What it is
A purpose-built interview copilot that runs two layers at once: an AI Copilot suggesting answers and an AI Coach alongside it. Answers arrive in STAR format, which is what behavioral interviewers are scoring against, and the vendor claims responses in under one second.
It has the widest device reach of the desktop-first tools: Windows 10 or later, macOS 13.1 or later, a web app in Chrome, Edge, Chromium, Opera and Brave, plus iOS and Android.
What stands out
Three things, all of them unusual. First, the competency-scoring report after a session, which tells you which competencies were weak rather than just what was said. That is the only feature in most of these products that makes your next interview better rather than your current one easier.
Second, language coverage: 45 or more languages and regional accents, with bilingual auto-detection so a conversation can move between two languages. If you interview in English as a second language, this is the most concrete answer published by anyone here.
Third, the breadth of the Coding Copilot: LeetCode, HackerRank, CodeSignal, CoderPad, HackerEarth, Codility and InterviewBit, with around twelve languages and a VSCode extension. It also covers online assessments, and offers LockedIn Duo, which brings a remote human helper into the session.
What is not clear
The free tier's boundaries. The vendor advertises that it is free to start with no credit card required, without publishing what you get. Third-party sites claim daily minute caps, but the vendor does not confirm them, so treat the limit as unknown until you hit it.
That is a small blemish on an otherwise well-documented product, but it does mean you cannot plan an evaluation precisely the way you can with a vendor that publishes session counts.
What it costs
Three shapes: unlimited plans, credit packs, and a lifetime option, with a money-back guarantee and credits that the vendor says do not expire. Credits that do not expire suit bursty interviewing, where you do three rounds one week and none for a month. We do not quote figures; check the pricing page directly.

Who it suits
- Candidates interviewing across languages or with a strong regional accent on either side of the call.
- Anyone whose loop includes online assessments or a coding platform beyond the usual three.
- People who want to improve round over round, not just survive the next one.
Who should look elsewhere
- Anyone who wants published free-tier limits before starting an evaluation.
- Candidates who only need help in one coding screen, where a cheaper specialist will do.
- People who want one assistant for all their meetings rather than interviews specifically.
Alternatives worth comparing
See LockedIn AI vs Cluely for specialist against generalist, LockedIn AI vs Verve AI for the closest match on features, and Final Round AI vs LockedIn AI for prep suite against live copilot.
Disclosed alternative: CoPilot Interview is narrower, a native Windows and macOS app with model choice per question and a permanent free tier that includes live use and publishes no session cap. We do not publish a 45-language accent list, and if that is your need, LockedIn AI is the stronger choice.
Frequently asked questions
Is LockedIn AI worth it?
It is one of the most complete products in the category, and the competency-scoring report genuinely helps you improve rather than just get through a round. It is worth it if you will use the coaching and scoring, interview across languages, or need coding coverage on a less common platform. It is over-specified if all you want is a fast answer in one coding screen.
Is LockedIn AI free?
It advertises that it is free to start with no credit card required, but it does not publish what the free tier includes. Claims on third-party sites about daily minute limits are not confirmed by the vendor, so plan on discovering the boundary during your own trial.
What does LockedIn AI cost?
It sells unlimited plans, credit packs and a lifetime option, with a money-back guarantee and credits the vendor says do not expire. Prices change and promotions are common, so check the pricing page. Credit packs tend to suit bursty interviewing better than a monthly subscription.
Does LockedIn AI work in a browser?
Yes. It publishes a web app supporting Chrome, Edge, Chromium, Opera and Brave, alongside Windows 10 or later, macOS 13.1 or later, iOS and Android. That makes it one of the few options if you cannot install software on your machine.
Is LockedIn AI good for coding interviews?
On published coverage it is the broadest in this category: LeetCode, HackerRank, CodeSignal, CoderPad, HackerEarth, Codility and InterviewBit, with around twelve programming languages and a VSCode extension. Check your specific assessment platform against its current list before the round.
What is LockedIn Duo?
A published feature that brings a remote human helper into your session alongside the AI. It is unusual in this category, and whether it suits you depends on whether you have someone qualified and available to sit in. Confirm how it works with the vendor before relying on it.
Want a published free tier instead?
CoPilot Interview's free tier is permanent, needs no card, and has no session counter.
