Run a Full 60-Minute AI Interview Copilot — Free

Most "free trials" for interview tools give you a locked demo and a paywall. InterviewOS does the opposite. Every new account gets the entire preparation suite free — forever — plus one complete trial live interview of up to 60 minutes with the real-time copilot. No credit card, no gimmick. This article explains exactly what's included, how to claim it in a couple of minutes, how to spend that free hour so it actually tells you something, and how it stacks up against paying a human coach.

What the free plan actually includes

The free tier isn't a teaser. The full prep toolkit is yours to keep at no cost, and it's the same toolkit paying users rely on:

• CV intelligence — upload your CV and get it parsed into structured achievements and evidence.
• Job-description match scoring — paste any job post and see how your background lines up, plus the gaps to address.
• A STAR story bank — build or auto-draft structured behavioral stories from your real experience.
• Flashcards for the facts, figures, and talking points you want at your fingertips.
• Mock interviews to rehearse answers out loud before the real thing.
• Company research and clean, shareable reports.

On top of all of that, your account includes one full trial live interview of up to 60 minutes with the real-time copilot — the same live assist that listens to the interviewer, transcribes each question, and streams an answer grounded in your own CV in under a second. It's the flagship feature, and you get to try it end to end.

A free trial should let you test the thing that matters. So the free plan gives you a full hour of the real-time copilot — not a locked preview of it.

How to claim it in two minutes

1. Sign up at /register with Google or an email address. No card is requested at any point.
2. Download the desktop app for Windows or Mac from the download page and sign in with the same account.
3. Upload your CV so the copilot has real material to ground its answers in.
4. Optionally paste a target job description to get a match score and surface the most relevant stories.
5. Open the Live page and start your trial session whenever you're ready — a scheduled interview or a serious mock both work.

That's it. The prep features are ready immediately, and your 60-minute live session is waiting for whenever you want to put the copilot to the test.

How to spend the free hour

Sixty minutes is enough to genuinely stress-test the copilot. Don't waste it on a warm-up you don't care about — treat it like the real thing, or use it on the real thing. Here's what to pay attention to while it runs:

• Speed — does the answer appear before the pause gets awkward? Aim to feel the sub-second turnaround, not just read about it.
• Grounding — do the answers reference your actual projects and numbers, or do they sound generic? A grounded copilot names your real experience.
• Honesty — ask it something your CV doesn't support and confirm it flags the answer instead of inventing a background for you.
• Behavioral pull — throw a "tell me about a time…" question and check that it retrieves the right STAR story.
• Scan and solve — if you're doing technical rounds, capture a coding problem on screen and see the worked, explained solution.
• Privacy — share your screen in Zoom or Meet and confirm the copilot window stays out of the shared view.

If you want to be systematic about it, run a proper mock first using the prep suite's mock interviews, then use the live trial on an actual interview. That way the free hour lands where it's worth the most. Our top 20 interview questions guide is a good source of questions to throw at it.

Free copilot vs. a $150/hour human coach

A good human interview coach is genuinely valuable — and genuinely expensive, often $150 or more per hour, booked in advance, gone the moment the session ends. The trade-offs are worth being honest about.

A human coach gives you warmth, nuanced feedback on delivery, and industry intuition. What they can't do is sit in your real interview with you, retrieve your exact project details in under a second, or be available at 11pm the night before. The copilot fills a different slot: it's on-demand, it's grounded in your own materials, it's private on screen share, and the trial costs nothing. For many candidates the smart move is both — a coach for strategy, the copilot for in-the-moment recall and endless practice.

One hour with a coach ends when the hour ends. The prep suite is yours forever, and the copilot shows up in the interview itself.

What Pro adds when you're ready for more

If the free hour convinces you — and it's designed to — upgrading is straightforward and priced around usage rather than locked features. Live assist runs on credits, where one credit is one minute of live interview.

• Pro — $29/month for 600 credits, which is ten hours of live interviews every month. Also available annually at $290/year.
• Premium — $79/month for 2,000 credits, over 33 hours a month, for heavy job-search seasons.
• Extras are metered too: a scan-and-solve costs 5 credits, a deep answer costs 2, and a 300-credit top-up is $19.
• A hard spend cap keeps you fully in control of what you spend.

You never need a paid plan to find out whether the copilot works for you — that's the whole point of the free 60 minutes. See every tier on the pricing page, and if you're weighing whether live help is right for your interviews, our guide to real-time interview help covers how it works in detail.

The offer is simple and there's no catch: the full prep suite forever and one 60-minute live interview, free. The only way to know if it fits your interviews is to run it.
