Best AI Interview Assistants in 2027
The interview tools worth your time going into 2027, from mock-interview coaches to live assistants, compared on what they help with, what they cost and where your data goes.
By Evin JohnPublished 6 min read
Most of what an AI interview assistant can do for you happens before the interview: rehearsing answers out loud, getting feedback on structure and delivery, and working through coding and system design problems under time pressure. For 2027, the strongest free practice tool is Huru for behavioral and role questions, interviewing.io's AI Interviewer is the best free option for coding and system design, and Aced (formerly Exponent) is the most complete course library. If you also want live help during interviews where it is allowed, Final Round AI bundles practice and a copilot in one subscription, and Natively is the option that keeps your data on your own computer.
This guide is about the whole process, weighted towards preparation. If you only care about real-time help during the call, our interview copilots guide goes deeper on that.
The short answer
- Free behavioral practiceHuru: unlimited mock interviews and scored feedback, free for job seekers
- Free coding practiceinterviewing.io: an AI Interviewer for coding and system design at no cost
- Courses and peer mocksAced (formerly Exponent): a question bank, courses and free peer mock interviews
- Practice plus a copilotFinal Round AI: mock interviews, debriefs and live help under one Pro plan
- Private, on your own machineNatively: a live assistant for your mock and real interviews, with local transcripts
Practice tools and live assistants are different products
"AI interview assistant" covers two kinds of tool that are often sold together. A practice tool plays the interviewer: it asks you questions, records your answers and tells you what to improve. A live assistant, often called a copilot, listens to a real conversation and suggests what to say while it is happening.
The distinction matters for two reasons. First, practice builds the skill you take into the room, while a live assistant only helps for as long as it is running. Second, practice is allowed everywhere, while live help is only acceptable where the employer allows it. Anthropic's guidance for candidates is a clear example: use AI to prepare, but no AI in live interviews unless they say otherwise. Assessment platforms check too; HackerRank's Proctor Mode looks for external AI assistants and overlay apps. Our copilots guide covers those rules in detail.
One practice tool many guides still recommend is gone. Google's Interview Warmup now redirects to a general interview tips page, which has done so since January 2026, and that page suggests practising with Gemini Live instead.

How we evaluated
We read each product's official site, pricing page and help pages on 27 October 2026. We did not take mock interviews on these services or run benchmark tests on them, so nothing here rates the quality of their feedback from our own use. Where a price only appears inside a checkout, we say so instead of guessing.
We weighted five things, in this order:
- Which rounds it prepares you for. Behavioral, coding, system design, or delivery and confidence.
- How you practise. Spoken answers with feedback, a coding pad, peers, or paid human interviewers.
- What it costs a job seeker. A free plan you can keep using counts for more than a short trial.
- What happens to your recordings. Whether the vendor says it trains on them, and whether you can keep them local.
- Whether it also helps on the day, where live help is permitted.
Because preparation carries most of the weight, the practice tools come first and the live assistants last. That is an ordering of the criteria, not a score.

- Pro $8 a month and Advanced $20 a month, both billed annually
- How it works
- Roleplay practice in the browser; also gives feedback on recordings you upload
Yoodli is a communication coach rather than a question bank. It runs roleplays, including interviews, and gives feedback on delivery: pace, filler words and structure. The free plan is 5 sessions for the life of the account, so treat it as a trial. Pro ($8 a month billed annually) allows up to 10 roleplays a week, and Advanced ($20) removes the limit and keeps your sessions out of AI training.

Live assistants for the interview itself
Where an employer allows AI help, or for mock interviews you run with a friend, a live assistant keeps your notes, stories and the job description in front of you. Two are worth knowing about from a preparation point of view; the copilots guide reviews ten.
Natively: best private live assistant
- Platforms
- macOS and Windows desktop app
- Free option
- Free for personal useFree for personal use. Bring your own API key (your provider bills you for usage) or run a local model through Ollama (no API charges). A short trial of the hosted Natively API needs no card.
- Paid plans
- Pro licence $39 a year or $79 once; hosted Natively API plans $8 to $35 a month
- How it works
- Desktop app that hears both sides of the call from your computer; no bot joins the meeting
Natively, which we make, is a desktop app for macOS and Windows. It is not a practice platform: it does not ask you questions. What it does in preparation is sit beside a mock interview, with a friend or on a peer platform, and show you what a strong answer would have included, so you can compare it with what you said. Its transcripts stay on your disk, which makes reviewing your own practice sessions easy. It is free for personal use with your own API key (your provider bills you) or a local model through Ollama; the Pro licence ($39 a year or $79 once) adds résumé and job-description context. See how it handles behavioral rounds and coding rounds.
Strengths
- Hears both sides from your computer; no bot joins the call
- Reads coding problems from the screen as well as from speech
- Your own API key or a local model; transcripts stay on your disk
Drawbacks
- No mock interviewer: you supply the practice partner
- Desktop only
- Résumé and job-description context need the Pro licence
Choose it if you want live help in mock interviews and permitted interviews without a subscription or a vendor holding your recordings. See Natively's plans.

