When does launch pricing end?

When we hit 1,000 paying customers. There's no countdown date. The live count is shown on the pricing page and updates as people join. Whenever it crosses 1,000, founder pricing closes for new sign-ups; anyone already subscribed keeps their rate.

What are the system requirements?

Windows: Windows 10 (build 1909 or later) or Windows 11 on x64. macOS: macOS 11 (Big Sur) or later on Apple Silicon or Intel. The Windows driver is Microsoft-attestation-signed for supported Windows builds; the macOS app is Developer ID signed and notarized.

Does it work in a VM or on Boot Camp?

VMs are not recommended. The Windows protection layer depends on direct hardware access that virtualization layers (Hyper-V, VMware, Parallels) abstract or mediate, and VM-detection vectors fire harder. Boot Camp can run the Windows build on supported Intel Macs, but the native macOS build supports both Apple Silicon and Intel.

How do I install it on macOS?

Download Aceloop.dmg on a Mac running macOS 11 or later, open the DMG, drag Aceloop to Applications, then launch it from Applications. macOS may ask for Accessibility, Screen Recording, and Microphone permissions the first time you enable workflows that need them.

Yes: within the surface we defend, and honestly outside it. Inside our surface (browser content scripts, screen-share capture, process enumeration, automated proctor-vendor detection) the four-layer kernel architecture beats every documented detection vector. Outside our surface (a human watching over your shoulder, an interviewer asking you to walk through your reasoning, audio on the call) no software answer exists, and we say so. On data: we don't store your interview problem, your code, or your test output. The kernel driver is signed with our EV cert and goes through Microsoft's WHQL pipeline. Full threat model, data stance, and attestation chain at https://aceloop.ai/security.

Do I need to copy and paste the problem?

No. Press the hotkey and Aceloop reads the problem statement, your code, and the terminal output straight from the platform's process memory at the Windows kernel. No screenshots. No OCR. No clipboard. The bytes are already in RAM, so we just take them. Other tools spin up a screen capture pipeline and feed it to OCR. We bypass the screen entirely.

What makes the security approach different from competitors?

Most tools pick one trick and pray. We stack four independent layers: kernel-level display filtering, process concealment, window enumeration blocking, and detection-query spoofing. The strategy goes past the code. We defend one operating system instead of three, keep distribution tight to limit targeting, and test every release against the newest proctor builds before it goes out.

How do other AI tools get caught?

Three ways, all visible to a browser-side proctor. One: keystroke logging. Their hotkey is a plain keydown event the browser sees. Two: lost window focus. Their overlay paints over the coding platform and the proctor flags the gap. Three: memory scan. Their process name reads straight out of the task list. If a browser tab can see a tool's hotkey, so can CoderPad, HackerRank, and CodeSignal. They run at the same or higher privilege on your machine. Aceloop intercepts hotkeys at the kernel before the browser sees them, strips its overlay from the display pipeline before any capture path, and hides its process from enumeration. It doesn't trigger a single vector on the page that lights up every other tool.

Does Aceloop work against CoderPad Enterprise?

Yes. CoderPad Enterprise is the proctoring stack where competitors most often fail: its content script enumerates window visibility flags, hooks screen-capture differential analysis, and pairs with Amazon Chime for call-side checks. Aceloop's kernel-level display-pipeline strip and process concealment defeat the relevant vectors. The full breakdown of what CoderPad Enterprise actually checks for, and which of our four stealth layers answers each check, is in the dedicated post.

Is Aceloop visible to anti-cheat tools like BattlEye or EasyAntiCheat?

Coding-interview platforms don't ship game-grade anti-cheat. BattlEye and EasyAntiCheat live inside specific games (Fortnite, Apex, Tarkov), not in CoderPad or HackerRank, and they don't run on a candidate's machine during a coding interview. If you happen to be running a BattlEye-protected game in the background, close it before the round to avoid driver-load conflicts. The four stealth layers Aceloop ships use the same kind of kernel construct anti-cheat uses, applied in the opposite direction.

What AI models are used?

Frontier models for the heavy reasoning, fast models for the routing layer. We swap the exact stack as new releases ship. The bar stays fixed: best quality and lowest latency you can get inside a live interview.

Can I customize the prompt or model?

Not directly. The prompt and model selection are managed by the application based on the workflow (Solve, Debug, Optimize) and the platform context. The reason is interview latency: a candidate fiddling with prompt wording inside a 45-minute round burns time better spent on the actual problem. The internal prompt rotates with model releases; we tune it once for everyone instead of asking each user to tune it for themselves.

