LockedIn AI vs InterviewBoost.ai: The Honest 2026 Comparison
Short answer: LockedIn AI is a solid dual-layer copilot with a fast-sounding latency claim and a countdown-discount price tag. InterviewBoost.ai answers in 0.3 seconds, runs on desktop and mobile out of the box, and backs it with 25K+ landed offers. If you want proof over promo timers, InterviewBoost wins. If you specifically need a human "Duo" assist layer, LockedIn AI has that and we don't — yet.

Where LockedIn AI genuinely wins
Credit where due: LockedIn AI's "Duo" feature — a real human who can step in during a live session — is a differentiated idea nobody else in the category ships. If human backup during a live interview matters more to you than raw speed, that's a real reason to look at them. Their VSCode extension for coding rounds is also a nice touch for engineers who live in an IDE.
Where InterviewBoost.ai wins
- Speed you can verify in a sentence. 0.3 seconds. No "up to," no asterisk, no unverified third-party benchmark.
- Real pricing, not theater. Plans from $19/mo, listed on the pricing page. No 13-hour countdown timer resetting itself every time you refresh the page.
- Mobile isn't an afterthought. Phone screens, walk-and-talk interviews, on-the-go prep — InterviewBoost runs there natively. LockedIn AI's marketing centers on the desktop stealth app.
- Auto-apply is built in. One click across Greenhouse, Lever, Ashby, Workday and other company career sites — LockedIn AI doesn't compete here at all.
FAQ
Is LockedIn AI faster than InterviewBoost.ai? LockedIn AI claims ~116ms latency; InterviewBoost.ai states 0.3 seconds (300ms) plainly on every page. The gap is small and LockedIn's figure is a third-party-observed number, not an independently audited benchmark — treat both as directional until you test live.
Does LockedIn AI work on mobile? LockedIn AI's product is built and marketed around a desktop stealth app. InterviewBoost.ai supports desktop and mobile as core, equal experiences.
Which is cheaper? LockedIn AI's list price is $109.98/mo, discounted to $54.99/mo (or $39.99/mo on a 3-month commitment) via an ongoing promotional countdown. InterviewBoost.ai lists its prices openly (plans from $19/mo after a 1-week free trial) — no countdown, no code, no fine print about the discount reverting.
Does InterviewBoost.ai have a human backup like LockedIn Duo? Not currently. If a live human safety net is your top priority, LockedIn AI's Duo feature is worth evaluating.
Which one actually gets you hired? InterviewBoost.ai pairs applications with interview prep in one account, so the jobs you apply to become your mock interviews and live answers. LockedIn AI publishes a 58,000+ professionals user count but does not publish outcome metrics like offers landed.
