Beyz AI vs Cluely: Honest 2026 Comparison

Both are stealth-first, but Beyz AI is the better-value interview specialist: an invisible desktop assistant with 230K+ users, real-time answer prompts, a coding assistant with logic and complexity hints, role-specific cheat sheets, and 10+ languages with translation — at roughly $24.99–$49.99/month. Cluely has the louder brand and works across any meeting, but its screen-share undetectability sits behind a $149.99/month tier, it disclosed a 2025 data breach affecting ~83,000 users, and independent testing measured 5–10 second latency against its advertised 300ms. For interviews specifically, Beyz gives you more for roughly a third of the price.

Price: The Clearest Gap

This is the single biggest difference. Cluely has a free Starter tier and a $19.99/month Pro plan, but the screen-share undetectability most candidates actually want lives in the $149.99/month Pro + Undetectability tier. Beyz AI includes its invisible desktop overlay in plans around $24.99–$49.99/month. For interview use, you are paying roughly three times more for Cluely to get the same core capability — plus Cluely's overlay is general-purpose rather than tuned for interviews.

Trust and Detection

Both render on-screen overlays hidden from normal screen recording, so the recruiter-side detection ecosystem (Sherlock AI, FabricHQ, CoderPad's keystroke flags) is the relevant risk for either. The differentiator is track record: Cluely disclosed a 2025 data breach affecting ~83,000 users — a real consideration when you are uploading a resume and streaming interview audio — and independent testing has measured 5–10 second real-world latency against its 300ms claim. Beyz has no comparable reported incident and a 230K+ user base.

Multi-Language Interviews

If you interview in a language other than English, Beyz AI is the stronger pick: 10+ languages with real-time translation is a core feature rather than an afterthought. Cluely supports multiple languages but is built primarily around English-language meetings.

The Third Option

Both are paid and both render on-screen. Interview Sidekick gives you a native off-screen overlay (a different detection profile entirely), plus 10,000+ real interview questions and AI-graded mock interviews for the prep neither tool really covers — on a genuine free tier, no credit card.

Frequently Asked Questions

Is Beyz AI or Cluely better for interviews?

For interviews specifically, Beyz AI offers better value — an invisible desktop assistant built for interviews with a coding helper, role-specific cheat sheets, and 10+ languages at roughly $24.99–$49.99/month. Cluely is a general meeting assistant with a bigger brand, but its undetectable tier costs $149.99/month and it has no interview prep tooling.

Why is Cluely so much more expensive than Beyz AI?

Cluely gates screen-share undetectability behind its top Pro + Undetectability tier at $149.99/month, while Beyz includes its invisible overlay in plans around $24.99–$49.99. You are effectively paying about 3x for the same core capability, plus Cluely's general-purpose scope across any meeting rather than interview-specific tuning.

Is Beyz AI actually undetectable?

Beyz runs as a desktop app whose overlay is hidden from screen recording on Zoom, Meet and Teams — the same architecture as Cluely and other stealth tools. It still renders on your screen, so recruiter-side detection products target that surface. No tool is guaranteed undetectable; rehearse on a screen-share before a real interview.

What is the cheapest good alternative to both?

Interview Sidekick has a genuine free tier with no credit card, combining a real-time copilot and coding support with 10,000+ practice questions and AI mock interviews — plus a native off-screen overlay rather than an on-screen one.
