If you've been researching AI interview tools, you've probably narrowed it down to two: Cluely - the well-known, well-funded incumbent - and Acemode - the newer underground entrant.

I'm going to give you a brutally honest comparison. Full disclosure: this post is on the Acemode blog, so I'm clearly biased. But I'm going to point out where Cluely is genuinely better, where it's worse, and what actually matters for your situation.

Quick verdict if you don't want to read the whole post

The honest answer

Both work. Both are invisible to screen sharing. The differences come down to price ($29 once vs $20-50/mo subscription), brand visibility (Cluely is famous, Acemode is underground), and specialization (Acemode is interview-tuned, Cluely is more general-purpose).

The architectural similarity nobody mentions

Before diving into differences, here's the thing both products got right: they both use the same underlying OS-level screen capture protection.

On macOS, both use the setContentProtection API which maps to kCGWindowSharingNone in CoreGraphics. On Windows, both use SetWindowDisplayAffinity(WDA_EXCLUDEFROMCAPTURE). This is the same hardware-level mechanism that lets Zoom hide its own UI from recordings, or that DRM-protected video uses to prevent screenshots.

Either tool's invisibility is a function of the operating system, not the application. Neither tool has a "better" invisibility - they have the same invisibility.

This matters because most comparison content tries to sell one tool's "superior protection" as a differentiator. It's not. Both work for the same reason. Make your decision on other factors.

Pricing - the most important difference

Cluely's pricing model

At the time of this writing, Cluely uses a subscription model with monthly tiers. Pricing varies but typically lands in the $20-50/month range depending on which tier and features you choose.

For a typical job seeker doing a 6-week interview cycle, that's $30-75 for the duration of their search. If you take a month off and come back, you pay again.

Acemode's pricing

One-time payment of $29. No subscription. No monthly fees. The license is yours forever, including all future updates.

For the same 6-week interview cycle, that's $29 total. About 60% cheaper than Cluely on the lowest tier.

If you're between jobs again in 2 years, you still own it. Cluely users would need to resubscribe.

The real economics

The math is straightforward. If your interview process takes longer than ~6 weeks, Acemode is cheaper. If you have any expectation of needing the tool again in the future (career switch, layoff, role change), Acemode is dramatically cheaper.

If you have an interview tomorrow and you'll never need this tool again, Cluely's monthly tier is competitive - but you should also know there's a 3-session free trial of Acemode that might be enough for your single use case.

Brand visibility and detection risk

This is where the comparison gets nuanced.

Cluely is famous

Cluely has been featured in TechCrunch, Forbes, the Verge, and dozens of YouTube videos. The founder is well-known on Twitter. The company is well-funded.

This is great for credibility - but it's a real liability for users. Some interviewers now know Cluely exists. Some recruiters specifically check for it. Hiring managers occasionally mention it in interview-prep articles as "watch out for this."

The exact thing that makes Cluely a successful business - visibility - is what makes it slightly more risky for the end user. The famous tool is the one being looked for.

Acemode is underground

Acemode is newer and intentionally less visible. No press articles. No viral founder Twitter. Distribution is through word of mouth in developer communities.

This is bad for marketing - but it's actually good for users. An interviewer who hasn't heard of a tool isn't watching for it. An anti-cheating policy that mentions Cluely by name doesn't mention Acemode.

Underground status is a feature, not a bug. The day Acemode gets a TechCrunch article is the day this advantage starts to erode. (We're not in a hurry.)

Feature comparison

Where Cluely is better

Audio listening. Cluely can transcribe audio from your interview in real-time, parse it, and generate responses. This is genuinely impressive engineering. Acemode has voice input (you press Alt+R and speak the question yourself) but doesn't passively listen to interviewer audio.

UI polish. Cluely is well-funded and it shows. The UI is more polished. Animations are smoother. The onboarding is professional.

Larger user base. More users means more edge cases have been encountered and fixed. Cluely has had time to deal with weird scenarios that Acemode hasn't seen yet.

Where Acemode is better

Price. Already covered. $29 once vs subscription.

Interview-specific tuning. Acemode's responses are formatted specifically for technical interviews. Coding answers have the structure: Approach → Code → Complexity → Edge Cases. System design answers have the structure: Clarifying Questions → Problem Framing → HLD → LLD → Scaling → Trade-offs. This is faster than re-prompting a general-purpose AI for the right format.

Resume integration. Upload your resume once and behavioral answers are personalized to your actual experience. Cluely doesn't have this as a first-class feature.

Reads platforms with copy-paste disabled. Both tools read pixels rather than DOM, but Acemode is specifically optimized for this case. Tested on CoderPad, HackerRank, CodeSignal, and 20+ company-custom editors.

Lower visibility. Underground equals less detected.

Free trial. 3 complete interview sessions free, no credit card. Cluely has a trial too but the experience varies.

What about feature parity on the basics?

Both tools have:

For basic use cases, they're functionally equivalent.

The two-tool strategy nobody mentions

Some users use both. Cluely's audio transcription as a passive listener, Acemode's structured screen-reading for the actual problem-solving. Total cost: ~$50-80 for a job search depending on Cluely's tier. Higher than either alone, but the combination covers more interview formats.

Most people don't need both. But it's an option worth knowing exists.

What I'd actually do in your shoes

Try Acemode first. The 3 free sessions cost you nothing and tell you whether the category is for you at all. Most people who try it for one real interview end up paying.

If after the trial you specifically want passive audio transcription that Acemode doesn't have, then look at Cluely. Most don't end up needing it.

If you're in a corporate setting where someone might be looking specifically for Cluely (some larger companies have started flagging it), the underground choice is the safer one anyway.

What I won't do - claim Acemode is "better" in some absolute sense

It's not. It's different. The right answer depends on your situation, your budget, and what you value.

Cluely is a legitimately well-built product. The team behind it ships fast and has a lot of resources. If they had a one-time pricing tier, this comparison would be much closer.

What I will say is this: at $29 vs $20-50/month for similar core functionality, Acemode is the dramatically better economic choice for the vast majority of users. That's not bias. That's basic math.

If price is no object and you specifically want the audio transcription feature, Cluely. Otherwise, Acemode.
