Visibility map
Where the overlay is hidden during screen sharing and where it can be seen — by client and OS version.
Features
Vizir features
Vizir is an AI interview assistant that hears the conversation on two channels, transcribes speech in real time, and on a hotkey serves up a hint or a ready-made solution — on a screen only you can see: an overlay that stays out of browser screen sharing, or your phone when the whole screen is captured. Below is exactly what the app can do, and how it looks.
The panel
Four windows — and what you can do from each
The panel switches from the keyboard. Each window handles its own job — from the live dialogue to a line-by-line code walkthrough. Here's how it looks and what it does.
Tab 1 · Transcript
A live dialogue on two channels
Hears both the interviewer (audio from Zoom, Meet, or the browser) and you through the mic — as two tracks, natively, with no virtual audio drivers. Lines are split into "Interviewer / You", by time, in Russian and English. Speaker echo is filtered out.
What you can do from here
- ⌥↩generate a hint or solution from the whole conversation
- ⌥1⌥4switch to any tab
- ⌥↑⌥↓scroll the transcript
Tab 2 · Hint
What to say out loud right now
A short answer to the interviewer's last question, in the context of the conversation. Not paragraphs of theory — what people actually say out loud, in a couple of seconds.
What you can do from here
- ⌥Eexplain a selection — the breakdown goes to "Explanation"
- ⌥Vcopy the hint
- ⌥↑⌥↓move through the answer line by line
Tab 3 · Solution
Ready-made code with a walkthrough and complexity
The problem came as text or an image: screenshot ⌥C or the selection ⌥⇧C, then ⌥↩. Returns code with line numbers, a walkthrough of the approach, and complexity analysis. A vision model reads the image — you can attach several frames.
What you can do from here
- ⌥C⌥⇧Cscreenshot the prompt · grab selected text
- ⌥↑⌥↓move through the lines — read it out without losing your place
- ⌥E⌥Vexplain the selected lines · copy
Tab 4 · Explanation
A breakdown of what you've already said
When they ask you to clarify your own answer: select a passage in "Hint" or "Solution", press ⌥E — and a breakdown of exactly that part appears here, continuing your train of thought instead of starting over.
What you can do from here
- ⌥Efrom "Hint" or "Solution" — fill this tab

One shared context
All four windows remember the same thing
The problem statement, the last solution it produced, and the tail of the conversation are shared across every tab. So "why this way?" and "what's the complexity?" are answered against what it already produced, not from scratch in the abstract. Vizir only sees your code if you show it with a screenshot (⌥C) or a selection (⌥⇧C).
The same hints work outside interviews too — standups, webinars and client calls. Where that pays off, and what to tell the other participants, is in an AI assistant for work calls.
Controls
Everything from the keyboard
No mouse needed. Generating, tabs, screenshots, moving and resizing the window — it's all on hotkeys, so your hands never leave the keyboard during the interview.
⌥↩
Generate a hint or a solution from the current context.
⌥1 ⌥2 ⌥3 ⌥4
Switch tabs: Transcript, Hint, Solution, Explanation.
⌥C
Task snapshot — capture the problem statement or a diagram for the vision model (you can stack several).
⌥⇧C
Grab the selected text — the problem statement or a code snippet, for example.
⌥\
Hide or show the overlay with a single key.
⌥W ⌥A ⌥S ⌥D
Move the overlay window up, left, down and right.
⌥+ ⌥−
Make the window bigger or smaller.
⌥↑ ⌥↓ ⌥← ⌥→
Navigate line by line through the answer and scroll the content of the active tab.
Visibility
Out of screen sharing — and what to do when it isn't
During browser screen sharing and in most capture paths the overlay stays hidden. Where it can be visible (native clients on macOS 15+, local recording), hints move to the phone companion. Honest, per-scenario breakdowns are on separate pages.
Phone companion
Hints on a phone you don't share — end-to-end encrypted.
