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:

|---|---|---|
| Stealth Engine | 🔒 Hardware Display Shield™ (100% invisible) | ⚠️ Browser Extension / Web Overlay |
| Screen Share Invisibility | ✅ 100% Guaranteed on Zoom, Teams, Meet | ⚠️ Extension can appear on full desktop share |
| Ghost Mode (Click-Through) | ✅ Yes (Type/code through teleprompter) | ❌ No (Window blocks mouse clicks) |
| Response Latency | ⚡ Sub-Second (< 400ms live stream) | ⏳ 3.0s – 5.0s processing delay |
| Operational Stability | 🛡️ Rock-Solid Native Engine (< 60MB RAM) | ⚠️ Frequent reports of mid-call freezes |
| Intelligence Model | 🤖 Autonomous Instant AI Copilot | 👥 "LockedIn Duo" (Human helper dependency) |
| Webcam Eye-Line Placement | ✅ Directly beneath webcam bezel | ❌ Standard floating window |
| Personal Context Grounding | ✅ On-Device Parsing (Resumes, metrics, STAR) | ☁️ Cloud storage uploads |
| Public AI Model Training | 🔒 Zero Training (Strict enterprise privacy) | ⚠️ Cloud-processed data policies |
| 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.
