GhostDesk: The Free "Invisible AI Co-pilot" for Interviews and Meetings

2026-03-16 | ProductHunt | Official Site

The GhostDesk panel on the right is only visible on your screen. Screen recordings, screenshots, and screen shares won't catch a glimpse of it.

30-Second Quick Take

What is it?: A Windows desktop AI assistant that pops up with a hotkey and floats over any window. Its killer feature is "invisibility"—it is completely undetectable by Zoom, Teams, Meet, OBS, or screenshot tools. You see it; they don't.

Is it worth it?: Yes. If you're a Windows user, this might be the most hassle-free "invisible AI co-pilot" available—it's free, requires no registration, no API keys, and takes a minute to set up. However, be aware: these tools are ethically controversial. Using it in an interview is like dancing on a knife's edge.

The Three Big Questions

Is it for me?

Target Audience:

• Job seekers, especially software engineers facing technical interviews.
• Sales professionals who need real-time prompts during high-pressure client calls.
• Anyone who needs to "peek at notes" during a video call without being noticed.

Use Cases:

• Technical Interviews → Real-time transcription of the interviewer's questions with AI-generated reference answers and code.
• Sales Calls → When a client mentions a competitor, the AI immediately surfaces comparison talking points.
• Internal Reports → Check data or notes anytime without switching windows.
• Daily Work → An on-call AI assistant that doesn't get in the way.

Is it useful?

ROI Judgment: As a daily AI assistant, the ROI is high—it's free, convenient, and unobtrusive. As an interview tool, you'll have to weigh the risk-reward ratio yourself.

Is it satisfying?

The "Aha!" Moments:

• One-Click Invisibility: Hit a hotkey to show/hide. The fact that recording software can't see it feels like a genuine magic trick.
• Zero Config: No account registration, no API keys, no model selection. Download → Install → Use. It’s that simple.
• Voice Mode: Just talk to it. It handles the transcription, AI processing, and streams the answer back. No typing required.

Market Sentiment:

"holy shit, i built a better Cluely... it is completely INVISIBLE to your screen recorder, screen share and cannot be detected" — @naruto11eth (Regarding a similar product, Obscura, 201 likes)

"I basically open-sourced @cluely. Completely free. Open source. Undetectable / invisible UI mode. You only pay the AI APIs directly. No SaaS tax." — @evinjohnn (Regarding the open-source alternative Natively)

For Indie Hackers

Tech Stack

How the Core Feature Works

GhostDesk’s "invisibility" relies on the native Windows API SetWindowDisplayAffinity(WDA_EXCLUDEFROMCAPTURE). This API works at the DWM (Desktop Window Manager) level. DWM sits between applications and the display hardware; when a window is flagged this way, DWM skips it in all screen capture paths. Whether it's BitBlt, DXGI Desktop Duplication, or Windows Graphics Capture, they simply cannot see the window content.

In short: It’s not some proprietary black magic; Windows provides this "window invisibility" feature natively, and GhostDesk simply implements it correctly.

For audio, it uses Deepgram Nova-3 for real-time speech-to-text (supporting two-way conversation), then feeds the transcript to an LLM (Llama or GPT-4o) to stream back suggested answers.

Open Source Status

• GhostDesk is closed-source.
• Similar Open Source Projects:
  • Natively — The most popular open-source Cluely alternative, 7000+ users, 11.2k+ GitHub clones.
  • GhostLayer — An invisible overlay for macOS, built with Flutter + Swift.
  • Pluely — An open-source alternative 27x lighter than Cluely.
  • WindowCaptureHider — A pure DLL that can make any window invisible.
• Build Difficulty: Medium-Low. The core invisibility is a single Windows API call. Speech-to-text and LLMs have mature APIs. A full-stack dev could build an MVP in 2-4 weeks.

Business Model

• Monetization: Subscription + Lifetime buy-in (dual-track).
• Distribution: Official site + Whop (with affiliate commissions).
• Free Strategy: Completely free during the launch phase to acquire users, then converting to paid.
• Pricing Strategy: All plans offer identical features, differing only in duration—this lowers the user's decision friction.

