An invisible assistant for any interview
Technical, product, behavioral, a case, or in English — Vizir hears the conversation and in a couple of seconds gives you a ready answer, even to a question you didn't prepare for. The overlay stays hidden during a screen share, and where macOS would reveal it, hints go to a phone you don't share.
7 days free · no card · macOS 14.4+ · Apple Silicon · Windows 10/11
The overlay is excluded from screen capture during a browser share and on macOS ≤ 14. On macOS 15+ with the native client — turn on the companion.
Four tabs — for any situation in an interview
We've modeled a huge range of situations that come up in interviews and built Vizir to have you covered in each one. Every typical situation gets its own tab: the first hears the conversation, the second hints on the interviewer's question, the third solves the problem from your screen, the fourth explains what you've already said.
Hears and transcribes the conversation
A live transcript of the call split into "Interviewer / You", in Russian and English. You always see exactly what was said — speaker echo is filtered out.
Hints on the interviewer's question
A question comes up — press ⌥↩ and Vizir reads the flow of the conversation, then gives you talking points for a spoken answer in a couple of seconds.
Solves the problem from your screen
Got the problem as text or an image? Take a screenshot ⌥C or copy the selection ⌥⇧C, press ⌥↩ — and the AI returns a ready-made solution with code, a walkthrough, and complexity analysis.
Explains what you've already said
Asked to clarify your own answer? Select a passage in "Hint" or "Solution", press ⌥E — and a breakdown of exactly that part appears in the fourth tab, continuing your train of thought.
A live example: from transcript to explanation — what only you can see.
A dictionary of seen numbers: O(n) time, O(n) memory. For each n we check target − n.
Even when the whole screen is visible — the hints are yours alone
The overlay doesn't make it into a tab, window, or browser share. And for the cases where the interviewer sees your whole screen directly, there's the companion: any second device next to you — a phone, a tablet, or a second laptop. Only hints, as text, are sent to it, end-to-end encrypted; you don't share that device's screen, and the audio stays on your computer.
A browser share (Zoom/Meet in a tab), screen share and screen recording on macOS ≤ 14 — the overlay doesn't make it into the picture.
Native Zoom/Teams on macOS 15+, or whenever the interviewer sees your whole screen — read the hints from the companion.
