If you are choosing between the two: Interview Coder is the more serious stealth product and the more focused coding-interview tool, but the purchase is the problem. Its only monthly option is $299, metered by 1,000 credits with no published per-question rate, the free download ships without AI, and purchases are listed as non-refundable. Cluely is easier to start with, but its $19.99 Pro plan does not hide from screen share; that is a separate $149.99 monthly tier, and the product underneath is a meeting notetaker with interviews as one use case. Independent 2026 reviews report 20-plus-second responses from Interview Coder and 5-10 second responses from Cluely, so on latency neither wins outright.
Pick Interview Coder if you interview constantly and only for coding rounds, and the $799 lifetime plan amortizes. Pick Cluely if you also want one AI across meetings and sales calls and can pay for the undetectability tier. If what you actually need is one covered interview this week, there is a third option: Control ships invisibility, live voice, screenshot solving, and a phone remote on a $12 day pass, which is why it appears as the third column below.
