stop). With Smart answers on, it offers an answer when someone asks you a question, and questions you could ask after they've talked for a while. Assist and the copilot's quick actions appear above the chat while you listen.
-
Screenshots: press S on the prompter, or tap Save screenshot on the phone's Screen tab.
-
AI tab: a chat with Claude that answers any question. It can look at your current screen, search the web and read the script on the prompter. Ask "what should I say about this slide?" or "tighten my intro", then tap Send to prompter to read the answer.
Quickest: sign in, no key. In Settings › AI assistant › Sign in:
- ChatGPT uses your ChatGPT Plus or Pro plan. Answers count toward your plan's usage instead of an API bill. You can cap how much Glass Prompter may use, or disconnect it, in ChatGPT Settings. (OpenAI offers this to open-source apps that run locally.)
- OpenRouter signs you in and creates a key automatically: one key for Claude, GPT, Gemini and hundreds more, on pay-as-you-go credit.
Or use an API key:
- Get an API key from any AI provider: Anthropic (Claude), OpenAI (ChatGPT), Google (Gemini), xAI (Grok), DeepSeek, Mistral, Groq, Perplexity, Together, or OpenRouter (hundreds of models with one key). Or run a free model on your own computer with .
Meeting copilot
Live help during calls, in a window nobody else can see on screen share. Open it with K on the prompter,
⋯ › Meeting copilot, or Ctrl+Alt+M from any app.
- Press Start meeting. Your microphone is transcribed as You and the computer's sound (Zoom, Teams, Meet...)
as Them. Recognition runs offline on your computer.
- Whenever you need help, press Assist or Ctrl+Alt+Enter from any app. The AI
reads the conversation (and your screen, if you allow it) and tells you what to say.
- Or use a quick action: What should I say?, Follow-up questions, Recap, Fact-check, Explain.
With Smart answers on, a suggestion appears by itself when someone asks you a question.
- Press End meeting. You get a summary, decisions, action items and a follow-up email, saved in
Meeting history (search, export to Markdown, copy the email).
Context: pick a mode (sales call, presentation Q&A, support, negotiation, lecture, or your own) and add your notes
and files: product sheets, prices, agendas. The AI treats them as the truth and won't make up facts beyond them.
It uses the same AI key as the assistant. The AI only sees the transcript when you press an action or Smart answers
spots a question. Let people know you're taking notes: some places require everyone's consent to record or
transcribe a call. On a Mac only your microphone is heard, unless you route the call through a loopback device
such as BlackHole.
Updates, uninstall and your data
Updates arrive inside the app. Once a day it checks GitHub, and when a new version is out you'll see Update to x.y.z in the tray (Windows) or menu bar (Mac).
- Every download is checked against its published SHA-256 fingerprint before it installs.
- On Windows the update installs and reopens the app on its own.
- On a Mac the new disk image opens, and you drag the app into Applications again.
- You can turn update checks off in Settings › System.
- Package managers:
winget upgrade TokunboAjayi.GlassPrompter or brew upgrade --cask glass-prompter.
Uninstall:
| How |
|---|
| Windows | Settings › Apps › Installed apps › Glass Prompter › Uninstall, or winget uninstall TokunboAjayi.GlassPrompter |
| Mac | Drag the app from Applications to the Trash, or brew uninstall --cask glass-prompter (add --zap to also delete your data) |
Your data stays on your computer: scripts, settings, the daily backups (the last 7 are kept) and logs.
| Folder |
|---|
| Windows | %APPDATA%\GlassPrompter |
| Mac | ~/Library/Application Support/GlassPrompter |
Voice recognition and the read-aloud voice both run on your computer. Audio never leaves it. The only internet requests are the optional daily update check to api.github.com and, if you set up the AI assistant, the messages you send to the AI provider you chose.
Troubleshooting
Check the badge in the bottom-left corner.
- Windows 10 (2004+) and 11: the prompter is hidden from Zoom, Teams, Meet and OBS. If the badge isn't green, press C.
- macOS 15 and later: Apple lets screen recorders capture every window. Share a single window or app, not the entire screen.
- Open Settings › Voice Follow and pick the right microphone.
- On a Mac, check System Settings › Privacy & Security › Microphone and turn Glass Prompter on.
- The live latency shown next to "Listening" should be under about 100 ms.
Another app is probably using the same keys. For example, PowerToys often uses Ctrl+Alt+Space. Glass Prompter falls back to watching the keyboard itself, so the shortcut still works, but it may respond a little later. Free the keys in the other app to fix it fully.
The app isn't code-signed yet. See step 3 of Windows or Mac. You can check any download against the .sha256.txt file next to it on the releases page.
Still stuck? In the app's menu choose Report a problem. It opens a GitHub form with your app version and system already filled in (nothing personal). Or open one here. Logs are under About Glass Prompter › Open logs; check them for anything private before attaching. Security problems: please report privately.
