Lumi Desk sits quietly on your Mac, listens in real time, and works as an AI interview assistant, interview note taker, and cheap alternative to Cluely and Final Round AI.
macOS 14+ (Sonoma) · Bring your own OpenAI API key
Lumi Desk is built for the exact high-intent searches people use when they want a private, low-cost interview AI tool on macOS.
Lumi Desk is an AI assistant for interview prep, live interview support, and follow-up note review. It listens in real time, references your resume, and helps answer questions with your own context.
If you need an AI interview note taker, Lumi Desk captures system audio, creates a live transcript, remembers prior questions, and exports structured notes after the session.
Looking for a cheap solution for interviewing? Lumi Desk is $9.99 once, instead of another monthly interview AI subscription layered on top of your API usage.
Some people also search for terms like interview cheating AI. Lumi Desk matches that intent cluster as a private, invisible-on-screen-share macOS interview assistant, while still focusing on transcript quality, context, and note-taking.
Four simple steps to ace your next interview.
Add resume, job description, past Q&As. AI references your actual experience — not generic advice.
One click to begin. Audio is captured continuously from your video call.
Click Ask AI or type a question. AI answers using transcript + your resume + conversation history.
The overlay is hidden from Teams, Meet, and Zoom screen sharing. OS-level stealth.
If you are searching for a Cluely alternative, Final Round AI alternative, or a cheaper interview assistant, this is the direct comparison.
Lumi Desk is a one-time purchase at $9.99. That makes it a much cheaper interview AI than subscription-heavy competitors like Cluely or Final Round AI.
Your notes stay on your machine. Lumi Desk is designed for people who want a macOS interview assistant without handing their resume and history to another cloud dashboard.
Many people want both an interview note taker and a response helper. Lumi Desk combines live listening, transcript memory, screenshot analysis, and exportable notes.
Same features as $96/month tools — for a one-time payment.

| BM25 search accuracy | Query "leadership" → finds behavioral chunk. Query "URL shortener" → finds design chunk. Query "two sum" → finds coding chunk. |
| Anti-hallucination | 3 seconds of silence → zero utterances. Welsh/Vietnamese garbage → blocked by 8-layer filter. Music lyrics misinterpreted as speech → suppressed. |
| Encryption | Saved .enc file on disk → plaintext NOT visible in raw bytes → decrypts correctly on load. |
