Final Round AI and LockedIn AI sell the same headline promise. Both listen to a live interview, work out what you were just asked, and put a suggested answer on your screen while the interviewer is still talking. Read the two homepages back to back and you would struggle to tell them apart.
The differences show up one layer down: where each product is allowed to run, how much of the job search each one tries to own, and how deep each goes on technical rounds. This page compares them on those axes, using claims from each vendor's own site rather than from the review farms that rank for these queries.
What each product actually is
Final Round AI: one opinionated loop, desktop only
Final Round AI is the more focused of the two. Its product is built around a three-phase loop that it repeats everywhere on the site: prepare a Goal from your resume and the job description, perform a live or practice interview, then review an automatic debrief afterwards. The live piece is branded Interview CoPilot, and the supporting pieces are Practice Interview, Interview Debrief, Screen Help and Stealth Mode.
Screen Help is the most interesting of those. Rather than only reacting to audio, it reads what is on your display, so a coding problem or a system-design brief can be pulled into the answer it writes. Stealth Mode is the company's feature for keeping the assistant window off a shared screen.
The constraint worth knowing before you buy is platform. Final Round AI's own product page states that Interview CoPilot runs in its desktop app on macOS 14.4 or later and on Windows. There is no browser-only path to a live session. It lists Zoom, Google Meet, Microsoft Teams, Amazon Chime, Zoom Phone, WhatsApp and Discord as calls it runs alongside, and CoderPad, HackerRank, CodeSignal, HireVue and LeetCode on the technical side.
LockedIn AI: wider surface, more moving parts
LockedIn AI spreads across more entry points. It publishes a desktop app for Windows 10 and later and macOS 13.1 and later, a web app that runs in Chrome, Edge, Chromium, Opera and Brave, and mobile apps on iOS and Android. For anyone interviewing on a managed work laptop where installing software is not an option, that browser path is the whole ballgame.
Its live feature is described as a dual-layer system: an AI Copilot writing answers and an AI Coach giving feedback in parallel, with responses formatted in STAR structure for behavioral questions. The company claims responses in under a second, and advertises 45 or more languages and regional accents plus a bilingual mode that detects which language each speaker is using without manual switching.
Two features have no equivalent at Final Round AI. Coding Copilot ships a VSCode extension that analyzes selected code on a keyboard shortcut, alongside browser coverage for LeetCode, HackerRank, CodeSignal, CoderPad, HackerEarth, Codility and InterviewBit. And LockedIn Duo brings a human into the loop: a trusted helper can observe the session and coach you through it. That is an unusual product decision, and it will either be the reason you choose LockedIn AI or the reason you do not.

Where Final Round AI is the stronger choice
Final Round AI wins on coherence. Every feature feeds the same loop, so there is exactly one thing to learn: build a Goal, run the session, read the debrief. If you are interviewing for one role at a handful of companies over six weeks, that structure does useful work. The debrief in particular is a real product rather than a checkbox, and reading three of them back to back tells you more about your weak spots than another hour of practice questions would.
Its screen-reading behavior is also better integrated. Because Screen Help writes full written solutions into a results panel rather than into the answer stream, a system-design prompt does not get compressed into a spoken-length answer. And the pricing is a single decision instead of a spreadsheet: a free preparation tier, then one paid subscription.
Where LockedIn AI is the stronger choice
LockedIn AI wins on reach and on technical depth. The browser app removes the install requirement entirely, which matters more than most comparison pages admit; plenty of candidates interview from a work machine with locked-down administrative rights. Mobile coverage extends that further.
On coding, the VSCode extension is a genuine differentiator. If your technical rounds happen in an editor with screen share rather than in a browser pad, being able to select code and send it for analysis on a shortcut is a different workflow from a floating answer panel. The broader assessment list, covering Codility, HackerEarth and InterviewBit, also matters if you are interviewing outside the usual US startup stack.
The multilingual work is the last real edge. If your interviewer has an accent that trips up ordinary transcription, or you want to think in one language and answer in another, LockedIn AI is the only one of the two that markets directly to you.
Pricing: two different bets
Both vendors adjust plans often, so check finalroundai.com and lockedinai.com for the current numbers rather than trusting any figure printed on a comparison page, including this one. The structures are more stable than the prices, and they are genuinely different.
Final Round AI runs a two-plan model: a free tier covering setup work such as goals, resume parsing and a prep checklist, and one paid subscription that unlocks live sessions. Its pricing page is unusually direct about the catch, stating that live sessions need an active paid subscription and that there is no free trial. You are buying a month of unlimited live use, or you are not using it live at all.
LockedIn AI offers several shapes at once: credit packs, an unlimited subscription and a lifetime option, with a money-back guarantee and credits its pricing page says never expire. That flexibility is useful if your interview volume is lumpy. It also means you have to estimate your own usage before you can tell which plan is cheapest, which is more work than most people want to do the week before an onsite.
