Beyz AI is a newer browser-based interview copilot with a clean Chrome-extension experience. PhantomCode is a mature native desktop app with verified screen-share invisibility, 56 spoken languages, and an exportable after-interview transcript. Here is the balanced breakdown — where each tool wins, and how to choose.
Browser extensions render in the same compositing layer as the page you share. PhantomCode runs as a separate native process and is excluded from capture frames entirely.
56 primary languages plus 6 bilingual modes. If your interview switches between English and Hindi, Mandarin, Tamil, Spanish, or Arabic mid-call, PhantomCode keeps up.
Every session produces an exportable transcript of questions and answers. Use it to find weak spots, prep follow-up rounds, and improve over time.
The columns below cover the categories that actually decide an interview: real-time assistance, voice awareness, invisibility, form factor, language coverage, maturity, and pricing.

Marketing pages talk about features. Real interviews come down to a small number of decisions that change the outcome. Here are the five that matter most when choosing between Beyz AI and PhantomCode.
This is the headline difference and the one most candidates miss. A Chrome extension renders its UI inside the same browser window you are sharing. Side panels, response cards, and overlays all show up in the screen-share stream because the compositor draws them onto the same surface as the tab. Beyz being in the browser is convenient when you are not sharing — and a problem when you are. PhantomCode runs as a separate native desktop process. The interviewer sees your editor, your IDE, your shared tab — and not the assistant. That gap holds across Zoom, Google Meet, Microsoft Teams, OBS, QuickTime, and proctoring tools.
Beyz AI is a newer entrant and that shows in two ways. Positively, the interface feels modern and the surface area is small enough to be coherent. Less positively, the deeper feature surface — DSA solving with complexity analysis, full system-design support, SQL rounds, OA support, profile-aware replies, two AI thinking modes, custom prompt management — is where mature tools have spent years iterating. PhantomCode has been battle-tested across thousands of real interviews, and the rough edges that only appear in specific situations (proctored OAs, system-design whiteboards, multi-hour onsites) have been smoothed out.
PhantomCode supports 56 spoken languages plus 6 bilingual modes. That includes Arabic, English, French, German, Hindi, Italian, Japanese, Korean, Mandarin, Polish, Portuguese, Russian, Spanish, Tamil, Turkish, Vietnamese, and many more. Real interviews — especially in India, the Middle East, Latin America, and Southeast Asia — frequently switch between English and a regional language mid-call. PhantomCode keeps up; narrower-coverage tools drop transcription quality the moment the panel switches. If you are interviewing in a single language and that language is well-covered by Beyz, this difference may not apply to you. If you are not, it is the deciding factor.
PhantomCode produces an exportable transcript of every interview session — the questions the interviewer asked, the AI responses, your timing, and the topics covered. This is how you turn one interview into ten, by reviewing what came up and prepping for the follow-up round. Beyz AI's product is built around the live copilot moment; we have not seen an equivalent post-call transcript export at the time of writing. If you are running a multi-round loop and want to improve between rounds, this gap is significant.
PhantomCode ships native binaries for macOS and Windows with feature parity: same hotkeys, same audio routing, same invisibility behavior, same UI. A Chrome extension is portable across operating systems by definition, but it inherits whatever Chrome's screen-share behavior is on each OS — which is the same problem on all of them, just consistently visible. PhantomCode's parity matters if you are on Windows for work and macOS at home, or if your interview machine changes between rounds.
Beyz is a credible pick — there are real workflows where it is the right tool. Be honest with yourself about which situation you are actually in.
The situations where a browser extension is the wrong shape for the job. If any of these apply, PhantomCode is the right pick.
The questions candidates actually ask before switching from Beyz AI or picking between the two. Answered straight, no marketing fluff.
If your round is Chrome-only and lightweight, Beyz AI is a fair pick. If it involves screen-share, recording, multilingual panels, coding, system design, or after-call review — that is what PhantomCode was built for.
