GeekBye vs Cluely: Which One Actually Fits an Interview?

If you have searched for a real-time AI assistant in the last year, you have seen Cluely. It is the loudest brand in the category, and its marketing does not do subtlety.

This is not a hit piece. Cluely does real things well. But the two products are built around different bets, and if you are specifically preparing for interviews, the difference matters more than the feature lists suggest.

The short version

Cluely is a general-purpose real-time assistant. Meetings, sales calls, support calls, interviews — one assistant across all of it. Its pitch is breadth.

GeekBye is a native desktop assistant built around two moments: a question on your screen, and a conversation in your ear. Screenshot something, get an answer. Turn on Listen, get live transcription of both sides. Its pitch is depth on the interview.

Both put an answer in front of you while you are still on the call. Where they split is what you pay for, and how invisible you actually are.

The undetectability difference

This is the part worth understanding before you spend anything.

Cluely sells undetectability as a tier. Its standard Pro plan sits around $19.99/month; the plan that adds undetectability is priced at $149.99/month on monthly billing (about $44.99/month billed annually) at the time of writing. That is roughly 7.5× on monthly billing, for a capability most people assumed they were already buying.

GeekBye does not have an undetectability tier, because it is not an upsell. Screen-share invisibility ships on every plan, including the free one. The free plan gives you limited AI responses — it does not give you a watered-down, visible version of the app.

That is a product decision, not a discount. Invisibility is the reason people install a tool like this. Charging separately for it means the cheaper tier is, for the main use case, not really a working product.

	GeekBye	Cluely
Invisible during screen share	Every plan, free included	Highest tier only
Free plan	Yes, with invisibility	Limited
Entry paid price	See pricing	~$19.99/mo (no undetectability)
Undetectable paid price	Same as any paid plan	$149.99/mo monthly, ~$44.99/mo annually
Primary focus	Interviews and meetings	Broad: meetings, sales, interviews
Form factor	Native desktop overlay	Assistant across the desktop and browser

How the invisibility actually works

GeekBye is a native desktop app, and the window it draws is marked as protected content at the operating-system level. macOS excludes it from screen capture; Windows blocks display capture on it.

The practical result: Zoom, Google Meet, Microsoft Teams, Slack huddles, OBS, QuickTime, and your own screenshot key all capture your screen with GeekBye simply absent. There is no layer for a meeting app to find and filter, because the frames it receives never contained the window.

This is also why the form factor matters. A browser-centric assistant has to solve invisibility inside a browser tab, which is a much weaker position — the browser window is exactly the thing you are sharing. A separate desktop overlay sidesteps the problem instead of fighting it.

If you want the mechanics rather than the summary, we wrote them up in how undetectable interview assistants actually work, and the feature page is at /undetectability.

Where Cluely is the better choice

Being honest about this makes the rest of the post worth reading.

• You want one assistant for everything. If your week is sales calls, standups, customer calls, and the occasional interview, Cluely's breadth is a genuine advantage. GeekBye is narrower on purpose.
• You are not price-sensitive and want the biggest brand. Cluely has more people using it, more content about it, and a larger surface of integrations and community answers.
• You want prep tooling bundled with live help. Cluely has invested in a wider surrounding product than a focused overlay does.

Where GeekBye is the better choice

• The interview is what matters. Screenshot a coding problem with one key, ask a follow-up in chat, start Listen for live transcription. Three shortcuts cover almost everything, which is the entire point when your hands are shaking.
• You do not want to pay a premium to stay hidden. Same invisibility on the free plan as on the paid ones.
• You care where your screen goes. Screenshots are processed on-device first — text is extracted locally before anything is sent for an answer.
• You want no browser extension. Nothing is installed into your browser, and nothing has access to your meeting account, so there is nothing for an admin console to list.

What neither of them does

Undetectability means one specific thing: the tool does not appear in captured frames. It does not mean you are undetectable.

• It does not hide your eyes moving to a different part of the screen.
• It does not defeat a second camera, a phone pointed at your desk, or a person in the room.
• It does not help inside a locked-down proctoring environment that takes over the machine, or on a company-managed laptop running monitoring agents.
• It is not permission. Follow the rules of whatever process you are in.

Any vendor implying otherwise is selling you a feeling, not a feature.

How to decide in ten minutes

1. Install GeekBye on the free plan. It costs nothing and already includes invisibility.
2. Start a test meeting with yourself and share your whole screen. Check the self-preview.
3. Run one real practice question end to end — screenshot, answer, follow-up.
4. If the workflow fits and the invisibility holds, you have your answer without spending anything.

That test takes less time than reading a pricing page, and it tells you more.