A 20-minute way to decide
- Check your machine first. If you cannot install desktop software on the laptop you will interview from, LockedIn AI's browser app is the only one of the two that works. That single fact ends the comparison for a lot of people.
- Look at your next three interviews. Editor-based coding rounds point to LockedIn AI. Browser pads and behavioral loops point to Final Round AI.
- Count your months. A four-week sprint suits a single subscription. A search that will stretch across a quarter with quiet stretches suits credits.
- Rehearse before you rely on it. Whichever you pick, run two full practice sessions before a real call. Reading generated text aloud while sounding natural is a skill, and it is not one you want to learn live.
A third option worth knowing about
We build CoPilot Interview, so treat this section as the vendor talking. It is here because it fills the gap both tools leave: Final Round AI has no free live use, and LockedIn AI's cheapest path requires you to forecast your own usage.
CoPilot Interview is a native desktop app for Windows and macOS. It listens to the interview and shows suggested answers on your own screen in about four seconds, and it works with Zoom, Google Meet, Microsoft Teams and phone screens. There is a permanent free tier with no credit card, so you can test it against a mock interview before spending anything; paid plans start at $14.99 a month.
Two things are ours specifically. You can pick the model per question, choosing between GPT, Claude and Gemini depending on whether you are answering a system-design prompt or a behavioral one. And Interviewer Mode flips the product around for hiring managers who want structured help running the interview rather than answering it. There is also an AI resume builder in the same account.
We are not going to claim it beats both tools on every row above. LockedIn AI's browser app and VSCode extension are things we do not have, and Final Round AI's debrief loop is well designed. Try the free tier, compare it against the two above, and pick on evidence rather than on landing-page copy. Our FAQ answers the practical setup questions.
Frequently asked questions
Which is better for coding interviews, Final Round AI or LockedIn AI?
Both cover technical rounds, but LockedIn AI goes deeper. Final Round AI lists CoderPad, HackerRank, CodeSignal, HireVue and LeetCode, and its Screen Help feature reads the problem on your display and writes full coding and system-design solutions into the results panel. LockedIn AI lists a similar set plus HackerEarth, Codility and InterviewBit, publishes a dozen or so supported programming languages, and ships a VSCode extension that analyzes selected code on a keyboard shortcut. If your loop is mostly editor-based coding, LockedIn AI has more surface area. If your technical round is a shared browser pad and you want one clean panel, Final Round AI is simpler.
Do Final Round AI and LockedIn AI work in a browser, or do I have to install an app?
Final Round AI requires its desktop app. Its own product page states that Interview Copilot runs in the Final Round AI desktop app on macOS 14.4 or later and on Windows, so there is no browser-only path for a live session. LockedIn AI is more flexible: it publishes a desktop app for Windows 10 and later and macOS 13.1 and later, a web app for Chrome, Edge, Chromium, Opera and Brave, and mobile apps for iOS and Android. If you interview on a locked-down work laptop where you cannot install software, that difference decides it for you.
How much do Final Round AI and LockedIn AI cost?
Both vendors change their plans often enough that any number printed here would go stale, so check finalroundai.com and lockedinai.com for current pricing. What is worth knowing is the shape of each model. Final Round AI sells a free preparation plan plus a single paid subscription, and its own pricing page says live sessions need an active paid subscription and that there is no free trial. LockedIn AI offers several shapes at once, including credit packs, an unlimited subscription and a lifetime option, with credits that its pricing page says never expire.
Can I test either tool before paying?
Partly. Final Round AI has a genuine free plan, but it covers setup work such as goals, resume parsing and a prep checklist rather than live sessions, and the company states plainly that there is no free trial for live use. LockedIn AI advertises free to start with no credit card required, so you can sign in and try the interface before committing. Neither gives you an unlimited free tier, so budget for a paid month if you want to rehearse properly before a real loop.
Which one is better if English is not my first language?
LockedIn AI markets to that case more directly. Its Interview Copilot page advertises support for 45 or more languages and regional accents, plus a bilingual mode that detects which language each speaker is using without manual switching, and its homepage highlights accent recognition. Final Round AI does not foreground multilingual support in the same way. If you expect an interviewer with an accent your usual transcription tools stumble on, or you want to think in one language and answer in another, that is a real point in LockedIn AI's favor.
Is it acceptable to use a live interview assistant at all?
That depends on the employer and on how you use it. Some companies publish rules about outside assistance during assessments, and take-home or proctored tests usually have explicit terms you agreed to. The safest and most defensible use of any of these tools is preparation: rehearse with them, build a library of your own stories and examples, and let live prompts steady your nerves rather than supply knowledge you do not have. An answer you cannot defend in the follow-up question will not survive the loop no matter which tool produced it.
