A comprehensive, head-to-head comparison between Stealthify and LockedIn AI. Compare hardware-isolated screen-share stealth, stability, and Ghost Mode click-through.
Key Takeaways
Hardware Display Isolation vs. Extension Vulnerabilities: LockedIn AI relies heavily on browser extensions and standard window layers that can leak during full-desktop screen shares. Stealthify isolates rendering at the physical hardware buffer layer with Display Shield™, guaranteeing 100% invisibility across Zoom, Teams, Meet, and Discord.
Autonomous Real-Time Speed vs. Human Dependency: LockedIn AI markets "LockedIn Duo" (requiring a third person to feed you answers). Stealthify provides instantaneous, autonomous, sub-second AI cues (< 400ms) without human bottlenecks.
True Ghost Mode (Click-Through): Stealthify allows you to write code in VS Code, LeetCode, or CoderPad directly through the teleprompter. LockedIn AI’s window intercepts mouse clicks, blocking IDE interaction.
Native Desktop Stability: Built as a lightweight native binary (< 60MB RAM) that never crashes mid-interview, avoiding the freezes and disconnection issues common with browser-based extensions.
In the competitive world of remote technical and behavioral interviewing, candidates seek tools that give them confidence and real-time guidance without increasing their stress levels.
LockedIn AI (also known as Lockedin AI) emerged as an interview assistant offering real-time suggestions and a "Duo" mode for external human assistance. However, candidates frequently report major challenges: extension visibility during screen shares, unexpected mid-interview crashes, and mouse click blocking during live coding assessments.
Stealthify eliminates these vulnerabilities. Built as a native desktop application with hardware display isolation and Ghost Mode click-through, Stealthify provides dependable, undetectable intelligence for your highest-stakes conversations.
Comprehensive Feature & Architecture Comparison
The table below outlines the key architectural and operational differences between Stealthify and LockedIn AI:

| Technical Interview Support | ✅ Algorithmic proofs, time/space complexity | ⚠️ Basic question answering |
1. Hardware Display Shield™ vs. Browser Extension Vulnerabilities
The primary concern of any candidate using an interview assistant is absolute screen-share security.
The Risk of Browser Extensions:
LockedIn AI relies on browser extensions and web overlays:
Full Desktop Screen Sharing: When an interviewer asks you to share your "Entire Desktop" on Zoom or Google Meet, browser extensions, taskbar icons, and overlay windows can be captured in the video feed.
Window Switching Glitches: Switching between browser tabs or virtual desktops can cause overlay windows to flicker or linger in the captured screen feed.
The Stealthify Display Shield™ Standard:
Direct Hardware Isolation: Stealthify renders strictly to your physical monitor's display buffer.
100% Invisibility Across All Platforms: Whether sharing a single window or your entire desktop on Zoom, Microsoft Teams, Google Meet, or Discord, your shared video feed remains completely clean.
Zero Risk of Detection: Remote viewers see only your clean code editor or slide deck.
2. Autonomous Sub-Second AI vs. The "LockedIn Duo" Bottleneck
LockedIn AI promotes "LockedIn Duo", a feature allowing a third-party friend or mentor to join your session remotely and type answers for you during the live interview.
Why Human Dependency Fails:
Severe Latency: A human assistant must listen, understand the question, think of an answer, and type it out—creating a 6-to-10 second delay that makes the candidate appear completely unprepared.
Scheduling & Privacy: Coordinating a third person for every screening call creates massive scheduling friction and exposes private career discussions.
The Stealthify Autonomous Advantage:
Instantaneous AI Stream (< 400ms): Stealthify extracts semantic intent instantly and streams concise talking points before you finish your breath.
Grounded in Your Real Career: Automatically draws from your uploaded resumes, system design whitepapers, and verified project metrics.
3. Ghost Mode: Frictionless Live Coding
During technical interviews (LeetCode, HackerRank, CoderPad, VS Code), you must write code, execute test cases, and navigate files while referencing guidance.
LockedIn AI: Standard overlay window that captures mouse clicks and keyboard focus. Having it positioned over your IDE prevents you from clicking into code lines without dragging the window away.
Stealthify Ghost Mode: Press a single hotkey to activate Ghost Mode. The teleprompter becomes completely click-through. You can type in VS Code, scroll test suites, and compile code directly underneath your live hints.
4. Rock-Solid Native Stability vs. Mid-Interview Crashes
One of the most frequent complaints regarding browser-based interview assistants is unreliability—the AI suddenly freezing or crashing halfway through a live call.
| Reliability Dimension | Stealthify | LockedIn AI |
|---|---|---|
| Architecture | 🚀 Native Compiled Desktop Binary | ⚠️ Browser Extension / Chromium Layer |
| RAM Footprint | 💻 Ultra-Lean (< 60MB RAM) | ⚠️ 500MB – 900MB RAM |
| Connection Stability | 🛡️ Direct, Resilient Streaming Pipeline | ⚠️ Extension disconnects & token drops |
| Audio Capture | 🎙️ Direct Device Audio Pipeline | ⚠️ Virtual audio / browser tab capture |
5. Privacy, Data Sovereignty & Model Training
On-Device Document Parsing: Stealthify processes your uploaded resumes and whitepapers directly on your machine, extracting lightweight semantic context locally without transmitting massive raw files across the web.
Zero Model Training: Your private resume metrics, conversation audio, and technical answers are never used to train public foundation AI models.
Sovereign Deletion: With one click, all session data, meeting transcripts, and persona files can be permanently erased from your account.
Decision Matrix: Which Tool Fits Your Needs?
Choose LockedIn AI if:
You specifically want a friend or human mentor to manually type answers for you during mock interviews using the "Duo" feature.
You prefer running tools via browser extensions without downloading a standalone native desktop app.
Choose Stealthify if:
You need 100% screen-share invisibility with Display Shield™ during live technical evaluations on Zoom, Teams, Meet, or Discord.
You want an autonomous, sub-second AI teleprompter that delivers concise cues in < 400ms without human delays.
You need Ghost Mode click-through to write code in IDEs while reading live algorithmic proofs and STAR talking points.
You require rock-solid native desktop stability that never freezes or crashes mid-interview.