- Web, macOS and Windows desktop, mobile
- Free option
- Free plan, with limits3 copilot sessions a month of 15 minutes each, plus 5 AI mock interviews.
- Paid plans
- Standard $44.99 a month ($16.99 billed annually); Pro $84.99 a month ($34.99 billed annually)
- How it works
- Listens to the interview and detects questions; screen-region capture for coding problems
Verve AI combines mock interviews and reports with a live copilot. Its free plan is one of the few that includes both, with no card. Standard is $44.99 a month or $16.99 a month billed annually; Pro is $84.99 or $34.99.
Strengths
- Five free AI mock interviews
- Three free 15-minute live sessions a month
- Desktop, web and mobile
Drawbacks
- 15 minutes is shorter than most interviews

Preparing for each kind of round
Behavioral and screening calls
Write five to eight stories (a conflict, a failure, a project you led, a hard deadline) and rehearse them out loud until each fits in about two minutes. Huru and Big Interview are built for exactly this; Yoodli then tells you how you sound. Our guide on using AI in a job interview covers what to prepare.
Coding rounds
Practise in a shared editor while talking through your approach, because interviewers grade the explanation as much as the code. interviewing.io's AI Interviewer and Aced's peer mocks both reproduce that format. Our technical interview preparation guide has a study plan.
System design
System design rewards structure: requirements, estimates, a high-level design, then trade-offs. Aced's courses and interviewing.io's AI Interviewer both cover it; worked examples such as our Uber system design walkthrough help you see the shape of a good answer.
Privacy: what happens to your practice recordings
Practice tools record your face and voice. Yoodli says plainly that on its Starter and Pro plans session data may be used to improve the platform, and that Advanced and above are excluded from AI training by default. Huru's homepage does not state a retention period. If you would rather keep recordings of yourself off other companies' servers, the alternative is to practise with a person and keep the transcript yourself, which is what a local assistant such as Natively allows.
Which tool for which situation
| Situation | Pick | Why |
|---|---|---|
| Student or new graduate | Huru | Free, unlimited practice; check whether your university licenses Big Interview too |
| Working professional short on time | Final Round AI | Practice and live help in one subscription |
| Coding interviews | interviewing.io | Free AI Interviewer in a real coding pad |
| Behavioral rounds | Huru | Scored answers across five qualities |
| Privacy first | Natively | Local transcripts; a local model keeps everything on your machine |
| Spending nothing | Huru | No paid plan for job seekers at all |
For every free option, including the trials and the bring-your-own-key setups, see the free interview assistants and copilots guide.
Questions people ask
What is the best AI interview assistant in 2027?
It depends on the stage. For free practice, Huru gives job seekers unlimited mock interviews with scored feedback, and interviewing.io's free AI Interviewer is the best option for coding and system design. If you want practice and live help in one paid plan, Final Round AI covers both under Pro from $25 a month. For live help that keeps your data on your own computer, Natively runs on your own API key or a local model.
Is Google Interview Warmup still available?
No. Its address has redirected to a general interview tips page since January 2026, and that page suggests practising with Gemini Live instead.
What is the difference between an AI interview assistant and an interview copilot?
A practice assistant plays the interviewer: it asks questions, records your answers and gives feedback. A copilot listens to a real interview and suggests answers while it happens. Practice is allowed everywhere; live help is only appropriate where the employer permits it.
Can I use an AI assistant during a real interview?
Only if the employer allows it. Some do, many do not. Anthropic, for example, encourages candidates to prepare with AI but asks for no AI help in live interviews unless it says otherwise, and assessment platforms such as HackerRank check for external AI tools and overlay apps.
Which AI tool is best for coding interview practice?
interviewing.io's free AI Interviewer gives you coding and system design problems in a real coding pad with written feedback. Aced (formerly Exponent) adds free peer mock interviews and paid courses.
Do practice tools keep my recordings?
Practice tools record your voice and often your face. Yoodli says session data on its Starter and Pro plans may be used to improve the platform, while its Advanced plan is excluded from AI training by default. Huru does not state a retention period on its homepage. Check the privacy policy of any tool before recording yourself.
