AI interview assistant for Zoom
Co-Help runs alongside Zoom as an invisible overlay — listening, transcribing, and surfacing instant AI answers during your interview, without appearing on a shared screen.
How Co-Help works with Zoom
Co-Help isn't a Zoom app or plugin — it doesn't need Zoom's permission or App Marketplace approval, and there's nothing to install inside Zoom itself. Instead, it runs as a separate desktop overlay on top of Zoom, capturing your computer's system audio (which includes whatever Zoom is playing) through your operating system's built-in loopback capture. That means it works the same way whether you're on a Zoom call, a Teams call, or any other browser or desktop app that plays audio through your speakers.
During the call, Co-Help transcribes both what you say and what the interviewer says in real time, then races 9 AI models in parallel the moment a question is detected, surfacing the fastest strong answer on your private overlay.
Staying invisible on Zoom screen share
When you share your screen on Zoom, other participants see your Zoom window — not your desktop's overlay layer. Co-Help's overlay uses a click-through window with screen-capture protection, so it stays invisible to Zoom's screen-share output while remaining fully visible to you on your own display.
Rules vary by employer and platform. Some companies and assessment platforms explicitly restrict outside tools during interviews. Check the rules for your specific interview before using any assistant, including Co-Help.
Getting started on Zoom
- Choose a plan and download. After checkout, you're taken straight to the download page for Windows or macOS.
- Install and sign in. Run the installer, then sign in with the email you paid with — your AI access activates automatically.
- Join your call as usual. Open your meeting normally; Co-Help runs as a separate overlay, not a plugin inside it.
- Let it listen and answer. Co-Help transcribes both sides of the conversation via system audio and races 9 AI models for an instant answer on your private overlay.
What Co-Help brings to a Zoom interview
- Live transcription of both sides of the call via your system's audio, no microphone needed to hear the interviewer.
- 9 AI models raced in parallel — GPT, Claude, Gemini, and more — so the first strong answer wins.
- Screenshot Q&A for code or diagrams shared on Zoom.
- Your knowledge base — resume, projects, and notes — so answers reflect your real experience.

Frequently asked questions
Can Zoom or my interviewer see Co-Help when I share my screen?
No. Co-Help's overlay uses screen-capture protection and a click-through window, so it does not appear in Zoom's screen-share output, recordings, or on the interviewer's side, even while you can still see and use it yourself.
Do I need a Zoom plugin or app to use Co-Help?
No. Co-Help is a separate desktop app that runs alongside Zoom. It captures system audio at the OS level rather than integrating with Zoom directly, so there's nothing to install inside Zoom.
Is it allowed to use an AI assistant during a Zoom interview?
Rules vary by employer and by the assessment platform some companies use for technical screens. Some explicitly prohibit outside tools; others don't address it. Always check the specific rules for your interview before using any AI assistant, including Co-Help.
