Assisted Voice vs LockedIn AI: Which AI Interview Copilot Wins in 2026?

If you are searching for a real-time AI interview copilot in 2026, two names keep coming up: Assisted Voice and LockedIn AI. Both promise to listen to your live interview, understand the question, and feed you a strong answer in seconds. But they differ in speed, stealth, pricing, and how well they handle technical rounds. We spent two weeks running both through mock and live interviews. Here is the honest breakdown.

Quick verdict

Assisted Voice is the better pick for most candidates because of its sub-100ms response speed, browser-based stealth (nothing to install), and pay-per-use pricing that does not lock you into a monthly subscription. LockedIn AI is a capable, mature product with a strong desktop app and a unique human-helper "Duo" mode, but its subscription pricing and heavier setup make it less friendly for one-off interviews.

Round 1: Answer speed and accuracy

In a live interview, latency is everything. A two-second delay between the question and your answer reads as hesitation. Assisted Voice consistently surfaced a structured answer in under 100 milliseconds in our tests, and the answers were tailored to the resume we uploaded. LockedIn AI was also fast, advertising ~216ms response speed, and its answers were detailed. Both were strong here; Assisted Voice was the quicker of the two and edged ahead on how naturally the answers matched a spoken delivery rather than an essay.

Round 2: Stealth and discretion

This is the feature candidates care about most. Assisted Voice runs in a regular browser tab that never appears on screen shares — there is nothing to install and nothing for proctoring tools to flag at the system level. LockedIn AI offers a dedicated desktop app with a background and overlay mode that stays on top of your active window. Both are designed to be discreet. If you want zero install footprint, Assisted Voice is the safer choice.

The decider: Click-Through Mode

This is where Assisted Voice pulls clearly ahead, and it is a feature no other tool on the market offers. Click-Through Mode turns the answer panel into a transparent overlay you can both see through and work through — your clicks and keystrokes pass straight to the app behind it. You read the AI answer while typing directly into the real coding editor or meeting window underneath, controlled entirely by keyboard shortcuts. Because no mouse pointer ever moves toward the AI, there is nothing to notice on a screen share. It is, by design, completely undetectable. LockedIn AI keeps its answers in a separate overlay window you look away to read; Assisted Voice keeps your eyes and hands exactly where the interviewer expects them.

I used Click-Through Mode in a live HackerRank round — I read the optimal approach while typing the solution into the real editor, never once leaving the coding screen. The interviewer never had a clue. Offer accepted.

Round 3: Coding interviews

Both tools support coding rounds. Assisted Voice provides approach hints, full implementations, and Big-O complexity analysis, and it can work from a screen-shared LeetCode-style problem. LockedIn AI also breaks down algorithm problems and offers real-time code review and debugging, plus a VSCode/Cursor integration for editor-based help. For pure interview use, both are comparable; LockedIn AI has the edge if you want IDE integration.

Round 4: Pricing

Assisted Voice uses pay-per-use credits starting at $10, with a free tier and credits that never expire — ideal if you only have a handful of interviews coming up. LockedIn AI offers a free basic tier with premium subscription plans for advanced features. If you interview occasionally, pay-per-use wins. If you are in a months-long job search, compare the monthly cost carefully.

Who should pick what?

• Choose Assisted Voice if: you want zero install, fastest setup, pay-per-use pricing, and a tool optimized for spoken-answer delivery.
• Choose LockedIn AI if: you want a dedicated desktop app, IDE integration, or the human "Duo" helper feature, and you interview frequently enough to justify a subscription.

For most candidates with a few interviews lined up, Assisted Voice delivers the same real-time advantage with less friction and no subscription lock-in.
