> ### 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.

# Stealthify vs. LockedIn AI: Hardware-Level Display Shield™ vs. Browser Extension Overlays

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.**

```mermaid

    subgraph LockedIn_Model["LockedIn AI (Browser Extension Model)"]
        L1["Interview Begins"] --> L2["Browser Extension / Web Overlay Active"]
        L2 --> L3["Screen Shared: Extension Leaks in Video Stream"]
        L3 --> L4["Window Blocks Mouse Clicks in IDE"]
        L4 --> L5["Mid-Call Freezes & Detection Risk"]
    end

    subgraph Stealthify_Model["Stealthify (Hardware Display Shield™)"]
        S1["Interview Begins"] --> S2["Native Desktop Engine Active (< 60MB RAM)"]
        S2 --> S3["Display Shield™ Isolates Hardware Buffer"]
        S3 --> S4["Ghost Mode: Type Code Directly Through Prompter"]
        S4 --> S5["100% Undetectable, Stable, Sub-Second Delivery"]
    end
```

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.

## 1. Hardware Display Shield™ vs. Browser Extension Vulnerabilities

The primary concern of any candidate using an interview assistant is **absolute screen-share security.**

```mermaid
graph TD
    A["Your Physical Monitor"] -->|"Hardware Rendering"| B["You See Live Teleprompter & Complexity Proofs"]
    C["Screen Sharing Stream (Zoom / Teams / Meet)"] -->|"Display Shield Filtering"| D["Interviewer Sees Clean Code Editor Only"]
```

### 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.

```mermaid
graph LR
    subgraph Duo_Model["LockedIn Duo (Human-in-the-Loop)"]
        D1["Interviewer Asks Question"] --> D2["Remote Friend Listens"]
        D2 --> D3["Friend Types Answer"]
        D3 --> D4["6-10s Delay → Unnatural Silence"]
    end
    
    subgraph Autonomous_Model["Stealthify Autonomous Stream"]
        A1["Interviewer Asks Question"] --> A2["Sub-Second Semantic Whisper (< 400ms)"]
        A2 --> A3["Immediate First-Person Cues in Eye Line"]
    end
```

### 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.

```mermaid
graph LR
    subgraph Standard_Overlay["Standard Overlays (LockedIn AI)"]
        W1["Window Intercepts Mouse"] -->|"Blocks Interaction"| W2["Must Move Window Away from Code"]
    end
    
    subgraph Stealthify_Ghost["Stealthify Ghost Mode"]
        G1["Click Directly Through Overlay"] -->|"Zero Mouse Friction"| G2["Type Code & Run Tests Seamlessly"]
    end
```

- **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.

### 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.
