1. I build Invisipilot, one of the tools below. I've tried to describe every tool from its own website, and I say where another tool is the better pick.*

Real-time AI interview assistants listen to your interview and show a suggested answer while the interviewer is still talking. In the last year the category went from a handful of tools to dozens. Here is what actually separates them, and how to choose.

What is a real-time AI interview assistant?

It is software that hears the interviewer (on Zoom, Microsoft Teams, Google Meet or a phone call), transcribes the question as it is spoken, and streams a suggested answer to your screen within a second or two. The better ones base the answer on your resume and the job description, so it sounds like your own experience rather than a generic textbook reply.

How should you choose one?

Four questions decide it:

  1. Can you test it in a real session for free? Some tools only allow a scripted demo or a mock interview before you pay.
  2. Subscription or pay-per-use? If you have two or three interviews a month, a monthly plan you forget to cancel costs more than buying a few hours.
  3. Where does it run? Desktop app, browser, phone, or all three.
  4. Does it handle coding rounds (capturing the problem on screen) as well as spoken questions?

The main tools in 2027

Final Round AI. The broadest suite: live copilot plus a large library for interview preparation and post-interview reviews. Desktop app for macOS 14.4+ and Windows. By its own FAQ there is no free trial of live sessions; you need a Pro subscription. Best if you will use the whole suite.

LockedIn AI. The widest device coverage: Windows, macOS, a web app, and native iOS and Android apps. Sold as subscriptions, monthly credit plans or a one-time Lifetime plan. Best if you want native mobile apps.

Interview Coder. Built for coding rounds. Desktop app for Windows and Mac, free to download. Best for algorithm-heavy loops.

Parakeet AI. Runs as a desktop app on Windows and macOS, in desktop Chrome, and in a phone browser. Has a free tier with no card. Sold as credit packs you use whenever, or as subscriptions.

Cluely. Started as an interview tool and now positions itself for meetings in general. Mac, Windows and an iOS app, with a free Starter plan with limited responses.

Sensei AI. Web-based copilot with a free tier of short (15-minute) sessions and support for 30+ languages.

Invisipilot (mine). Real-time answers based on your resume and the job description, on Zoom, Teams, Meet and any call app. It runs as a desktop app for Windows and Mac, in Chrome or Edge on any computer, and directly in a phone browser through the microphone. Every new account gets 30 free minutes of real live help with no card, plus a free ATS resume score and rewrite against a job description. After that you buy hours that never expire (for example 3 hours for $10) instead of a subscription. Weaker spots: it is a newer product with fewer public reviews, and it does not have native phone apps yet.

Which one is best for you?

  • Want one suite for preparation and live help: Final Round AI.
  • Need native phone apps: LockedIn AI.
  • Coding rounds only: Interview Coder.
  • A few interviews a month and no subscription: Invisipilot (hours that never expire) or Parakeet AI (credits).
  • Want to test a real live session free first: Invisipilot (30 minutes, no card) or Parakeet AI's free tier.

Is it allowed to use an AI interview assistant?

It depends on the employer and the interview. Some companies now run AI-assisted rounds on purpose; others forbid any outside help. Read the rules for each interview and don't use a tool where it isn't allowed. The tools are equally useful before the interview: run your answers past them, fix the weak ones, and walk in with stories you know well.

Bottom line

There is no single best AI interview assistant. Pick by how often you interview (subscription vs pay-per-use), where you interview (desktop, browser, phone), and whether you can test a real session for free before paying.
