The meeting copilot that answers in your headset

callAssistX listens to your meeting and answers the questions put to you, explains what is on your screen, and writes the minutes when the call ends. Speech recognition runs on your PC; answers come from the AI provider you choose, with your own key.

Free to use with local transcription. Pro trial for 7 days, no card needed.

Them How would you keep the cache consistent when two services write the same row?

Answer

Write-through with a version check, and invalidate on the write path rather than on a timer.

  • Each row carries a version; the cache rejects an older one
  • Writers publish an invalidation after commit
  • Short TTL as a safety net, not the mechanism

Spoken in your headset while it streams. Audio stayed on this PC.

How it works

Three steps, about five minutes

  1. Step 1

    Install

    Download the installer and run install.ps1. It installs for your user only; no administrator rights needed.

  2. Step 2

    Sign in

    The setup wizard signs you in with Google, checks for a GPU and downloads the speech model.

  3. Step 3

    Add your AI key

    Paste a key from OpenRouter, OpenAI, Anthropic, Google Gemini or xAI here on the website. Pay the provider directly; we never mark up usage.

Features

Everything has a button and a hotkey

The hotkeys work while Teams, Zoom or any other window has focus. The window, its menus and dialogs never appear in your screen shares.

Ctrl+Alt+L

Listen

Press once to start, again to stop and get a brief, speakable answer about that stretch of conversation.

Ctrl+Alt+A

Ask

One press answers the last few seconds, no need to start listening first.

Ctrl+Alt+S

Scan

Explains the shared slide or dashboard on your screen, in context of what was just said.

Ctrl+Alt+D

Solve

Solves the problem on screen: code, complexity, dry run and edge cases. Copy code copies just the code.

Explain

Pick any transcript line: the answer pane explains it, its jargon, and what you could say back.

Minutes

When a meeting ends, the recording is re-transcribed in full and the minutes list summary, decisions, action items and open questions.

Memory

Answers draw on your project notes and past meetings and say which source they used. The index stays on your PC.

Ctrl+Alt+O

Minimal mode

A see-through strip at the top of the screen with only the answers; clicks pass through it. Hidden from screen shares.

Interview mode

A meeting type that shapes answers for interviews. Review, Demo, Stand-up and General are built in too; the app suggests one from the conversation.

Privacy

Private by design

Meeting audio never leaves your PC. Transcript snippets and screenshots pass through our server to the AI provider you chose and are not stored. Your provider keys are stored encrypted and used only for your requests.

The desktop app never holds a key or a prompt. Recording other people may need their consent where you are; the app shows a notice before a recording starts.