Giant Risk

Medium-High. Microsoft could add similar features to Copilot at any time (after all, SetWindowDisplayAffinity is their own API). However, a tech giant is unlikely to market an "invisible interview assistant" due to ethical concerns. The real risk comes from direct competitors like Cluely, which raised $15M from a16z.

For Product Managers

Pain Point Analysis

The Problem: Users want AI assistance during video calls/interviews but are afraid that switching tabs or sharing their screen will expose them.

How much does it hurt?:

• Technical Interviews → High pain. One offer can mean a salary difference of tens of thousands of dollars.
• Sales Calls → Moderate pain. Handling objections in real-time requires quick knowledge retrieval.
• Daily Meetings → Low pain. Useful, but not a "must-have."

For Tech Bloggers

Founder Story

The founder's identity is currently unconfirmed. The official contact is [email protected]. While there is Maker info on ProductHunt, a quick search didn't yield a bio. Given the product's polish, it's likely an experienced indie dev or a small team.

The Niche Story is Better: The "instigator" of this niche is Cluely co-founder Chungin "Roy" Lee. While at Columbia University, he built a tool called "Interview Coder" to cheat his way into an Amazon tech interview. After being expelled, instead of stopping, he raised a $5.3M seed round, followed by a $15M Series A led by a16z. Valuation: $120M.

Controversy & Discussion Angles

1. The Ethical Gray Area: GhostDesk’s disclaimer is clear: "You are solely responsible for how you use it." But when the core selling point is "invisibility," the disclaimer feels a bit like burying one's head in the sand.
2. Open Source vs. Closed Source: Natively's developer is actively promoting the open-source alternative on Twitter, emphasizing "No SaaS tax."
3. Corporate Pushback: Google, Cisco, and McKinsey have already increased in-person interviews to combat AI cheating.
4. Cluely Data Leak: In mid-2025, Cluely leaked data for 83,000 users—a privacy tool suffering a privacy disaster.

Hype Metrics

• PH Ranking: 101 votes (Moderate hype, very new product).
• Twitter Buzz: GhostDesk itself is quiet, but the "Cluely alternative" topic is constantly trending.
• Niche Heat: Extremely high. Cluely’s $120M valuation + multiple competitors prove the market is in an explosion phase.

Content Suggestions

• Angle: "In 2026, 'Invisible AI' tools are everywhere—what does this mean for the future of work?"
• Trend Jacking: Reference these tools whenever a major company announces a "return to in-person interviews."

For Early Adopters

Pricing Analysis

Key Info: All plans have identical features. The only difference between free and paid is the quality of the AI model.

• Drivers: Normalization of remote interviews + LLM capability explosion + hyper-competitive job market.

Competitive Landscape

Timing Analysis

Why now?:

1. Cluely proved the demand in 2025 ($3M ARR).
2. Open-source LLMs (Llama 3.3/4) + Groq inference make free products viable.
3. Remote interviews remain the standard in 2026, despite some corporate pushback.

Tech Maturity: High. The Windows SetWindowDisplayAffinity API is a mature system-level feature. Deepgram/OpenAI APIs are stable.

Market Readiness: High, but with an ethical ceiling. a16z’s investment in Cluely shows VC validation, but the "cheating" stigma creates a hidden growth cap.

Team Background

Unconfirmed. Likely an indie developer or small team. No funding information disclosed.

Funding Status

• GhostDesk: No funding found.
• Cluely Benchmark: If GhostDesk can replicate user growth with its lower price point and zero-config experience, it has the potential to become the go-to budget alternative to Cluely.

Conclusion

GhostDesk is the most accessible entry point into the "Invisible AI" space—free, zero-config, and ready in a minute. However, it faces two core challenges: its Windows-only nature limits the user pool, and the ethical controversy of the entire niche hangs like a Sword of Damocles over its growth.
