CoPrep AI got something right that most of this category has not: buy minutes, no subscription. ClapAssist does the same and charges $5.99 for the 120 minutes CoPrep sells for $12. The trade is that their credits sit in the account forever and ours run for 30 days.
CoPrep is one of the few tools here not selling a subscription, so this is a comparison between two similar ideas rather than an argument about principle. That includes the part where they are better.
CoPrep AI: $12. ClapAssist: $5.99. Same amount of live interview time, same one-off payment, no subscription on either side. CoPrep's larger packs bring their rate to $0.06 a minute; our Interview Pass is 300 minutes for $9.99, which is $0.033.
This is the real trade. CoPrep credits never expire. ClapAssist pass minutes run 30 days from purchase. If you want to buy hours now and spend them across a job hunt spread over a year, CoPrep is built for that and we are not. If you are interviewing inside the next month, thirty days is longer than the search and you pay half as much.
CoPrep gives 20 free credits on signup. ClapAssist gives 10 free minutes, once per account, with no card. Theirs is more generous and it would be silly to pretend otherwise — but 10 minutes is enough to run a mock call and confirm the window really is invisible on your friend's screen, which is the one thing worth proving before paying either of us.
Both run as desktop apps that stay out of the way during a screen share. ClapAssist does it by having the operating system exclude the window from screen capture — WDA_EXCLUDEFROMCAPTURE on Windows, sharingType = none on macOS — on every plan including the free one, verified in a real Google Meet share on 3 September 2026.
CoPrep also offers $60 a month, $120 a quarter or $360 a year alongside its credit packs. ClapAssist has no recurring plan at all. Pro is $19.99 for 30 days as a single payment that does not renew.
Interviewing in the next few weeks: ClapAssist, at half the price per minute, and the 30-day window will outlast the search. Buying ahead for a hunt with no fixed timeline, or wanting the largest free trial first: CoPrep. Both are honest answers and the difference is genuinely about when you will use the time.
A page you can trust has to say this part too.
Their credits never expire; our pass minutes run 30 days from purchase. If you want to buy hours now and spend them whenever the interviews actually appear — next quarter, next year — that is the shape CoPrep sells and we do not. Buying a ClapAssist pass in a month you are not interviewing wastes it, so do not.
20 free credits against our 10 free minutes. If the plan is to test several tools thoroughly before spending anything, start there.
Their 840-credit pack is 14 hours at $0.06 a minute, sitting in the account indefinitely. Ours caps at 300 minutes per pass; past that you are into Pro, which is unlimited for 30 days rather than a bank.
Neither tool is a way around HackerRank, CoderPad or similar assessment platforms, which watch focus and keystrokes from inside their own page. CoPrep say the same on their own blog. Anyone in this category who tells you otherwise is selling you something.
Pay once. No subscription, nothing auto-renews. Prices show in your region's currency automatically. One account works on Mac and Windows.
For the same 120 minutes, yes: $5.99 against $12. The Interview Pass is 300 minutes for $9.99, which is $0.033 a minute against CoPrep's best rate of $0.06.
Yes. Pass minutes are valid for 30 days from purchase, where CoPrep credits never expire. That is the trade for paying about half as much per minute, and 30 days covers most active interview loops.
CoPrep gives 20 free credits on signup. ClapAssist gives 10 free minutes once per account. Theirs is larger; ours is enough to test the screen-share behaviour before paying.
Yes. The window is excluded from screen capture at the operating-system level on every plan, including the free one. It is not a paid tier.
ClapAssist does not — nothing appears in the participant list, because it runs entirely on your own computer.
No. Both are built for video interviews. Locked-down assessment platforms watch focus and keystrokes from inside their own page, and CoPrep say so on their own blog too.
No. CoPrep AI is a trademark of its owner. CoPrep prices and plan details on this page were taken from coprep.ai/pricing on 3 September 2026 and may change.
Each page states where that tool beats this one. If one of them fits you better, it is better to find out here than after paying us.
