The best AI tools for interview preparation are CoPilot Interview for scored mock interviews built from your résumé and the job description (we make it), Huru for free unlimited video practice, interviewing.io's free AI Interviewer for coding and system design, and Aced (formerly Exponent) for courses plus peer mock interviews. Add Yoodli if your delivery needs work, Big Interview if you want a structured course, and a free voice chat in ChatGPT or Gemini for quick, flexible reps.
No single tool covers every stage of interview prep. The list below says what each one is good at, what is free, and what it costs as of October 2026, so you can combine two or three without paying for overlap. If you are looking for tools that help during the interview itself, that is a different category, covered in our comparison of AI interview assistants. For résumé writers, job trackers and auto-apply tools, see our guide to AI tools for job seekers.

How we chose these interview prep tools
We compared what each vendor publishes: its features, free tier, prices and supported platforms, checked on the vendor's own pricing, FAQ and help pages in October 2026. We did not run a user survey, and we do not repeat vendors' own user counts or ratings. We left out tools whose main pitch is help during a live interview, because this page is about preparing beforehand.
Each tool had to do at least one prep job well:
- Spoken practice: asks questions and reacts to what you actually say.
- Feedback you can act on: a score, a rubric or specific notes, not just a transcript.
- Technical depth: coding or system design rounds, for engineering candidates.
- A real free option, or a price that is clear on the vendor's site.
The 8 best AI tools for interview prep, reviewed
1. CoPilot Interview: best for scored mock interviews from your own résumé
CoPilot Interview is a desktop app for Windows 10+ and macOS 12+ made by NeuraSense AI LLC. For preparation, the part that matters is Mock Interview: you paste your résumé and the job description, choose the level, how many questions (3, 5 or 8), the mix (behavioral, technical, system design, coding), your coding language and an optional focus. The AI reads each question aloud, listens to your spoken answer, and scores it out of 10 with what to fix and a model answer. A report card closes the session. Coding questions never auto-submit, so you can think in silence.
If you don't want to install anything yet, the browser AI mock interview has 113 real questions across 9 tracks, including behavioral, system design, coding, SQL and product. The site also has free prep tools such as the STAR story builder and the coding interview cheat sheet.
- Strengths: questions drawn from your résumé and the posting; every answer spoken aloud and scored; behavioral, coding and system design in one session.
- Limits: a desktop app rather than a website; the free plan caps you at 15 minutes a day; no human feedback.
- Price (as of October 2026): Free plan with 15 minutes every day and no signup. Standard is $14.99 a month (sale; regular $19.99) with 60-minute sessions and up to 100 minutes a day. Pro is $29.99 a month. See pricing.
- Fits: anyone with a specific job in view who wants to rehearse answers out loud, daily, for free.
CoPilot Interview is not affiliated with Microsoft Copilot or GitHub Copilot.
2. Huru: best free video practice for any role
Huru is free for job seekers, with unlimited mock interviews on its free plan as of October 2026. You pick a role from 242+ careers or paste a job post, answer on camera or audio only, and each answer gets a score out of 100 with suggested improvements. It also offers a conversational interviewer mode that asks follow-up questions and lets you set the length from 5 to 20 minutes.
- Strengths: no paywall; covers non-tech roles well; a Chrome extension builds an interview from a job listing.
- Limits: no native Android app (Android users use the web app); no human feedback; nothing on its site about a code editor for coding rounds.
- Fits: career changers, students and anyone outside software who wants volume at no cost. More in our Huru review.
3. interviewing.io: best for FAANG-style coding and system design
interviewing.io is best known for anonymous mock interviews with engineers from large tech companies. Its FAQ says those human sessions start at $179, depend on the subject and interviewer, and have voice but no video. The free part is the AI Interviewer, which runs coding and system design interviews in a FAANG mock style. The homepage says you can work through more than 200 problems from Beyond Cracking the Coding Interview for free.
- Strengths: realistic technical rounds; a free AI option for volume; full refund if you're unhappy with a paid interview, per its FAQ.
- Limits: engineering only; human sessions are expensive for repeated practice.
- Fits: software engineers a few weeks from an onsite. See our interviewing.io review.
4. Aced (formerly Exponent): best for courses plus peer mocks
Exponent renamed itself Aced in 2026, and its pages now carry a "formerly Exponent" label. It combines courses, a question database, peer mock interviews and paid coaching, and it is strongest for product management, system design and other tech-role loops. As of October 2026, the Aced pricing page lists a free Basic plan with sample lessons and 5 peer mocks a month; Pro at $79 a month, or $12 a month billed annually, with all courses and unlimited peer mocks; and Expert at $99 a month, or $20 a month billed annually, which adds AI mock interviews, AI interview feedback and an AI coach. Coaching is sold separately.
- Strengths: deep course content and real people to practice with; the annual plans are inexpensive per month.
- Limits: AI mock interviews are only on the top plan; peer partner quality varies; the refund window is 5 days from purchase.
- Fits: PM, TPM and senior engineering candidates with several weeks to prepare. Read our Exponent (Aced) review.
5. Yoodli: best for fixing delivery
Yoodli is an AI roleplay platform for communication coaching. In its interview practice, you enter a role and company, choose the interviewer's demeanor and answer out loud; the AI mixes in follow-up questions based on your answers, and with your camera on it comments on body language. As of October 2026, the Starter plan includes 5 sessions in total, Pro is $8 a month billed annually for up to 10 roleplays a week, and Advanced is $20 a month billed annually for unlimited roleplays.
- Strengths: strong on how you sound, not just what you say.
- Limits: much of the product is now aimed at company training teams; not built for coding rounds.
- Fits: candidates who ramble, rush or fill pauses. See our Yoodli review.
6. Big Interview: best structured course
Big Interview teaches first, then tests. It pairs video lessons with an Interview Simulator whose PracticeAI mode personalizes questions from your résumé or a job description, runs in a voice-only format like a phone screen, and returns a report on what to improve. VideoAI, a separate feature, analyzes recorded video answers. As of October 2026 it costs $39 for 30 days, $99 for 3 months or $299 for lifetime access, with a 30-day money-back guarantee and no free plan.
- Strengths: the most course-like option here; good for people new to interviewing.
- Limits: no free tier; engineers still need a separate coding tool.
- Fits: new grads, career changers and people returning to work. Many colleges and workforce programs license it, so ask before you pay. Our Big Interview review has the details.
7. Final Round AI: best for many practice formats in one app
Final Round AI is mainly sold as a live interview assistant, but its Practice Interview module runs eight scenarios: general, coding, system design, behavioral, product case, data and ML, salary negotiation and recruiter screen, with a debrief after each session. As of October 2026, its free plan covers setting up goals, uploading your résumé and parsing the job description; starting a practice interview needs a paid plan, and Pro is listed from $25 a month, with the lowest rate on longer billing terms. It runs on macOS 14.4+ and Windows.
- Strengths: the widest set of named practice formats on this list.
- Limits: no free practice sessions; month-to-month billing costs more than the headline price; older Macs are excluded.
- Fits: candidates who will use structured practice across several rounds and are willing to pay. See our Final Round AI review.
8. ChatGPT Voice or Gemini Live: best free do-it-yourself option
A general AI assistant can act as an interviewer if you give it the job description and clear rules. As of October 2026, OpenAI's Voice help page says Free users get limited access to ChatGPT Voice, which runs on web, iOS and Android, while paid plans list fixed daily hours. Google's Gemini plans page lists Gemini Live in the free plan, in the Gemini app for Android and iOS.
- Strengths: free, flexible, and useful beyond mock interviews: researching a company, generating likely questions, tightening a story.
- Limits: you supply the structure and the rubric; no consistent scoring; free voice limits can end a session early.
- Fits: anyone on a zero budget. Start with our ChatGPT mock interview prompts.

