About this app
CloakAI is a stealthy desktop AI interview assistant that listens to your live interview, transcribes questions in real time, and feeds you contextual, structured answers through an operating-system-level overlay that screen shares, recordings, and most proctoring tools never capture. It's built for job seekers navigating behavioral, system design, and coding rounds on Zoom, Microsoft Teams, Google Meet, HackerRank, CodeSignal, CoderPad, Codility, HackerEarth, HireVue, and VidCruiter. The standout feature is the stealth overlay: it asks your OS to exclude its window from screen capture, so interviewers see only what's behind it. The new CloakAI Umbra addition lets you route the whole experience to your phone via a QR code, so nothing from CloakAI appears on your computer at all. Under the hood, speaker diarization separates your voice from the interviewer's, context capture reads your VS Code, browser tabs, shared screen, resume, and job description, and the answer pipeline targets ...

Scout Review
Written by AI from measured evidence, scored out of 100.
CloakAI is a polished-enough stealth interview assistant with a real product behind the marketing: a desktop overlay, speaker diarization, context capture from VS Code and browser tabs, and a phone-only Umbra mode. The site is coherent but not airtight — scroll-reveal animations hide sections, compatibility is plain text, and the security posture is thin for a tool whose entire value proposition is not being seen. Pricing is aggressive ($4.99/week, $17.99/month) and the free trial is genuinely free. The idea is specific and the segment is real; the moat is the question.
Measure by measure
Usability
64Free 7-day trial with no card, claimed 5-minute setup, and a changelog full of real UX fixes (focus handling, shortcuts, answer history). Mobile nav hides everything behind a hamburger.
Design
58Cohesive dark theme and a clear single green CTA, but scroll-reveal animations left whole sections invisible at capture, tiny low-contrast carousel labels, and plain-text compatibility instead of a logo row.
Speed
57Lighthouse mobile 65/100 with LCP 3.7s and TBT 969ms — the marketing page itself is JS-heavy. The product claims a 1,870ms answer pipeline, but that's a target, not a measured result.
Security
48HTTPS and HSTS enforced with SPF/DMARC, but no CSP, frame protection, or content-type sniffing guard — 6/12 header checks. No SOC 2, ISO, or pen-test claim anywhere. Core feature is evading proctoring detection.
Accessibility
78Lighthouse a11y 97/100, but two real failures: insufficient contrast and visible labels without matching accessible names. No WCAG statement or multi-language support found.
Growth
58Real, specific problem with a genuine wedge — OS-level capture exclusion and phone-only mode — aimed at a high-intent segment. But the category is crowded and the moat is a detection arms race.
Improvement areas
- Missing security headers (CSP, frame protection, X-Content-Type-Options, Referrer-Policy, Permissions-Policy) and no published audit.
- Scroll-reveal animations leave sections invisible on first paint; carousel labels are tiny and low-contrast.
- Two failing accessibility audits (contrast, accessible names) and no WCAG statement or multi-language support.
Design & Usability
The landing page has a coherent identity — dark theme, restrained type, one unmistakable green CTA — and the hero demo mockup communicates the split-screen overlay concept instantly. But the visual audit caught scroll-reveal animations mid-flight, leaving entire sections as empty dark bands, and the compatibility claim ('Zoom, Teams, Meet and 7 more') is plain text where a logo strip would actually sell trust. Usability is stronger: a free 7-day trial with no credit card, a claimed 5-minute setup, and a changelog that documents real fixes — focus handling, custom shortcuts, answer history. Mobile navigation collapses everything behind a hamburger, and the carousel competes with the CTA for attention.
Speed & Security
Speed is measured, not claimed: Lighthouse mobile 65/100, LCP 3.7s, TBT 969ms. The marketing page is heavier than it looks, and the product's own 1,870ms answer pipeline is a stated target, not a benchmark. Security is the weak flank. The header probe found HTTPS and HSTS in place with SPF and DMARC, but no CSP, no frame protection, no content-type guard — 6 of 12 checks. There is no SOC 2, ISO, or pen-test claim anywhere in the collected content, and the product's core premise is evading third-party screen capture, which makes the absence of published security posture harder to wave off than it would be for a normal SaaS.
Accessibility & Growth
Accessibility scores 97/100 on Lighthouse but fails two real audits — insufficient contrast and visible labels without matching accessible names — and the visual review independently flags tiny low-contrast grey labels on near-black. No WCAG statement or multi-language support is mentioned. Growth is the interesting one: the problem is real and the segment is specific (technical candidates across ten named platforms), and the wedge — OS-level capture exclusion plus phone-only Umbra mode — is concrete. But Interview Copilot and Final Round AI already sell real-time interview answers, so CloakAI's differentiation is stealth, not substance. That's a detection arms race, not a moat, and the category has room but not much patience.
Conclusion
If you're a technical candidate in a heavy interview cycle and you're going to use one of these tools anyway, CloakAI is a credible pick — the Umbra phone mode is a genuinely different angle, and the changelog shows the team ships. But go in clear-eyed: the security headers are half-there, there's no audit, and the entire premise depends on staying ahead of proctoring detection. That's a bet on the vendor's update cadence, not a guarantee. And ethically, using it in a proctored assessment is on you, not on the landing page.
Suggestions for improvement
- Fix the scroll-reveal timing so sections render fully on first paint — the visual audit caught half the page invisible.
- Replace the plain-text 'Works with Zoom, Teams, Meet and 7 more' line with an actual logo strip; compatibility is the trust hook.
- Ship the missing security headers (CSP, X-Content-Type-Options, Referrer-Policy, Permissions-Policy) and publish a security page.
- Fix the two failing a11y audits — contrast on carousel labels and accessible-name matching — they're cheap wins on a 97 score.
