AI Meeting Assistant Copilot

An open-source AI meeting assistant for Zoom, Google Meet and Teams. It listens to the call and writes what to say back on a private overlay that screen sharing does not show. Runs on the Claude or ChatGPT subscription you already have.

What is this?

A client asks you something on a call. You know the answer, but turning it into clear words while they wait is the hard part, especially in a second language.

Meeting Copilot listens to the call and shows you what to say back, a few seconds after they finish speaking. You read it, say it in your own voice, and keep the conversation moving. It is a free, open-source alternative to paid AI meeting copilots such as Cluely, built for client calls, sales calls and consultations.

Features

📝 Before the call

• Meeting brief. Who you are meeting, your role, your goal, and any material the answers can use: pitch, prices, past results, your CV.
• Your own script. Write the exact lines you want to say. When a question is covered, you get your line back, almost word for word.
• "Ask the AI what else it needs." It asks the 4 to 6 questions whose answers improve the live answers most.
• Better spelling of your words. Names and jargon from the brief are taught to the speech recogniser, so "idempotency" does not come out as "eye-dampitancy".

🎧 During the call

• Live answers. Written in the first person, ready to say. With Claude the words appear as they are written.
• Answers them, never you. Their voice comes from your speakers and yours from your microphone, so the two are never mixed up.
• No invented facts. If the brief does not cover a question, it answers only from your facts and will not make up experience, results or prices.
• Questions to ask next. Three short suggestions that move the meeting toward your goal.
• Ask box. Type anything mid-call: "how do I say no politely?"

🔒 Private by design

• Hidden from screen sharing. Share a window or a tab and the overlay is not in what the other side sees.
• Private notes. Lines marked NOTE - DON'T SAY, like your lowest price, guide the answers but are never shown as words to say.
• Phone view. The same answers on your phone over your own Wi-Fi, so nothing is on screen at all.
• Local speech to text. Runs on your computer by default. A faster cloud option is there if you want it.

📄 After the call

• Summary. What was discussed, in a few plain sentences.
• Decisions and action items. Who does what, and by when.
• Follow-up message. A short, friendly message ready to send.
• Word export. Everything above, plus the transcript and your notes, as a .docx file.

Which AI writes the answers

Pick whichever you already have. You can change it any time under Dashboard → Settings → Main brain.

Times are measured from the moment the question is sent, on a real account. Speech to text adds its own time on top, see Speed.

If Claude fails in the middle of a meeting (a usage limit, an expired login), the app switches to a backup on its own and keeps answering: the OpenAI key if you set one, otherwise ChatGPT if the Codex CLI is signed in.

Install in one command

Copy one line, paste it, press Enter. It installs everything the app needs and opens it when it is finished. It takes 5 to 10 minutes the first time.

Windows 10 or 11: open the Start menu, type PowerShell, open it, paste this line and press Enter:

irm https://raw.githubusercontent.com/tanzeeldevAi/ai-meeting-assistant-copilot/main/install.ps1 | iex

Mac (macOS 11 or newer): open Terminal (press Cmd + Space and type Terminal), paste this line and press Enter:

curl -fsSL https://raw.githubusercontent.com/tanzeeldevAi/ai-meeting-assistant-copilot/main/install.sh | bash

They install ChatGPT's command-line tool (Codex) in place of Claude's.

Windows:

$env:MC_AI='chatgpt'; irm https://raw.githubusercontent.com/tanzeeldevAi/ai-meeting-assistant-copilot/main/install.ps1 | iex

Mac:

curl -fsSL https://raw.githubusercontent.com/tanzeeldevAi/ai-meeting-assistant-copilot/main/install.sh | MC_AI=chatgpt bash

Already installed with the first line? Run one of these and it adds ChatGPT; your meetings and settings stay.

What the command does

1. Downloads the app.
2. Installs Node.js and Python inside the app's own folder if your computer does not have them. It does not ask for an administrator password and does not touch the programs already on your computer.
3. Installs the speech packages and the speech model.
4. Looks for Claude or ChatGPT. If it finds neither, it installs Claude's command-line tool (or ChatGPT's, with the lines above).
5. Adds a shortcut: on Windows to the desktop and the Start menu, on a Mac to Launchpad and Spotlight.
6. Opens the app.

Updating keeps your saved meetings and settings.

Connect your AI

When the app opens it looks for Claude and ChatGPT on your computer by itself:

The first time on a Mac

macOS asks for two permissions. Allow both for Electron:

• Microphone, to hear you
• Screen & System Audio Recording, to hear the other person (no video is recorded)

If macOS offers Quit & Reopen after you allow it, quit, then open Meeting Copilot again.

An older Mac (macOS 11 or 12)

It works, with one difference. Before macOS 13, a Mac cannot share its own sound with apps, so the app hears the call through the microphone:

• Use the Mac's speakers, not headphones, so the microphone hears the other person.
• Your words and theirs come in as one voice, so now and then it may answer a question you asked yo