What is Reasoning Mode?

Reasoning Mode gives the model a deeper, agent-style orchestration pass: it plans, checks, and refines before the answer streams back. Switch it on in Settings when the round stops being routine; expect a few extra seconds of latency in exchange for stronger answers on the hardest problems.

Study Mode turns the system design graph you use in the interview into a practice surface. Click any node, edge, or assumption to drill into the tradeoff, the scaling math, the failure mode, and the wording a strong candidate would use to defend it.

Can I prepare with Aceloop for a coding round?

Yes. The demos at https://aceloop.ai/demo and the Solve/Debug/Optimize workflows run against practice problems exactly the same way they run against live interview problems. Open a LeetCode or HackerRank problem, hit Alt+Enter, work through the iteration. Most buyers spend the first week using Aceloop as a prep tool before they ever take it into a real round. For a structured 8-week prep arc, see the FAANG interview prep guide.

How do I switch between monthly and yearly?

Open Manage Billing from the Subscription tab to update your card or cancel. To move between monthly and yearly, cancel the current plan (you keep access through the end of the period you've already paid for) and start the other from the pricing page. Yearly locks in the 75% saving vs paying month to month.

What happens if my subscription lapses?

On a failed billing attempt Stripe enters its smart-retry window (3 attempts over ~14 days). If all three fail, the subscription cancels and the license becomes inactive. The desktop app stops accepting hotkeys until you reactivate. Reactivation is one click in the Subscription tab; pick monthly or yearly, the license re-binds to your current device. We don't punish lapsed customers; payment retry is just how Stripe handles a card decline.

Why does the product feel low-profile compared with bigger brands?

Because the loud tools in this category get targeted first. The bigger the marketing footprint, the faster proctoring vendors fingerprint the binary, the build, and the install pattern. We grow through referrals, keep the rollout tight, and treat a quiet brand as a piece of the protection stack.

Using AI assistance during a coding interview is a question of platform terms of service and the company's interview policy, not criminal law. There's no statute that addresses an AI overlay on a candidate's machine. Most coding-interview platforms ban it in their terms; some companies explicitly allow AI in specific rounds in 2026. Whether to use it is the candidate's decision and the candidate's risk. We build the tool; the ethics are yours.

Are you ex-FAANG engineers?

We don't say. The brand-quiet posture extends to founder background: naming current or former employers attaches the binary to a person, which attaches it to a fingerprint, which attaches it to the proctoring industry's targeting list. The product judgment is in the product: the four kernel layers, the memory-read input path, the live key-event viewer anyone can run before they buy. Pedigree is not the question; what the binary does in your interview is.

Yes. Live since 2026 with Stripe checkout, an EV-cert-signed kernel driver, and continuous releases tracked at https://aceloop.ai/changelog. The brand stays low-profile by design (loud stealth tools get fingerprinted faster), so there isn't a marketing footprint to validate it the way you'd validate a typical SaaS. Concrete signals: the in-browser key-event viewer runs today, the kernel driver's cert chain + per-release SHA256 is publishable, and the Free tier ships three full problems with no credit card so you can verify the binary works against your actual coding platform before paying. Verify the binary independently before installing. Don't trust adjectives; trust mechanics.

Are there Aceloop reviews?

Yes. Reviews from users are published on the homepage alongside the running average rating, and they name the companies where those users report passing rounds. The unfiltered conversation lives in the Discord, where you can ask candidates who ran Aceloop on their own loops, and external mentions we've found are aggregated at https://aceloop.ai/coverage.

What does Reddit say about Aceloop?

Reddit threads in r/cscareerquestions, r/leetcode, and r/csMajors discuss AI interview tools regularly. Our name surfaces in comparison threads (vs Interview Coder, Cluely, LockedIn AI). The consistent pattern in those threads is competitors getting caught on CoderPad Enterprise, Apple loops, and Amazon Chime; Aceloop doesn't appear in those "got caught" reports. We don't astroturf, sponsor, or moderate Reddit discussion. The https://aceloop.ai/coverage page aggregates external mentions we've found if you want a starting set.

