In a job market where the technical bar is rising daily, choosing the right AI copilot isn't just an advantage—it's the margin between an offer and a rejection. We compare the three leading platforms in 2025.
The year 2025 marks a turning point for professional growth. As AI continues to redefine the interview process, candidates for high-tier roles—from FAANG engineers to executive product leaders—are leveraging AI Interview Assistants to perform at their peak.
The Critical Need for Stealth
Before diving into specific tools, we must address the most important feature: detection prevention. Whether it's Zoom, Google Meet, or proprietary proctoring software, standard screen-capture tools are designed to see everything.
A true interview assistant must operate as a stealth overlay. This technology renders text directly to your screen's display buffer in a way that is invisible to the screen-sharing process. Without this, using AI during an interview is a massive risk.
Cluely AI (Cluly)
Cluely AI, frequently searched as Cluly, is widely regarded as the pioneer of the invisible overlay. Its focus is singular: providing a rock-solid, undetectable experience for technical coding rounds.
What we like
- Superior invisibility on Zoom & Teams.
- Highly accurate algorithm suggestions.
- Minimal distracting UI elements.
What we don't
- Expensive tier-based pricing.
- Lacks robust behavioral coaching.
- Not optimized for non-technical roles.
LockedIn AI
LockedIn AI positions itself as the more "comprehensive" copilot. It doesn't just show up for the interview; it aims to be your coach throughout the entire preparation phase.
What we like
- Excellent company-specific question banks.
- Strong resume and JD parsing tools.
- Decent voice-to-text accuracy.
What we don't
- Heavier performance footprint on systems.
- UI can lead to "information overload."
- Not as reliably stealthy as its competitors.

The Verdict for 2025
If your goal is to have the most comprehensive, persiapan platform with a massive question bank, LockedIn AI is a strong contender. If you only care about technical coding rounds and money is no object, Cluely still holds weight.
However, for the candidate who needs instant reactivity, 100% reliable stealth, and an assistant that helps win both the technical and behavioral rounds, Feret is the definitive choice.

Frequently Asked Questions
Can Cluely AI be detected on Zoom?
While Cluely is highly advanced, no tool is perfect. However, its GDI overlay method is specifically designed to remain invisible to Zoom's standard screen-capture protocols.
Is LockedIn AI better than Cluly?
It depends on your needs. LockedIn offers more "offline" preparation features, while Cluly focuses more on the "online" stealth aspect of the live interview.
Is Feret undetectable during interviews?
Yes. Feret utilizes low-level graphics injection which bypasses all commercial screen-sharing and recording software used by Zoom, Teams, and Meet.
Does Feret help with coding?
Absolutely. Feret provides real-time logic suggestions, time complexity analysis, and edge-case reminders for Python, Java, C++, JavaScript, and 30+ other languages.
