Open-source AI copilot hides from Zoom, mostly

What it does

cue is an Electron app that parks a transparent, always-on-top panel over your desktop. It captures your screen, microphone, and system meeting audio as three separate streams, then pipes them—on demand—to your own OpenAI, Anthropic, or Gemini key for real-time transcription and answers. The idea is to act as a live wingman for coding questions or awkward silences in meetings, without running a backend server.

The interesting bit

The project’s entire privacy model rests on a single macOS window flag, NSWindowSharingNone, which is the same mechanism Zoom uses to hide its own toolbar from recordings. cue leans on this to keep its glass UI out of screen shares, though the README is admirably upfront that this is best-effort: macOS 15.4+ capture tools can ignore the flag, and a phone camera always will.

Key highlights

• Bring-your-own-key only: no accounts, no telemetry, no server; API keys live in a local cue-data.json file.
• Three-channel audio design: it keeps your mic input and meeting loopback audio separate so the LLM knows who said what.
• Triggered capture: screenshots and audio are sent to the provider only when you invoke a feature, not continuously.
• Built-in résumé field: you can paste your professional background so career-related answers are factored against your actual experience.
• GPL-3.0 and intentionally small: plain HTML/CSS/JS, no build step for hacking on it.

Caveats

• Invisibility is best-effort, not guaranteed; modern macOS capture APIs and physical cameras can still expose the window.
• The README carries a strong ethical disclaimer: using it during proctored exams, job interviews, or recorded meetings may violate platform rules and local consent laws.
• Anthropic keys cannot handle speech-to-text, so you will need a second provider if you want the listening features.

Verdict

Developers who want a hackable, offline-first-ish AI overlay for personal productivity or accessibility should look here; anyone seeking a guaranteed invisible cheating tool will be disappointed—and explicitly told to look elsewhere.