No. Real product, ships continuously (see https://aceloop.ai/changelog), runs through Stripe, and licenses bind to a hashed hardware ID rather than your real name. All sales are final (see https://aceloop.ai/refund-policy). The Free tier exists specifically so you can run three full problems against your real coding platform before you ever pay. The "scam" pattern in this category usually involves fake stealth checks, no working binary, or refusing to let you test before purchase. If you're skeptical, run our key-event viewer against any AI tool first, exhaust the Free tier on your actual platform, and verify the kernel driver's signature chain against the published SHA256 documented in https://aceloop.ai/security.

How long has Aceloop been around?

Public launch was May 2026: the kernel-level overlay, the in-browser key-event viewer, and the four-stealth-layers architecture all shipped together. Engineering on the Windows kernel driver predates the public launch by an internal R&D cycle (months, not years, but real). The blog launched alongside the product surface. Track shipped releases in https://aceloop.ai/changelog. Every kernel update, detection-vector patch, and site-architecture change since launch is logged with date, scope, and commit hash where applicable.

After the round, this is what they say.

Outcome reports from users: what worked in the round, in their words.

“Two phone screens and an onsite with the overlay running. The part that mattered was Debug on my own half-broken solution while I talked through the failing case. It found the off-by-one before the interviewer did.”

DKDaniel K. · L4 offer · Google

“I type fast and panic faster. Having the approach and complexity laid out before I said anything out loud meant I stopped narrating garbage. Passed the OA and both coding rounds.”

PSPriya S. · SWE II offer · Amazon

“Optimize turned my brute-force into the heap solution and explained why in words I could actually repeat. That's the difference between using AI and learning from it mid-round.”

SMSofia M. · SWE offer · Microsoft

“Used the free three problems on a CodeSignal practice set, paid the same day. The ghost completions inside the editor are the feature: no second window, nothing to paste.”

MTMarcus T. · Senior offer · Meta

“$449.99 a year felt steep until I priced a blown onsite. It paid for itself in one loop.”

Frequently Asked Questions

Everything you need to know about the product and billing.

How do paid plans activate?

Paid plans are activated with a license key from your dashboard. After checkout, open the desktop app, paste the key into Settings, and the app will bind it to your current device.

What's the refund policy?

All sales are final. Aceloop ships as a digital good delivered on purchase, and the Free tier lets you run three full problems on your real coding platform before you put a card down. Both monthly and yearly subscriptions can be cancelled any time from your dashboard; access continues to the end of the billing period.

Is Aceloop worth $149.99 a month?

The round is the prize, and a blown round costs the offer. $149.99 for a month of unlimited solves is a rounding error against a single FAANG paycheck, and it covers every interview you take that month. Running a full loop? Plus Yearly at $449.99 drops it to about $37.50 a month.

What does "launch pricing" mean?

We call our prices founder pricing: locked in for the first 1,000 paying customers. Once we hit 1,000, prices rise for new sign-ups. We'd rather grow with engineers who pay than gate users behind the eventual price.

Will my price go up if I lock in now?

No. Your founder rate holds as long as your subscription stays active, through every renewal. If you cancel and resubscribe later, the then-current price applies.

Can I use it on multiple computers?

Your paid license is bound to one device at a time. If you move machines, you can reset the binding from the Subscription tab in your dashboard and activate again on the new device.

Which platforms does it support?

Windows 10/11 on x64 and macOS 11 (Big Sur) or later on Apple Silicon or Intel. Inside the interview Aceloop reads problems from any code surface on screen: LeetCode, HackerRank, CoderPad, CodeSignal, and custom browser tools.

Will it work on a corporate-issued laptop?

Usually no. Corporate laptops typically run endpoint-management agents that block new privileged desktop software without IT approval. Most candidates use a personal machine for the round.

Has anyone been caught using Aceloop?

Not in our testing and not in any public report we've found. Public forums document several competitors getting caught: Interview Coder on CoderPad Enterprise and Apple loops, Cluely on screen-share rounds. Aceloop's name does not appear in those threads.

Can I trust Aceloop with my data?

We don't store your interview problem, your code, or your test output. The model call is stateless on our side. We hold a hashed hardware ID for your license, your checkout email, and Stripe billing records. Nothing else.

How fast is the response time?

First token typically arrives in under 2 seconds; full response in 4-8 seconds depending on problem complexity. Kernel memory read of the problem and code is single-digit milliseconds. No screenshot, no OCR, no clipboard handoff.

Is this legal?

Using AI assistance during a coding interview is a question of platform terms of service and the company's interview policy, not criminal law. Whether to use it is the candidate's decision and the candidate's risk. We build the tool; the ethics are yours.