Which AI interview prep tool should you pick?
- You have an interview this week and no budget: CoPilot Interview's free Mock Interview with the real job description, plus Huru for extra video reps.
- You're a software engineer heading to an onsite: interviewing.io's free AI Interviewer for coding volume, then one paid human mock if you can afford it. Our coding interview practice page and the free Big-O complexity visualizer help with the theory.
- You're a PM or TPM with a month to prepare: Aced Pro on the annual plan for courses and unlimited peer mocks.
- Your answers are fine but you ramble or rush: Yoodli, then re-record the same answers until they fit in about two minutes.
- You're new to interviewing: Big Interview's lessons, if your school or workforce program gives you access; otherwise Huru.
- You only need behavioral practice: draft stories with the STAR builder, then rehearse them in a behavioral interview practice session.
Some of these products also sell help during live interviews. If you ever use one that way, follow the rules of the employer or assessment you're in — many people use it only to practice, which works on the free plan.
How to get more out of any AI interview prep tool
- Use the real job description. Generic questions train generic answers.
- Answer out loud every time. Typed answers don't train the skill an interview tests.
- Redo your lowest-scoring answer within a day. The second attempt is where you improve.
- Treat AI scores as coaching signals, not predictions. Our explainer on how AI tools score interview answers covers why.
- Add at least one session with a person before the real interview, for the pressure no AI fully recreates.
Rehearse your next interview out loud, free
Paste your résumé and the job description, and CoPilot Interview's Mock Interview reads each question aloud, scores every spoken answer out of 10 with a model answer, and ends with a report card. 15 free minutes every day, no credit card.

What is the best AI tool for interview preparation?
It depends on the round. CoPilot Interview (which we make) is strong for scored spoken mock interviews built from your résumé and the job description, Huru is the best fully free video practice tool, interviewing.io is best for coding and system design, and Aced (formerly Exponent) is best for courses plus peer mock interviews.
Are there free AI tools for job interview preparation?
Yes. As of October 2026, Huru is free for job seekers with unlimited mock interviews, CoPilot Interview's free plan gives 15 minutes every day including Mock Interview, interviewing.io's AI Interviewer is free, Aced's Basic plan includes 5 peer mocks a month, and ChatGPT Voice and Gemini Live have free plans with usage limits.
Can ChatGPT help me prepare for an interview?
Yes. ChatGPT can research a company, generate likely questions from a job description and run a mock interview by voice. The limits are that you have to supply the structure and scoring rules yourself, and free voice use is limited, so a dedicated mock interview tool gives more consistent feedback.
Is Exponent still available?
Yes, under a new name. Exponent renamed itself Aced in 2026, and its site now reads "Aced (formerly Exponent)". As of October 2026 it has a free Basic plan, Pro at $79 a month or $12 a month billed annually, and Expert with AI mock interviews at $99 a month or $20 a month billed annually.
Do AI interview prep tools work for coding interviews?
Some do. interviewing.io's free AI Interviewer runs coding and system design interviews, Aced has courses and peer mocks for technical roles, and CoPilot Interview's Mock Interview can include coding and system design questions in your chosen language. Video-first tools such as Huru and Yoodli focus on spoken answers rather than code.
How long should I use AI tools before an interview?
There is no official number. A practical plan is one full mock session for each round type you will face, a redo of your weakest answers, and at least one practice session with a real person in the days before the interview.
