Live transcription
Captures the call audio from your speakers and transcribes the interviewer, and optionally you, in real time.
Your real-time AI interview copilot
Get the right answer while you're still talking. Nightjar hears the interviewer and writes your answer from your resume, the job description and the company, hidden from screen share.
What is Nightjar?
Nightjar is a desktop app for Windows that helps you answer interview questions in real time. It listens to the interviewer through your computer's call audio, transcribes each question, and drafts an answer from your resume, the job description and the company, in a concise, detailed or STAR style. In coding rounds it reads the problem from a screenshot and walks you from a brute-force idea to optimal code and a dry run.
It works with Zoom, Google Meet, Microsoft Teams and Webex with nothing to connect, needs no API key, and you pay per interview after a free 10-minute trial, with no subscription.
AI interview assistant, mid-conversation
Live transcript, instant answers and screen help, all in one small overlay.

Screenshot solve
Ctrl+Shift+Enter reads the problem, or your half-written code, from the screen and continues it.
Coding rounds
Coding interview help, the way it's graded
Interviewers score how you think, not just the final code. Nightjar walks you through the answer the way they expect to hear it, one step at a time, so you can talk while you type.
“So we need the indices of two numbers that add up to the target.”
Ask
- Can numbers be negative or repeated?
- Is there always exactly one answer?
Assume: yes, exactly one pair.
“The simplest way is to check every pair with two loops.”
Time O(n²)Space O(1)
Correct, but too slow once n reaches 10⁵.
“The inner loop keeps re-scanning for target − x.”
If we could look that value up in O(1), the second loop disappears.
“I'll keep a hash map of value → index while I scan once.”
Time O(n)Space O(n)
Trade a little memory for a single pass.
nums = [2, 7, 11, 15], target = 9
| i | x | need | seen | |
|---|---|---|---|---|
| 0 | 2 | 7 | {} | store 2→0 |
| 1 | 7 | 2 | {2:0} | found → [0, 1] |
for i, x in enumerate(nums):
if target - x in seen:
return [seen[target - x], i]
seen[x] = iEdge cases: duplicates like [3, 3] work, and negatives need no special case.

Frequently asked questions
Will the interviewer see Nightjar when I share my screen?
No. On Windows 10 (version 2004) or later, the overlay is excluded from screen capture, so it doesn't appear in screen shares or recordings, even of your whole desktop. Run a quick test call before an important interview to be sure.
Does it support coding interviews?
Yes. Coding answers follow clarify → brute force → bottleneck → optimal → dry run → code, in your chosen language. Screenshot solve reads problems or your own code straight from the screen.
Do I need an API key?
No. Sign in with Google in the app and start your free 10-minute trial. Nightjar runs the AI for you.
How does payment work?
Each interview is a one-time payment of ₹500, or ₹1,200 for three (less during sales, as shown under Pricing), made on this website through Cashfree with UPI, card or net banking. One interview is one session of up to 2 hours. If a session ends before any answer is generated, the interview is returned to your account automatically. See the refund policy.
What if the app closes in the middle of an interview?
Open Nightjar again and click Start: it picks up the same session at no extra cost, for the time that's left.
Is my resume stored on a server?
No. Your resume and job description are saved only on your computer. During an interview, they're sent with each question through Nightjar's server to the AI provider (Groq) to write the answer, and they aren't stored or logged along the way. Details are in the privacy policy.
Which languages does it understand?
English (including Indian English), Hindi, Spanish, French, German, or automatic multilingual detection.
Which operating systems are supported?
Windows 10 (version 2004 or later) and Windows 11, 64-bit.
How do I get the best answers?
Paste the full job description, upload your resume with real numbers, pick the answer style for the round, and wear headphones. Our step-by-step guide walks through setup, preparation and the live call.
Windows says “Windows protected your PC”. Is that normal?
Yes. The beta installer isn't code-signed yet. Click More info → Run anyway.
