Free for Windows and Mac · public beta

Read your script. Keep eye contact.

A see-through teleprompter that sits right under your webcam, follows your voice word by word, and stays off the screen share. Now with a meeting copilot that hears the call and tells you what to say.

No account. No subscription. Works offline.

Built for the moment you hit record

Everything other prompters get wrong, fixed in one small app that stays out of your way.

Follows your voice

Scrolls with your words, not a timer. Pause, ad-lib, go back. It keeps your place with about 20 ms of processing, entirely offline.

Reads aloud, naturally

Hear your script in a natural neural voice at your pace, with the prompter following each word. Great for learning the rhythm.

Ghost mode

Clicks pass straight through to the app behind. Pick how see-through it is, from 15% to solid, with Ctrl Alt [ ].

Private on screen share

The prompter and every window it opens stay out of Zoom, Teams, Meet, OBS and screenshots on Windows. On macOS 15+ it tells you the truth: share a window, not your whole screen.

Phone remote

Scan a QR code and your phone becomes the remote: play, speed, sections, ghost level, new scripts, and a live view of your screen. PIN protected.

Rehearsal coach

After each practice run you get your pace, filler words, long pauses, skipped lines and a score you can watch improve.

Meeting copilot New

Transcribes both sides of a call offline, tells you what to say with Ctrl Alt Enter, answers questions as they're asked, and writes your notes and follow-up email.

AI assistant

Ask anything and get a straight answer. Works with Claude, ChatGPT, Gemini, Grok and more. It can look at your screen and send its answer to the prompter. Press A, or use your phone.

Your screen on your phone New

See your computer's screen live on your phone, about every 1.5 seconds. Pinch to zoom, pause, or save a full-size copy.

One-key screenshots New

Press S to save a full-resolution screenshot to Pictures and copy it. The prompter never appears in it.

See through it. Click through it.

Ghost mode turns the panel see-through while the words stay sharp, so your slides, notes or code stay readable and clickable underneath.

  • Your level. 15% to 100%, set from the keyboard, Settings or your phone.
  • Always legible. A soft outline and a quiet shadow behind the reading line keep the text readable over anything.
  • Out of the way. The controls hide while you read and come back when you hover.

A copilot for every call

Start a meeting and Glass Prompter listens with you. When you need help, press one key. Nobody else on the call can see it.

  • Hears both sides. Your microphone is You, the call's sound is Them. Speech is recognized offline on your computer; audio never leaves it.
  • Assist from any app. Ctrl Alt Enter reads the conversation and your screen and tells you what to say next.
  • Quick actions. What to say, Follow-ups, Recap, Fact-check and Explain, one tap each.
  • Smart answers. When someone asks you a question, a suggested answer appears on its own.
  • Your context. Pick a mode (sales, presentation Q&A, support, negotiation, lecture) or write your own, and add your notes and files. The AI sticks to them.
  • Notes when you hang up. Summary, decisions, action items and a follow-up email, saved in a searchable meeting history.
  • In the AI assistant and on your phone too. The assistant can listen and suggest answers and questions, and the phone remote can start a meeting and press Assist.

Let people know you're taking notes: some places require everyone's consent to record or transcribe a call.

An AI that sees what you see

Stuck on a slide, an error or a question mid-call? Ask. The AI of your choice looks at your screen and your script, and answers in seconds.

  • Answers anything. Work, study, code, numbers, writing, the news. It searches the web when the answer depends on recent facts.
  • Sees your screen. Keep Include my screen ticked and it reads what's in front of you. Glass Prompter's own windows never appear in that picture.
  • Straight to the prompter. Tap Send to prompter and read the answer out, word for word.
  • On your PC or your phone. Press A on the prompter, or open the AI tab on the phone remote.
  • Any AI you like. Paste a key from Anthropic, OpenAI, Google, xAI, DeepSeek, Mistral, Groq, Perplexity or OpenRouter, or run a free model locally with Ollama. The newest model is picked for you.
  • Your key, your data. The key stays on your computer, never reaches the phone, and nothing is sent until you press Send.

Questions

Windows says "Windows protected your PC". Is it safe?

The installer isn't code-signed yet, so SmartScreen shows a warning for new apps. Click More info, then Run anyway. Every download has a published SHA-256 fingerprint, and the in-app updater checks it automatically.

My Mac says the app can't be opened.

The first time, right-click Glass Prompter in Applications and choose Open. On macOS 15 or later, open System Settings, go to Privacy & Security, and click Open Anyway. You only do this once.

Can people on the call see the prompter?

On Windows 10 (2004+) and 11, the prompter and every window Glass Prompter opens (settings, the AI assistant, menus, message boxes, even the file picker) are excluded from screen sharing, recordings and screenshots. macOS 15 and later lets screen recorders capture every window, so on a Mac share a single window or app instead of the whole screen. The badge on the prompter always shows the real state.

Does the meeting copilot record my calls?

No recording is kept. The copilot turns speech into text on your computer as it happens, and saves only that text, the notes and the follow-up email in your local meeting history (which you can search, export or delete). The AI sees the transcript only when you press an action, or when Smart answers spots a question someone asked you. Check your workplace's rules and tell people you're taking notes; some places require everyone's consent.

Does my voice or script go anywhere?

No. Voice recognition and the read-aloud voice run on your computer. Scripts live in a local library. The only internet requests are a once-a-day check for a new version on GitHub (you can turn it off) and, only if you set up the AI assistant, the messages you choose to send to the AI provider you picked.

How do I turn on the AI assistant, and what does it cost?

Glass Prompter itself stays free. The AI runs on your own account with an AI company, which bills you per question (usually a few cents or less). An API key is just a password that lets Glass Prompter use that account. Setup takes about two minutes:

  1. Pick a provider and open its key page: Anthropic (Claude), OpenAI (ChatGPT), Google (Gemini), xAI (Grok), or OpenRouter (one key for hundreds of models).
  2. Sign in, add a payment method or credits if asked (a $5 top-up lasts most people a long time), and click Create key.
  3. Copy the key. It's a long line that starts with something like sk- or AIza.
  4. In Glass Prompter open Settings › AI assistant and paste it. The provider is detected, the key is tested straight away, and the newest model is picked for you.
  5. Press A and ask anything.

Prefer free and fully offline? Install Ollama, choose Ollama as the provider, and no key is needed. Your key stays on your computer and is never sent to the phone. Never share it or paste it into a bug report.

What does the AI see?

Only what you send. When Include my screen is ticked, it gets one screenshot with your question; untick it to send text only. Glass Prompter's own windows are never in that screenshot. It also sees the script on your prompter so it can help with it. Close anything private, like passwords, before asking about your screen.

Found a bug or have an idea?

Glass Prompter is in public beta, so feedback shapes what comes next. In the app, open the menu and choose Report a problem or Suggest a feature; it opens a GitHub form with your app version and system already filled in (nothing personal). You can also open one here. Found a security problem? Please report it privately.

Is it really free?

Yes. No account, no trial, no watermark. It's also open source under the MIT License, so you can read every line of code.
