GhOst vs Cluely — short answer
Cluely is built around the promise of an invisible copilot: a fast overlay that can help during calls, meetings, and interviews without appearing in a normal screen share. GhOst is narrower but deeper: a desktop AI interview assistant focused on technical interviews, online assessments, and platform-specific stealth.
If your entire interview funnel is a friendly Zoom call and you want a simple overlay, Cluely is a recognizable option. If your funnel includes HackerRank, CodeSignal, Codility, CoderPad, system design, behavioral loops, or stricter screen recording, GhOst is the stronger choice because it combines process-level invisibility, multi-model AI, voice delivery, and assessment-specific workflows.
What each product is optimized for
Cluely is a general-purpose real-time copilot. That makes it flexible: the same product can be used for meetings, calls, sales demos, and interviews. The tradeoff is that interview depth is only one use case inside a broader product.
GhOst is purpose-built for interview execution. The product experience is organized around coding rounds, behavioral answer frameworks, system design prompts, and proctored online assessments. Instead of only showing a suggested answer, GhOst tries to help the candidate deliver the answer naturally, choose the right model, and avoid platform-specific visibility issues.

Stealth: overlay invisibility vs process-level invisibility
The biggest difference is not the headline claim that both products are "invisible." The difference is where invisibility happens.
Cluely's overlay model is useful when the main risk is ordinary screen-share capture. If the interviewer is watching your shared Chrome window, a hidden overlay can be enough because it does not appear in the shared video stream.
GhOst's Phantom Mode is designed for a broader threat model: screen-share, session recording, process enumeration, overlay-window scanning, and assessment environments that monitor tab focus or app switching. That extra depth matters for CodeSignal and Codility style assessments where the platform is not just looking at pixels; it can also observe browser state, device permissions, and suspicious workflow changes.
What the interviewer sees
| Scenario | GhOst | Cluely |
|---|---|---|
| Zoom screen share | Only the shared interview window | Usually only the shared interview window |
| Full-screen coding round | Answer stream remains hidden from capture | Overlay hiding is the main protection |
| Proctored browser assessment | Designed around process and recording invisibility | Less ideal if overlay or external app scans are active |
| Live interviewer asks for reasoning | Incremental hints and voice phrasing help natural delivery | Candidate still has to translate text into speech |
AI quality and model control
Interview performance depends on the model, but it also depends on routing. Coding, system design, and behavioral interviews reward different model strengths. A model that writes clean code may not produce the most concise spoken behavioral answer; a model that explains well may not handle a tricky dynamic programming edge case under time pressure.
GhOst lets candidates choose from OpenAI, Anthropic, and Google providers and bring their own API keys. This gives three practical advantages:
- Specialization: use a coding-strong model for algorithms and a reasoning-strong model for system design.
- Resilience: if one provider slows down, switch providers before the interview.
- Cost control: free use is possible with your own keys, so you do not have to buy a subscription for light usage.
Coding interviews: who handles the actual round better?
Cluely can suggest answers, but GhOst is structured around the pattern of a technical interview: detect the problem, explain the brute force, produce an optimal solution, call out complexity, and give concise speaking notes. The difference shows up when the interviewer asks "why this approach?" or "what happens with duplicate inputs?"
GhOst is stronger for coding because it includes:
- Time and space complexity callouts
- Edge-case checklists
- Multi-language solutions across 91+ programming languages
- Incremental hint mode so the candidate does not appear to instantly read a full solution
- Platform-specific flows for HackerRank, CodeSignal, Codility, CoderPad, and LeetCode
Behavioral and system design rounds
Most comparison pages focus only on coding, but the offer is usually won or lost across the full loop. Behavioral interviews require personal story structure, and system design requires tradeoffs rather than a single correct answer.
GhOst has framework-aware behavioral prompting for STAR, CAR, SOAR, Amazon Leadership Principles, Google Googliness, and Meta values. For system design, it prioritizes interview-ready architecture: functional requirements, non-functional requirements, APIs, data model, scaling bottlenecks, caching, queues, observability, and tradeoffs. Cluely can still help, but its broader copilot positioning makes those interview-specific paths less central.
Pricing and total cost
The monthly sticker price is only part of the decision. Candidates usually need an interview assistant for one of three windows: a two-week job search sprint, a three-month active funnel, or a longer FAANG preparation cycle.
| Usage pattern | Best fit | Why |
|---|---|---|
| One or two calls | GhOst credit pack or free own-key mode | No need to commit to a subscription |
| Several interview loops | GhOst monthly | More interview-specific coverage per dollar |
| Long search cycle | GhOst annual | Lower effective monthly cost with full feature access |
| Non-interview meetings too | Cluely | General copilot utility outside hiring workflows |
Where Cluely is genuinely better
Cluely has a simpler story: invisible copilot for many contexts. If you want one tool for sales calls, meetings, notes, and casual interviews, that breadth is useful. The onboarding may also feel simpler because there are fewer interview-specific decisions to make.
Where GhOst is decisively better
- High-stakes technical interviews: coding, system design, and behavioral rounds are first-class workflows.
- Proctored assessments: Phantom Mode is designed around more than normal screen-share hiding.
- Model flexibility: switch between frontier providers and bring your own key.
- Natural delivery: voice synthesis and incremental hints make answers easier to speak.
- Platform coverage: broader support for coding platforms beyond meeting apps.
Verdict
Pick Cluely if you want a general invisible copilot for meetings and lower-stakes calls.
Pick GhOst if the goal is to pass technical interviews, handle proctored coding assessments, answer system design follow-ups, and deliver responses naturally without relying on a visible text overlay.
For most candidates comparing these two specifically for interviews, GhOst wins on stealth depth, AI flexibility, platform coverage, and interview-specific workflows.
