Pull up any “best AI interview assistant” roundup and the sticker prices seem friendly, right up until checkout. Cluely’s Pro plan lists at $19.99 but balloons to $149.99 once you hide the window, while Final Round AI’s $25-a-month rate needs a full year paid up front ($150 month to month).
1. Interview Copilot: one price, no limits
One flat subscription to interviewcopilot.ai’s live interview assistant costs $49 for a month or $149 for a full year and unlocks every feature: behavioral, coding, and system-design prompts, résumé-aware tips, and a glance overlay that never joins the call. No credits, coding add-ons, or per-minute meters. The desktop app runs on macOS and Windows and lists official support for Zoom, Google Meet, Microsoft Teams, and Webex.
Stealth is the marquee claim: the company says the overlay does not appear in screen shares, recordings, or screenshots, whether you share a window or a whole monitor, and there is no Dock or taskbar icon. The company says protection does not cover every managed device or proctoring system.
You can download and test the app for free, but a live interview needs a subscription. You can cancel renewal any time, and every payment carries a full refund if you email within 7 days of it. Run a dry-run screen share with the free download first. Three monthly payments total $147, just $2 below the annual plan, so a second interview cycle within 12 months makes the yearly option the better deal.
2. Verve AI: safest try-before-you-buy option
Verve lets you test live without a card: 3 × 15-minute calls plus 5 mock interviews free, enough to gauge latency and eye line.
- Standard: from $16.99 a month billed annually, 60-minute copilot sessions and unlimited mock interviews
- Pro: from $34.99 a month billed annually, unlimited 90-minute sessions
Refunds are limited to a verifiable technical fault on Verve’s side or a plan you never used, requested while it is active or within 5 business days of it ending. Bottom line: generous free testing, but the headline rates assume a full year paid up front.
3. LockedIn AI: everywhere companion
LockedIn covers a browser overlay, macOS and Windows apps, plus iOS and Android clients. Its Credits plan lists at $49.99 a month, billed every 3 months ($149.97 per quarter), against a standard month-to-month price of $139.98; that covers 400 minutes of live help a month, and the Unlimited and Lifetime tiers remove the meter at a higher price.
Monthly and quarterly plans are non-refundable once started; an annual plan cancelled within 7 days gets a partial refund, and a lifetime plan a full refund within 7 days if no session was started. Bottom line: broad device support, but the quarterly billing and the minute meter make flexibility cost more than it first appears.
4. Parakeet AI: pay-as-you-go pocket knife
Parakeet sells time in credits: $38 buys 1 credit, which covers an hour of calls (half a credit per 30-minute session), and credits can be used whenever. Unlimited plans run $78 for a week or $149.90 a month. Your first mock interview is free, so run a tech check before you buy.
Bottom line: ideal for one-off candidates who want to pay for minutes, not months.
5. Final Round AI: full ecosystem, check the checkout price
Final Round bundles practice rooms, résumé feedback, mock loops, and a live copilot. Its pricing page lists $150 a month month to month, $83.33 a month billed quarterly and $25 a month billed annually, plus a free plan limited to a basic interview report. Prices change often, so confirm the amount due before you pay.
Refund terms are narrow: a 72-hour refund window applies only to the first quarterly or yearly payment, and monthly plans are non-refundable. Bottom line: strong if you will use the whole ecosystem for a year; pricier for a single month.
6. Beyz AI: coding locked until you commit
The banner shows $24.99 per month, but that rate requires a 6-month prepay ($149.94). The flexible $49.99 monthly plan excludes the Coding Assistant; coding needs God at $32.99 a month billed quarterly ($98.97 up front) or the semi-annual Titan tier. A free tier is offered with no trial length listed.
Takeaway: prepay a quarter for a competitive coding rate; stay monthly and you miss the headline feature.
7. Interview Coder: premium, code-first firepower
Interview Coder lists Monthly Pro at $299 a month (1,000 usage credits) or Lifetime Pro at $799 one time; three months of the monthly plan come to $897, so the lifetime license is cheaper by month three. A free download lets you explore the app before paying, and it covers LeetCode, system-design and other interview types with real-time audio support. Refunds: none; all sales are final.
Bottom line: the most expensive option here, worth it only if coding rounds fill your calendar.
8. Cluely: meeting buddy, pricey stealth add-on
Cluely is sold as a meeting assistant; its free Starter tier gives limited AI responses and meeting notes. Pro costs $19.99 a month for unlimited AI responses and notetaking. Staying hidden from screen-sharing software needs Pro + Undetectability at $149.99 a month, or $449.97 over three months.
Bottom line: the $19.99 plan covers everyday calls; pay for stealth only if you must share your entire screen.
The hidden costs pricing pages skip
Annual-equivalent pricing. Verve’s “$16.99 per month” is $203.88 upfront. Multiply any advertised monthly price by the shortest term the site sells.
Coding behind an upgrade. Beyz’s monthly plan omits coding. Add any upgrade you need to your three-month budget.
Session caps. Verve Standard caps each call at 60 minutes, and LockedIn’s Credits plan meters 400 live minutes a month. With credit packs, budget about 20 percent extra for setup and overruns.
Stealth as an add-on. Cluely Pro appears in a full-monitor share; concealment starts at $149.99 a month. Check which share mode your interviewer will request: a single window, a full monitor, a recording, or a managed device. No product here has independent proof of hiding at every level.
Refund windows. LockedIn gives a partial refund on annual plans cancelled within 7 days and a full refund on lifetime plans within 7 days only if no session was started (monthly and quarterly plans are non-refundable), Final Round refunds only the first quarterly or yearly payment within 72 hours (monthly is non-refundable), and Interview Coder offers none. Interview Copilot gives a full refund if you email within 7 days of a payment, and its free download lets you test before subscribing.
Can interviewers detect an AI interview assistant?
Yes, sometimes. Detection depends on the setting.
- Ordinary video call: interviewers see only what you share plus webcam and mic, but may notice unnatural pauses or answers you cannot defend.
- Proctored browser test (e.g., HackerRank): the platform can log tab switches, capture your full screen, and flag multiple voices.
- Managed corporate laptop: IT tools can expose hidden windows and background processes.
- Second camera or full-desk view: reflections in glasses or a second monitor can reveal an overlay.
If the employer forbids outside help or uses proctoring software, assume they can catch it.
Conclusion
Interview assistants can calm nerves, but only when you understand the true costs, feature gaps, and detection risks. Use the picks table and hidden-cost checklist above to match a plan to your timeline and avoid surprise charges on day one.
