Webex Interview AI: Real-Time Copilot Hidden From Screen Share

Acedly is a Webex interview AI — a real-time copilot that hears the question, drafts a résumé-grounded answer, and stays hidden from Webex screen sharing in under 200 ms. What to test before your next Cisco Webex interview.

What a Webex interview AI actually is

A Webex interview AI — also called a Webex interview assistant — is a desktop application, not a browser tab, that sits beside your Cisco Webex client during a live interview. It does three things in order: it captures the interviewer's audio off the system loopback, transcribes and reasons about the question, and renders an answer on a surface excluded from Webex's screen-sharing pipeline. The whole loop has to fit inside the pause between the end of a question and the moment you'd normally start talking — about 200 milliseconds.

Webex is the enterprise-heavy platform in this category: it shows up most in interview loops at larger, often regulated employers, and Cisco ships its own meeting AI (the Webex AI Assistant, real-time transcription, and meeting summaries). None of those features change what a candidate-side copilot has to do — they operate on the meeting audio and shared content, not on your local, non-shared windows — but they're the reason candidates ask whether a copilot is safe on Webex specifically.

The defining number for the category is end-to-end latency, measured from the last syllable of the interviewer's question to the first character of the answer on your screen. The right target is sub-200 ms; Acedly's median on consumer hardware is roughly 98 ms, and the audio path is identical across all eight verified platforms, so Webex performs the same as Zoom.

Why the desktop app matters on Webex

Webex runs as a native desktop client for nearly every interview. That is good news: a native client is exactly where OS-level capture exclusion works. Acedly sets NSWindowSharingNone on macOS and WDA_EXCLUDEFROMCAPTURE on Windows, so when Webex shares a window or the entire screen, the buffer it captures does not include Acedly's window. A browser-tab tool has neither flag available and is one Alt-Tab away from being seen.

Webex's share modes — share-application, share-screen, and the in-meeting switcher — all route through the same OS capture path that the exclusion targets. The honest way to trust this is not a marketing page: run a Webex test meeting with a friend, share each way, and confirm Acedly is absent before your real interview.

How to verify it on Webex in ten minutes

  1. Start a free Webex meeting and invite a friend on a second device.
  2. Open Acedly and your résumé + the JD, as you would for the real call.
  3. Have your friend ask scripted questions out loud; confirm Acedly hears the audio and drafts a fast, grounded answer.
  4. Share an application window, then the entire screen, then switch shares mid-call. Your friend confirms Acedly is invisible in each.
  5. Time the gap from the end of a question to the first answer token — you want it inside the natural pause.
