COMPARISON
Interview Helpers vs Cluely
Cluely became known for its bold "cheat on everything" positioning across sales, interviews, exams, and everyday tasks. Interview Helpers is narrower — a Windows-native stealth overlay purpose-built for tech interviews specifically.
Different products for different needs. If your workflow is a mix of contexts and you want one tool for all of them, Cluely covers more surface area. If your problem is specifically technical interviews on Windows, Interview Helpers has more depth in that use case: dedicated System Design mode with rendered Mermaid diagrams, four AI models to switch between, and native OS-level stealth.
Interview Helpers wins 5 of 10 feature categories, Cluely wins 2, the rest are a tie. Updated 2026-08-29.

Which should you pick?
Pick Interview Helpers if tech interviews are your primary need
Windows-native stealth via OS capture-exclusion, dedicated System Design mode with rendered Mermaid diagrams, 4-way model switching, and a LeetCode/system-design/behavioral toolkit that's been tuned end-to-end.
Pick Cluely if you want one general tool for many contexts
Cluely's positioning is broader — sales calls, interviews, exams, general computer use. If a single tool for many contexts is more valuable to you than depth in one, Cluely fits that pattern.
Frequently asked questions
What is the difference between Interview Helpers and Cluely?
Interview Helpers is a Windows-native stealth overlay built specifically for tech interviews — coding rounds, system design, and behavioral. Cluely is a broader real-time answer product with a "cheat on everything" positioning. If you only need tech interview support and you're on Windows, Interview Helpers is more focused and deeper on that use case.
Is Interview Helpers a Cluely alternative?
For tech interviews specifically, yes — Interview Helpers is arguably the more focused tool: dedicated System Design mode with Mermaid diagrams, 4-way model switching, Windows-native stealth via the OS capture-exclusion flag. If you want a product that also helps in sales calls, exams, or general everyday tasks, Cluely covers more surface area.
Which is better for system design?
Interview Helpers has a dedicated System Design mode that returns rendered Mermaid flowcharts, sequence diagrams, and ER models inline as SVG. Cluely returns text-form design answers.
How does the stealth compare?
On Windows, Interview Helpers uses the OS-native WDA_EXCLUDEFROMCAPTURE flag so the overlay is invisible to Zoom, Google Meet, Microsoft Teams, Snipping Tool, and OBS. Cluely is more macOS-oriented; on Windows, our OS-level flag is materially stronger.
