Stealth Interview is a competent real-time copilot for coding and system design rounds, with a clean minimalist desktop app and decent overlay-stealth on Zoom and Google Meet. The catch: pricing starts at $49/mo (no monthly bundle under that), behavioral interviews aren't a focus, and there's no question bank or mock-interview library to prep with.
Stealth Interview's pricing page lists three tiers: Starter at $49/month (the only true monthly option), Premium at $150 for 6 months (~$25/mo, marked Popular), and Hunter at $250/year (~$21/mo). The cheaper effective rates require a 6-month or 12-month commitment paid up front. Per the official pricing page there's no full free trial of live features — only a limited demo mode — and the refund policy is a 7-day money-back guarantee. Coverage is Zoom and Google Meet (Microsoft Teams isn't called out on the landing page), and the product positions itself around coding and system design rather than behavioral rounds. If you're optimizing for prep + real-time in one tool, this is a real-time-only product.
- Desktop app for macOS and Windows
- Real-time system audio + conversational AI
- GPT-5.2, GPT-5 Mini, GPT-5 Nano models
- Unlimited usage on the Starter plan
- Premium tier adds Claude Opus 4.5 + priority support
- 7-day money-back guarantee · no full free trial of live features
What the reviews and the landing page don't put on the pricing card
Public review volume is thin. Trustpilot shows only a handful of ratings on stealthinterview.ai — not enough signal to validate the product the way you can with longer-tenured tools. The single most-quoted positive review is about resume-based suggestions for behavioral questions; most other public commentary focuses on ethical concerns about using AI mid-interview rather than the tool's reliability under load.
Third-party reviewers flag the same structural risks every desktop interview-AI faces: eye-movement tells, response-delay tells, robotic phrasing if you read answers verbatim, and the fact that no overlay is provably undetectable across every monitoring stack and every OS update. Stealth Interview's landing page is brand-forward ("Undetectable Interview AI") but doesn't publish a detection-test methodology or a list of platforms it's been verified against beyond the Zoom and Google Meet implication.
On feature scope: there's no question bank, no mock-interview mode, and behavioral interview support is described as limited by reviewers. If you want to prep before the interview as well as get help during it, you'll be combining Stealth Interview with another product. That math matters when the cheapest non-commitment plan is already $49/month.
“Worked well for the live coding round, but I still did all my behavioral prep with another tool — Stealth Interview doesn't really have anything for that.”
Stealth Interview vs Interview Sidekick
Stealth Interview is a desktop AI tool branded as 'Undetectable Interview AI' that offers one-click coding problem solving in real-time during live interviews.

How to Use Stealth Interview
Stealth Interview is a downloadable desktop app for macOS or Windows. After install, you launch it before your coding interview and trigger it with a hotkey when you encounter a problem — the AI analyzes the question on your screen and surfaces a Python (or other language) solution on a hidden overlay invisible to screen sharing. The flow is intentionally minimalist: download → open → press hotkey → get answer.
How to Use Interview Sidekick
Getting started with Interview Sidekick is quick and designed to help job seekers practice and improve their interview skills with AI-powered coaching, 16,000+ real interview questions, and a real-time copilot that works on Zoom, Google Meet, Microsoft Teams, and Webex.
